Table 2.Iii.1. Fissionable Isotopes1
FISSIONABLE ISOTOPES Charles P. Blair Last revised: 2012 “While several isotopes are theoretically fissionable, RANNSAD defines fissionable isotopes as either uranium-233 or 235; plutonium 238, 239, 240, 241, or 242, or Americium-241. See, Ackerman, Asal, Bale, Blair and Rethemeyer, Anatomizing Radiological and Nuclear Non-State Adversaries: Identifying the Adversary, p. 99-101, footnote #10, TABLE 2.III.1.

FACT SHEET Office of Public Affairs Phone: 301-415-8200 Email: [email protected] Uranium Recovery Background The production of fuel for nuclear power plants starts with taking uranium ore from the ground and then purifying and processing it through a series of steps. Uranium recovery focuses on extracting natural uranium ore from the earth and concentrating (or milling) that ore. These recovery operations produce a product, called "yellowcake," which is then transported to a succession of fuel cycle facilities where the yellowcake is transformed into fuel for nuclear power reactors. In addition to yellowcake, uranium recovery operations generate waste products, called byproduct materials, that contain low levels of radioactivity. The NRC does not regulate uranium mining or mining exploration, but does have authority over milling of mined materials and in situ processes used to recover uranium, as well as mill tailings. Today’s conventional uranium mills and in situ recovery (ISR) facilities are operating safely and in a manner that is protective of the environment. The NRC regulates these facilities in close coordination with other Federal agencies and State and Tribal governments and provides technical support and guidance to those Agreement States that have authority over uranium recovery activities. Discussion The NRC becomes involved in uranium recovery operations when the ore is processed and physically or chemically altered. This happens either in a conventional, heap leach uranium mill, or ISR. For that reason, the NRC regulates ISR facilities as well as uranium mills and the disposal of liquid and solid wastes from uranium recovery operations (including mill tailings). -

A Fissile Material Cut-Off Treaty N I T E D Understanding the Critical Issues N A
U N I D I R A F i s s i l e M a A mandate to negotiate a treaty banning the production of fissile material t e r i for nuclear weapons has been under discussion in the Conference of a l Disarmament (CD) in Geneva since 1994. On 29 May 2009 the Conference C u on Disarmament agreed a mandate to begin those negotiations. Shortly t - o afterwards, UNIDIR, with the support of the Government of Switzerland, f f T launched a project to support this process. r e a t This publication is a compilation of various products of the project, y : that hopefully will help to illuminate the critical issues that will need to U n be addressed in the negotiation of a treaty that stands to make a vital d e r contribution to the cause of nuclear disarmament and non-proliferation. s t a n d i n g t h e C r i t i c a l I s s u e s UNITED NATIONS INSTITUTE FOR DISARMAMENT RESEARCH U A Fissile Material Cut-off Treaty N I T E D Understanding the Critical Issues N A Designed and printed by the Publishing Service, United Nations, Geneva T I GE.10-00850 – April 2010 – 2,400 O N UNIDIR/2010/4 S UNIDIR/2010/4 A Fissile Material Cut-off Treaty Understanding the Critical Issues UNIDIR United Nations Institute for Disarmament Research Geneva, Switzerland New York and Geneva, 2010 Cover image courtesy of the Offi ce of Environmental Management, US Department of Energy. -
NNSA Should Clarify Long-Term Uranium Enrichment Mission Needs and Improve Technology Cost Estimates
United States Government Accountability Office Report to Congressional Committees February 2018 NUCLEAR WEAPONS NNSA Should Clarify Long-Term Uranium Enrichment Mission Needs and Improve Technology Cost Estimates GAO-18-126 February 2018 NUCLEAR WEAPONS NNSA Should Clarify Long-Term Uranium Enrichment Mission Needs and Improve Technology Cost Highlights of GAO-18-126, a report to Estimates congressional committees Why GAO Did This Study What GAO Found NNSA has several mission needs for The National Nuclear Security Administration (NNSA), a separately organized enriched uranium, including providing agency within the Department of Energy (DOE), is taking or plans to take four LEU to fuel a nuclear reactor that actions to extend inventories of low-enriched uranium (LEU) that is unobligated, produces tritium—a key isotope used or carries no promises or peaceful use to foreign trade partners until about 2038 in nuclear weapons. NNSA has a to 2041. Two of the actions involve preserving supplies of LEU, and the other pressing defense need for unobligated two involve diluting highly enriched uranium (HEU) with lower enriched forms of LEU to fuel this reactor, meaning the uranium to produce LEU. GAO reviewed these actions and found the actual uranium, technology and equipment costs and schedules for those taken to date generally align with estimates. used to produce the LEU, must be U.S. NNSA and GAO have identified risks associated with two of these actions. One in origin. Because the United States of these risks has been resolved; NNSA is taking steps to mitigate another, while lost its only source of unobligated LEU production in 2013, the supply is finite. -
Compilation and Evaluation of Fission Yield Nuclear Data Iaea, Vienna, 2000 Iaea-Tecdoc-1168 Issn 1011–4289
IAEA-TECDOC-1168 Compilation and evaluation of fission yield nuclear data Final report of a co-ordinated research project 1991–1996 December 2000 The originating Section of this publication in the IAEA was: Nuclear Data Section International Atomic Energy Agency Wagramer Strasse 5 P.O. Box 100 A-1400 Vienna, Austria COMPILATION AND EVALUATION OF FISSION YIELD NUCLEAR DATA IAEA, VIENNA, 2000 IAEA-TECDOC-1168 ISSN 1011–4289 © IAEA, 2000 Printed by the IAEA in Austria December 2000 FOREWORD Fission product yields are required at several stages of the nuclear fuel cycle and are therefore included in all large international data files for reactor calculations and related applications. Such files are maintained and disseminated by the Nuclear Data Section of the IAEA as a member of an international data centres network. Users of these data are from the fields of reactor design and operation, waste management and nuclear materials safeguards, all of which are essential parts of the IAEA programme. In the 1980s, the number of measured fission yields increased so drastically that the manpower available for evaluating them to meet specific user needs was insufficient. To cope with this task, it was concluded in several meetings on fission product nuclear data, some of them convened by the IAEA, that international co-operation was required, and an IAEA co-ordinated research project (CRP) was recommended. This recommendation was endorsed by the International Nuclear Data Committee, an advisory body for the nuclear data programme of the IAEA. As a consequence, the CRP on the Compilation and Evaluation of Fission Yield Nuclear Data was initiated in 1991, after its scope, objectives and tasks had been defined by a preparatory meeting. -
A New Methodology for Determining Fissile Mass in Individual Accounting Items with the Use of Gamma-Ray Spectrometry*
BNL-67176 A NEW METHODOLOGY FOR DETERMINING FISSILE MASS IN INDIVIDUAL ACCOUNTING ITEMS WITH THE USE OF GAMMA-RAY SPECTROMETRY* Walter R. Kane, Peter E. Vanier, Peter B. Zuhoski, and James R. Lemley Brookhaven National Laboratory Building 197C, P. O. Box 5000, Upton, NY 11973-5000 USA 631/344-3841 FAX 631/344-7533 Abstract In the safeguards, arms control, and nonproliferation regimes measurements are required which give the quantity of fissile material in an accounting item, e.g., a standard container of plutonium or uranium oxide. Because of the complexity of modeling the absorption of gamma rays in high-Z materials, gamma-ray spectrometry is not customarily used for this purpose. Gamma-ray measurements can be used to determine the fissile mass when two conditions are met: 1. The material is in a standard container, and 2. The material is finely divided, or a solid item with a reproducible shape. The methodology consists of: A. Measurement of the emitted gamma rays, and B. Measurement of the transmission through the item of the high-energy gamma rays of Co-60 and Th-228. We have demonstrated that items containing nuclear materials possess a characteristic "fingerprint" of gamma rays which depends not only on the nuclear properties, but also on the mass, density, shape, etc.. The material's spectrum confirms its integrity, homogeneity, and volume as well. While there is attenuation of radiation from the interior, the residual radiation confirms the homogeneity of the material throughout the volume. Transmission measurements, where the attenuation depends almost entirely on Compton scattering, determine the material mass. -
Two Paths to a Nuclear Bomb Iran Has Historically Pursued Work on Both Uranium- and Plutonium-Weapons Programs, Western O Cials Say
Two Paths to a Nuclear Bomb Iran has historically pursued work on both uranium- and plutonium-weapons programs, Western ocials say.

Nuclear Reactor Realities
Page 1 of 26 Nuclear Reactor Realities NUCLEAR REACTOR REALITIES (An Australian viewpoint) PREFACE Now that steam ships are no longer common, people tend to forget that nuclear power is just a replacement of coal, oil or gas for heating water to form steam to drive turbines, or of water (hydro) to do so directly. As will be shown in this tract, it is by far the safest way of doing so to generate electricity economically in large quantities – as a marine engineer of my acquaintance is fond of saying. Recently Quantum Market Research released its latest Australian Scan (The Advertiser, Saturday April 17, 2012, p 17). It has been tracking social change by interviewing 2000 Australians annually since 1992. In the concerns in the environment category, “[a]t the top of the list is nuclear accidents and waste disposal” (44.4 per cent), while “global warming” was well down the list of priorities at No 15, with only 27.7 per cent of people surveyed rating the issue as “extremely serious.” Part of the cause of such information must be that people are slowly realising that they have been deluded by publicity about unverified computer models which indicate that man’s emissions of CO2 play a major part in global warming. They have not yet realised that the history of the dangers of civilian nuclear power generation shows the reverse of their images. The topic of nuclear waste disposal is also shrouded in reactor physics mysteries, leading to a mis-placed general fear of the unknown. In this article only nuclear reactors are considered. -

INTRODUCTION History of the Proposal to Cut Off the Production -of Fissile Material for Nuclear Weapons Although the original nuclear weapons control proposals such as the 1946 Baruch Plan - focused on the control of nuclear weapons materials, recent arms control negotiations have focused principally on the control of long-range nuclear weapons delivery systems. This has been in part due to the shift in the focus of the nuclear arms race from the quantitative to the qualitative. In part also it resulted from the Soviet Union's reluctance to allow intrusive verification arrangements.
