Safeguards improvement for the Tokai Reprocessing Plant (TRP)

Safeguards have been implemented at TRP with cooperation between the Government of Japan and the IAEA. JAEA has actively cooperated with the safeguards activities, and has also tackled the development of safeguards technology for the TRP under the Japan Support Programme for Agency Safeguards (JASPAS) and a cooperation research program with Department of Energy (DOE). IAEA has established new policies in order to improve the strengthening and the efficiency of the IAEA's safeguards in 1993. As a result the IAEA requested the Safeguards Improvement Plan for TRP in 1995. The main improvement areas were: improvement of verification for design information; improvement of reliability of verification for primary tanks; establishment of waste verification methods; and improvement of evaluation methods for material accountancy. JAEA had actively cooperated in these improvement items on the basis of the regular discussion and consultations among three parties. This paper will report the accomplishments for the improvement plan. (author)
