The net probetian of acrceptabla slugs was 241 tons whlch was 96 percent of the officisl forecast. Ihe lavler than foreca6ted prodnctian ass due principally to converting extirely to four-inch slug prodnetion tovard the end of the morrth. Bm lover of four-inch material combinad vlth the low yields resulted in mdnced production rates. A total of 223 tapa was canned as elght-inch slugs aud the mmmhing 18 tons as four-inch meterial- 'Ehe aanning yields were 85.3 percent and 65 percent, respectidy. me over4 canning field was 83.7 percent- The inprorcrent in the elgh%-iikh canning field resulted from a reduetion in the poor bond tspe rejeats. Ima four-inch Seld on the other hand was adversely affected by lnaxmwed poor bond typa rejeete vhich occurred in large PlIlljbex-8 with the defeote &Owlng as d pinholes in the aide of the veld. The cause has not yet been &terndned,

'&e canning of enriched uranium alloy fuel dugs contirmed with 9,582 slugs being cold canned vith a field of 75 percent. A total of ll,lOO lithium alloy target slugs was cold canned with a yield of 79 percent,

A canuhg yield of 56 percent vas realized on the hot press canning of 391 extruded fuel slugs dethe month, Poor banding vas the major reject cause.

Ihe tatd reactor hput plutanitnn production was 102.9 percent of the official forecast, and the outppt was U,3percent of forecast. The aver-dl reactor operating efficiency for the month was 78.8 percent. 'Ihe low operating efficiency was due principally to the outages associated with 24 ruptured slugs. Ihe established nmximm operating levels (excluding enrichment burnout) were increased a total of 64 MU dnring Ape including 15 at the B Reactor, 25 (PU and P-10) at the DR Reactor and 24 at the H Reactor. At the B Reactor the increase was attributed to improved flattening; at the DR Reactor to a revision of exit water temperature permissible limits (now based on average of highest ten tubes rather than the highest individual tube temperature); at the H Reactor to increased helium concentrations up to 50 percent as permitted by the production test on irrsdiation of thorium and U-235 alloy slugs for U-233 production. me program for discharging the normal irradiated uranium metal, at two concentrations as originally planned, continued with a total of 94 tons of metal being discharged at the low and 189 tons at the higher concentrations. Ihe P-10 prog~amat DE Reactor continued dralng 4- vith the charging of an sdditional 327 J-B tubes as part of the second P-10 irradfstion cycle. The P-10 program at C Reactor contipuhd drrring april without incidcat, and wlthout the cbargine of any Sdditionsl tubes.

'Ihe Irradiation of 12 J-Q (thorium) tubes, charged at H Reactor in March on a production test basis to Investigate the feasibility of large scale thorium inadistian, contirmed vith no difficulties during April.

During April 24 scrams occurred. Hineken of *the scrams at C, D, DR, and F Reactors were caused by mrml Fanut system dSficulties. (he scram st F Reactor resulted from an electrical power surge on the BPA system. Two scrams occurred at H Reactor, opt caused by an electrical fin in Bo. 22 vertical rod switch in the control room, and one as the result of mallunctianing of a temperature monitorixg instnmacnt on a production test recirculation tube. One scram at C Reactor occurred as a result of improper bg-passing of the B-C Reactor Safety circuit inter-tie vhile making revisions to tae B Reactor portion of the inter-tie. Qle lov pressure scram occurred at D Reactor on a water Qudity production test tube when the supply pump failed causing a mntary drop in pressure. Total outage tim charged to these scrams was 8.0 hours.

One process tube leak occurred at the C Reactor in conJunction with a ruptured slug. During reactor operation, subsequent to the tube replacement, a total of 285 gallons of water were rerPoved from the reactor.

The F Reactor continued to operate during &ril Kith a distorted flattea pattern to compensate tor the loss of reactivity (approximately 100 ih) attributed to boron in the graphite. lhis incident resulted from a horizontal rod and thimble leak late in February.

Durlng a gas leak testing program at B Reactor on April 29, horizontal rod thimbles No. l& E, 4 and 7 were found to be leu. Rods 30. 4 and 7 were removed from serrrice and the thimbles blanked off pewrepairs scheduled for the next outage. At that time, blanking oif of A and/or B thimbles for subsequent replacement is planned. Other horizontal rod work durlng April, necessary because of thinrble leaks, included removal and replacement of No. 6 thimble at B Reactor, and removal from , s&ce of m0. 5 rod at DR Reactor vith blanking ofl of the thimble.

On April 28 the ferric sulfate water treatment process was changed to the alum- activated silica coagulant process at B Reactor. All areas are now using alum- activated silica in the preparation of process water. 2he first irrsdiated J lpaterial of the pres& J-EJ p~ogrsunwas shipped off-site on April 12.

The total reactor input plufonium production during April was 102.9 percent of forecast, although only 96.6 percent of the March production. April plutonium production was lower than March production primarily because of the shorter month, and because a greater percent of the total reactor input production was devoted to the P-LO program. Outages aasoclated with 24 rupt~~ewere responsible for a law time apexuted efficiency, 78.8 percent, which, although approximately three percent higher than in March, was approximately LO percent below recent experience.

Reactor plutonium output production during April was 112.3 percent of forecast as a result of revision of discharge schedules because of rupture outages.

It was recammhadcd In the investigation that when an effluent basin is dratned in the future the walls and buttom of the basin should be kept vet. Methods for doing this are being investigated. The inveetigation of this incident is contained in document ~~-71565. A potential Radiation Incident occurred at F Reactor when a pile operator attempted to move a wrapped process tube channel broach *an the cushion chamber corridor to the wash pad. As the broach was gicked up, it slipped out of the wrapping and struck the floor, dlslodglng contamhatian which became air-borne as a result of strag ventilation drafts in the corridor. The operator received 6kh cmtamination of k0,OOO c/m on the side of the nose and 1,500 c/m In the left eye and ear. Operators on the five and 30-ioot level landings also received minor skin contamination. Flnal classification and additional investigation await urinalysis results . The effluent "apor problem at B Reactor, which has been magnified by the Larger flaw permitted by the installation of venturis, continued durlng 4~ril. Removal of the baffle in the effluent line did nut aid in solving the problem. Pending installation of a vapor vent line at B Reactor, a portion of the B Reactor effluent flaw will be directed to one of the lO7-C tanks through one of the C Rerctar effluent lines.

At H Reactor, following the removal of a process tube cmtaining a ruptured regular uranium slug, dose rates as high as 350 mrads/hr were observed at the surface of the storage basin as a result 02 gas escaping from the slug.

In the TBP Plant, a new production record waa established as 302 tonr of tamaim were proaeseed despite slpniilcant down tW axpsrihnced in both extraation Unes due to equipment fcrilures in the feed preparstlon and waste concentration sections. Maximum produutlon rates of 15-1/2 tans per &y were atklned and total pmdwtlon from the plant averaged approximately 10 tom per day for the entire month of April.

Production through the UO Plant was a new record as 420 tons of uranium were processed. bur calcinations were conducted in one of the newly installed gas ffred iuFnsces (Luckey Pot No. 20). The initial calcinations produced powder posaessing good physical charaateristlcs but low reactivity. Temperature and feed con- centrrtlon rdjustmcnte for later crlciaations produced powder of acceptible quality. d. Waste Metal Removal

B. Equipment Experience DECLASSIFIED 1. Operating Continuity

Redox down time totalled 218 hours and was primarily for crane decontamination and maintenance. Replacing the G-5 agitator and 1A column feed valve also contributed to the total down time.

Total down time for the TBP Plant was 110 hours for A Line and 19.5 hours for B Line. The outages were causedby failure of the condenser vent blower motor, two waste concentrator pumps, and the A Line RA column feed pump.

2. Inspection, Maintenance, and Replacement a. 60 Ton Crane - Redox Decontamination and major maintenance repairs of the Redox crane were accomplished during the plant shutdown of April 1 - 8. Repairs included replacement of the main hoist motor generator set and trolley festoon cables; installation of a new vent duct and cab filter system; repair of the left hand optics system.

b. 1A Column Feed Valve Failure - Redox , A ruptured IA feed valve bellows forced building shutdown on April 29. The valve was replaced with a redesigned inverted seal type valve which is expected to give better service and eliminate the possibility of similar failure.

C. D-1 Precipitator Tank Failure - T Plant me lanthanum fluoride by-product precipitator tank (D-1) in the Concentration Building developed a bottom leak on April 26. Re- placement was made with the A-1 tank from the B Plant Concentra- tion Building. The D-1 tank had been in service siilce start-up, and was the first lanthanum fluoride process tank in either B or T Plant to fail.

a. RA Column Feed Pump Failure - TBP

The A Line RA column feed pump failed on April 12 and replacement was made with a spare unit on April 14. High radiation levels have prevented inspection of the unit to determine cause of failure.

e. Waste Pump Failure - TBP

Both waste transfer pumps in the WR-001 Tank (waste pump tank to East and West Area Tank Farms) failed within a period of one week. Bearing failure resulted in locked impellers. Replacements were made and subsequent operations have been satisfactory.

Heated RC Calm Extractant - TBP

Employins Rc Column extractant heated to 55 2 5O C was continued in AprU. Analysis of the RC Column waste losses versus RC Column aqueous to organic ratio ha8 indicated that the extractant flow reduced to 50s of norad flowsheet requirements is a practical limitation. Ihe control aqueous to organic ratio as determined from plant data was 0.65 and was further substantiated by a 0.60 Wue obtained from luboratory equilibrium data. me process is now set at a RC column aqueous to organic ratio of 0.70 to allow for fluctuations in flow rates and temperatures. e. Reactivity Rocess Test - U03 One carload of uranium oxide has been produced incorporating sul- fsmic acid as an additive to Improve the oxide reactivity. Be- vious attempts to produce large quantities of this type oxide had resulted In severe product caking in the calcination furnaces. Reduction of the sgitator work load by decreasing the furnace charge eliminated essentially all of the caking problem. A reactivity o? 1-30 and a percent vF1, conversion of 89.51 vere achieved for the carload shipment. 1. Process Tests and Revisions (Continued) f.

Runs processed to date confirmed the apbion that the dissolving and extraction sections would determine the production capacity of the Bismuth Phosphate Plant under the 2l.5 IWD program. The present equipment is being modified to give mrximum flexibility in these two sections, and pro- Cess ahlnpcs are being investigated to give the minimum time cycle far processing. . h. 'Plsk I3 Re-hydrofluorFnrtlon Rate - 234-5 & April, 186 runs were processed through Task I1 to the in- epactlbn station. Only five runs were re-hydrofluorinated, of which two were caused by equipment difficulties. Excluding these two runs, the re-hydrofluorination rute is 1.64 and over-dl it is 2.7%. This is the lowest re-hydrofluorinstion rate ever achieved on the RblA Line under routine operating conditions and is rttributed to preheated process gases, a 4500 C maximum cycle, and the excellent condition of Task I1 equipment which has resulted from a coordinated preventive maintenance program. 2.

Purar design is 98.5s complete compared with a scheduled 1009. Construction of Pmt A as of April 15 is 30.55 complete and is essentially on schedule. Ihe estimated ready-for-operation date continues to be August 1, 1955; however, this may require chang- ing to a more optimistic date In the near future if the construc- tidn contractor continues to stay on schedule. The official scheduled date for construction completion is still January 1, 1955. A revleion request to increase the condensing capacity of the 241-A tank fsnn md to make other alterations to take care of %urplng" was approved by the Project Representatives and the Design Council. Be AEC has not yet approved this revision. To achieve the required condensing capacity of ~5,000,000Btu/hr., the ewace condensers as presently designed are to be cancelled and replaced by a direct buried contact condenser and an installed spare. Capacity for condensing the vapors from the waste storage 2- - tankst will thus be increa3ed by approximately five times.

A reesian request was recently approved by the Design Council to co-ordinate the execution of construction work of Project CA-513-A and CG-558 and to minimize duplication of work as well as eliminate work no lower necessary. The work involved installation of additional pump- capacity in the 18~~and 18~~pump houses to provide &.equate raw water to the 200 Areas. Project 03-558 will install a nlmiber of pumps in these pump houses, thus eliminating the need for some of the pumps which were to be installed by Project CA-513-A. More pumping capacity will be available for export line serPice as a result of Project CG-558, The effect of this revision will be to delay the CA-513-A phase of the work until approximately April 1, 1955.

A steel ring (diameter 32", width 8", 1/2" plate) fell from its stored position on the 8" side and struck the employee's foot above the aafety cap in his shoe. As of April 30th the Section had worked 184 days without suffering a lost-time injury. D. Radiation Experience

Three Clasa I radiation Incidents occurred. These involved: (1)personnel exposure to airborne ruthenium contamination in the 222-5 laboratory when D. Radlatlon Experlance (Continued) . a non-routinS sample contalnlxq ruthenium vas improperly stored; (2) uncontrolled spread of contmlnatlon when a leaking connector in the 155-TX diversion bax allowad metal waste to flaw through the previously falled crtuh tank .nd to pernolate to the ourface of the ground; (3) cOnt.minrtian -red and possible inhlltlon of plutonium as result of f.ilura to datact --tion following use of a ruptured hood glove in the 231 BulUlng. A probable Class XI incidext Fnlolvlng a small localized exgosure estimated to be &ewe the permissible limit occurred on April 30 as a result of epot akin md clothing contunlnaticm during routine operations in the 222-5 laboratory. Ihe exact exposure had not been determined at month end.

Blowbacks of contlminltlon Into the Redox pipe gallery lines consti- tuted a earlow potentirl for personnel exposures. Five separate blowbacks ocrarirrad in April, four of which involved lines from H Cell and cme involved the air line to the LB column feed v8l.m. The exposure problem during pot unloading in the 9Plant was significantly -zed through the use of shielding devices during the unload- iq operation.

APRIL 1954

The nechmicrl propertier of Irradiated uraaium hewe been determined in a controlled pmduetion test conducted at -. mi= irrsdiated at 150-175O c to 310 XWD/AT and -tad at rocm temperature mme than doubled in yield strength (32,000 to P,W psi), lost 25 percont in ultimste tensile strength (104,000 to 76,000 Mi) and ww a factor of iifty leas ductile (17.0 to 0.36 percent eloqptiun) than the came material unifiadiated. These data are the fir& of a series whlch Will provide quantitative engineering data needed to design 8luga having the lmst pO8Elble stresr level in a given environment. ThermLL rtre#rer in solid and cored Qltaraally oooled fuel elementa have been -zed umbg recently derived methodis ud presently available mechanical property data for anirradiated uranium. For 1.36 inch outer diameter fuel element8 operating at 50 kw/ft in l0S0 C coolant temperature the mi- mum circuafarentirJ. tensile rtresr ai a solid fuel elawat i8 43,800 psi. On carlrtg the stress is reduced by 19, 26, and ba percent for core diametem of 0.2'72, 0.544 and 0.816 inch, respectively. Several types of hollow slugs were tested under cyclic strain induced by a theral gTadicnt (us- the vood.plitter). Resultant shape and dimensional changes indicated that substantial relief was obtained a6 a result of coring. None of the cored slugs split under the conditions wed, Fabrica- tion of hollow sluga and canpanion solid pieces to be irradiated under a production test is about 30 percent complete. These pieces are being made by coring half of an eight-inch beta treated uranium slug and wing the remaining half a6 solid cumpanion metal. Uranium plugs are being heli-arc welded into counterbored'recesses in the slug ends to exclude Al-Si from the hole during lead-dip canning. An inside diameter of 0.375 inches is being used in there pieces since prel- calculatlons lead to the conclusion that this size rcSult8 in a wimum stress relief with a minimum loss in reecti- vity. There ahould be canned and charged Into the piles during May. Structural damage in Irradiated uranium as studied by X-my diffraction is undetected at 150 MWD/T exposure but is revealed by definite line broadening at 1000 MWD/T exposure. The exact type of structural damage has not yet been ascertained.

Studies directed toward identification of ruthenium species in Redox solution have shown that the head-end treatment almost completely destroys anionic and huone-soluble forms but that solid ruthenium, either precipitated or absorbed on "02, appears In appreciable quantities--approximately half the ruthenium in the E-1-MO solution and most of that in the ICU appears to be present as a solid. The head-end treatment Is beneficial and should be retained but improvement in clarification of the H-1-MO is needed.

Scavenging treatments were carried out wlth stored first cycle Bismuth Phosphate waste supernate. Acidification of the sample to pH 8.5 and treat- menewith nickel ferrocysnide effected a cesium decontamination of 1200 and yielded a solution well belov cribbing levels.

Improved instrumentation is permitting definition of the source of ruthenium d6610n; measures are being studied to repress the evolution of ruthenium vhich occurs Immediately upon addition of potassium pemaqanate to the cxidizer ryrtan. no presswe surges were observed at the tank farm during the month. Iaboratory studies on this problem suggest that the system nrny be mceptible to control by regulation of the cauetic concentration. e hate metal recovery plant operations were notable for high production and low waste losses, high on-rtream efficiency and high product quality which were indiv1duaX.y the best achieved since plant atart-up. Single cycle operation was adequate for processing the feed which had an average estimated age of 3.8 years. Water sluicing and supernatant acidification were successfully employed in achieving a new record uranium weekly removal rete. An experimental carload lot of uranium-triaride was produced wherein sulfur was incorporated (0.08 wt. peraent sulf8mic acid addition) to produce material with the reactivity of 1.3 verstu nornul valuer In the range 1.0 to 1.1. The gas fired Luckey type pots were placed in trial operation. Other than high pcrwder entrainment from the fume syrtem it appesrs that they will be satisfactory after further investigation and definition of optimum processing condition?!. Laboratory studies of the completely acidic dissolution procedure for slugs and jackets were directed primarily at control of the hydrogen content of the out-gas stream; it appears that the presence of uranyl ion or aluminum ions will pennit control of the hydrogen content in the off-gas stream.

During April, the piles were limited primarily by outlet water temperature determined by slug corrosion effects. lev high levels were reached during the month at B, D, DR, and H. Increases in river water temperature caused power level reductions toward the end of the month. Thirteen eight-inch and seven four-inch normal uranium pieces failed during the month. Four of these failures were cap failures, one was a compound cap failure, five were uranium cleavage failures, three were side failures, two were non-classified, and the other five we stuck in the tubes and have not yet been inspected. One failure of a Al- $35 alloy "J" piece occurred at DR Pile this month. A three-inch longitudinal split in the can wall was noted.

Pover Iavel Limits

Dura April, the pilea vera limited primrily by outlet water temperature determixmd by slug corroriorn affects. D and H Piles are authorized by production test to operate at 95 C and other pilee at 90 C. C Pile is limited to a nmximupl authorized tube per. Nuv high levelrr were reached during the month at B, D, llR, and H. Increarer In river water temperature caused per level reductions taaard the end of the month. Slug Rupture grpSrience in Ayril Thirteen eight-inch and revan four-inch normal uranium pieces failed dura the month. Four of these failurea were cap failures, one was a compound cap failure,'five were uranium cleavage failures, three were side failures, two were non-cfaaeiiied, and the other five were stuck in the tubes and have not yet been inspected. Three of th four cap failures occurred in eight-inch, lead dlp cmnned pieces charged under Reduction Test 313-105-23-M. Ths80 were the first fallwee of thir typ to occur in eight-inch metal.

Of the thirteen failures of oight-iPch pieces, five were Production Test 25-M metal, which failed at exposures between 500 and 600 EiwD/cy, and one was a lead dip canned piece charged under Production Test 3l3-1@-7-M, which failed at an expoeure of -1200 MWDfi. Ten of the railurss this month occurred at exposuree above 650 MWDb. Trradiatian Behavior of Lead Dipped Slugs - At the present time, the indicated rupture rate forProduction Test 313-105-2544 metal is somewhat higher than that for eight-inch, triple dip canned slugs, perhaps by as much as a factor of two. However, there has as yet been insufficient experience with this metal to allow a firm statement as to its rupture rate. Also, it is noted that four of the five Production Test 25-M failures whose canning histories are presently known were from the Hanford cast lots which comprised approx- izaa-tely forty per cent of the metal charged under tbis test. The Hanford Cast metal has, in the pest, shown e rupture tendency greater than that of metal cast elrewhere, expocially in the contribution of cap failures. Thus the current perfozapnce of leed dip canned metal may not be rspmsentatiw of the mer4ll perforpmco vhlch mtght be experienced with this material being irradiated a8 st.n&rrd production -tal. Bail& of Bon-Ulmlun badinus - Ons f'all.of a alloy, "J" piece occurred at LIR P ile th ir month. A three-inch longitudinal rplit in the can vel1 was noted. Thir piece had been under lmediation for approratsly one and 0x10-half month8.

Roductian Test lO3-$76, "Preliralnary Txmdlatiom of J-Q Column" - Thirteen tubes containing nbeteen alternate "J" and thorim pieces were charged at H Pile on March 14, 19%. '50graplrite heating problem n&ed last lpopth MS relieved by flattening adjustmsnts made on March ,28, 1954. Tbs test ha8 proceeded without incident. Production Test 105-532-A-4 - Tncreaaed slug powers were investigated at C Pile by lrradiat three tubes each containing tuelve uranium slugs enriched to 1.75 per cent%. Bhxlmnn 61% powers calcbted to be 75 W/ft were obtained as were core tempemture8 up to 700 C. Orre piece failed at an exposure equivalent to 500 EwD/AT, based 09 the hottest #lug, and all tubes were discharged. Tt is of intsre8t to note that hollm slugs of the 8ame material and charged at the same time have continued to operate eatisiactorily at about ten per cent lower output. Their equivalent exposure is pow about 600 MWD/AT. Production Test 105-566-~,"Eiiect of Therm1 Cyclisg on Slug Failure Tncidence" - On April 9, three H Pile fringe tubes were charged with two enriched uranium pieces and 28 normu1 uranium pieces each. The enriched piece6 in two of the tubes were charged adjacent to a horizontal control rod and are be- thermally cycled, in two hour cycles, by moving the control rod tip in and out past the tubes. The third tube ita being ured as a control. The enriched pieces Operate at powers of approxinntely 30 gW/it of uranium, sUghtly ~essthan the calculated high slug powers in the flattened region of the pile. These piece6 have now been subjected to approximately 220 cycles. Production Test 105-551-A, "High Eq08me Thorium" - As the exposure of thorium pieces proceeds, at generation per slug increases because of the formation of fissionable $9s . This test authorizes the expoeure of thorium flattening columns to high expoaures to obtain data on the rate of heat generation. DECLASSIFIED rupture occdin a tube at 1220 EMD/AT, although others haw been exposed above 1900. 'phn piece bas not yet been exnmined. Production Test 1@-$62-A, "P-10 Ttrediatlon at C Pile" - The choice of piles to be used for aqy rcrturs P-10 pFoductian will deyond on the ability of the fuel and target rlug8 to operate mrcceesfully at high tube powers. This is being iwestigpted at C Pile in ths central zone. Sirty tube have operated 8-0 tfis d Febmq. Forty contain hot-prersed iubl SlwSy the balance being cold-canned or Al-Si canned. The maxhwn mnttube axposure ir roughly 43 MID, or sli@tly leu6 than ons-haV of goal exposure. Ths tube per8 of the J-R charger are about 88 per cent that o!C the rurrounding norm1 uranium.

The paraffin mod originally has been replaced with lucite because the paraffin tended to flow and because the lucite permits the location of more detectors. In the third step, the thermal flux peaked at about 1.25 inches of lucite, then fell off with a relaxation length of about 5.6 cm, relatively close to that expected for pure therm1 dlffuaian. With a total of one-half of the masanite removed frw the test slabs, the thermal flux in the outer layers has gono up a factor ai approximately 1000 in the outer cyclea. The gam intensity 18 increasing at a greater rata than would be predicted from density changes, indicating that capture radiation frtm the outer regions of the biologicai rhield has become prodoaninant.

COOl~-by-BOiling StndieS Cooling-by-boiling tests with a C Pile annulus have been completed at 100 and 250 psig rear header pmrrurer for uniform heat generation tube pawers of 250, 400, and 600 gW and inlet water tempsraturer of about 10, 100, and 150 C. Wee torts were aimed at demonstrating the feaeibility of cooling slugs by vaporization of the cooling water as well as determining the mix- Imun steam qualities which could be attainsd. The data may be rwmrized as follows: A. Cooling-by-boiling war porsib& under every combination of conditions mentioned above. E. Ths miniFrm flaw rates under which cooling wae rtable varied from about two to fourteen gpu, de*nding upon the conditions. C. Calculations baaed on these minhnu flaw rater gave steam qmlitier at the end of the "active zone" of about 15 to 70 per cent by weight. In general; the highest qualities were obtainad at (a) lwest powers, (b) highest rear header plessure,.and (c) lowest inlet temperature. However, "pgwer" predominates as the meJor controlling factor in the quality which can be reached.

Relatively minor modifications are being made to the equipmsnt which should permit further testing at 500 psi rear header pressure. It is estimated that about two weeks will be required to make the changes. Subsequently, efforts will be made to find moans for raising the pressures to 800 psi.

Major Equipment Modifications

Orders were placed during the month for a 2500 psi, 150 gpm recycle pump, a make-up puznp, and a amall, self-contained water treatment plant. These items will be used to modify the full scale process tube mock-up to pennit cooling etudies at very high pressures. Considerable difficulty was encountered in securing a pump design with the proper gland leakage characteristics; however, it is believed that the problem is essentially solved now.

The design ha6 been completed and bids have been called for stainless steel high pressure process tubes to be used on the mock-up. These tubes are Of DECLASSIFIED sizes to acconmodate heater tubes having diamsters ranging from 1.4hh O.D. to 2.64" O.D. In addition, ths derign of heater tube8 is proceeding.

The rtcommndation was made previously that the cone screen for K Pile consist of a simple cross-wire. Apparently the Design Council approved the use of this type of screen upstream of the venturi, but it also requested that means for installing a mller -ah scrwn downrtream from the venturi .be investigated. A screen of thie Utter type MI designed and is presently be- tested. EIpsrimantal studies are being made of the effect of high flow rates (25 to 40 gpm) through the rear cross-header parkor fittinge of the old piles. The fit%-s have a rmaller I.D. than the pigtail, and a loss of static pressure occurs in them. This, in turn, lead8 to local boiling, cavitation, and water hammer. Tt is felt that the water hamor effects may be serious at the higher rates, and the studies of thir effect are continuing.

The perfonaances of two venturis that were designed to include the inlet cross-header fittings as part of the venturi were determined. These venturis are for use with Project CG-558. Further work is being performed to determine the effect of cross-wire screens on pressure loss. Work is progressing on a schedule which will allow completion of the 189-D Hydraulics Laboratory about the middle of May.

Tt war found that pile oafety would not be cwpromired and that the rlug temperaturee would be reasonably close to those expacted in any slug of "final design".

Studies are being made to determine the temperature effect of placing a high conductivity core at the center of a uranium elug. For example, a om-half inch beryllium cylinder lnight be canned in a slug; the immediate problem is to determine how much the uranium temperatures might be lowered by use of such a core.

Refinsrsnts in the ~~barummentrof the neutron deneity incident upon the "J'* and "B" slugr in a J-10 loading, with the rlqs ~o&orrping to the epeclfication for the E-10 lard, lead to a predicted cold, clean initial conver6ion ratio of 0.67 atom of tritium formed par atom of $35 depletda and k of 1.065. These valtlss are in good agreement with reported observetione on the H-10 Imdiation. The uncertainty in the predicted value is believed to be about three per cent vith much of this attributable to the uncertainty in the neutron cross sections. The cold, clean initial conversion ratio far the modlfied El-10 load, i.e., with 8.29" "J" slugs nd 3.8" "IT" slugs, is calculated to be 0.63 atom of tritium per atom of $3 3 depleted. no analysis has yet been made of the change in conversion ratio expscted during the course of the irradiation.

The cold, clean initial conversion ratio for a J-Q loading, i.e., eight inch "J" slugs and 8lx inch thorium slugs altemeted, was determined to be 0.61 atoms of U233 per atom of $35 depleted; uncertainties in this determination D ECLASS I FI ED Pile Technology Sub-Sect ion depend primarily upon bpawledge of neutron crorr section8 and uf tho rero~uance escape probability far thorim in a log pile Lattice.

OPer-all delays iP system response appear to be her than onsand ane-half periods for pile periods ranging between one and twenty arecondo. Tn the care of psriods shorter thnn one second, the delay beconmu longer'multipler of the period. The data obtained thus far in actually monitoring the rate of power increase in the test pile indicate that fluctuations due to etatistice at low laoelr mybe a troublesome factor. An exponential rate pulse generator has been fabricated to provide the simulated rapid plle power increase required to teat the system on short periods.

A "radiation telescope" to dlrect a television camera viewing high level radiation zone work has been designed and fabricated. A gray wedge pulse height analyzer has been fabricated and perfonaance tested. This tspe of gamma energy analyzer is economical and yields mfficiently quantitative results In gamma energy and relative intensity determinations for many applica- tiom in gamma spectroscopy.

The radial distribution of fission8 in irradiated Hanford slugs have been determined in several cases by the Chemistry Research Unit, using radiochemical techniques and, in nearly every case, marked asymmetries in the radial distributions have been noted. These asymmetries imply that the one side of a slug will poseese a higher heat source density, and accumulated exposure, than will the other. Nom1 radio-chemical techniques are too time consuming and coetly to permit these determinations of distributions on a significant number of slugs. A gamma scintillation detector, viewing radiation from a thin slice of a slug through a properly defined collimating Slit, is being designed in an attempt to provide the means to correlate Slug rupture or deformation with atypical distributions in either heat source or accumulated specific exposures. This is a cooperative effort with Fuel Technology and Applied Research personnel. DECLASSIFIED Pile Technology Sub-Secticm

How- ever, the rate of change and the profile cumature arerot of sufficient mapi- tude to produce operatianal difficulties. Since the per level ir currently linited by outlet mter temperature, the rining inlet water temperature has resulted in acme reduction in power level. Because the minjmum concontratian of helium ir ret in #a production test at 35 per cent, this reduction in paver level ha6 resulted in a reduction of the maximum graphite temperature to a value of lese than 450 C. Such graphite conditions could poten- tially result in pile dimtortion similar to that vhich occurred during the period from July to September of 1933. Tt war, therefore, mutually agreed With Operationr Sub-Section that the graphite temperature and helium COnditiOM under this test would be changed to conform to present Rocese Speciiicatione and that the tort would be terarinated en Boon am the pstl water speciiicationn are inswd.

Future investigation of the UBO of helimn an a meam of permitting greater heat generation in the pile moderator will have to be deferred mtil October, 1954. By thir the, there vill have been sufficient relaxation in allowable outlet temperature, available rater, and lower inlet water tompemture to permit pile operation on graphite limitr of 500 C maximum temperature and 65 per cent helium. Full Pile Burnout Expa riment - Roduction Test 10$-530-E The termination date of this production test war ret at my 1, 1954. During the initial operation under thir teat, graphite burnout rample temperatures were between 490 and 300, as desired. During the lart two months, the sample temperature6 hew varied widely and at consintently lower value as a result of changed operation and special loadings. The origixml objective of the test was to obtain burnout ilpionnation on a fU.1 pile basis at conditione of 500 maXimUm graphite temperature and 30 per cent helium. As a result of the ex- perimsntal J-Q load, these conditions are no longer attainable. Therefore, the production test has been terminated, and the graphite mining and burnout sample removal will be accomplished over the next two shutdams. A final report will be isoued sznamarizing operation under this test. Pile Distortion

Graphite Process Speciiicatiaar

Based on the operation of D Pile on Production Tort 1OS-331-E, rldficient information on the use of hslitmr ha8 been obtained to permit the further re- laxfng of this process speciiication. Bow spociiicationr have been written and are now being proce~sedto permit the me of a nmximum of 40 per cent helium at B, D, and F Pilea, and 30 per cent at CIR and E, at mcderator tempereturee between 480 and ~OCC.

Cop-CO a8 a Parrribls Pile Atmosphere

An experiment has beenchar@ into the D Pile which will partially evalunte whether a relatively emall percentage of carbon monaride in the pile atmor- phere can retard graphite burnout adallow relaxation of the graphite limit without other serious effects. Ths production test is No. 105-5354. Approx- imately 40 cc/min of a gareous mirture of 13 per cent carbon monaide, 85 per cent carbon diaxide i~ being parred over a etrillger of both unirradiated and IR'adiated graphite samplee. The experimsnt is charged in an uncooled process tube; therefore, the samples will be near ambient pile temperature. Weight change of the samples will determine rates of reaction for both irradiated and non-irradiated naterial.

Graphite Zrradiatian Dama~e as a Function of Graphite Densitz

Tnfonaatkn has been obtained on the physical expaneion under irradiation of two series of samples which have densities between approximately 1.30 and 1.85. One series of sampler vas prepared by using mixtures of a carbon black with petroleum coke as a filler material. The variation in density was obtained bs varying the per cent carbon black. The other series of samples was produced with only petroleum coke as a filler and the variation in density was obtainsd by controlling the pitch-coke ratio.

For both series, the maximum per cent expansion was obtained at a density of about 1.72, and the expmsion was significantly less at both lower and higher densities. Hw-31734

Flov Iaboratory Torte operation of tihe five in-pile tuber continued. 0136 charge of slugs from the low $E test was examined. The 8lugs had been expoeed far 57 day6 to fl 7.3 water containing two ppa dichrcmute. Retaults of the examiaation showed corrosion rates at 80 C amoxW~telyaz&ImJf a6 great as would be mcted in process water; aUo, the temperature coefficient of cmosion appears to be less at the reduced pE. Ho unwual localized cmorian was apparent. A recond charge of slugs exposed to unfiltered water at pH 7.5 and 5.0 ppm dichromate war examined. Corrosion rates were rpjgxroxiprertely the same a8 those observed in re@r process water, and no unusual localized attack occurred. An unfiltered water test was begun at pE 7.0 and 5.0 ppn dichromate. Radiochemiual analyses of the unfiltered water continued to show high mngansse activity; this activity does not appear to be a serious obstacle to the use of unfiltered water for pile cooling.

DECLASSIFIED Roduction Test8

A slug rupture occurred in tube 2679-~,ogerating under Supplement A of Production Teat 103-319-X. This tube had operated at an avemge tube power of 800 KIT and an average outlet water temperature of 99 C. The slugs had reached en ~rureof appraPtlmktely bn EaJDb. Beoatl~ethe rupttmed slug stuck in the tde, it I8 rur30ated tbat the rupture vats caused by an uranium. cleavage. "he ruptured slug I8 not yet available for examination. Alternnte slugs charged into tube 2679 had been coated with a water soluble abrasion rollstant coatlng to prevent damage to the autoclave film during charging. Damgo to the autoclave film usually results in ledge.type attack on the slugs. -mination of the coated and uncoated slugs showed significantly leer ledglq attack on the coated slugs.

Slug6 from tubes 2560-H and l88g-H showed a small amount of pitting and ledging along the rib marks. Tbmre tubes hnd operated at the higher outlet water temperature (95 C) authorized by Production Test lm-529-E.. The attack observed on the slugs was rebtively mild compared to that which had been observed on the slugs operatfng at outlet tempemsturea up to l@C at C Pile. The pitting and ledghg observed appear to be an early stage of the attack that is 801116- timbs noted at temperatures in the vicinity of 100 C.

There are now ten t-s of veighed mstpl in the piles which are scheduled for greater than 800 MWDb exposures under Production Test 105-539-E. In addition to these tubs,. five more weighed metal charges have been placed in fringe zone tubes.

Based on laboratory work with low dichromate concentrations, a production test has been written and is being approved to allow 0.5 ppdicbramate to be added to the cooling water for one-half of D Pile. Another production test to StdY the use of zirconium tubes containing aluminum slugs under present operating conditions is also circulating for apyroval. Tube Examimtion

Twelve pile process tubes were removed for examination from the pihs during April. Only 8- tubes were examined during the month. Ths foUaWiDg itOIM of interest were observed in 6amb of the six tubes: after only eleven months' operation, tube 4362-~shoved a large number of barnacles along om rib; this in spite of the fact that dichrommte was used in the water. Severe ledge corrosion and slug Junction pitting were observed in 0965-DR. The locations of eix possibly cocked slugs were found in tube 2382-c. No obvious damage occurred to the tube.

An analysis of metal hardness data which has been collected under the tube examination program was provided to Mechanical Development personnel to determine the practicability of in-pile pressure testing of process tubds. Pile Tschpology Sub-Section

An slcerrive rimer of tube failures has cawed erratic operation of the high tsnrpsraturo Minitube rpparaturr uaing uninhibited soft water. Severe erorion-corrosion of both tuba and slug has been observed at tempsratureo of 135, 155, and 175 C. A pit caused by this attack resulted in a leak in the tube at 135 C after OdLy two days' operation. Dichrommte iPhibitor will be added to the soft water mpply in an attempt to elirPinate this pitting.

Three Inch Pulse Column Studies ath Nozzle Plates - The investigation Of nozzle plates wae continued, with twenty two Purex "C"-type column and eighteen "O"-type column runs carried out during the month with "cold" uranium in a three inch limetar glass pulse column. The etudiee wre made under the approximate conditione of Purex Chemical Flowsheet HW #2. The highlights of the new findings are as follows: 1. The stainless steel nozzle plates employed in the "C"-type and "O"-ty-pe runs were of the following geometry; 9 per cent free area, 0.12 inch diameter holes with 0.04 inch nozzles (indentations) pointing down, 4 inch plate spacing. The 3 inch diameter column results indicsted that - - subdect to confirmation in full scale or nearly full scale teats - - stainless steel nozzle plates of this geametry, used in conjunction with a bottom intwface position, could satisfactorily replace the fluorothene sieve plate cartridges currently specified for the Purex Plant "C"-type and "O"-type columns. Tha pulse requirements of the 9 per cent nozzle plates are more nearly in line with those of the fluorothene plates and are within the range of the standardized Purex Plant pulse generator design (0.5 inch amplitude, frequency variable between 35 and 110 cycle/minute).

2. HC Column capacity with the 9 per cent free area nozzle plates was superior to the capacity with fluorothene plates (with 3/16 inch holes, 23 per cent free -ea, 4 inch spacing), stable operation being obtained at rates

as high as 1700 gul./(hr.)(sq.ft.), sum of flows, (equivalent to 34 tons U/day in a 34 inch diameter, i.e. Arrex Plant size, HC Column) with the nozzle plates, while only UOO @./(hr.)(sq.ft.) could be attained with the fluorothene plates. (This camparison is based on bottom interface operation in both cases.) 3- IO Column performance (vith a bottom interface position) with the 9 per cent free area nozzle plates cmpared favorably with the performance obtained with fluorothene plates 3/16 inch holes, 23 per cent free area, 4 inch spacing), optimum nozzle plate uranium transfer H.T.U. 's being about 40 per cent lower, capacity 80 per cent higher, and pulse requirements abuut the same. With the nozzle plates stable operation was abtained at a superficial throughput rate equivalent to as much as 36 tous U/day, baaed on a 34 inch diameter (Purex Plant size) IO Column (1.e. 1800 gal./ (hr.)(sq.ft.), 4ua of flmm).

4. Reduction of the nozzle plate f'ree area for the IO Column from 23 per cent to 9 per cent eliminated low pulse frequency instability. As reported in February, the IO Column wflh 23 per cent free area nozzle plates was inoperable below 8 certain critical amplitude frequency product (38 in./ min. at 500 @./(hr.)(sq.ft.), sum of flaws), due to the entire plate Section becaming filled with a ehad-roe-like emulsion and finally flooding. With 9 per cent free area nozzle plates no such difficulties vere encountered at amplitude frequency products ranging as low as 18 in./min. at 500 and lo00 gal./(hr.)(sq.ft.). Technical Manual

The elements were removed from the tank after inmersion in simulated Redox D-l2 solution for 41 days with an aversge steam pressure of 32 lb./sq.in. and 53 days with an average steam pressure of 80 lb./sq.in.

Of the four type of atainlees steel tested, 304L exhibited the best corrosion resistance. Carpenter 20 was attacked most severely while Types 309 SCb and 347 were corroded to an intermediate extent. This order of corrosion severity was obsenred on both bayonet type and process tube type heat transfer elements.

Physical testing and examination of the irradiated coupons to determine tensile strength, hardness, and flexural fatigue are planned.

Ten Unirradiated Kel-F flexural fatigue coupons fabricated from perforated plate, and currently under test, have endured 9.2 x lo7 cycles at a calculated maximum stress of 600 lb./sq.in. Six of the coupons had been notched to cen- tralize the stress. In four of these the specimen has started to crack at the notch, but to date none of the coupons has broken completely through. This

Copper Sulfide Scavengiq - ??e possibility of replacing the present permanganate head-end treatment for the ramoval of ruthenium from Redox feed solution with the CuS scavenging treatment has been reconsidered. If this treatment mre feasible for use in the Redox Plant, such a process charrge would greatly reduce the amount of ruthenium discharged to the atmosphere from the Redox stack. As presently visualized the cn9 scavenging treatment does not appear attractive f% inclusion in the plant as a head-end treatment for the following reasons :

1. Radiation instability. The Chamistry Udt found that in the presence of the high radistion fields present in first cycle Redox feed solutions the copper sulfide precipitate becanes a sticky gun uhich would be difficult to remove from head-end vessels. 2. Possibility of formation of free sulfur. Even if it were possible with additioadL research effort to produce a radiation stable CuS precipitate, the possibility of producing free sulfur exists. Processing condit?ons must be very carefully controlled to prevent oxidation of CuS and HLS to form free sulfur. If free sulfur were formed in a head-end treatment, it could conceivably cause far reaching effects in the rest of the plant. Studies would be required to dotedne whether cruds and emulsions would be encountered in the solvent extraction columns.

3. Effect on plant capacity. Calculations indicate that employment of a copper sulfide head-end treatment would reduce the head-end capacity of the Redox Plant from the presently estlmated 10.7 tons U/day to approximately 7.7 to 0.0 tons/day.

4. Hydrogen sulfide evolution. Calculations indicate that H$ would be discharged f'rom the Redox ventilation stack at a maximum concentration of approximately 900 p.p.m. Although the normal stack dilution to the ground level would be expected to reduce the %S concentration in the air around the Redox Plant below 20 p.p.m., which is considered the maximum safe concentration for an 8 hour working time limit, the presence of H2S in the stack gas would undoubtedly under some weather conditions occasionally become a nuisance, if not a real hazard.

Bismuth Phosphate First Cycle Waste ScsvenginB. At the present time T Plant first cycle wastes are being discharged to trenches in the ground. Since the possibility of contaminating ground water with the fission products in this uaste exists, trench discharge must be discontinued. A chemical flowsheet is currently being prepared based upon Chemistry Unit laboratory data for the scavenging of long lived fission products from the first cycle wastes and discharge of the scavenged supernate to cribs. Separations Technology Sub-Section

Rocess Chemistry Head-End - Iodine Behavior in the Presence of Mercury - The use of iodine tracer in synthetic dissolver solution indicates that very little iodine is retained m the MnO2 cake, either in the preeence or absence of mercury. lbission of Radio-ruthenium from Redox Stack - Labaratmy studies indicate that the mechanism by which RuO2 is formed from RuO4 in the Redox oxidizer scrubber sycrtam does not include radiation decomposition as a primary factor. Waste Tank "Bumping" - Laboratory data indicate two possible conditions which may contribute to "bumping" In the Redox aaste storage tanks: one as a re- rult of too large em excess of ?in08 (i.e., 20 to 25 per cent stoichiometric excess which, contrary to previous belief, results in essentially no precipitation of aluminum at temperatures approaching boiling), and the other typi- fied by only 3 per cent excess naOH which results in approximately 10 volume per cent 4003 0 precipitate at boiling temperature. The most aatisfac- tory conditioa? s ( .e., thoee giving the lowest "bumping" frequency in the Iaboratory) appear to be those which most closely correspond to recent plant practice - estimated curmtly at 5 to 7 per cent stoichiometric excess of NSOH since the coating rcPbval wastes are now being kept separate from the balance of the neutralized waste. From these studies it appears possible that the bumping in Tank 101-5 (at its worst about December, 1953 and January, 1954) may have been due to the well known superheating phenomenon which occurs in boiling caustic solutions rather than exclusively to the depb;.it of solids as first postulated. It is concluded that "bumping" in the Redo:: waste storage tanks whose contents are at the boiling point can be minimized by close control Of the 3aOH content which will assure a final concentration of caustic Of approxlmatcly 7 per cent in excess of the stoichiometric requirements. Self Concentration of Redox Stored Wastes - A concentration of synthetic neutralized RedQx aqueous wastes in the laboratory disclosed that the maximum concentration that may be achieved by self concentration in underground storage tanks results in a volume reduction of 3.3. This concentration to a boiling point of 144 C (at which temperature the mass solidified) vas performed in the laboratory on a waste of current Redox Plant composition, including coating removal and head-end wastes, having a neutralized sFecific gravity at 25 C of 1.323, and repreeented an excccld of 0.4 pound of 50 per cent NaOH solution per gallon of waste above stoichiometric neutrality, as determined analytically. llRAKm4 IIECOVERI! mmom Process Chemistry Two Cycle Mixer Settler Runs - A series of two cycle "Mini" mixer settler runs initiated last month has been continued to include feed solutions to the Mini consisting of various blends of current Bismuth Phosphate T-Plant waste (7-3 US) with C, B, and T Tank farm feed approximately 3.5 years old. Satis- factory fission product decontamination (ursnium product gamma activity of 300 per cent of that of aged natural uranium) appears to have barely been a- chieved in two cycles using a 50-50 blend (U basis) of current T-Plant waste DECLASSI Fi E D Separations Technology Sub-section aW-31734

(600 MWD/T) and aged metal waste as feed, while a greater margin of safety was obtained with a feed containing only 25- per cent current waste. The second cycle decont~nationvalues reported for the previous month (HW-31267) appear to be in error in predicting adequate decontdnation of 600 MUDIT material in two cycles. Evidence continues to Indicate that 200 MWD/T material can be adequately decontaminated in two cycles.

Oxalic Acid (LS Pu Pemtitioaing Ageat - The use of oxalic acid in the RAIS as the plutonium partitioning-- agent has been investigated in a series of lninia- ture-mlxer settler runs. The data indicate that &th an RAIS containing 4 M €Dl0 and 0.1 M H2C204, meeting the specification of 10 parts -/lo9 parts U- WiJ be bordeF'ine. Furthermore, when the RAIS acidity is Increased to 10 M HRO3 (still ein~loyl~oxalic wid vice ferrous ion), the plutonium content gf the uranlum product Will exceed specifications by a factor of 2 to 3. Urea Pretreatment of RAF - The effect of digesting acidified and concentrated 3.5 year old RAF wlth urea hre again been investigated. The pretreatment consisted of a 2 hour, 95 C digestion of RAF made 0.05 molar in urea. The feed solution was "cooled" and processed through a miniature mixer settler under TBP-HW #4 Flowsheet conditione. The results indicate that ruthenlum decontamination was decreased 2 to 3 fold under these conditions.

High Efficiency Pulsa Colunrn Development - Very low H T.U. values, approaching 1 inch, have been obtained previously (by the Chemistrr Unit, Applied Research Sub-Section) In 1 inch diameter pulse columns. It has now been demonstrated that similarly low H.T.U.'s are obtainable on a 3 inch diameter scale by a combination of favorable design factor (notably small perforations, low fraction of fret area, close plate spacing). H.T.U. values as low as 1.2 and 1.4 inch, respectively, at 200 and 1000 gal./(hr.)(sq.ft.), sum of flow, were determined in a 3 inch diameter pulse column with a 13 inch high sieve plate section consisting of 0.5 inch space stainless steel plates with 0.026 inch holes, 15 per cent mearea. Uranium was used as the diffusing component, under the approximate conditions of the Purex HW #2 Chemical Flowsheet HA Column, with the solvent (HAX) prescidified to 0.4 M HmO3 (to aid Initial phase dispersion), A 0.25 inch pulse amplitude was-used, at 220 cycle/mlnute. The column temperature was approximately 40 C. HOT SbMIWORKS DEXBLOPMENT

This pump, which is similar to those which have given generally satisfactory service in the Redox Plant for periods up to 1 to 2 years, and identical with those which failed after 200 to 500 hours service in the Hot Semiworks during "hot" Redox process studies, is being

DECLASS IFlED I tested to destruction under the cnnrlitlan.s of near shutoff operation employed in the Hot SamiTaPrka. Evldcnees of high bearing and Journal wear support the conclusion that failures of these 'pum~s in the Hot Semiworks were a direct result of operating large regenerative turbine type pumps at near shutoff conditione. Conversion to Purer

The design phase of the Hot Semiworks conversion (original scope) is now complete and the design of the experimental waste self concentrator Fs 18 per cent ccmplete. The conetruction phase of the conversion effort is now about 35 par cent complete. Work is proceeding in "A" Cell under time limits approaching 2 to 2 1/2 hours with working time limit6 in all other sections of the semiworks proceeding under 8 haur working time limits. lJ€uumM RECOVERY PROCESS TECBlOOLoGY c- Metal Removal

Approximately 4570 net gallons of stored waste were removed by water sluicing and direct transfer of supernatant for each ton of new uranium processed. Water sluicing increased the above volume by about 4370 gallons per ton of uranium. Ninety five per cent of the above uranium was from tanks containing saw metal aged a minimum (not average or effective) of 3.25 years, while the balance was aged at least five years. More efficient utilization of existinb facilities for uranium removal operations included the Initlation of TX super. natant blending at the UR facility per schedule, and the initially successful application of continuous water sluicing whlle incrementally balancing blend batch removals and water additions at m,. The BXR operating method initially gave dilute feeds at up to 0.35 pounds of uranium per gallon compared xith long term average values of about 0.2 pounds of uranium per gallon and, if sustained operation at these ncv high feed concentrations is experienced, capacity bottlenecks due to cross country pumping rate limitations may be minimized. A new high seven day period removal rate (149 per cent of extraction plant design) was attained during the last week of this report period using a combination of water slulclng at BX and TX (BX cont:nuous) with supplementary BX-BY, and TX supernatant blending at CR and UR, respectively, to give four "effective" tank farm facilities. The previous hlgh (145 per cent) was realized during the seven day period ending June 5, 1953, using four tank farms vlth combined water sluicing and supernatant blending. Almost no down time (2 hour electrical outage) was experienced. Feed Rerraration .

Acidification of the above feeds at the tank farms, in 2bl-W Vault, and in 221-U Building used about 13230 pounds of 100 per cent nitric acid per ton of new uranium. The nitric acid to uranium ratio was adjusted downward from an average 3.5 pounds titratable nitric acid per pound of uranium to 3.0 pounds titratable nitric acid per puduranfum on AFrll 19. The acidification Steps were followed by an average 66 volume per cent boiloff in 221-U evaporators to give feed of the followlng average composition: Separations Technology Sub-Section 4

Waste Handling

Approximately 4llO gallons of neutralized concentrated waste were returned to underground storage for each ton of new uranium processed. This salt waste included about 0.89 per cent of the new feed uranium and nlso about 3370 pounds of sodium nitrate per ton of uranium through neutralization of extra nitric acid in feed and In RAscrnb. The extra nitric acid, neutralized, contributed about 575 gallons to the above 4llO gallons per ton waste volume. The capacity of a single waste concentrator (9-1) operating to give a waste specific gravity or 1.37 to 1.40 was limiting at about 10 tom per day. Waste pH was routinely controlled at 8 to 10 with an average of 8.8. About WOgarll0r.m of low activity waste, containing an additional 0.044 per cent of new feed uranium, vere cribbed for each ton of new uranium processed. Solvent Extraction Operating Conditions

The total uranium processed by the solvent extraction batteries was 123 per cent of the naminal design input rate including 98.7 per cent virgin uranium, 0.95 per cent RCU rework, and 0.35 per cent 224-U rework uranium. Overall on-stream time efficiencies for "A" and "B" Lines were 85 and 97 per cent, respectively, giving an overall operating time efficiency of 91 per cent. Both lines were shut down (19 hours) for Condenser Vent Blower failure. Additional "A" Line down time included flushing operations (13 hours), P-19-6 (RAF) failure (55 hours), and (either line could have been shut down) waste space limitation (16 hour). Single line instantaneous processing rates ranged from 75 to per cent nominal design rate. 213 of - DECLASSIFIED Fc -10 Qpex-ations were generally carried out at TBP HW#4 flowsheet conditions using 20 volume per cent TBP in hydrocarbon diluent as organic phase and dual scrub *MColupms.

RAW losses averaged 0.2 and 0.45 per cent of the feed uranium for "A" and "B" 'lines, respectively. The corresponding losses for the preceding monthly period were 0.3 and 1.1 per cent. The greater improvement demonstrated by "13" line is attributed to use of ll0 per cent extractant flow (RAX) in this line versus 9 per cent in "A" line. The absolute differences between these two lines vary because of several differences in operating functions and mechanical difficulties.

RCW losses averaged 0.1 and 0.4 per cent for "A" and "B" lines, respectively, including operation using ambient temperature RCX on both lines during heat exchanger maintenance and an excessively high loss (17 per cent) on "B" line during test operation at L/V = 0.46 (4.0 per cent RCX, 110 per cent RAX) . Cmparable loss values for periods using RCX at 55 f 5 C were 0.03 and 0.04 per cent at L/V = 0.7 in "A" and "B" lines, respectively. An L/V of over 0.6 appears to be essential for maintenance of lees than 0.1 per cent losses to RCW using RCX at 55 f 5 C. The "B" line RCW losses did not increase at rates up to 8.5 T/D.

Gammn 0's ranged from 4.2 to 4.6 giving product RCU from 320 to 140 per cent ,of aged natur-a1 uranium gamma. The RAIS nitric acid concentration was 6 M ,and extra acid WES added to the feed to give a feed point nitric acid concentration (including acid reflux) of 0.7 to 1 M higher than that attained during the previous report period. Comparison of tEe two report periods indicates a possible Improvement of about 0.05 dF units (arithmetic factor of 1.12). This small improvement is not necessarily brought about by the increased acid,

FC-11 DECLASSIFIED Seprrrtions Technology Sub-Section BED m-3 1734 since the difference may be partially accounted for by, a) 328 average MWD/T for this period versus 348 average hfk/T for the previaua period (less Ru to uranium in feed) - factor of 1.06; b) 30 days additional "rpinp" - factor of 1.06; and c) elightly hprovud Solvent quality. During the laat quarter of the report period acid in the fed was progressively reduced to value8 closer to flowsbeet without ray perceptible change in dF not attributable to feed source.

The "A" line interface jet ha8 been restored to service.

Plutonium, matrlllc lmpur ities, and HNOq in RCU product averaged three parts per billion parts uranium, 9 parts per million parts uranium, and 0.03 pounds of nitric acid per gallon (equivalent to 0.03 M at flowsheet uranium concentrations). No change in plutonium dF was evidznt when MIS nitric acid concentration mts increaaed fraa 4 to 6 M.- Solvent Treatment

Solvent consumption for the report period was 7.3 and 1.6 gallons of diluent and TBP respectively for each ton of new uranium indicating excellent phase decanting and low entrainment losses. Continued operation of the RO Columns and ROO continuous wash tanka using three weight per cent sodium carbonate gave RAX at 1 x 10-5 pounds uranium per gallon and 17 ganrma microcuries per gallon. Eauinnent

No major equipant changes were made. Down time due to equipment failure included 19 hours for Condenser Vent Blower failure (both lines), 55 hours for "A" line RAF pump (P-19-6) replacement, and 16 hours (one line) due to P-001 UR (waste transfer) failure. URAKIUM c0IovERs10Io PROCESS TECrnOLOGY

Uranium Concentration and U03 'conversion operations were carried out at 102 per cent of neminal design rates to produce U03 including about 72 per cent TBP source and 28 per cent Redox source uranium. Metallic impurities, gamma, and plutonium in U03 product averaged 106 parts per million parts uranium, 51 per cent of aged natural uranium, and lees than five parts per billion parts of uranium, respectively. A test carload of high reactivity (1.3) powder was produced using about 0.08 weight per cent sulfamic acid as additive to the pot charges; however, process problems, including rate limitation at ca. 9.5 tons per day, pot caking, and hammer mill screen damage, were encountered. Prelim- inary observations by the customer (Carbide and Carbon Chemical Company - Paducah) indicate that reactivity increases were applicable under plant process conditions. Initial testing of one Luckey pot, resulting in production of about 1.8 per cent of the total UO3, was carried out and it is indicated that successful operation of this equipnent may be expected, although a current problem appears to be high powder entrainment to the ventilation system. Investigation of operating variables leading to optimum powder quality has been initiated. Acid recovery operations were routine, resulting in DECLASSIFIED recovery of about 1010 pounds of 100 per cent nitric acid in ca. 35 weight 1 per cent acid, per ton of urrrnium processed. The first X-3 (unloading system) orlon bag frilure occurred after 58 days in service. Uranium losses included 0.04 per cent .in copdaneate, fcmmared with 0.39 pcr cent for the previous report period, reflecting improved cyclone efficiency at higher feed to steam ratios. Nitric acid routinely sent to the tank farma contained about 5.6 pound8 of ur.nium (1.1 per cent) for each electric pot calcination uncorrected far Luckey pot operation and E-D-1 evaporator loaaea. Miscellaneow it- of rignificance to the operability and efficiency of the process included: a two fold reduction of high radiation levels by the use of appropriste stainless steel shielding which prevents the operator from "seeing" large areas of the interior pot surface8 during unloading; a plate inspection of the upper section of T-D-4 (frrctionator) which indicated expected continued satisfactory performance for the production of about 35 weight per cent nitric acid; initiation of OO3 powder recovery from filter media by wcpum cleaner; a labaratqry test qf&orlon filter bag material ahowing that dust collection efficiency fs &oat the mae as for woolbags; calculation of Luckey pot sag at only 5/16 inches with 9/16 inch additional indi- cator deflection due to expansion of measuring device (to be checked by cathatmeter meeeurementa); initlatian, 011 a trial basis, of C-2 uranium (2244 waste) blending in process streams; and planned installation of an "exDcndable" T-D-4 (fractionator) reboiler coil comprised of short sections of various stainless steel types of pipe and welding rod for obtaining corrosion data. REDOX PROCESS TECENOLOGY

3-Y The Redox Plant was shutdown from March 29 to April 7 for decontamination and repair of the,canyon crane. During the downtime, the extraction columns and H-5 Ruthenium Scrubber were flushed, and several minor maintenance items were performed in the canyon. Process performance during the month was normal with the use of a permanganate oxidation of IAF', three Uranium Cycles, and three Plutonium Cycles. Recovery of plutonium from 231 and 234-5 Building supernatant solution8 was instituted on April 15 and has been performed without process difficulties. Testing of the dual scrub 2D Column flowsheet was re- instituted toward month end, but a complete evaluation has not been made. Process Performance

Decontamination performance and waste losses have been normal throughout the month. As indicated in last month's report, increased LA Column instability was apparent after operation for ten days without centrifugation of IAF. Also, there were indications of increased entrainment of activity (primarily zirconium-niobium) into the thlrd cycles. Therefore, water and concentrated nitric acid flushes of the extraction columns (except 2n) were performed on April 3 to 5. Approximately 180 gallons of 3BP solution requlred rework through the Plutonium Cycles because of excessive zirconium-niobium contamln- ation entrained from the 3A Column interface at start-ups. One salt waste batch was reworked (discussed under Feed Preparation) without difficulty. No uranium rework was required. DECLASSIFIED Feed Preparation * The dissolver8 were charged Vith uranium having an average pile exposure of 619 (554 to 629) MUD/T. The semi-continuous acid addition technique for dissolving remained essentially unchanged. Beginning on April 23, a new schedule (outlined by Separationo Process Unit) of coating ranoval and dissolving times was imtituted in order to reduce the emleslon of mmnonium nitrate from the stack. According to this rchedule, dissolving is not performed in any dis- SOlVer during the coating removal operation (except the final. two hour digestion period) in another dia80lver. On the ideal time cycle being attempted, a dissolving rate of seven tons of uranium per day may be attained.

All IAF b8tches were oxidized by a permanganate Head-End treatment procedure using chrclnic nitrate a8 the reductant. Several modifications to the Head- End step have beenG+&e during the month in order to: a) process 231 and 234-5 Building supernatant solutions for recovery of plutonium; b) rework Redox salt wrete far recovery of plutonium and uranium; and c) reduce the emission of radio-ruthenium from-. the ventilation stack. The processing of 231 and 234-5 Building recycle solutions has been essentially adopted 8s standard procedure. The procedure for processing recycle (HW-30501) involves addition of the eolution to E-22 Recycle Addition Tank, sampling, and transfer to H-4 Oxidizer as the initial solution for make up of the IAF batch. Critical mass control procedures limit the amount of plutonium contained in E-22 T-.nk and transferred to H-4 Oxidizer. AdJustments in Plutonium Cycle flow ratios are made on the basis of the plutonium concentration of IAF in order to maintain approved concentrations in other plutonium solutions.

Rework of Redox salt waste (Batch PW-23) for recovery of 27 units of plutonium and 103 pounds of uranium was accomplished without 8 reduction in the rate of processing of fiesh dissolver solution and with a slight cost saving. The procedure used involved blending approximately 200 gallons of waste uAth 1700 gallons of diasolver solution and processing essentially as a normal Head-End batch. Thus, because theinatantandous capacity of the Head-End step is currently higher (approximately 30 per cent) than that of the columns, the Head-End equipnent could provide IAF at the maximum processing rate of the columns. The flawsheet used for processing this blended IAF through the IA Column involved only a revision of flow ratios. The normal and revised ratios are as follows:

Normal Rev1s ed

LAF:IAS:IAX = 100:115:400 IAFS:IAS:IAX = 110:105:4Oo

Since the IAS flow was reduced, this revised flowsheet actually saved approximately $40 per ton of uranium processed during the rework period. Bo deleterious effects on decantermination or recovery were noted.

Two new instruments, an H-5 Ruthenium Scrubber pump flow recorder and a monitored strip filter for stack gas sampling have been employed while making several tests to reduce the emission of radio-ruthenium from the ventilation stack. The strip filter allows collection of particles from an air sample drawn DEC LASSI F I E D Separation6 Technology Sub-section HW-31734

fr,an the twenty foot level of the stack for a yreset time (e.g., 10 minute cycle or greater), and then the particulate activity is counted and recorded. Rrom these recordings the times of the major emissions of radio-ruthenium (as particulate RuO ) from the stack have been observed to be those when the permanganate is ad ?iad to the H-4 Oxidizer, primarily the sacrificial permanganate addition- 'phu6, the following variations in addition procedure have been studied:

rate of pmmnganate addition MS decreased five-fold, and no signif lcant Improvement wae noted; OperatiOn of H-5 Ruthenium Scrubber at different temperatures and . caustic recirculation rates has shown no aignificant.effect; and establishment of lauimum water reflux in H-4 Oxidizer tower before permanganste addition is probably of considerable benefit.

Ru . 0.8 3 -9 The high iodine emission was the result of breakthrough of A-3 Silver Reactor on April 12. Since A-3 Reactor had just been regenerated on March 17, Its rapid failure is attributed to operation wlthout power to the heaters on April 7. The high ruthenium mission was coincident with the H-5 Ruthenium Sclvbber flush (1.5 per cent KMnO4-O.5 per cent NaOH followed by 15 per cent mO3-3 per cent Q02) performed on March 25 and 26. The flush was performed to remove ruthenium dioxide from the packing and pot. Uranium Extraction and Decontamination NOnlnal solution compositions of the ORNL June 1949 (acid deficient) Flowsheet were employed for the Uranium Cycles. The concentrated 2.45 M UNH flowsheets were used for the Second and Third Uranium Cycles. The 2D Coim was operated on a dual scrub floweheet for testing of this flowsheet in preparation for 3DW backcycle operation. Initial operation employed the same flowsheet as the 3D Column, but decontamination performance appeared to be a factor of three 1Q-r than for the single scrub 2D Column flowsheet. Therefore, the flow ratios were revised to improve decontamination. Although considerable improvement was noted, continued sub-normal decontamination was achieved, so the 2DA wks acidified (0.06 M HNO 3 ) in order to improve phase disengagement and reduce entrainment. The apgesance of samples of 2DU taken before and after the acidification Of 2DA indicates that phase disengagement was significantly improved by the acidification.

The Redox automatic stack gas monitor MS placed in service early in the report period. The instrument gives a continuous, quantitative record of stack gas activity, and the activity vsriations can be related directly to process operations.

The performance of TBP Plant in-line analytical instruments was generally satisfactory for operating units during the entire month. Efforts were concentrated on the development and installation of improved RAW polarograph sensing units, the installation of operating panel cycle-controllers for uranium photameters and polarographs, the installation, calibration, and testing of a newly devsl- oped uranium photometer sensing unit molded of Scotchcast, and the Installation and testing of a glass-and-8cotchcast pH sensing unit at the effluent end of the Pooled Waste Neutralizer. The plastic sensing units have been developed by Chemistry Unit personnel to reduce fabrication costs and to provide ease of installation, ruggedness, and compactness.

Inadequate continuous sampling facilities and faulty plumbing (valve and jumper leaks and jet plugging) continued to be the major causes of periodic failure or maloperation of in-line analytical instruments.

Plutonium(IV) oxalate cakes are now washed vith 2.5 of distilled vater. This procedure was adopted when data ?ram test runs indicatcd it to be satisfactory.

Equipment maintenance included the removal of the type 309 stainless steel hnace (No. 3 fbnece) and the installation of an Allegheny-Ludlum S-816 furnace. The type 309 stainless steel furnace has been retained as a spare furnace since it Arnctioned satisfactorily while in Task 111.

Canned buttom, shipped off-site, have been oxidizing and spallinu while in the plastic bags and canned. Since the customer did not weigh the residues in the plastic bags, discrepancies arose between the shippers’ and receivers’ plutonium nccounts. In order to minimize these differences, the buttons are to be observed in the R.M. Line for 24 hours before canning to prevent canning those vblch tend to oxidize at a high rate; also only buttons having a smooth surface are to be shipped. Casting (Task IV)

Construction of the Recuplex facilities in Rooms 221 and 337 of the 234-5 Building is approximately 38 per cent completed. The vessel supports for the :hree process hoods were Installed and erection of the main operating gallery t- i vas begun. Inrtallation of the transmitter hoods and duct work in the duct level hrrrr caumenced.

A study ha8 been initiated concerning the feasibility of alternately processing through the Recuplu facility low MWD material for off-site shipmcnt and hi& MWD lprterial for plutonium recovery and thus permitting, with the con- current rerctlvatlon of Taak I, the shutdown of the 231 Building. Prelimin- 8ry resultr, for uhich 0apl.ta aperating detailr have aot as yet been estab- ll8hed, indicate that alternate processing of T-Plant product solutions and the 234-5 Building waste materials from Redox solutions at production rates presently antlcip8t.d foa,.Recuplex 8tu-t-up is feaeible.

In a laboratory Imrtigatlon of variations in the Concentration Building (224-T) proceae, the-rollawlng mer-all dacontaaination factors were measured: (1) for the current groce8s (BIPOI, and Lap3 by-product precipitations and a L8F product strike), ,dD.B. - 7 and 3D.F. - 65; (2) amitting the LaF3 by- proa uct rtrik8,ND.F. * 3 and d D.E. - 30; and (3) for the procedure in No. 2, followed by a plrrtanium peroxide precipitation,/D.F. = 3 and D.F. = 9.

The Task I Rerctor VIB modiflad to Include a -;apered shaft and an air labyrinth shaft seal. The tapered sheit cqerrted setiafactorily when its rotation rate was outside the critical range (l2OO-l5OO RPM) . The air labyrinth shaft seal is effective wfi8n a slight PUCUUIU (1-4 inches of water) is maintained in the reactor.

A 98.4 per cent yield was obtained in the reduction of a plant scale batch of calcium plutanium(IV) fluoride (370 grams plutonium). The salt was precipitated from AT solution. After M attempt to dry the material in nitrogen in a production Task I1 furnace produced Q green powder, the powder was hydrofluorinated to yield a pink fluoride. It is not clear vhy drying in the line should have produced a green powder whereas laboratory experiments have produced pink podere. Investigations are continuing.

Batch, counter-current operation of Recuplex flowsheet M-1 (15 per cent TBP in CCl4; the feed made up from slag and crucible solution and SN-1 which contained oxalic acid; a reflux ratio of 24) with ten extraction, one scrub, and five stripping stages, gave the following results:

1. With 0.225 g/l plutonium in the feed (CAF'), a product (CCP) concentration of 17 g/l plutonium was obtained; aqueous and organic waste (CAW and CCW) losses were 0.22 and 0.18 per cent, respectively.

2. With 1.06 g/l plutonium in the CAF', it was necessary to decrease the L/V ratio in the extraction section from 2.57 to 2.34, to prevent excessive losses to the CAW. When the raan was interrupted while making this change and the solutions were allowed-to stand, a precipitate (probably plutonium (IV) oxalate) was formed In the feed stage and the run was stopped.

The major emphasis of the laboratory y18 in support of thorium studies and preparing for Thorex stream 8.pples. The uranium fluorometric method will not tolerate in excess of 700 micrograms of thorium in the 300 mg. sodium fluoride melt; higher thorium concentrations cause low uranium results. It has been determined that high level thorium (such as thorex feed) grossly Interferes vlth the determinations of uruumby the Chrmnus Sulfate method. This ?rote- due is carried out in a sulfate medium, however, thorium produces such a heavy precipitate that accurate titration is Impossible. Other mediums such as by hydro- chloric acid, perchlorlc acid and phosphoric acid have not proven satisfactory. Thorium determined by the colorimetric Thoron method indicates a maximum error of f 5 per cent with uranium absent. Uranyl ion causes a positive error. In- vestigations are underway to check separation of thorium and uranium by ion exchange (resin column) methods, prior to analyses by conventional procedures. By authority of A.T. Gifford of the AEC and V. D. Donihee of SF Accountability, the laboratory was relieved of the reeponsibility of maintaining a theft accountability of depleted ur~i~msamples processed to waste as a measured discard.

Radiochemical Laboratory

Beta spectrometry appears to hold considerable promise as a means of quantita- tively analyzing a solution of the mixed beta emitters, Ru-Rh-106, Ce-Pr-144, Sr-Y-90 and ~r-89-y-91. Resin samples following throughput of pile effluent water were submitted by Pile Technology for as much information as possible about the nature and amounts of activities present. Ehitters were identified and abundance estimated by using gamma and beta spectrometry, emission spectroscopy, half-life and cross sections data. A number of pure isotopes were obtained and scanned, thus enlarging the number of standard scans now on hand and placing the laboratory In a preferred position for undertaking 8 larger variety of additional work of that general nature.

\ As reported Ircrt month sane difficulty hae been encountered in the analysis of pure o4gen semples on the mas8 apectrameter.

Lattice pass iC6 The prodnctlon of 23 in Hmfurd pile8 by meam of alternating 25-Al alloy (J) and thorium metal. (Q) rlug8 or enriched natural urnalum (Ike) and thorium metal slugs -era irolll the biradmntage that the converrlon efficiency for 23 Is low. It is about 0.57 fer the cam of the J-Q ccmblnatlan arrd aOPlbWh8t lower for the Ike-Q combination, although in this latter srraagement, t&e ccaubiaed 49 and 23 conversion is high, bing aboat 0.85. The chief mason ror the low 23 conversion is that, at present Woxd lattice Spacings, these two azrangements lead to an In-pile thorium to graphite ratfo that 1s well below the optimum. One 14 thu6 led to consider loadings which allow more thorium to be inserted into the pile and thereby to obtain higher conversion efficiencies.

One such 10- ha8 been comidered in same detail. It conslats of a eolid thorium Slug with 8 fllm (2.4 mils chick) of Or6Uoy (93.4$ 25, 6.q 28) on its surface. The tubes of the pile %re load along their entire active length with these com- posite slugs. The pile now contains more than twice as much thorium as a J-& or Ike-Q pile rrnd the conversion efficiency hats risen to 0.82. The investment of 25 per unit of 23 produced bacome smaller. Cooling becomes more efficient on account of the concentration of the heat 60urcc8 ne- the cooling annulus. This type of Slug and it8 appUcations to 23 production le described in greater'detail in document EIW-31727 Preliminary values have been calculated for the multiplication constant (k) and conversion efficiency (C) of the K-pile lattice loaded with uranium oxide slug8 of density - 9.8. !Qaeee results are k= 0.97, C = 0.74. More complete calculations in progress and will be reported upon ccnnpletlon. The case of oxide enriched to the point sufficient to chain react in the IC-pile will be treated. The reactivities of lattices loaded with the 1.66" 0 .D., 1 .lo" I .D. hollow slugs have been measured. The values for the dry lattice were reported earlier but are included in the table below for convenience.

J-mG LATTICE BUCKLING Llrttice Spacing Dry Buckling 8-3/8" 907 The two sets of values listed for the 5-3/16" J-N lattice were obtained by different methods. The reason for the disagreement between these methods is not yet known. Outside the rangc of this disagreanent, hawever, is the fact that this lattice gains buckllng upon addition of cooling water. This result is at first surprising. Natural uranium lattices gain buckling with cooling water when the spacFng is less than the cross-mer spacing. However, in natural uranium lattices, this effect is ascribed to the resonance capture of neutrons in 28, an effect which is very small by comparison in 25. In this 25 lattice, the increase in buckling of the wet lattice is due not to the resonance capture effect, but to the rather large decrease of SloWing-down length which takes place on addition of water to the lattice. This is, in other words, the rather rare case in which the decrease ink is more than bslanced bs- the decrease in neutron slowing-down length, thus leading to a higher buckling. It is seen, then, that it is possible to design safe lattices even in the case in which resonance capture is negligible. The buckling of rtaadard slugs in the 3-3/8" 1 ttice was measured in a 4' x 4l x 4l exponentid pile. %e reat is 119 * 2 x 10-8 an-2. me buckling of this lattice (from meammments in an 8' x 8' x 8' pile) is 118 x cm'2. The agreement between the two valuer 8 that measurements in 4l x 4' x 4' piles are correct to within a taw unit6 ot 13Ym-2.

The magnitude of the neutron flux at same point in a medium is ususlly measured by Imerting a neutron absorb- foil at that point and mbequently counting the resultant activity. This rrctivity la proportional to the neutron flux impinging on the foil. Bet- the neutron flux is changed by the presence of the foil, the question rurlser 88 to the relative rize of the changes in the flux induced by a foil in media of dificrant absorbing characteristics. In order to answer this question, the following calculation ha,a been m: the flux perturbation haa been computed for a foil placed in a graphite medium and for a foil on the boundary between graphite and uranium media.' It waa found that the perturbation differs by less than 0.1 percent in these two cases showing that the effect discussed is negligible in most experimental work. This result is reported in more detail in document HW-31482.

Irradiation Effects on Uranlwn Four preformed tenmile specimen6 ubich were irradiated at a temperature of 150 - 175 C to an average axpotsum af 310 W/AT (4.5 per cent U-235 burnup) were tested by standard mathode in the Radianetdlurgy Laboratory. Tn, of the specimens were tested in the an-Irradiated condition and two were vacuum annealed at 400 C for 15 hours pr:.or to testing. The as-irradiated tensile data showed the material to be brittle and that the yield strength increased by a factor of more than two. The ductility, as measured by per cent elongation, was drastically decreased by a factor of fifty after exposure in a Wordprocess tube to 4.5 per cent U-235 burnap. Th& testing of the irradiated-annealed tensile specimen revealed very little recovery of the ductility of the uranium when canpared with the unirradiated tensile data, suggesting that structural damage is small in comparison with the "foreQn atcsp" effect cued fission products. All of the temsile specimens exhibited the typical sqyare fracture of a brittle material. It waa also found that the ultlmate strength of the irradiated metal was lower than that of the unirradiated uranium.

The rod of the fourth specimen, a straight rod inteoded to operate at a calculated maximum temperature of 550 C, appeared to bave warped against the side of the annulus. Further rsdiometallurglcal exaadnation of these specimens and longer irradiations of simile specimtas are plaPaed. he1 Element Studies

Three u9niunr-mSgncsium fie1 elements using uranium in the form of small cylindrical paichings have been fabricated and machined to standard four-inch slug size.' These are currently being teated by the Experimental Physics group. Closer exaJnination of other uranium-magnesium compacts showed ody about 50 per cent wetting of the uranium surface. A magnesium-1.4 weight per cent silicon alloy wad substituted for pure magnesium and complete wetting of the uranium surface was observed snd a bond of considerably better strength was formed. This sample appem to hsve better corrosion resistance to boiling water than the uraxlum impi;ignated with pure magnesium.

The four enriched cored slugs charged in the hot spot in C-Pile in February under PT-105-513-SI are still operating nomally, having now accumulsted an exposure equivalent to about 600 MWD/T. Plans for a supplement to the production test to increase irradiation time to lo00 MWD/AT have been changed to continue the irrad- Fation until a ruptun occurs in the tube. Since the tube contains 20 normal eight-inch solid slugs, rupture could occur either in the normal solid slugs or in the cored enriched slugs.

Cored slugs are currently being investigated in the hope of producing a fbel element having si&ficantly reduced thermal stress failure probabili-ty. It appears possible that a further gain might be made by introducing an insulating layer between the slug and jacket to increase the average uranium temperature during irradiation. This increased temperature of operation may act to anneal out part of the radiation damage effects which cause dimensional instability and/or reduced ductility. Initial investigation is directed toward producing a cored slug, jacketed in aluminum with a layer of anodized aluminum adjacent to , .,

the uranium. Stwersl can6 have been anodized on the inside with a 4-5 mil layer of "Martin Hard Coat". The anodizing conditions of 15 per cent %SQ+electrolyte, 5 amps/sq.it., and low temperature produce a dense, black, adherent coating which appeara to be quite uniform radially but to increase in thickness toward the tap of the can. ThLs variation can probably be avoided by better control of electrolyte temperature.

A survey of physical, mechm'lcal, and chdcal properties of uranium dioxide has been ma$e and Is being prepared in rough drait form in connection with a feasibility study Oi,&hls lEatePial for fie1 element fabrication. Operation of a 1.36-inch diameter solid uranium dioxide fie1 element at but 30 kw/ft would suffice to melt the core. In fact, tha &de wauld break up at a much lower specific power; the circumferential themal atreas would exceed the ultimate strength of the material above 2.5 kw/ft. Awre favorable fuel element from a opacffic power standpoint involver UOg pUotr of near theoreticsl density in a metrix of aluminum, magnesium, or eirconiun. Thlr oaaa la baing inmatigated further. A simple method is desired for fabricating uraalum oxib-containing hrel elements of.varioua designa to permit reactivity and amemion ratio meaeurcments. Tamping ' powdered UO~,m3, or u308 ever unacceptably low denritiee of 4.5, 3.0, an8 3.6 m/d, renpectiveu, and sintering facilities m not aveilable on site for producing high density uranlum oxide. Accordiagly, a mock uranium dioxide haa been proposed &.ir being p-bfor 305 Pile test, coxmisting of a pressed mixture of umnlum metal chip6 and a material such aa M@ or B-3 to prqvide oxygen duplicating the neutron scattering effect of oggen in U02. It has been suggested that a machined notch in a slug would serve ae a stress raiser whom effect vould be calculable and which would induce split-type rupture8 mproducibly and more quickly than would uncharacterizable, naturaUy-occurring dtfecte in metal. If this is true, then other aspects of metal quality could be studled by me of notched rptuimens. Accordingly, two uranium specimens wlth longitudinal V-notches of standard Izod gecmatry were run in the induction cycling apparatus in cooperation with Fuel Technology personnel. Cracks developed In the notches after a much analler number of cycles than has been the experience of Fuel Technology personnel with material contsining naturally-occurring defects such aa striations. Consequently, notched specimens are being prepared for irradiation in the MllR and notched ccllppanion pieces prepared from the same rod will be subjected to induction cycling.

A variational method has been uaed to derive fonmilae for calculating thermal stresses in an externally cooled hrel element as a function of outer diameter and core diameter, specific power and coolant temperature. These fonrmlae have been evaluated for 1.36-inch outer diameter fael elements operating at 50 kw/ft in 105 C outlet pile coolant temperature. The maximum circumferential tensile stress of a solid fie1 element is 43,800 psi; on curing, this maximum stress is reduced by 19, 26, and 40 per cent for increasing core diameters of 0.272, 0.544, and 0.816-inch, respectively. Detailed results of this analysis wlth formulae for Mercalculations vi11 be published shortly as HW-31681. Applied Research Sub-Section

Determination of k as a fnnction of temperature over the range 500-600 C has given an approximate activation energy for this growth procerrs of 38 kilocalorierr/Prdle and, hence, permits extrapolation to the lower temperstures of contemplated operation. Such extrapolation predicts a 0.1 per cant growth in eight months at C and 0.1 per cent growth in three years at 350 C; ~lsopredicted arc a one per cent growth in three years at 400 C and a one per cent grovth in 15 years at 350 C, provided the same mechanism of . growth in air amlies at these lower temperatures. Zirconium specimsae fmsn the rods as vse used in an in-pile test wherein washers of zirconium were exposed at an estimated lo00 hours at 450 C (HW 3U.U) have been vacuum annealed 250 hours at 450 C. The hardness change produced by this treatment is similar to the hardness change observed in the irradiated specimens whereas extrapolation fram the scanty Information available in the literature suggested such annealing would have produced dead-soft material. Wrcaloy-2 specimens that were annealed along vith the zirconium showed an increase in hardness which can be attributed to a precipitation hardeaing effect.

MllR me1 Element Testing Facility

Ewzhents with the mockup of the MPR test facility have been completed by Pile Technology Sub-section. The apparatus is now being disassembled for shipment to ArCo. Slx A-blocks have been fabricated and are ready for loading. Two shipping D ECLASSI FI E D 1

crates for A-blocks hape been constructed. The machining of fuel element specimens for the first three experiments is almost ccnnplete. Carmlng of the specimens will begin shortly. Three A-blocks will be charged with specimens and shipped to Arc0 dnring May. As a resalt of dircussioars with the Kl!R policy board in Chicago, it ha8 been decided to utillzC position A& in the MllR reflector for the firet experiment rather than A-39. The estimated power generation in the latter is 100 kw/ft whereas in tba former it is astinratad to be 75 ~nr/ft. ~n attempt is being made to detmaxparimentally tht. flU% depm88iOn to ba aCountcrCd in thh A-block in the MPR refleator in order to be able to batter ertlmate power generation from maps of the unperturbed thermal neutron flux in the MPB. An A-block, charged with specimens and with flux monitora distributad throughout the as8aplbly, YZLB irradiated in the 305 Pile, and mrbsequently the activity of the monitors datennined. Activity values were obtsinud for 55 locatione b the A-bloak. The unperturbed flux in the 305 Pile will be mearurtd when pile time ir mailable. When this is done, the flux depre8sion be determined. Ram the data obtained 80 far it can be said that (a) end effect8 due to using only a one-foot charge are leas than if a longer column of epecime~were to be uaed, and (b) no radial -try of thermal neutron flux &e to the euspmwtry of the A-block WLLB detected.

Radicnaetallurgical Examination A metallurgical exambution of the Ike slug iroln PT-532-A3 which had been irradiated at a pover lmel calculated to heat the center of the slug above the alpha-beta transformation temperature of 660 C w~8begun. R*axuwerse and longitudinal sections were cut and electrolytically etched in a 10 per cent .solution of Hn03. Macro- examination of these samples revealed that there were no voids. However, meroua small cracks were ueen along the central axle of the rlug and an etch pattern showed a po8sible alpha-beta transformation are13 approximately 3/4-inch in diemeter. Metallographic examination6 of these cracks and of the possible phase change areas are now in progress.

One Ike slug was ernmined fram PT-532-A-2 that provided local boiling of the water at the end cap of an enriched slug which had been canned with a thin cap. An indent In the can vall which ran the i'ull length of the slug ggve a "worm" track appearance- A transverse semple of the slug revealed that a fine crack existed in the uranium beneath the indent in the can wa3l. The crack extended into the uranium along a radius for about 1/2". No gross inclusions or any other evidence of abnormal metal quality could be seen. Metallographic examinations of the can wall and the crack are now in progress. The examination of rupture #283 fmm a production test to evsluate the rods rolled at Fernald waa completed. A OrZLok 3" long and 1/10'' deep WSB obsemed to eAst in the plane of the iractura and evidently existed at the time of canning. A report is h prOgra8S

Twr, rlugrr which had been fractumd by the &el Emmdnation Sub-Unit were received for erpadnrrtion. One aug, *ah iractured at a ten-ton load, was fram a production test to apalusts the lead dip canning of heat treated slugs, PT-W. The fractured Suzzace waa very unlfora~and was rimilar to that of a Xrornral, unirradiated slug. 91he second rlug YLLB a 8tmAIl.B triple-dipped slug vhich fractured when a three-ton load wae applied. !Chis rlug had a very -men fracture surface. These fracture patterns &we to be correlated with metalloehic studies to attempt to explain the difference in bresking strengths.

Redicmnetallurgy Facilitie8 and Bquipent The new cut-off box vas &uecesrfuUy wed in obtsining emples from irradlated material. After cut- a number of 6pecimen8, waste disposal and the abrasive cut-off wheel dum&g operati- were succss~acccmplished. We cut-off wheel WSB first decontaminated to 5 Rad/hr at 4" before disposal by cutting through a bar of steal.

The metallographic cell vas successhrlly used to prepare samples for x-ray diffraction rrtudies. The oolvent dcgreaeer v~llremcnred and the electrolytic polishing unit will be removed for alterations. Radicxtive liquid waste disposal plerns were reviewed and when aspirators bec- available most solutions will be discarded via the crib waste dispoeal,~te!m. T!he aqueous insoluble oil now being used as a grinding vehicle is not anenable to the crib system and will have to be collected for separate disposal.

Equipment is llov being fabricated to speed up the examination of ruptured fuel elements. A system 8indlar to the one used for disposal of contaminated waste in the cut-off box will be modified for slug examination cell operation. The filter within the cell is now contamlnated to 26 R/hr at 1" and 280 Rad/& at 1" or 3 R/hr at 3" according to recent film studies.

A ncutm anneali Auaace, capable of temperatures to 900 C and a vacuum of gpproxirnately mu, wa8 inetalled in Cell D along vith electrolytic cleaning apparatus.

The tensile tester wss shielded, air flow control and tensile grips for shouldered specimens provided, and manipulation accomplished to provide pertinent stress- strain data for 1/4" AslM standard epecimena of irradiated uranium without undue radiation or contamination occurring.

Modification of the cathodic etching equipment reached the point where non- irradiated samples of uranium were tested. !The cathode is to be placed in a junior cave for f'urbher experimentation.

Equipment for making carbon ana lyse^ and hardness tests is being collected and cold runs will be made shortly. Macro etching, equipnent is being fabricated.

2 i rp23 Applied Research Sub-section D ECLASSI FIE D Separation Plant Cornsion Problems Several allaye are being rtudied to determzipe their corrosion resistance in Redox mte concentrator solutions Stainless steels type 3&L, 30-, 347, and Carpenfer allay #20 were mcpo8td for three month8 a6 heat traMfer units in a scale-up test in tha F-4 vessel in the 32l Bxllding. me 304L wars to have mffared the least aorrorion of those Uoym, but the corrosion spparrsed excessive in aU cams.

Welded acraplcs of type 75-A titanium m be- cxpored in a laboratory sltedwaste solution to detedne if welded titadtun is corrosion resistant in thls solution.

several specinks from one heat (apprwtely 25 tone) of type 304~etainless steel hebeen examined in the laboratory to evdluate the severity of a condition Vfiich led to firaurlng during shearing and/or chipping operatiom at a fabricator's plant. The he& of 6Wess rtsd involved had been rolled to l/2" plate and a amall amount to lpplate, iraa four, ingots cast frcm the heat. Each of the four 1-t~ waa cut ipto iuur sJ.aIm prior to ro~ing,making a total of 16 lots of plate fran the heat. It had been determined normal inspaction procedures that aJl the plates involved =re ratinfactorlly resistant to interpanular corrosion, and that it met aUthe required charaical and physical properties requirements. However, two lots, which upon 8hearbg ahowed cracks dong the sheared edges, were replaced by the 8upplier. AB more of the plate wss ued in fabficstion, necessitating shearing and chipphg operations, the cracking became so widespread that an investigation vas begun. This Investigation disclosed that the phenomenon was conftned to one heat, #RO-9164, and affected in more or leas degree a.ll of the plate in the 16 lots made from this heat. Twu lots were examined in detail, including microscopic and macroscopic examinations of the structure and, in the case of one lot, accelerated corrosion tests to determine the effect of draatic corrosive conditions on the defects. The conclusion was reached that the cracking was caused by widespread laminnr non-mtallic inclusions oriented parallel vith the plate surfaces. The effect wa8 wide8pread but varied in reverity from one lot to another and within the 8- lot Hone of the material vaa considered of high enough quality for the SepeSe semlce encountered in concentratore. Accelerated corrosion ksts on three Spec*- frorm one lot apparently reflected fairly accurately the variation from one location to another within the same plate. One specimen exhibited virtually no attack on inclusions, another moderate effect on inclusions, and a third, severe attack at fissures caused by inclusions. Plutonium Metal Fabrication

Eqerinrent8J. nitriding of hardened high speed tool steel used for machining plutonfum wa8 accomplished durlng the month. Tools presently used to generate plutonium shapes must be discarded when slightly worn because of the close dimensional tolerances specified for the flnished product. nitriding of high speed tool steel is a method successful in same applications for reducing wear. The present experiments will eealuate the method with reapect to plutonium machining. A six mil nitrided layer wa8 produced by heating the steel in an ammonia atmosphere at 525 C for 24 hours On stress relieved steel, dimensional changes resulting from the treatment were negligible. A modest increase in tool life will easily pay for the nitriding treatment and more importantly will simplify production machining operations. " Stress rupture tests of welded 309SCb stainless steel to evaluate its performance iE simulated reduction banb service we under way. Test results thus far indicate that welds can be mad@!on 309scb stsi~lesesteel that are satisfactory for high temperature serrrice . Metallographic examlnatian of elactralytically polished and etched plutonium indicates that this muthod of specimen preparation doer not produce satisfactory or consistent results . Eqyi-t ir therefore be- arrsembled to test the feasibility of cathodic vacuum etching of plutonium. 'phn abrence of any electrolyte in this method is con- ducive to bproved &lineation of dissimilar phasea. Concurrently, an in-hood metallographic microscope is being installed to pennit specimen examination directly af'ter polishing and etching. With the present -nt it is necessary to seal the specimen in a spacial viawing container before metallographic examination. The apparent crystallite aizes of PuOe powders heated to different temperatures have bean determined by x-ray diifraction line broadening measurements. A sample heated at 270 C had an appaxent crystnlte siqe of 30 8. mles heated at higher temper- a-8 had increasingly lergcr crystallite sizes. A 6-1 heated to 600 C, the Itighest temperature tested, had a crystdlite size of 300 6i. . One sample heated to 600 C was off -color, be- black in contrast to the reddish brown of the other samples. his off-color sample h~da partide size of 90 W. These particle size measurements are of interest in studies of the chemical reactivity of the powders. A method for coating plutonium by diffusion of nickel from solution in a liquid nickel-magnesium-calcium alloy is being evaluated using uranium as a stand-in for plutonium. Metallographic examination of the best diffusion soats of nickel on uranium which have been prepared to date has shown the presenze of many voids and inclusions. The method appears to be of little value at this stage of development.

CHEMISTRY

Two countercurrent solvent extraction m.u.u were carried out under Purex IA conditions to evaluate decontamination obtained at an elevated operating temperature. The conditions consisted in 12 extraction and 7 scrub Mini stages, 3O$ TBP, and 20$ Hanford fission product level. At 50 C the ganmra DF was improved five-fold over that obtained at 25 C, this including a 12-fold improvement in ruthenium DF. In a Mini run involving 19 Mini stages, the Purex 1Bu was subjected to scrubbing; at 50 C the gemms DF obtained in scrubbing was tvo-fold greater than at 25 C, this involving an eight-fold difference in mthenium decontamination.

A review of the Purex analytical requirements shows that existing Redox and Metal Recovery methods are applicable and available in all cases but three. A method for detenaining nitrite in IA and 2B feeds has been developed and transferred to the Control Laboratory; a procedure for determining alpha total in organic streams has been established; and a coulometric procedure for determining high concentrations Of nitric acid in uranium and plutonium streams is under investigation.

DECLASSIFIED -ThOkX Previous reports discussed investigation8 of thorium metd dissolving. Similar work YBS carried out duriq the month with thorium oxid@ and showed that in a mixture of boiling 60$ nitric acid-O.OO5 M hydrofluoric acid (optimum conditions), the Us'- 601ving rate is 1/10 of that o6kipad with the metal under optlnrum condltions. Increased or decreeused fluoride concentration retarded the rate of disrrolution.

A flame photometric and a polarographic method for determining low concentrations of uranium Me been develuped. Slmllarly, a caabined versene titration technique ha6 been established for determining both thorium ad aluminum with high sensitivity in -rex streams. A revlay of the andytical methods that appesr to be necessary for Tho- research and development show that 14 separate methods are established end that eight othera are #till receiving attention. Wrtonium-Uranium Alloy Mssolution

'phe iwestigation of methods for avoiding the potential explosion hazard in the dissolving of zirconium-Jacketed slugs ha6 proceeded in three directions. Confirm- lng the observation made at other sites, it ua8 found that 0-Zr alloy is completely desensitized by fluoride-containin8 solutions. It wa~further observed that heat treatment of the alloy at 800 C, and subeequent qyenching, sold8 a Burface that is not eubject to explosion. The third approach is directed at (,he establishment of the rate of formation and the rate.& deetruction of the sensitive material as a function of nitric acid concentration and time, the purpose being to establish aptimum conditions for minimizing the hazard. An equation showing the rate of desensitization has been estauishd.

In assistance to me shove zirconium investigation, a titration technique for accurately dete-ng small Quantities of zirconium has been established. Ruthenium Studies

Effort during the month ha0 been directed to application of previously developed chromatographic techniques to Redox solutions in an attempt to identify the eldating forms of ruthenium. On the basis of the very limited number of teats, it -pears that the head-end treatment exerts a marked effect in reducing the orgamic-soluble ruthenium species. Separate tests showed that both the anionic form and the hexone soluble form are almost completely destroyed by such treatment. mer, it was ahown that eolld ruthenium -- either precipitated or adsorbed -- wars in appreciable quantities. In two samples of dissolver- solution, solid ruthenium extsted to the extent of about le, and in a third sample it was found that newly all the gama activity was associated with a precipitate. Approxi- mately half the ruthenium in HIK> appears to be in the solid form and the bulk of the ruthenium in 1CU appears to be as the solid. It appears that the head-end step is beneficial in controlling ruthenium and should be retained and, further, that greater attention needs be directed towards clarification of the HIMD.

Applied Resesrc?b Sub-Section effort is being directed toward8 -1s of a large mber of process samples and towards the study of a dlchrcmate treatment that may control the ruthenium and minimize tetroxide formation.

The introduction of SO2 during between-cycle UmEt boildown of synthetic Purex eolution resulted in a ten-fold Improvement in ruthenium decontamination in rub6equant extraction8 .

Mervork mbstantiated the previous report that flash calcination of UBH is beneficial in producing a U03 prodnct of hi& chadcal reactivity. A series of TJHE saqples of varying 8iZe were calcinad at 250 C on a laboratory hot plate. A amd2 sample that uaderwhnt calcination In 25 minutes yielded a product having a reactivity of 1.56, and a large sample requiring 3-l/2 hour8 for. calcination produced U03 of 1.13 reactivity. A nearly line- relationship udets. betveen reactivity and calcination time. Annealing a hlgh reactivity 6earple at 300 C had a very minor affect. It waa shbm that both the heat of hydration and the heat of n~tralizationof uO3 are dlrectly related to the chemical reactivity. In neitper caee, hawwer, ir the meamrement of heat of reaction sufficiently sensitive to constitute a ragid reactivity test.

Waste ’freatment

Scavenging treatments yere carrled out with atored first cycle Bigmuth Phosphate waste mrpernate. Acldlfication of the earnple to pH 8.5 and treatment wlth ?ickel ferrocyaalde effected a cesium decontamination of 1200 and yielded a soluticn well belw cribbing levels. If subsequent tests with fresh first-cycle wastes yield similar results, Separations Technology plans to reccrmmend routine treatment and cribbing of the 300,000 gallons of waste produced monthly in the T Plant.

Shllar tester camled aut vlth Metal Recovery stored waste supernates showed that cesium deconteminationepf 1000-fold a.re readily obtainable and, consequently, that it is feasible to treat and crib such wastes. Pile Problems

During pile irradiation of uranium, Pu-240 Is produced by two paths, mely, the Cagt’care of neutrons by Pu-240, and secondly, the capture of neutrons by lQ-239 and the subsequent beta decay of l?p-240. If the capture cross-section of I?p-239 IS large, the second path may be appreciable in the presence of a hlgh neutron flux and may limit the pile power in the production of low g/t plutonium. Since this capture cross-section is very poorly known, a procedure has been devised for its determination. A sample of uranium of very low U-235 content Kill be irradiated. lap-239 Kill be recovered from the eample and re-irradiated under controlled conditions to produce Hp-240. A radiochemical determination of the latter Will then allow calculation of the desired cro8s-section. The experbent 1s being conducted jointly wlth the Physics Unit, and preparations are under way to allow the conduct of the analyses in the pile area.

Fd-15 Tvo chemical crperstione were caxried out in assistance to the Physics Unit. These involved detexmlnation of cobalt in a neutron monitoring specimen and separation of daughters from a sample of thorium.

prevlouar report8 have referred to v&aua aepects of the extensive program for establishing in-line -era in the Hot Semi-works. In mmaay, this program includes ll tot& PIIIIIII(P mnitora, each of which ala0 be employed for determining the gemm 6pectrum; one plutonium gama photometer for dctermjning high concentrations; five uranium photometer6 for detellmining high concentrations; two uranium polamgraph8 for detealow concentrations; two turbidity detectors to evaluate the extent of dispersion; two pH monitors, one for the vaste neutralization and one for the organic cleanup scrub; and one "alpha printer" for determining plutonium in wsete. The latter instrument w88 developed by the Chemistry Unit and is be$- designed and constntcted by the Instrument Unit.

The overall in-line installation mqbe conaidered in terms of three component igwupinga. The first conrists of three master program switches, each of which controls the seqwnce of a group of analyses. The design concept of these units is complete and shop drawings 8z-e being prepared. The second grouping includes eight operating panels end the associaM micalrecorders. The panels execute the individual steps of one or more analyses, these steps conaisting variously of jetting sample degassing, activation of monitor and recorder, discharge of sample, reset, etc. Units henre been deaigned in detail and shop drawings are 60$ complete.

The third grouping consists of the individual sensing elements. Design and shop drawings of the ganrma monitor are complete and construction of the prototype unit is 23$ complete. The associated gamma spectrcnneter is constructed and on hand for later installation. The source and detector cell of the plutonium gama photometer have been constructed and mockup tests are under way. One compact disposable uranium photometer cell has been constructed and placed in service in the Metal Recovery Process. The unit has operated satisfactorily and the design judged suitable for use in the Hot Semi-works. A simple control power source that works Off the ll0-volt lipe hm been developed to replace the battery source. A compact disposable uranium polarograph cell has been constructed and placed in service in the Metal Recovery Process. However, f'urther attention is being given to the design an attempt to min.lm.lze iron interference and reduce mechanical difficulties. Design of the turbidity unit is 50$ complete. A suitable pH cell has been constructed and placed in service in the Metal Recovery Process. In-line results agree to 2 0.3 pH units with the laboratory results and samples for the latter have been discontinued.

Separate reports were issued during the month presenting the data and specifications for P-10 Phase One and Phase Two analytical equipment. Anal~lcalDeveloment

Analytical problems receiving attention during the month include selection of a sample bomb and analytical methods to allow analysis of gases formed in the high temperature -pressure pile "loop"; establishment of a direct mount radiocounting procedure for determining plutonium in Recuplex organic streams; and development Of a s-lified procedure for determining Am-Cm in process samples. The Hanford designed x-w photometer hsrr been evduated for various analytical applications and found highly satisfactory and has then been made available to the General Analytical Laboratory for service. Off-site tests involving impurity anslyses of uranium oxide and grsphite with the echelle grating spectrograph have been evaluated. It is concluded that some! increase in the sensitivity of rare earth determinations is obtained and that impurity determfnstions may bet made more rapidly in sane cases, since no prior chdcal separation ia reqylred. The mer- benefits, however, are relatively minor and do not agpear to bear further attention at this time. The previous report referred to the idantiiicstion of hydrogen in non-bond areas of canned slugs. Further work ha0 shown this observation to be an error and that the hydrogen observed vaa apparently formed from reaction of sdsorped moisture on the surface with freshly expored slumimrm. mertests in which this effect was eliminated indicate the absence of .any gaa in the small non-bond areas. Large blisters formed in slugs processed through the hot press procedure contained essentially pure nitrogen. I)econtamination and Waste DispoclaL

One million gallons of "retention" level ktefrwn the Works Laboratory Area were processed to @mu%.Forty thousand gallons of "crib" level waste were transported to 200-W for disporsl to "crib"; mince an increme in activlty approaching 200-W crib limits v~lsnoted, it will be necessary to concrete a greater percentage of this vaste in the future. Two "cut-oii" boxes from Building 327 that required special hadllng were diacaxded via the Technical burial ground. Disposal of polishing oil from the Lap Master Slug poli~hesin the RadiometaUurgy Building presents a special p~blam,and consideration is being given to use of a special cask that opens from the bottom.

Thfdy two man-haure were spent doing special decontamination work in cubicle room 1F, Wzildfng 222-6. A lO-foot gloved box in Room 96, 3706 Building, was completely sealed and safetied in accordance with the recmndations of R.S.M.U. and the wrflding and Grounds Engineer, Technical. Removal of two four-foot gloved boxes 3706 In the near future wlll cauplete the neutralization and limitation of potential hazards in areas formerly occupied by the Chemistry Unit in 3706 Building. Laundry selepice for Building 3741, hot graphite shop, was assumed. All other laundry and building service Mctiontr were accamplished in a routine mamer.

All Applied Research Sub-Section personnel engaged in work that might reasonably be expected to result in inventions or discoveries advise that, to the best of their knowledge and belief, no inventions or discoveries were made in the course of their work during April except as listed below. Such persons further advise that, for the period therein covered by this report, notebook records, if any, kept in the course of their work have been examined for possible inventions or discbveries .

slug c& chazm8&ties To obtain the uu&Imum information about the resistance to rupture of uranium slug cores by thermal cycling in the electrical induction unit (woodsplitter), it is necessary to establish the relationship between power input and the slug core temperature. Preliminary results of cycling tests indicate the power necessary to cycle the slug cores from mom temperature into the beta phase is between 55 and 65 KW/four;inch piece or 165 :1% =/foot; This will be confirmed with slugs containing thermocouples; These data will be med to plot cumes showing slug core temperatures at given power input. -- Because of the incidence of obaemed slug warpge in recently discharged irradiated uranium slugs, an intensive program to determine the causes of this -age has been initiated. Facet8 to be invtsti@ated are orientation, the uneven heat transfer during irradiation a8 related to control rod configuration, poison column location, and non- unifOrrPity of slug poeitioaing in the tubes. In addition, preliminary studies on the distribution of fission products in selected warped and unwarped irradiated slugs from the stme process tube will be made with special shielded equipment as 80me mal- distribution has been reported by Kinderman of Applied Research in what was assumed to be Uaiiormly irradiated material-.

Reductic& and.Caat& -

Apparenxly the Mallinckrodt and Fernald plants could increase their production capacities significantly by faster feeding through the fluorination step in the process without af'fecting the quality of uranlum metal produced. Results of metallurgical tests on uranium slugs from selected high snd low oxygen green salt parent material indicate that the metal from the high oxygen material is equivalent in quality to normally produced uranium/ 2 1 1; 2 3 4 Fuel Technology Sub-8ection m-31734

Be investigation of oboe& rolling deformation petterns and their relationship to in-pile longitudinal failures ha8 been pursued by testing uranium slugs in the "woodsplittdl . -- .- Reaults of testing boa 88-rollad .nd bats bat treated uranlm slu@ in the "woodsplitter" show that 22 slugm, of 26 tested, failed in the previously marked node area8 which were located ultraeonically.- It ha6 been established by marked rod section8 received from Femald that the ultrasonic node peaks Ue directly beneath the inZtial roll to metal contact poiate. Although beta heat treating appears to eliminate the ultrasonic pattern, the longitudinal failures persist in occurring in the node areas which were marked before heat treatment. Further testa me being made to determine the cause of these obaerved relationahips with the expectation that the knowledge will iadicate ways of avoiding or decreasing some of the veaknesses in ruture 8llg corea.

Four ruptures at E Pile and one mpture at C occurmd in FT-19-M (Irradiation of Triple Dip Canned Uranium frm Rod6 Rolled at Fernald) during the cmntrepoxing period ~e~8~~~~,~9~Gdm/T. Of the four ruptures at H Pile, two are belleved to be jacket fallurea, one s core failure, and one was not clsssiiied. The rupture at C pile has not been examined. Qupture rates of Fernald and Simonds rolled material show no significant difference t the same exposures.

Cold Finishing to Slug Mameter Cold finItshinP processes are being investigated becsuse of the promise of considerable savings that could be effected by cold sizing rather than machining ursnium rod to slug diameter. me material cold dram at various cross-sectional reductions at Bridgeport 811 reported in laat P#Lith'a Technicsl Activities Report, should arrive on site by mld-May. Anothcr cold finishing pocea~,"~nlskanning'~, has been used at HAP0 to effect croaa-sectional arc8 reductions of approximately 15 per cent. Slugs machined from both as-rolled, sad rolled and beta heat eeated rods have been experimentally "unisksnnedft to yield satisfactory surfaces. ''Uniskannlng" 1.405 inch diameter rolled rod to sltq diameter will be attempted in the near future. Heat Treatment of Uranium Nineteen control tubes in PT-744 (Irradiation --of Alpha Canned Uranium ---Slugs from Rods ---Salt Bath Beta Heat Weated at Fernald) have been discharged at various irradiation exposures since*- zr-53. !Be one control tube remaining in pile is currently at 1104 MWD/T. About 300 supplementary tubes chsrged in this test have been discharged at approximately 600 WIT. There has been, to date, only two ruptured pieces out of a total of 13,700 pieces charged. One of these ruptures, a four-inch slug, in U84-~,discharged September, 1953 at 414 MWD/T, appears to be a jacket failure. The other rupture, an eight-inch slug in 1087-0 was discharged at '3-93 MWD/T in April, 1954. This rupture has not been classified because of its complex pesrance.

Lead Dip Canning of Beta Dated Ifiaaium Cores

An anou&Louts weld bead cUtion in lead dip canned slugs wc13 recently observed. The "defect" is an AlSi spike usually about 20 mils in diameter (essentially AlSi of higher silicon content than the surrounding mew in the fusion zone) that starts at the base of the fusion zone and pierces the bead, terminating at the exterior of the weld. About the time the splkes were detected, it- observed that the lead content of the baths did not level off em in production test canning but continued to rise. In general, the faraation af spiksu end the associated anodic can xall areas seem to be favored by higher than normal lead concentrations in the canning baths. The occur- rence of these spikes, huwever, haa been very rpmuodlc and unpredictable to date, the number observed gar tmck varylne ~Ldelythroughout the day. More data are being collected to clarify the situatlm tmd the use of Fillemelding a8 a corrective measure is being evaluated concurrantly,

Examination of the irradiated production test lead-dipped 81- has not disclosed significant amounts of weld bead attack, although an unexplained "ring" at the cap- core junction was observed on most of the slugs examined. Examination of these irradiated pieces is planned in conjunction with the one available cap from the three recent cap failure8 in lead-dipped canned slugs (P.T. 313-105-25-M). No relation between the abnormal weld bead conditions noted in lead dip fabrication at this time and the susceptibflity of eight-tnch lead dipped slugs to jacket failure is apparent. Hollow Uranium Slug Fabrication

A satiefactory welding technique was developed for fusion welding uranium wafers in the ends of hollow uranium slugs. The slugs produced are suitable for jacketing, and standard canning methods umy be used for initial evalustion of externally cooled only hollow slugs to reduce the magnitude of the thermal stresses inherent in solid slug cores under irradiation.

Agproximately 70 four-inch nickel-plated uranium sings were hot-press canned for bonding and C- studies. The results were aln@ularly -ked by blister forumtion. It vas belimed that the source-. of &arr Lnadeqaate air removal during sizing. Three subsequent testa,

'ndicated that this waa the case. Apparently the uranium under the porous nickel coat- .gS (non-heat treated) "getters" the entrapped air. When the nicl.el coat is heat treated, the "getbring" pmr is reduced by lateral diffusion of the nickel across the pores. Work is continuing in an effort to eliminate air entrapment, Several hollow slues were hot-press canned under varioua conditions to establish the feasibility of the procesr. The elwcanned satii3factoriI.y with no gross deformation of the hole appsrent upon sectioning.

Hot-press canning of the "J" metal shipmcnt of 391 extruded slugs was. completed. Of this number, 217 were aocepted for pile (56 per cent yield). Blistering C.Bing the cengoperation was reduced from 37 per cent in the previous operation (with cat cores) to 8 per cent with the extruded cores. Poor bonds as detected by the ultrasonic bond test increased from 7 per cent to 19 per cent. Work is continuing in an effort to develop a more convenient method of surface preparation of the components than the bruahing with abrasive that vill give equally consistent good dtffusion bonds. Thermal Hot-Press Canning

Nineteen four-inch and three eight-inch nickel coated uranium slugs were canned by the thermal hot-press method. Lack of blistering and the results of various non-destructive and destructive tests Indicate a consistently satisfactory fuel element, One hundred eluw are being canned by this process for a complete out-of-pile evaluation.

Vacuum Canning

.nty-six nickel plated four-inch slugs have been canned by the vacuum process for possible irradiation In the MTR. An additional two hundred are to be canned for Hanford irradiation.

Approx~tely30 per cent of the lugs from two control tubes of the Production Test 25-M designed to iurther avrrlucrte lead-dip canning were found to be warpt=d to as much as approximately 50 mils. No difficulty w88 exparienced, however, during the discharge of the metal from these tubes. In addition, practically all of these slugs in these two tubes contained a well defined line around the periphery of the jacket at a point adjacent to the cap - uranium Junction. The cause of this line is being investigated.

Testing of the contour projector was completed. This device will project the image of the edges of irradiated aluge with SOX magnification onto a translucent screen and thus give maaeurements of diameter, warp and distortion. Installation of this equipment into the 105-B facility was in progress at month's end.

Eddy Current Instruments

New probes designed for light weight and fast response to surface irregularities have been built for the AlSi penetration equipment. The existing MIZ-1 equipment is being modified to use these probes. An intensive effort is being made to assemble this equipment together with a simpler, cheaper, and more rugged conveyor into an instrument for use in slug manufacturing lines. It is planned to be ready early in May for separating slugs to be irradiated to high exposure levels. Also the MIZ-2 instrument DECLASSlFlED DECLASS 1 F I ED Fuel Technology Sub-Section Hw -31734

It must be understood that both of these models are prototypes and not fully engineered production type inst3pmcnts. New model8 of both inotruments are aesigncd, most of the parts have amived, and shop constrtlctlon will begin next month. Mechanical Comyors The continued sesrch for a cheap conveyor, -d enough to withstand heavy use and eaay to nuintain has produced a radically different desi-. !The conveyor consists simply of two driven rolls with their -e8 slightly skewed.

The Flow Cup Laboratory tests at temperatures under 100 C are continuing. The equipment for extending these tasts to 150 is almost ready. The data ere being correlated with the polarization studies to &termins whether or not.@vanlc studies of aluminum corrosion are of any -tical value, at least ea far as the study of corrosion of aluminum in the pile irr concerned.

The first two discharges of the pieces from Production Test 105-29-M have shown that for low exposures, thermogalvanic corrosion ia of little or no importance. The maximum exposure was approximately 200 MWD, and the maximum temperature was ap- proximstely 70 C.

Some eight-inch slug cans on heat treatment developed large pains, many penetrating the can wall. This may lead to serioue corrosion problem. FuFther teats we being conducted to de*rmine the extent of intergramlar or diiferential corrosion.

Tests have shm that in the autoclaving procedure used by Manufacturing, dilution of the tap water by condensed steam results in water of high quality. The film on the autoclaved pieces is comparable to that obtained by autoclaving in distilled water. The results of a production test will determine the relative merits of the films obtained by different procedures.

New types of anodized films have shown increased resistance to hot water. Exposures -* elevated temperatures to pile water and deionized water have shown that these ma afford protection even after 30 days' exposure. In practically all cases, these anodized pieces suffered leas corrosion than the control samples. In addition, the anodized films gave complete protection against mechanical damage during charging. -7 -- -c.

RDS-p-13 Mechanical Desiaa Develoment Hot operation and develomt of the pmtotype &el elmemt canning machine continued through the month. Major Podiffcation of ths turret which handles the can and sleeve assemblies in the bath ad &e cap feeding mechanism resulted in an arrangement which adat8S the problem of bath material freezing on these devices and interfexdng uLth operation. This mdiflca~on,coupled with an increased preheating time, allowed caps to be successf"ully assembled in the can without slugs deng the latter part of the month. A signFfycant devdopnmt connected with this modifjcation is the success- f'ul use of "Transitem (asbeatos Fibers bonded with Portland cement) in the can- bath for static parts subject to abrasion. A program for the developnent and fabrication of a prototype in-line alpha monitor was started during the mmth. The proposed developaant installation in the Hot Semiworks should field adequate operational data on low fission product lines. Schedaes were established for all phases of the pmqam thFaagh the prototype installation in the Hot Semimrks. The mecharrical detsil digwings of the monitor have been caupleted and a recpisition for its fablcrcation is ready for issue.

Study of the technical aspects of radio frequemcy heating was continued for appucation to the problem of weldinc; Fpel elements, reqaiz5ng the accumulation of understanding and working knowledge of high frequency high power vacuum tube oscillators, in addition to the rather special addof eddy current heating and welding. RDS-D-U, Utilities and Services Desim DeveloFanent Work cont;Fnued during the mnth on the acquisitim of all possible information on buried lines, both thmugh exadnation of maintenance records and currently exposed pipe sections,and the data indicate that corrosicln is greatly accelerated in areas where the earth is heated. In addition, it appears that bituminous coatings of the asphalt variety tend to deteriorate after long exposure to heated soil. All drawings and arrangenents for installation of a pipe coverlng testing facility as part of the corrosion study were completed.

RDS-D-15 Ens?.neelinn Standards and Materials Develoment Cost to date for developaent of en@neering standards for the current fiscal year is $40,062.

It was decided to coordinate the efforts of Projects CA-53.3-A and CG-558 in suPPl& raw water to the separatiana areas fmn the reactor areas. As a result, procur-t costs and duplication of constructiar effort dll be mized. Other artd~cosfvra angthe mnth concerned the investigation of a "dirtyn heat of stainless steel which is baing wed in the fabllcation of hex concentrators and silver reactor heaters. The tolerances for the cooling annulus between tube inserts and finned process tubes used in the condensers of the Furex dissolvers were established, The problm of eruption8 in the Redox waste tank farms have been studied and alterna- tives of handlhg W plpblema in the Pur= mant were developed. It was decided that it is economically advantqeoas, now that additional capacity is needed, to take a loss on the cancellation of surface condenser faduties and turn to the use of the contact type.

The Manager, Public Relations attended a GE public relations meeting in New York City on April 22 and 23 and the Atomic Energy Commission Industrial Information Committee meeting in Columbus, Ohio, on April 27 and 28. One of the many significant results of these two meetings was the impression gathered that both G. E. Public Relatians people in New York, snd AEC Industrial Information people in Washington, D.C. think HMO's public relations activities axe developing in the direction they consider most desirable for the best interests of both organizations.

Articles submitted to trade publlcations during the month were: "Maintenance Of Reactor Auxiliaries and by C. B. Wagner, FACTORY MAGEMENT AND MAIITENANCE: "Operation's Barometer by Difference Analysis," by Fred W. Richardson, MILL AND FACTORY; and "Mechanical Agitators for Heat Treating," by C. E. Frantz, PRODUCT ENGINEEZING.

It also was agreed that we will send a pictorial article based on the Radiochemistry Laboratory to ANALYllICAL L!€EMISTRY magazine for their new feature, "The Laboratory of the Month," and R. T. Jaske is preparing an article on heat conversion at Hanford for HEATING AND VENTILATING.

The flrst package of the Construction Progress motion picture footage was delivered to the Contractor, Telefilm, Inc. this month. This was a test shipment and part of the more than 27,000 feet of exposed, undeveloped film footage taken on this Broject. Six employees of the studio have been "cleared" by the AEC which, because they are technicians, provides us with the advantages of having film developed and workprinted on the same basis as was prevtously done at the San Francisco studio. Good results have been notM from a special questionnaire devlsed to determine the effectivenesa of the film "Herers Hanford.'! Orientation audiences 81'e asked to complete carefully worked out question blanks on subjects contained in the film. The results not only lndicate that the film is eervtng Its Fn- tended purpose but, also, that it 1s highly entertaining and lnformativc.

A second print of the film "Here's Hanford" was processed and sent to us by the processing studlo in San Francisco. The studio, feeling we were not en- tirely satisfied with the first print, made up a replacement at their own expense.

With twenty-five new tedmicrrl- gmduatete hired against an euthorizatim of forty, additional respansee are caing very slowly. Accordingly, we have conducted a number of follow-up dimere rt the follovlng nrjor ~chools,jointly with Schenectady representatives to encourrga scceptanceo- from the -‘we #pt, and to get our quota.

In a separate report we are listing a rrubstantial number of present Word technical personnel who might be affectcct by Selective Bervice poUcy; this report will also autline what can be done recrdting-wise if additional recruiting should be authorized to meet expected losses.

Our search for PhD candidates principally in metallurgy, engineering, and physics, is intended to phuce between fifteen and twenty hires divided between additions snd replacements. Although this vork is proceeding very slowly (only three acceptances to date) we expect to substantially meetfithe needs in the most critical fields of metallurgy and physics. Needs for erperienced engineers have declined but we are trying to keep in touch with a few active carndidates, recognizing that the situation could cha,nge quickly. Recruit- ing visits have been made in Califoda and in Denver at sites where subsantial numbers of personnel are being released due to cancelJ.ation8 of other projects. Ehgineers interviewed at these sites are being considered for actual and potentiail needs through- . out the Atomic Products Division, including ElApL and Alop as well as Hanford.

ROTATIOHAL mGPROGRAM

The Rotational mining Prog~amstill has forty-one members, the same as a month ago. During April three permenent placements vere made and three former technical. lpgduates returned from military sexvice. Organizational changes have delayed additional placement which vere contemplated. On the other hand, needs of the AlQp Department at Idaho E’alls are increasing and can be used as placements for some of our trainees if necessary.

Medical examinationa decreased from 1,050 to 988 while dispensarg treatments increased f'rom 4,801 to 5,289. The health topic was "Stress and Strain*. Sickness absenteeism was 1.66% as compared with 1.73% for March while total absenteeism was 2&% as compared with 2.4l.% far March. Safety and Fire Prevention No major injuries were repcrted. The total to date remains at three as compared to six for the comparable period in 1953. There were three sub-major injuries and 389 minor injuries while the number of all injuries to date is 1,236 as compared to 1,332 for the comparable period last year. Luck wauld seem to be a factor in our lower major injury rate to date. There have been 65 days without a lost time injury and this represents an excess of three million man-hours and should qualify H.A.P.O. for its sixth'"Award of Honor" from the National Safety Council.

Kadlec Hospital Consideration has been given to the proposed legislation for hospital disposal and recommendation made to change undesirable feakres. Budgetary requests for appropriations to make hospital additions and changes considered advisable before Hospital Disposal were not approved by the A.E.C. locally. The average daily census increased from 78.0 to 89.2 as compared to 101.7 a year ago. The occupancy percentage of the mixed services was 87.0.

Wsafety and Fire Prevention just transferred to the Medical and Safety Unit. The net cost of operating the Health & Safety Section before charges were assessed to various departmenti WBS $93,509, about $23,000 more than February and som $7,000 above the budgtt. Some of the increase was due to assuming the cost of the Safety and Fire Prevention Program. The remaining difference was largely due to the increased salary costs due to three additional days in March. While net costs for the first nine months are $19,000 or 3% less than the budget figure so it seem reasonable to assume that the total section costs will not exceed the budget. However, it seem probable that Kadlec Hospital will overrun the budget by about $15,000 due to revenue being less than estimated.

A lawsuit was filed in Superior Court of the State of Wasvington on April 13 against General Electric and the Head of Industrial Medical Semces claiming damages in the sum of $83,590 for not Informing an employee of questionably abnormal findings on a chest x-ray made during routine medical examination on April 20, 1949 and August 8, 1950. The Health Activities Comnittee met on April 15 and the topic on "Stress and Strain" was presented. The subject deals with methods of combating daily Stresses and strains in living. Haterial on this subject was prepared for distribution throughout the plant. The sickness absenteeism was 1.66% as compared to 1.73% for March.

Net costs incurred during March totalled $36,27&, an increase of nearly $3,000 or 9% from the previous month. The increase in salaries was the principal contributing factor and was attributable to there being three additional days in March. Also included in March costs were moving expenses incurred through bringing one industsial physician to Richland. Seraices rendered to the Atomic &ergy Commission during the month were approfimately $2, '90 greater than in Febmary, thereby offsetting partially the increases in gross costs.

Gf-10 Public I3eal':h Unit AMher decllne in the incidence of communicable diseases reported was noted, due chiefly to the lower incidence of measles in the codty. We ham reached the point where there are fewer sasceptible individuals in the commnnity and themfore the apidendc uill be ending. Total derof cases to date is 1260. Other diseases reported of significance are whooping cough and chickenpox. In the former instance, immanizationa are being stresaed in an attempt to stop the spread of this disease which can be prevented by imnuniwrtion. The Public Health nur8ing hams vlsit leva1 remained about the same with emphasis being shifted to infant care rather than communicable disease. Morbidity and child hygiene visits remained at about the same level.

A Crippled Children's and Handicapped Children's Clinic was held with Dr. C, Don Platner in attendance.

During April, the Social Service counselors had 138 interviews with parents who were concerned about their relationships with their children, Help in solving marital problems uas sought in 72 instances. There were 60 interviews in which children under 13 were helped with behavior and attitude problems and 54 in &ich similar material was discussed with adolescents. Thirtg interviews were held vlth adults concerned with irdividtual ad3ustment problems . Thirteen families were assisted dth health and economic problems. Twenty sanitary inspections were made in food handling establlshments. All were found to be operating satisfactorily. Flies are beginning to become prevalent in a few restaurants, due to improper handling of garbage.

Inspection of 34 dairy farms resulted in two being degraded because of continued insanitary practices. Bacteriological results of pasteurized milk and cream samples were well within state standards. Samples of milk from bulk dispensers in restaulants were tested and proved satisfactory.

Sterilization of water mains in new transportation terminal was supervised by this section. Bacteriological samples proved negative far coliform bacteria,

Coliform counts of effluent fkom sewage disposal plant continued to be higher , than desired. However, additional samples were obtained of effluent before it enters Yakim River, and these were well within State standards. They were also less than counts obtained f'rom the Yakima River. Eight dog bites were investigated for possible rabies. All proved to be negative. Six nuisances were abated involving does and other animals.

A catch basin and trap connected to sanitary sewer was installed at Benham and Armstead to eliminate water pond- at this location. Approximately 3000 cubic yards of 3/4" minus and 400 cubic yards of 1/2" chips have been crushed and stock-piled south of the By-Pass.

A secund pumping test was made at the Richland ne11 field during the first two reeks of &mil to.determine the effects, if any, of the Wary Pool on the underground water storage at this field. Wells 2, 4, 5, 12, 13, and 14, were pumped over the two week period without benefit of eurfaoe rechiuging, and it was necessary to progressively cut back the pm$ing rate due to continuous draw dmof the water table. The amount of draw down verified the results of a previous test that there is no indication of replenishment of this underground storage from HcNary Pool. Wells 3000 - E, F, H, J, K, and L, wwre again surged and test pumped. To date these wells have developed to only 50% of installed pump capacity.

The automatic roto converters for control of chlorine feed to the 3000 area well headers were installed on April 15. Adjustment and minor alterations were made by the manufacturer’s agent and the converters are nor in service.

The rpecial study groop on vehicle contamhation obtained a satiefactory solution to the inmediate problem. Particles presumed to arire from nuclear detonationa were wide-rpread throughout the Pacific Horthwe8-t.

In research and devclupment, two findings on tritium vere of interest; one VM a meaaurcMnt of transmisrian of the active material through phatic sheets; the other canfirmed in wethe early finding in rat6 that trf#um once bormd in the organiw tends to enter metabolic pools of relatively slov turnover rate.

Ground water teste in the Gable Mountain region indicated very high local permeability and the probability of significant ground water movement toward Hanford.

General

"here were 21 lnfd, 5 Class I and one Claer I1 dation incidents. The Clasr I1 lncidcst Endlcated a body expome of 10.5 roentgens, the highest on record at the Works. However, there appeared to be nothing in the work schedule of the affected employee that could have cawed each an urpomre. Dillgent investigation of probable aberra- tione and of a conaiderable'number of highly inrprobable ones failed to resolve this discrepancy.

The special ntpdy granp on vehicle contamination perfarmed an excellent piece of work in ~~istingothers to establish an adequate decontamination faciUtJr, and in themaelves doing enough experimental work to determine that the Inhalation hazard from particles redistributed from vchicle surface8 is low caprrw.red with the conventionally accepted direct risk in the separations we-.

A fourweek6 training course in radiological sciences for a gropp of department personnel and invltees from the Maxcufacturing Department was conducted. Group lunches were held with relatively new employees of the drpsrtment to promote better wrhrsl understanding. It is proposed to extend the scope of this contact method to employees of longer standing .

A new procedure for off-rite disaster monitoring wa8 prepared at the request of the AEC. This procedure rbollshes permanent team and sub- stitutes a random call system.

Significant ground contamination at the site of the proposed physical Constants Test Reactor was noted.

Studies were completed OD posaible radiological effects of a msjor disaster of the proposed Phpical Conatants Test Reactor.

Investigation of the high river water design basis with respect to reactor effluent disposal indicated that reduction of the design basis from that of the 1894 flood level to allow same bank discharge under occasional high water conditions would produce no significant savings on proposed additional disposal facilities.

Ground water tests at the proposed Gable Mountain reactor effluent disposal area continued to indicate very high local permeability and the possibility of significant ground water movement probably toward Hanford. The possibility of Sidhr ground water movement betveen Gable Mountain and the 200 Areas plateau Is suggested. Reconrmendations for additional studies are in preparation.

I - 17 summary The flrtrt pbme of our property management program has been completed Kith the inventory of all unlmtalled equipment in the plant. Tha next phase of this program it3 to reconcile discrepancies between the inventory jut completed and old plant record8; to rtaaWdlze descriptive data on equipmant; and to furnish the Property Control Unit8 with permaaent record cards vfilch vill enable nranage- ment to plan etrrre replacemnt program. When the Raparty Control Unit program is completed, it 6hdd insure cment and accurate property records, positive plant-vide custodial control of federal property, and information to management as to the equipacnt on hand. Depreciation expense amounted to $5,935,0UO in April, an Increase of $1,201,000 campared with laat month, resulting principlly from increased separation of uranium. A special study of plant and equipment and depreciation accounting was undertaken during the month; the results axe expected to be reported in two phases.

1. Revlew of eemlce lives of 100 Area facilities and recommended depreciation changes, if my.

2. Depreciation, classification, capitalization and obsolescence of

I all facilities at, Hanf'ord.

The annual physical inventory of essential materials (excluding coal) in the c*atody of the Manufsctming Departmen* was taken a8 of April 30, 1954.

During +de mon-55 of April, a substantial portion of the total effort was directed toward establishing the Appropriations Unit as a substitute for the Appropriations and Budget Committee, which was discontinued My 1, 1954. Organization and Policy Guide (05.1) describing the new procedures for plant and equipment appropriations was issued.

Property Management Unit

WOproperty management practices governing the control of sensitive types of property, that is, property which lends itself more readily to theft, loss, or personal use due to its attractive nature, have been given special scrutiny. The Conmission is especially interested in the controls of these types of items and hss expressed their satisfaction with the steps taken by the Company in this control program.

The Manufacturing Ikpartment is now preparing a project proposal for the consolidation of the 100 Areas machine shops. This brings to a close one phase of a property management machine tool utilization project, the objective of which was to secure, insofar as practicable, the consolidation of our machine shops and better overall utilization of our machine tools.

Principles and methods employed by chemical and utility cees, requirements of AEC, policy employed at General Electric installations, and the specific requirements of HAP0 are being examined in the study. The transfer of one exempt employee from Internal Audit to Plant Accounting during April increased total personnel to 35, comprising six exempt and 29 non-exempt . Inventory Accounting Unit Prior to the +&in& of the annual physical inventory of essmtial materials (excluding coal) in the custody of the Bnufacturing Department, surveys were made of all storage locations and meetings and conferences were held with custodial personnel in order to formulate procedures, establish time schedules and procure the manpower for taking the physical inventory.

Preparatory work was started in making the arrangements for taking physical inventories of electrical materials in the custody of the Electrical Distribution and Telephone Section and of excess materials and equipment in the custody of the Stores Unit. These inventories are scheduled to be taken respectively on May 20 and June 2. In conjunction with the physical inventory of electrical materials, arrangements are being made to reclassify and transfer those materials currently booked in spare parts inventory to general supplies inventory.

Proccdurts have been vritten and bo& wired for the autamstic recoFdlng, &yeis, aad reporting of padlit guuge dab irom sll areas. In vim of the . recent izmtallstion of many &rwges which may be sdjusted without Interfering with normal resctor operation, it mu dadadvisable to maintain a ament record of the gauge statu6 of every tube in every reactor. It is expected that ud- ~uStme3lt6of there &Uuges vill be msde frequently at3 part of the standard mer- ating procedure for raising power level and reducing pumping pressures; hence an accurate and ecommlcal neap8 of noting those changes is desirable. !&is can be aceqlished quite adequately by maintaining a punched card file and issuing reports routinely to qperating personnel. The first attqt to obtain a correlation between slug nzptve rate and exposure und power in C-reactor was uneucceasful. Following a meeting with representatives of the Process Imprwumnt Group, a new method was devised. It is hoped that this metdod wiU yield more conclueive results.

A rsmpling plan is be* set up in which the distribution of the coal in a fire box will be studied for various operating methods of supplying coal to the furnaces. One iurnace will be ahut dawn, and eampling within the furnace will be used to determine the coal distribution for various rates of supplying the coal to the Aupace by the stoker and ditferent sizes of coal particles. If a method for supplying coal to the furnaces can be determined to obtain better efficiency, considerabli~ savl13@3 could result due to the large amunt8 of coal consumed at Baaford.

A set of tables was prepared for use with an instrument designed to measure the specific gravity of a liqpid. A drop of this liqyid is allowed to fall through another liquid of known density, and the time of descent measured. These tables eve apeciric gravity as a function of time of descent for seven different experimental arrangements, and *re calculated by solving a -tic eqyation on the card-prograzumed-calculator.

The further analysis of attitude surrey data for the Reactor Section has been completed. Attitudes of employees in the various personnel classes within each subsection uere analyzed separately. In addition, the attitudes of the same classification of employees in sepsrste areas within esch of the three main sub-sections were compared statistically and a summary of all written cements was prepared. (Report: "Attitude Sunrey Results -- Reactor Section", to J. H. Warren.) For the Manufacturing Department 3 routine IBM reports knd 19 non-mutine jobs were campleted for a total of 22 IBM semice requests. Considerable progress was made this month in the fabrication and assembly of the Redox Model being constructed for the Separations Section. The architectural portions of the silo, canyon and service facilities ere approximately 95s c0m- plete. Final assembly of the building- walls and general frame work is scheduled for completion the first week of May. Fabrication of operating equipment, tanka,

These d;rsvlngs primarily cover canning processes showing mechanical compsrieons between the old and new methods, production inareama and coat savings. Additional grsphics serpices colducted for the Manufacturing Department included posting currant data to and lesucurce of the Manufacturing Control ems;preparation of a chart titled "Amrsge Percent 'Rrmover 1949-1953"; and completion of misceUaneous budget and cost charts.

The relationship between the distance between atomic planes in mute and the anout of exposure of the graphite is to be estimated from experimental data. The formulas required for estimation of the relationship, confidence intelvals about the estimated line, and tee* of hypotheses for weighted regression were submitted. (Oral report and outline: %bple Linear Weighted Regression for the Case of Weights mown Without Error", to J. R. Towneend.) !The report covering the @ity of thc metal produced at both the Feed Materials Production Center and the Mallinckrodt Chemical Works was delayed due to more pressing matters. !be study will be concluded early in Msg. At the request of the Advanced Technology Sub-Section, calculations relating to design of a wsrm-canning press were carried out. Weinstrument consists e~sentiallyof a coil of wire through which a current is mssed, and inside which the slug to be bond@ le clamped in place by two end pieces. The problem is to determine the spacing of the coils so as to insure a uniform temperature Over the surface of the slug, and at the sans tims atah a phyeically realizable flow of heat into the end pieces. Several different arbitrary temperature distributions (in effect, coil-space dicltributiom) were studied in an attempt to find one with desirable &at-flw charactefistics. ple original fornulation of the problem broke down when a divergent aedes was encountered. A second fonrmlation gsve better results, and one pattern was obtained vith the desired pruperties. A good deal of effort WM spent in making these results avialable in time to set design specifications for this instmment.

Several slugs which failed under irradiation had their aluminum jackets stripped Off and the billet numbers were obtained from the ends of the bare slugs. All available information on the chemical dyaes and density of the heats from which these billets came was provided the Uranium Quality group of the Pile Fuels Sub- Section. It is hoped that these data would shed some new light on the cause of slug failures.

For the purpose of f'urther investigation into the causes of slug failure during lrrsdiatlon, a study was made of boron analyses of uranium metal cast at Mallin- ckrodt Chemical Works during the months of January, February, March, and April 1953. Percentages of the total number of boron analyses within certain ranges or

-Je-5- c groupings were determined. These percentages were compared with those of the heats iram which ruptures are known to have conb?. (Verbal report to the Uranium Quality Group of the Pile Fuel8 Sub-section.) Aa a result of a reaent meting with the Process Control and Analysis Group, the (sraup lfine Matal Sbdy trill undergo a mor revision. Plie study was initiated over two yeus ago in all effort8 to find obsentdble cause8 of slug-rupture. Metal charged iato the pilea wa8 -ahasifled into groups, snd cxposura and power data on there -6 calculated routinsly. It was necessary for statistical pqpolrea to make parer ccrllculatlom on aU tuber in a until the last tube in that group had been discharged. The prerent revision cnlls for claseifylng metal by Wordlot number, in the hope of correlating mturtd-slug data with lot vsriables LL~well M pawr and axposure. Reports to be issued include ex- posarc distrlbutione by reactor by lot, for both active tubes and tubes Us- aged since the praVious report; gowar distributions for all active tubes; and an exposure distribution forecast for all active tubes. All tubes in all areas WLll be included in this rtudy.

Considersble data ha+ been collected OB rupture rates of variouo slug types and ~lumcrou~coaapa,rlso~ have been atkmpted to determine the best type of slug. Uslzq only production results, a lsrge amount of information would be required to precirely estimate the mmU percentage associated with rupture rates. Due to the many factors meeting rtlpture rates and the fluctuating aperating conditions, it has been difficult to obtain mfflcient informstion under comparable conditions to sccuratel51. compare rupture rate8 of varloua slug types. A test procedure has been devised which will gr~?stlyreducs the amount of dsta required and will result in objectivedecisions conc.tming the better of two slug types being compared. A thoraugh atatistical Investigation of the variation expected indicated that a test based on the average difference in the MWD/t at rupture with as few as two tubes of each type of material has a good chance of discriminsting between the two materials. Definite probabilistic statements indicating if eignificant differences exist between rupture rates of the materials congared were tabulated. Since a very few tubes wlll be required for each test, a flexible program of testing materials at the same time in sajacent mer in order to wrpose the material under BFmilar condltlons vill be possible. Al80, due to the small size of the test, a large number of tests under different operating condition8 can be effectively carried aut. (Letters to L. W. ~ang, 4ril 16 and Mril 28, 1954.)

Additional work was done 011 the c&kulation of expected frequencies of excessive temperatures caused by local power eurges in the piles. The Original work was completed in August, 1953, and the additional work involved calculating expected frequencies for a different set of fundmental assumptions. (Verbal report: April 2, 1954 to 9. S. Jones.)

Additional. CongutatioMl work was performed in connection with the pressure and water quality relation in a reactor process tube. New constsnts were used in an attempt t0 reconcile the continuing discrepancy between calculated and observed values. It 1s not presently known whether these discrepancies m due to experi- IUentEd error or to an incorrect fornation of the problem. A decision on how to proceed with the problem is waiting on -her study of two-phase flow and verification of the present formulation.

I -le of data,- the, single column data reduction experiment in C-reactor has been received. These data are punched in-paper me at the pile by an automatic recorder, and consist of periodic readings of some ten vhables associated with the particular tube. Work is proceeding on the development of a procedure for transcribing ths data from the tspe to cards, decoding the data, and calculating the necessary informertion. Since all the data are coded, it will be neces88ry to convert the coded informstion t0 mQanlllgnPful numbers before an anaJysis uau be made. Two methods for doing this are under consideration; one method la to perform a ca3.d table look-up operation on the coded data, the other to cdaulate the desired quantity by means of an empiricsl curve fitted to the coded data. Which method is wed will depend largely on the ease with which the method msy be modified in the event that the recording instruments are recalibrated. Starting in May, data vlll be received and processed daily. This study is the most refined attempt to date at estimsting the precision of the present methods for computing exposure and at suggesting improved methods for this camputation. It is urpected that a large amount of statistical aaslysis wlll be made on the data. llhe first qet of data on tubes with J-Q 10- (alternate enriched uranium and thorium slugs) in E-reactor b~ebeen received. data co~istsof tqerature and pressure reading8 iKrm 36 tuber,, of which 13 actually car~ythe special load- lng. From these data it will be possible to calculate individudl tube powers and urpoeuns in much the stme meras the aaalysis of the hot spot in C-reactor is being carried aut. Tenq?erature msps on these tubes will be recorded daily, -4 processed m0nW.y along via pressure .and power level data. llhe study will ;We for some six months, during whidi time the results will be used to analyze the all-important yteld characteristics of the new type of loading.

One method of eetlmsting the corrosion rate for the mxximum corroded slug in a given tube consists tn analyzing the influent and effluent water for alum content. It is known that this method of estimation is not too accurate, and hence, when comparing cornsion rates in two tubes, this measurement error nut be considered. A discussion was held with a member of Pile Coolant Studies on the statistical aspects of this problem. (Verbal report: 4ril 7, 1954, to Don deHalas.) Work had been done some time ago on the relationship between corrosion rate and Slug surface temperature for water Qpe 10. The report issued at that time indicated that a similar relationship was thought to exist for water type k, but insuf?fiCitnt data was available to test the validity of this. Recently, enough dsts has accumulated to establish this relationship for fixed slug power. Further, bz1 estimate of the corrosion rate aa a -&ion of slug power slug surface temperature was found. (Secret Rough Draft: Pgril 16, 1954, "Corrosion Rate vs. T8," to S. Goldsmith.)

A functional relationship was estimated relating slug corrosion rate to flm rate for various tube parers. An equstion qressing the corrosion rate directly 88 a function of flow rate and tube power was also found. This proved to be a fdrly good fit for the range of values of tube powers of greatestpractical 'ntemst, but the resultlIq equation was not vdid for higher tube power levels. pointed out that by fitting a polynomial of high enough degree, a relationship could be found that would hold for higher power levels too, but it was decided -.. that the first eqpation would suffice. !be purpose of this whole study was to set safe operating limits for the piles from the viewpoint of determining what limits could be reached before the smut of corrosion expected would exceed a given tolerable limit. (Secret Rough Draft: &ril 29, 1954, "Cornsion Rate VI. FlOVhb", t0 8. GOlwth.)

It ia known that numy factors, acme hi- corralated, affect the comosion rate of a slug, but no -licit relationship has been found to date expressing the corrosios rate M a function of mare than one or two of these pertinent variables. Working from a theoretical viewpoint, a member of pile coolant studies has dev- elaped cuz equation ihvolving five unknownpmters aad four independent variables. !be "bestwcurrre of this type is currently being fitted to some water type 40 corrosion data. Considerable interest hae been arpressed lately in calculations of the yields of the heavy isotopes under neutron bcenbardment. !be origiaal problem was fonrm- elated to yield infomation on the cross-sections and fields of the heavy isotopes of plutonium and eunerlcium, and at the same timb indicate the validity of earlier calculations of -240 glelds. Since then the problem has been modified to include the m240 isotopes; by congaring the actual and calculated yields of this isotope, it will be possible to dveat a much better estimate for the neutron cspture - cross-sect- Of TIp2 9, one of the links in the chain irom uranium to plutonium. A similar meof cdculation is in progress to determine the yield of fissionable isotope U2 3 from given smounts of thorium. This information is vital to the Study of dorium as a possible reactor fuel. All of the above calculations con- ' sist essentidlly of the solution of airmrlttneous linear differential equations. b addition, a more refined version of the original problem has recently been undertaken. In this version, certain quantities which are treated as constants in the original problem are considered as variables depending both on tFme and the concentration of various isotopes, which in turn depend on time. The result is a set of highly non-linear differential eptions. These are to be solved by Straight-forward numerical. methods on the card-pmgrannned-calculator. Parameters allwed to vc~yin these calculations include the enrichment ratio of the unexposed ma,and the resonance escape probability, fast effect, and average neutron cross- 8ectiOn Of unurposed u238.

Using the standard conversion formula for product build-up, the isotopic concentration of plutonium MS calculated for several values of enrichment. The work was requested by the Advanced Technology Sub-section. The solution of two sets of linear algebraic equations were carried out for the Metallurgy Group. The eqpations arise in formulating the material balance COD- ditions in a separations column. Both sets consisted of seven equations in seven unknowns. These were reduced to six by six systems, and solved on the card- programmed-calculator by techniques recently developed for another totally un- related problem.

-*solver aolutions were estimated. Statistical analyses involving new data -,*e made and additional confidence levels were computed on the datu previously analyzed. Camparisone were made in order to determint which experimental laboratory solution8 resulted in better decontamination than the plant solutions currently used in the scrub columna. An outline of the statistical methods used in computing confidence intarpals on the mean of logarithmic normal distributions, as used for this study, uere requested and submitted. (Oral report: on the results of the analyses sad letter, "Confidence Interval Estimation", April 26, 1954, to W. U. Schulz.) The MUD/t values as reported in HW-26584 vert &sed by personnel of the Separa- tions Technology Sub-section using the original data on $240 and current estimates of the relationships for $240 vs. ncutrons/gram/sec. and neutrons/gram/second. vs. MWD/t. Using these revised MUD/t values and the original g/t dues, a quadratic regression curve was fitted. he resulting curve predicts egproximately lower g/t values for present werating MWD/t levels thsn does the current cme. (Oral report to A. E. Smith.)

A pr- report on the mathematical treatment of fast sources in P-10 piles has been submitted to the Exponential Pile Sub-unit. !bo cases were considered, one vith a fully loaded pile and the other having a sizable reflector below the loaded region. It waa found that a fully loaded pile leads to considerable mathematical simplification, and, therefore, to a less involved and less costly IBM calculating procedure. However, there are technical arguments in favor of the hslf-loaded pile which may offset the computational advantages. Whichever procedure dtFmately followed, the theory for the exponential pile experiments will be much ,-&der than it'is at present, and more accurate diffusion length measurements should result.

!be slowing down of neutrons in reactors is described to a certain extent by the so-called WiJJsins integral equstion. Solutions for.severaJ, special cases have been requested by the Advauced Technology Sub-Section. Since the complexity of this equation prohibita any direct aaalytic solution, a numerical or iterative technique must be used.

Several definite integrals arising in the study of neutron absorption in a cylindrical absorbing rod were mxnerically evaluated. The integrals involved modified Bessel functions the $ functions. The latter were obtained in earlier work from simple recursion relations with the KJ functions, which have recently been published by G. M. Muller in aW-30323. Standard numerical integration techniques were used.

The Boltzmann equstion continued to be a subject of investigation. It is hoped that, with new analytical tools being discovered from time to time, we can eventu- ally use transport theory instead of the less accurate diffusion theory in many more instances than now is practical.

A series of attempts hembeen made to solve the problem of two-phase chemical diffusion which was submitted by the Chemical Research Unit. Thus far, none of these has been succeseful enough to agree at all closely with experimental data. .

- Je-9- - ,- In recent weeks, personnel of the Statistics group have been working in conjunction with personnel of the Inspection & Materials Unit to devise a statistical sampling plan to be applied to the ssmpliw of 1004 connectors. It is felt that the application of statistical methods to some of the inspection programs camled on by Hapid personnel could result in considerable savings in terms of maqmwer snd money. The f'urther analpie of attitude survey data for the Design'Section has been campleted. Bemilts pertinent to the attitudes of ermployees in separate per- oonnel classes within eaeh sub-eection and the Design Planning Unit were supplied to manqement, as well at3 a summary of all camnents these employees wrote on the blanks provided by the questionnaire. (Reports: "Attitude Survey Results-- Design Section", to 0. H. Pilkey, "Attitude Survey Result--Process Engineering Sub-Secticm", to V. D. Nixon, and "Attitude Survey Result--Design Planning Unit", to J. L. Boyd.) An explanation of the use of *log-nonnal distribution was given a member of the radio-chemistry group. Special emphasis was put on the transformation of aaalytical results back to the original population. (Verbal report: April 16, 1954 to D. 0. Miller.) Routine camputational work for the Engineering Department consisted of Special Bequest Bcposure Calculations for 4ril, C~aupNine Metal Studies calculation8 for February, and Lattice Conductance calculations on D-reactor bta from July 1953 to March, 1954, and B-reactor data f'rom November 1953 to April 1954. The conversion of the Classified File frm a manual to a puched card system is continuing. !!he current status of the keypunchingpart of the conversion is as follows: File Records Cards - 80$ complete, Certificate of Destruction - 304 complete, Outgoing Receipts - l5$ complete, Incoming Receipts - 54 coqlete, and miscellaneoua chsnges - strrrted. Last month a plan to convert the holding records of classified copies in personal custody to a mabhine records system was proposed and accepted. Subsequently, the Classified Files supenrision decided to abandon this plan. The earlier plan Of establishing the accountable position of Henford Atomic Products Operation and then the distribution of these copies within Word Atomic Products Operation WBS re-established.

The daily recording for Classified Files of current issues of new documents of destruction of copies, and of outgoing transfers of accountability was begun. The same information is, for the most part, recorded for the period covering the punching of the master accountability records.

A stratified ssmple MS taken of Central Stores' 1953 docking reports to determine if any impmements are possible in the unloading, checking, and storage procedures. The amount of material coming in by parcel post, express, truck freight, and car loads was estimated for each day of the week. The analysis showed, in addition to other factors, that there exists a much larger work load on Mondays.

Regarding the study of utilization of Area Stores vs . Central Stores, data have been campiled on the number of transactions and distribution of dollar value of the orders for Central Stores and each Area Store. In addition, data were co@iled on how much goods each =ea uses, what type, and where it comes from.

This report presents cca~arisonsof tEe costs and effects of alternatfve situations and discusses nonqusntitative factors that could affect management decisions.

It will be recalled that the Telephone operations research program was initiated for the following purposes: 1. To study the routing of calls within the telephone system on the premise that the proportion of incqleted calls could be reduced by a formal analytical method. 2- To study the clerical procedures of the Telephone Unit ,in an effort to eliminate unneceseary paper work. I 3. To make an economic study of toll calls versus leased lines for official uses.

Recommendations in that report to reduce the proportion of incompleted calls by regrsdlng second selectors were accepted by the Telephone Unit. The potential imPmement WLll elblnate a large number of incompleted calls over the period of time remaining until completion of the additional Richland exchange. Business snd official subscribers in the fourth lwel will receive the majority of the improvement. The actual regradlng has been camied out. Ibe second phase of the program, the study of clerical procedures, has also been completed. Results indicated that the Tclephone Unit is performing its internal functions in an efficient manner with a small, well organized clerical staff. The mSJOrity Of changes that could simplify their work involve accounting practices rather than internal procedures. me results of this phase of study will be presented Kith the third phase of the pro- upon campletion of it.

Work has begun on the third phase of the progrsm. In this phase of the study an att-t will be made to provide a mathemstical basis for the selection of an econ- Canic Ilumber of leased lines. Data are presently being collected from leased line and toll tickets in order to secure a knowledge of local patterns in the usage of 10% distance calls. Anticipated subjects of investigation include traffic, delay times, day of week and hour of day fluctuations, and utilization of leased lines.

The 'hansportation operations research program has been started. Preliminary work to date involves scoping the program. The first phase of operations on this ww DECLASSIFIED I gramwSU be to study utllization of vehicles for a section in the 100 Areas.

Security problems in connection with classifiqd copies and the audit function of the Security and Patrol Unit were discussed in detail with the units stper- vision. Broad use of the ixdonnertion available in the Classified File Machine Records and the lncoxporation of rrignificant police information kt0 these records for analysis and reporting purposes was approved. Classified files has not yet concurred with this policy. Security has agreed that the many variables of employee attitude and such measure of risk of mlsp1acing.a classified capy sharjld be mathematically analyzed to determine the most effective ssmpling system to audit chargees perforntance in regard to the handling of classified copies.

Pallet legs have been fabricatad snd will be tested in Central Stores. The purpose of the legs ls to facilitate the stscking of pallets holding uneven items that cannot normslly be ewd. A savings in space wlll be realized by stock- ing these paets several high. DraKZngs of this equipment have been campleted and are in the procesa of reproduction. A procedures wagon to be used for Kngpanels for IBM machines has been fabricated and put into use in the Camputing bullding. It han expedited the wiring of panels by the necessary ccmponenta more accessible.

.rty-six new or revised IBM internal aperatiag procedures were prepared for the Camputing Unit by the Procedures Unit.

Grsphics work on Operations Research programs included development of a plate illustrating a 'ballet" leg design recommended for space conservation use in the Central Stores Warehouse; prepamtion of flow chart work for the "Stand-by Inventory Control Study"; completion of an electrical flow chart for the "Electri- cal Substation Operations Report"; and campletion of special assignments related to the above programs.

Additional graphics services for the Plant Auxiliary Operations Department included preparation of a dummy layout, prellmim study charts and varlous directed assignments relative to issuance of the first issue of the "Proposed Incentive Fee" report; layout of rough organization charts for departmental use; and completion of a series of cost distribution and record charts. For the Plant Auxiliary Operations Departmeat, 14 routine IBM machine reports 5 non-routine Jobs were completed for a total of 19 service requests. FOR TEE RADIOLOGICAL SCIEmcES DEPAR?MEIoT The first of afive-partprelhinary report on the radiation exposure records problem has been completred. "his report wlll describe the existing procedures for - recording and reporting exposure data in five separate parts: Area badges, pen- til meters, special monltorlng instruments, bioassay-internal radiation monitoring, and record roan activities. Each part will describe routine and nomtine procedures aa well as the me~~lyrecorda and reports involved. Upon conrpletlon of the report, a recamaeandatian will be made to the Exposure Records UnLt regarding the porrrible spplicatlan of machine zuethod~to this artramely large data proces- ring pmblm* The problem of predicting nmthematically the distribution of a contaminant at point8 bfn8tream from the effluent duct of a retention basin is receiving further etudy. !be result of this study should enable the Radiological Engineering Section to better control the depositinrr; radioactive materials on the river banks. A subsidisrg problem involves the heat which .the effluent water contains. Since the intake ducts for piles downstream pick up some of this heat, it is very ad- vantage~~to know just where to place the various ducts EO as to avoid as much at3 possible the heat of one pile into y1c next pile downstream. It is per- hrrps obvious thst it is undesirsble to have contaminated water go through the puriiylng and pumping system. A rigoroussolution to either of these problems is. out of the question, since this would demand mspping of the river channel and velocity distributions, both of which suffer season83 vsriations. 'Ehree urperFments have been conducted with sheep to determine the effects of feeding radioactive daterial on the various constituents of the blood. Seasonal, age, und tims effects WFIl be analyzed. !J!he results of these studies will supply pertinent information for radiological health standards. Routine camputational work ror the Radiological Sciences Department consisted of veather c&culations for March, vlnd calculations for Februarg and March, thyroid and rsdioanalysls calculations, snd -tic biology calculations. In addition, extensive sunumrles of sheep tayroid and aquatic biology data were campleted. %'&e data for both summaries cover a four-year period. ThC thyroid-sunnnary consists of a listing of some 35,000 cards by sheep group, animal number, axd date. The aquatic biology sumnary required the calculation of average radioactivity of 8ar~lc8,and involved some 20,000 cards. Graphics work for the Stsndarde.Unit included preparation of two visual aids titled "Highest mosure and Whole Body Expo~ures~';and completion of I contamination measurarrcnt record table combined with a map of the Columbia River.

Three cmswere prepared on the subject '~istributionof Radioactivity in the Columbia River" for Aquatic Biology to use in a paper presented to the American Water Works JaurndL. A large mq of the area sharLng general contamination levels on the railroads was prepared for Biophysics. Additional grwhics services for the Radlologlcel Sciences Department included preparation of prellmlaary lsyoUtS for the new organization charts; paste up and photo retouch for a formal report; and preparation of overlays for contamination recording on maps used in the Standa3.ds Unit chart room.

Five routine IBM reports and 1 non-routine job for a total of 6 IBM'service requests were completed for the Radiological Sciences Department.

-Je-14- DECLASSIFIED Fm THE EMPLOYEE Am PUBLIC REUTIONS mARm The first set of personal accident study reports vere delivered to the Industrial Medical Unit. ltro types of reports were prepared; one shawlng the relstive raplring of organization unite with respect to accidents per person ratio, and one listing those persons vith a large merof accidents during the Quarter. It is plaaned to contiwe these reports on a quarterly basis be@- in May.

A study is being made of the flow of inpatient pagerwork at the Kadlec Hospital. Currently seven to nine separate forme, depending upon the type of treatment, must be completed for each patient. ObJectives will be to eliminate repetitive typing of common information requlred on each of these forms and to improve the flow of the forms.

Reports were prepared to show the occupptional qudlifications of all personnel employed by General Electric at Hanf'ord. These reports will be used to locate employees with experience and training in specified fields other than those fields in which they are now working. A questionnaire has been prepared for use in conjunction wlth the showing of an orientation film to mw eqloyees. !Che purpose of the questioxmdxe is to de- I termine if the film le sewits purpoee in supplying new employees with information on certain GE policies and plans. When a sufficient nuuiber of question- --trcs have been filled aut, the responses will be tabulated and analyzed statisti- -Y The injury control charts for departments andpajor eections have been revised, and wepresently being processed by the Graphics Unit. New expected values and limits of the expected variation of the monthly injury rates were calculated where needed, that is, where a trend in the past year's data made the previously calculated control values no longer agplicsble. The Erqloyee and Public Relatione Department requeeted a summary of one pSrticdW question on the 1953 attitude meydealing with the Suggestion Award system. This waa obtained for personnel classes within units, wlthin sections, and within departments.

Grsphics work for the Employee and Public Relations Deptu-tment included preparation of two rate coslparison charts on "HAP0 Average Rates va. Northwest Area Average"; capletion of a chart titled "HAP0 Age Group Study By Crafts"; preparation of three plates for slides on Hospital Statistics from 1946 to 1953; preparation of two salary study meycharts; and preparation of one lsrge visual aid for training purpoees.

For the mloyee and Public Relations Department 40 routine IBM reports and 4 non-routine Jobs were completed for a total of 44 IBM service requests. FOR TBE FIXANCIAL IIEPARm It was desired by the SF Accountability Section of the Financial Departmint to bow if the factor weights in use for charging uranium from the 300 Area to the 100 Areas give results vhich wee fmrably with the actual weights of buckets of irradiated slw. To do this It- necessary to consider the average weight of both four and eight-inch slugs, the average weight of the aluminum jackets and bollding -8, the blls of dtalnimm in the pile due to corrosion, and the VOlUme of the dug8 (VU&determina the smwnt of water displaced). The weight of water Usplaced by the slugs mtbe considered since the actual bucket weights are obtained by underwatez mi-. !be variation introduced in bucket weights due to the known variations in each of the abwe factors was also considered. (Con- fidential-Undocumented report, "Estimated vs . Observed Bucket Weights", to V. D. Donihee, dated April 28, 1954.)

Data fram recent chemical analyses of five bronze crucibles were analyzed to ob- taln estimates of the uvmrage SF material content and the ssmpling and analytical errors Msociated With these rudyses. A 95s level confidence interval wa8 also found and reported for the true average SF material content for the five crucibles. (Oral report: to C. B. McKee.)

Dats on the "70-58" and impurity content for a sample of 30 shapes case since &ril 1, 1953 were analyzed to determine if there was evidence of a receat change in the average plutonium content for shapes. Based on the recent data, there was no evidence of a change irom the averuge observed spproxlmately a year ago. The precision observed a year ago was also essentially the same as was estimated from the recent data. Therefore, it was recommended that the use of the established factor and sseociated precision be continued and that periodic re-examination be continued. (151-31678,'%evIew of Plutonium Content Factor for Shapes", to C. J. Shortess, Jr ., dated Agril 29, 1954. ) Data has recently been obtained on the eqirical "F" factors computed as the ratio of the chemical assay to X-ray assay for material processed through Redox since February 1, 1954. An analysis XiU be made on this data to determine if there is evidence of nonranicm timeKise variations similar to the deviations observed in cmpirical "F" factors computed during 1453. If nonrandomness is indicated, further investigation Ku1 be required in an effort to determine the source of the trouble.

Work is being started on obtaining an objective method of determining what are reasonable shipper-receiver differences on nitrate shi~mentsdue to the random errors inherent in tfie method of analysis. Until recently, poor unloading techniques at the receiver's plant made such a s-hidy impractical. A short table of precision to be associated with various numbers of predicted grams of product is being prepazad for use by personnel of the Measurement Methods Unit. This table is based on recent shdies cf %he precision of predicted g/t from MWD/t made by personnel of the Technical S+,stistics group.

“k is being continued on the problem of fitting by statistical techniques ,alibration curve to the original calibration data for tank 15-6. This problem will be campleted in the near Arture. As a part of an operations research program on data processing, work on the preparation of flow charts for production data in the Reactor Section has been conducted. Prelhtnazy imestigatians of the flow of production data in the Sepaxatioxu Section hasre been etaxted. Bcisting procedures for the machlne preprvation of gaa and oil reports and for exempt salary distribution were revlsed to conform with requests from the Financial Department.

A report was prepared listing all Genernl Electric enployees at Word by years of semice within groups of 5 years. This listing will be used in setting up the Service Recognition Plan. The payroll procedure for Camputing has been ravised to cmrehend the changes made to the t- card. The procedure has been installed and is currently be- used. In addition to the changes made in connection with the new time card, the separate listings of debit and credit vouchers are eliminated. Certain special payments such as military duty and encaapment Kill now be identified and msy be segregated for future statistical and salary distributionpurposes. Also, several revisions were deto eliminate or ccmibine processing steps. During this revision groundwork was laid for the )r revision to be cmleted by July 1. Baaed on the information obtaixd -ALJ~the processing of the payroll on the revised procedure for the first week, it appears that operating time has been reduced by several hours.

As part of an operations research program on data processing, work on an investigation of the usefulness of input-output models at Hanford Atomic Products Operation has begun with discussions with members of the Financial Department.
