Nuclear Material Accounting and Control at Radiochemical Plants RU0110709 November 2-6,1998 Obninsk, Russia PROCEEDINGS OF THE TRIPARTITE SEMINAR ON Nuclear Material Accounting and Control at Radiochemical Plants Hosting: Ministry of Atomic Energy of Russian Federation (Minatom) State Scientific Centre of Russian Federation Institute of Physics and Power Engineering named after A.I.Leipunski Sponsoring: Minatom RF Department of Energy (DOE) USA Joint Research Centre of European Commission (JRC), Ispra, Italy PAGES ARE MISSING IN THE ORIGINAL DOCUMENT Printed at the A.I. Leipunsky Institute of Physics and Power Engineering, Bondarenko sq. 1, Obninsk, Russia, 249020. Foreword Upgrading of the state nuclear materials control and accounting (NMC&A) system at the nuclear installations of Russia, including radiochemical plants, has assumed the primary importance. The significant intellectual, financial and materials resources from the USA and European Union were aimed in fraim of international cooperation to solve this task. The numerous results gained in the last years requires its disscussion and analysis so that it could be possible to use its results and to coordinate future plans with maximum efficiency. According to the Nuclear Safety Declaration signed at the Moscow meeting of April 19-20, 1996 by the heads of eight states and in view of the necessity to discuss the results of the work which is under way in Russian radiochemical plants, M IN ATOM took the initiative to organize a tripartite seminar on NMC&A in the above mentioned plants with participation of experts from Russia, European Union and Department of Energy, USA. This initiative was the logical continuation of former one on organisation of similar seminar for the Uranium Fuel Fabrication Plants in April of 1997. The problems of creation and operation of NMC&A systems and their components at radiochemical plants were discussed in seminar during November 2 - 6 of 1998. There were 63 Russian and 25 foreign participants in seminar. The seminar programme includes following sessions and articles: 1. The aspects of State nuclear material control and accountancy (NMC&A) • principal NMC&A requirements, NMC&A systems development, NMC&A supervision in radio- chemical plants; • nuclear fuel cycle in Russia, nuclear material flows and characteristics in the course of nuclear reactor spent fuel reprocessing. 2. NMC&A in radiochemical plants and at separate stages of reprocessing of spent nuclear fuel and irradiated fuel elements of commercial reactors • radiochemical plants which reprocess irradiated fuel elements of Russian and US commercial reactors; • radiochemical plants which reprocess spent nuclear fuel from Russian, French and UK reactors. 3. NMC&A in storage facilities of radiochemical plants • plutonium dioxide storage; • spent fuel subassemblies storage; • recovered uranium storage. 4. NMC&A computerization, material balance assessment, preparation of reports • computerized system development • data processing and management; • computerized system quality testing and verification. 5. Qualitative and Quantitative measurements in NMC&A at radiochemical plants destructive analysis techniques • non-destructive analysis and quantitative measurements based on gamma- and neutron radiation • mass/volume measurements of solutions • requirements for the accuracy and precision of measurements in terms of NMC&A, measurement quality assurance. Those who organized this seminar hope very much that the exchange of experience gained by the participants of the meeting will be of great help in tackling the task of developing efficient nuclear material control and accounting systems in radiochemical plants of Russia. This book contens all reports which were presented by seminar participants.

  • Study on Japan's Nuclear Materials
    Study on Japan's Nuclear Materials China Arms Control and Disarmament Association China Institute of Nuclear Information and Economics September 2015 Foreword The nuclear accident in March 2011 in Fukushima, Japan brought a disaster to the safety of local residents and to the environment of surrounding regions. However, the Japanese government failed to inform the international community of the accident in a timely, accurate, and comprehensive manner. The accident's consequential impacts still linger on today, and the international community is still highly concerned about the safety of Japan’s nuclear facilities. In early 2014, media reports held that around 331 kilograms of weapon-grade plutonium had been stored by Japan for years. And in fact, Japan has stored a lot of sensitive nuclear materials for a long time, which far exceeds its actual need. The imbalance between supply and demand of nuclear materials in Japan has given rise to the concern of and questions raised by the international community. Why does Japan store nuclear materials in such a large amount? How to ensure their safety? How to effectively prevent disasters similar to the Fukushima nuclear accident from happening again? How to ensure that these materials will be used exclusively for peaceful purposes? What measures should be taken to solve this serious imbalance of supply and demand of nuclear materials in Japan? These are questions that are often raised. Regretably, the Japanese government has yet to answer these questions. In September 2015, the Japanese Diet ratified the new bills. In recent years, right-wings forces in Japan have kept denying the history of aggression of Japan and advocated the revision of Japan's "Peace Constitution", Which have aroused vigilance among all peace-loving people.

It is an independent group of arms-control and nonproliferation experts from seventeen countries, including both nuclear weapon and non-nuclear weapon states. The mission of the IPFM is to analyze the technical bases for practical and achievable policy initiatives to secure, consolidate, and reduce stockpiles of highly enriched urani- um and plutonium. These fissile materials are the key ingredients in nuclear weapons, and their control is critical to nuclear disarmament, halting the proliferation of nuclear weapons, and ensuring that terrorists do not acquire nuclear weapons. Both military and civilian stocks of fissile materials have to be addressed. The nuclear weapon states still have enough fissile materials in their weapon and naval fuel stock- piles for tens of thousands of nuclear weapons. On the civilian side, enough plutonium has been separated to make a similarly large number of weapons. Highly enriched ura- nium fuel is used in about one hundred research reactors.

Previous GAO reports on systems used to safeguard nuclear materials pointed ut weaknesses in material accountability systems resulting from state-of-thij-art limitations and the need for tighter hysical ec'irity requirements. After the National Security Council determined that material unaccounted for" (UPF) data could be relased publicly, tha uclear Regulatory Commission (NBC) and the Department of Energy (DOE) released separate reports in August 1977 on special nuclear material inveEtory differences. The data presented in these reports were different from that forally provided GAO and the Congress, The agencies explained that the differences resulted primarily from their efforts t refine and expand the data originally provided. GAO determined that the differences resulted primarily from CC! efforta to adjust the oriqinal data provided GAO by deleting non-aOF items which were included in the nOU figures originally provided and separating low elnriched uranium from high enriched uranium in the UE data. Another major difference in reported UIOF related to COB's Uta i-a Gaseous Diffusion Plant at Portsmoutb, Oio.

  • Improving Materials Accountancy for Reprocessing Using Hirx
    Improving Materials Accountancy for Reprocessing using HiRX Ben Cipitia, Michael McDaniela, George Havrillab, Michael Collinsc aSandia National Laboratories Albuquerque, New Mexico, United States bLos Alamos National Laboratories Los Alamos, New Mexico, United States cKornizu Scientific Monument, Colorado, United States Abstract. The High Resolution X-Ray (HiRX) technology has the potential to replace K-Edge and Hybrid K-Edge Densitometry (HKED) for routine accountability measurements in reprocessing. This technology may significantly reduce plutonium measurement uncertainty in a simpler and less costly instrument. X-ray optics are used to generate monochromatic excitation of a sample and selectively collect emitted x-rays of the target elements. The result is a spectrum with a peak specific to one element with negligible background. Modeling was used to examine how safeguards could be improved through the use of HiRX at existing aqueous reprocessing plants. This work utilized the Separation and Safeguards Performance Model (SSPM), developed at Sandia National Laboratories, to examine how reduced measurement uncertainty decreases the overall measurement error. Material loss scenarios were also modeled to determine the effect on detection probability for protracted diversion of nuclear material. Current testing of HiRX is being used to inform the modeling effort, but a 0.1% measurement uncertainty for uranium and plutonium concentration is an optimistic goal based on laboratory results. Modeling results showed that a three-fold improvement in the overall safeguards performance of a plant if the 0.1% uncertainty goal can be achieved. The modeling results will be presented along with a discussion of the current experimental campaign results. In addition, a qualitative cost analysis will be presented to compare the use of HiRX with HKED.

  • Tripartite Enrichment Project: Safeguards at Enrichment Plants Equipped with Russian Centrifuges
    IAEA-SM-367/8/02 TRIPARTITE ENRICHMENT PROJECT: SAFEGUARDS AT ENRICHMENT PLANTS EQUIPPED WITH RUSSIAN CENTRIFUGES A.PANASYUK, A.VLASOV, S.KOSHELEV The Ministry of the Russian Federation on Atomic Energy, Moscow, Russian Federation T.SHEA, D.PERRICOS International Atomic Energy Agency, Department of Safeguards, Vienna, Austria D. YANG, S.CHEN The China Atomic Energy Authority, Beijing, China I. INTRODUCTION This Paper describes major results of the work undertaken in the Tripartite Enrichment Project carried out under an Agreement between the IAEA the Ministry of the Russian Federation on Atomic Energy ( Minatom ), and under a Contract between the IAEA and the China Atomic Energy Authority (CAEA). The complete results of the work are published by the Agency in Tripartite Enrichment Project Summary and Task Reports. In 1993, the Government of the People’s Republic of China informed the Agency that China had decided on a voluntary basis to add the Shaanxi Uranium Enrichment Plant to the list of eligible facilities under the Voluntary Offer Safeguards Agreement (INFCIRC/369). The Plant was under construction at the time. After consultations, the Agency selected the Shaanxi Plant in September of 1997 for the implementation of safeguards. The Agency realized that the safeguards approach used at gas centrifuge uranium enrichment facilities in other States would not be fully applicable. Chief among the reasons for this conclusion were the observations that enrichment plants incorporating Russian gas centrifuges are designed for a much greater degree of operational flexibility than other plants, and that travel conditions to the Shaanxi Plant at least at present are not compatible with requirements for unannounced access at the facility for the performance of unannounced inspections in the cascade area.

  • EMD-80-38 Nuclear Fuel Reprocessing and the Problems Of
    BY THE COMPTROLLER GENERAL ll(s3cj *Repor ToThe Congress OF THE UNITED STATES Nuclear Fuel Reprocessing And The Problems Of Safeguarding Against The Spread Of Nuclear Weapons In 1977 the executive branch reversed its long- standing support for nuclear fuel reprocessing, primarily because of the risk of spreading nu- clear weapons. GAO reviewed safeguards technology designed to reduce such risks in Federal reprocessing facilities and found that concerns are warranted. Material in sufficient quantities to construct a nuclear weapon could be diverted and go undetected for a long time. Effective international control and safeguards over the production, storage, and use of sepa- rated plutonium are lacking. The United States should increase its efforts to --develop and ensure the use of effective safeguards for reprocessing facilities and --establish, in conjunction with major nuclear fuel users, suppliers, and re- processors, an international system to control the storage and use of excess plutonium. s EMD-80-38 MARCH 18,198O To the President of the Senate and the Speaker of the Hous& of Representatives This report discusses the problems of safeguarding nuclear spent fuel reprocessing facilities and concludes that the administration's policy of indefinitely deferring commercial reprocessing within the United States has. hampered research and development efforts to improve safe- guards technology. We made our review in response to a congressional directive contained in the Nuclear Non-Proliferation Act of 1978 (P.L. 95-242). This act requires us to study and report to the Congress by March 1981 on the implemen- tation and impact of the act on U.S. non-proliferation policies , purposes, and objectives.
