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.
