Donnell, P.E., Project Director U.S. Nuclear Regulatory Commission June 19, 2000 ATTN: Document Control Desk Washington, D.C. 20555-0001 SUBMITTAL OF COMMITMENT RESOLUTION LETTER #34 INFORMATION DOCKET NO. 72-22 / TAC NO. L22462 PRIVATE FUEL STORAGE FACILITY PRIVATE FUEL STORAGE L.L.C. Reference: PFS Letter, Donnell to U.S. Nuclear Regulatory Commission, Commitment Resolution Letter # 34, dated June 2, 2000 In the referenced letter, Private Fuel Storage (PFS) committed to provide the NRC with information on tipover of a cask transporter, propane vapor cloud dispersion, and a revised calculation package associated with bearing capacity and sliding stability of the cask storage pads and the Canister Transfer Building. This letter provides the informational commitments and the calculation package. Attachment 1 contains the calculation package that addresses bearing capacity and sliding stability analyses of the cask storage pads and the Canister Transfer Building. The package consists of the following three calculations which have been revised to address issues discussed in the referenced letter: PFSF Calculation No. 05996.02-G(B)-4, Stability Analysis of Storage Pad, Rev. 6, Stone & Webster. PFSF Calculation No. 05996.02-G(B)-5, Bases for Geotechnical Parameters Provided in Geotechnical Design Criteria, Rev. 2, Stone & Webster. PFSF Calculation No. 05996.02-G(B)-1 3, Stability Analyses of the Canister Transfer Building Supported on a Mat Foundation, Rev. 3, Stone & Webster. IQ rPL~s)jCb U.S. NRC 2 June 19, 2000 Attachment 2 provides the results of an evaluation of the stability of the cask transporter when carrying a storage cask, assuming it is subjected to the PFSF design basis ground motion, or to the design tornado-driven missile. The evaluation concludes that the cask transporter and the storage cask will remain upright and not tip over when subjected to these events. Attachment 3 contains the results of analyses of postulated propane releases from the relatively large propane storage tank(s) that will be located a minimum distance of 1,800 ft south or southwest of the Canister Transfer Building, considering dispersion and delayed ignition. The analyses assessed several different postulated propane leakage scenarios, including rupture of a 20,000 gallon propane tank, rupture of a 5,000 gallon propane tank, severance of a 2 inch vapor line at the tank, and severance of a 2 inch liquid line at the tank. As discussed in Section 8.2.4 of the PFSF SAR, propane vapor will be supplied from the storage tank(s) to the Canister Transfer Building and Security and Health Physics Building, using a compressor to provide the motive force. Based on building heating requirements, a 2 inch line is adequate for this purpose. Analysis of a 2 inch propane liquid line rupture was included for completeness, but liquid propane will not be supplied from the tank(s). It was assumed that variable winds were directed towards the Canister Transfer Building and cask storage area under stable atmospheric conditions (atmospheric stability class F), to minimize dispersion of the propane vapor in the plumes. In the analyses of plume formation for the postulated 2 inch line ruptures, wind speeds were varied between 1 to 5 meters per second to determine the wind speed that resulted in a concentration of gas at the lower explosive limit (LEL) approaching nearest to the Canister Transfer Building and cask storage area. A wind speed of 3 meters per second, combined with atmospheric stability class F, maximized this explosive concentration travel distance and was considered to represent the worst case meteorology. In all cases analyzed, with the exception of postulated rupture of a 20,000 gallon tank, propane-air concentrations diminished to below the LEL at distances much shorter than the 1,800 ft minimum distance from the tank(s) to the Canister Transfer Building and the nearest storage casks. However, in the case of postulated rupture of a 20,000 gallon tank, explosive concentrations of propane traveled to distances beyond 1,800 ft under the worst case meteorological conditions evaluated. Therefore, PFS will design the propane storage for supplying propane to heat the Canister Transfer Building and Security and Health Physics Building with 4 separate tanks, with each tank having a capacity of less than or equal to 5,000 gallons for a total capacity of not more than 20,000 gallons. The 4 tanks shall be separated by missile walls to ensure that a single missile driven by the design tornado can not rupture more than one tank. The design will assure that it is not credible that more than one of the tanks could rupture at any given time. Each propane tank shall have an excess flow shutoff valve that automatically isolates upon sensing high flow that could be due to a downstream line rupture or large leak. In U.S. NRC 3 June 19, 2000 addition, a single excess flow shutoff valve shall be located on the 2 inch piping header that supplies propane to the Canister Transfer Building and Security and Health Physics Building, downstream of the connection points of the lines from the 4 propane tanks. This valve shall also be designed to automatically close upon sensing high flow conditions indicative of a line rupture or large leak. This system of automatic isolation valves will serve to automatically isolate pipeline ruptures, thus preventing significant leakage of propane in the vicinity of the Canister Transfer Building or Security and Health Physics Building. The analyses provided in Attachment 3 also assess overpressures that could occur from postulated propane vapor cloud explosions, assuming ignition occurs near the center of the plumes for each of the 4 propane release cases evaluated. The effects of explosions were analyzed using the TNT energy equivalent methodology, described in PFSF SAR Section 8.2.4. In all cases analyzed, with the exception of postulated rupture of a 20,000 gallon tank, overpressures decreased to less than 1 psi prior to reaching the Canister Transfer Building and nearest storage casks. The PFSF license application will be updated as required to reflect the above information, and that included in the attachments to this letter, and submitted to the NRC by June 23, 2000. If you have any questions regarding this response, please contact me at 303-741-7009. Sincerely • Donnell Project Director Private Fuel Storage L.L.C.

  • UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION
    UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION SPONSORED and DISTRIBUTED by the 1998 ARIZONA (Includes revisions through 2010) FOREWORD Publication of these Uniform Standard Specifications and Details for Public Works Construction fulfills the goal of a group of agencies who joined forces in 1966 to produce such a set of documents. Subsequently, in the interest of promoting county-wide acceptance and use of these standards and details, the Maricopa Association of Governments accepted their sponsorship and the responsibility of keeping them current and viable. These specifications and details, representing the best professional thinking of representatives of several Public Works Departments, reviewed and refined by members of the construction industry, were written to fulfill the need for uniform rules governing public works construction performed for Maricopa County and the various cities and public agencies in the county. It further fulfills the need for adequate standards by the smaller communities and agencies who could not afford to promulgate such standards for themselves. A uniform set of specifications and details, updated and embracing the most modern materials and construction techniques will redound to the benefit of the public and the private contracting industry. Uniform specifications and details will eliminate conflicts and confusion, lower construction costs, and encourage more competitive bidding by private contractors. The Uniform Standard Specifications and Details for Public Works Construction will be revised periodically and reprinted to reflect advanced thinking and the changing technology of the construction industry. To this end a Specifications and Details Committee has been established as a permanent organization to continually study and recommend changes to the Specifications and Details.

  • California Bearing Ratio (CBR)
    California Bearing Ratio (CBR) • California Bearing Ratio (CBR) is a penetration test for evaluation of the mechanical strength of road subgrades, sub-base and base courses. It was developed by the California Department of Transportation. • The test is performed by measuring the pressure required to penetrate a soil sample with a plunger of standard area. The measured pressure is then divided by the pressure required to achieve an equal penetration on a standard crushed rock material. or • The test is performed by measuring the load required to penetrate a soil sample with a plunger of standard area.
