Box 2001 Oak Ridge, Tennessee 37831 — October 11, 1994 Distribution PADUCAH ANNUAL SITE ENVIRONMENTAL REPORT FOR CALENDAR YEAR 1993 Enclosed for your information is a copy of the Paducah Annual Site Environmental Report for 1993. This report includes the results from on-site and off-site environmental monitoring activities, describes actions to comply with environmental regulations, and discusses the overall environmental impacts of Department of Energy (DOE) activities on the surrounding area. This report is prepared annually for distribution to the public; news media; and local, state, and federal agencies. The report was prepared for the DOE by our contractor Martin Marietta Energy Systems, Inc. (Energy Systems). This years report is somewhat different than previous reports. An attempt was made to streamline the document and provide more summary information. The detailed data has been incorporated into a separate report. Likewise, a summary "pamphlet" is available this year. Its purpose is to convey key environmental monitoring information to those without a technical background. Comments on this report are welcome. All comments will be considered during the writing of the next report. There is a comment sheet and mailing address at the end of the report. The monitoring data and subsequent data analyses have been collected and performed in accordance with controlled operating procedures. Likewise, both DOE and Energy Systems personnel have reviewed this document for accuracy. To the best of my knowledge, this report accurately summarizes and discusses the results of the 1993 environmental monitoring program.

    An Access-Dictionary of Internationalist High Tech Latinate English Excerpted from Word Power, Public Speaking Confidence, and Dictionary-Based Learning, Copyright © 2007 by Robert Oliphant, columnist, Education News Author of The Latin-Old English Glossary in British Museum MS 3376 (Mouton, 1966) and A Piano for Mrs. Cimino (Prentice Hall, 1980) INTRODUCTION Strictly speaking, this is simply a list of technical terms: 30,680 of them presented in an alphabetical sequence of 52 professional subject fields ranging from Aeronautics to Zoology. Practically considered, though, every item on the list can be quickly accessed in the Random House Webster’s Unabridged Dictionary (RHU), updated second edition of 2007, or in its CD – ROM WordGenius® version. So what’s here is actually an in-depth learning tool for mastering the basic vocabularies of what today can fairly be called American-Pronunciation Internationalist High Tech Latinate English. Dictionary authority. This list, by virtue of its dictionary link, has far more authority than a conventional professional-subject glossary, even the one offered online by the University of Maryland Medical Center. American dictionaries, after all, have always assigned their technical terms to professional experts in specific fields, identified those experts in print, and in effect held them responsible for the accuracy and comprehensiveness of each entry. Even more important, the entries themselves offer learners a complete sketch of each target word (headword). Memorization. For professionals, memorization is a basic career requirement. Any physician will tell you how much of it is called for in medical school and how hard it is, thanks to thousands of strange, exotic shapes like <myocardium> that have to be taken apart in the mind and reassembled like pieces of an unpronounceable jigsaw puzzle.

  • The Gaseous Diffusion Process
    The Gaseous Diffusion Process The Portsmouth Gaseous Diffusion Plant, built in 1953-1954, produces enriched uranium hexafluoride (UF6) for commercial power reactors. In the past highly enriched uranium hexafluoride 235 was produced for the U.S. Navy. Enriched UF6 is material that contains the isotope U in assays (concentrations) greater than 0.711 weight percent. Commercial power plants currently use uranium enriched to the 3 to 5 percent range. The plant is capable of producing a range of U235 assays from 0.2% to over 97%. In late 1991, the equipment that produced high assay uranium was taken off line and placed in long term shutdown. High assay material that was declared excess by the US Navy and Department of Energy was fed into the cascade and blended down to the assays used by commercial power plants. This refeed project was completed in July 1998. It is possible that other high assay material will be declared excess in the future and would possibly be blended down at PORTS. It is also possible that high assay production could be resumed in the future. The plant's certification under the Nuclear Regulatory Commission (NRC) limits the maximum assay to 10%. Enrichment is accomplished using gaseous diffusion technology as the name implies. The gaseous diffusion cascade consists of many stages of equipment connected in series, i.e., in a cascade arrangement. Each stage consists of an electric motor, a compressor, and a converter which contains 235 a porous membrane through which the lighter U F6 diffuses at a slightly faster rate than the heavier 238 U F6.

    20-Mar-20 Lecture 6-8 ACTINIDE SERIES (5f- elements) 4th year (Micro/Chem- Botany/Chem and Biochemistry) 18 Occurrence and Preparation of the Elements • Ac, Th, Pa, U are naturally occur • All known isotopes of all actinide metals are radioactive. • Thorium (Th) occurs in monazite sands, which are up to 20% ThO2. • Chemically it can be prepared from thermal decomposition of the iodide (de Boer process): ThI4 → Th + 2I2 • Uranium (U) occurs (at about 0.1%) in uraninite ores as U3O8, and carnotite as K2(UO2)2(VO4)2·3H2O. 19 1 20-Mar-20 Occurrence and Preparation of the Elements • The transuranic elements must all be prepared artificially. • About 1200 tonnes of plutonium (Pu) have been produced worldwide in reactors! 20 Actinide Metals Preparation • Reduction of AnF3 or AnF4 with vapors of Li, Mg, Ca or Ba at 1100 - 1400°C • Chlorides and oxides can be similarly reduced. Example: • Am can be Chemically prepared by reduction of AmF3 with Ba: 3Ba(g) + 2AmF3 → 3BaF2 + 2Am • Or by reduction of americium oxide with lanthanum (La) at 1200oC: Am2O3 + 2La → La2O3 + 2Am 21 2 20-Mar-20 Chemical reactivity of Actinides • Actinides are Highly reactive metals, especially when finely divided. • Typically react with: • air → tarnishing • boiling water or dilute acid → releasing Hydrogen • most non-metals in direct combination • Alkalies have no effect. 22 Oxides and hydroxides • Some actinides can exists in several oxide forms such as An2O3, AnO2, An2O5 and AnO3. • For all actinides, oxides AnO3 are amphoteric and An2O3, AnO2 and An2O5 are basic, they easily react with water, forming bases: An2O3 + 3 H2O → 2 An(OH)3.

  • Mining, Milling, Conversion, and Enrichment of Uranium Ores
    MINING, MILLING, CONVERSION, AND ENRICHMENT OF URANIUM ORES Presented by Lisa Loden Export Control Implementation Global Nuclear Security Technology Division Oak Ridge National Laboratory Oak Ridge, TN 37830 Based on the slides of the late Dr. Clarence J. Hardy Past President Pacific Nuclear Council Secretary, Australian Nuclear Association Managing Director, Nuclear Fuel Australia Ltd July 19, 2011 Uranium Background Key points over 150 years •1789 – Uranium was discovered by Klaproth in Germany and named after the planet Uranus recently discovered by Herschel. •1896 – Professor Becquerel in Paris discovered radioactivity in uranium minerals; radium was then discovered by Mme. Curie in Paris. •1910 – Dr. Soddy in Cambridge, UK, proposed “isotopes” for atoms with different atomic weights but identical chemical properties. •1913 – Professor Thomson at Cambridge showed neon had “isotopes,” and, therefore, other elements were likely to have them, too. •1932 – Dr. Chadwick at Cambridge discovered the neutron. •1935 – Dr. Dempster in Chicago showed uranium contained 0.7% of uranium-235 and the rest was uranium-238. Uranium structure was shown to be 92 p and 146 n in U-238; 92 p and 143 n in U-235. Background to the Nuclear Fuel Cycle •1939 – Discovery of fission of uranium by Hahn and Strassman in Germany with extra neutrons released gave rise to the possibility of a chain reaction. •1939–1942 – Concept of an atomic bomb was developed in UK, U.S., and Germany. •1942 – Start of the Manhattan Project and the need for the nuclear fuel cycle with uranium ore processing, uranium enrichment, plutonium production, etc. •1942 – Chemical and physical separation processes became very important for the production of large amounts of uranium-235 and plutonium.

The fuel would contain the fissile material needed to support the fission process. The neutrons generated by the fission process had to be slowed by the moderator so that they could initiate addi- tional fission reactions. The heat that resulted from this process had to be removed by the coolant.
