Tokai reprocessing plant (TRP) has been processing over 1,123 tons of spent fuels from the beginning of its active operation in Sept. 1977. For 30 years operation of TRP, many technological problems have been overcome to obtain the stable and reliable operation. The process for establishments of maintenance technology in TRP was evaluated through the analysis of significant plant equipment failures reported to the authorities concerned. Through these troubles and its solution, following knowledge could be obtained.

Times Cited Count：4 Percentile：29.44(Nuclear Science & Technology)The application of safeguards to the Tokai Reprocessing Plant(TRP), the world's first reprocessing plant with a sole objective of commercial use, was made on try and error basis because it was the first experience for both the plant and the inspection sides. Through thirty years' faithful cooperation to the IAEA-initiated safeguards program, TRP contributed also to the developments of the international credibility upon the concept of safeguards system of Reprocessing plant in non-nuclear weapon countries. TRP also has been processing over 1,123 ton of spent fuels from the beginning of its active operation in Sept.'77. For 30 years operation of TRP, many technological problems have been overcome to obtain the stable and reliable operation. The process for establishments of maintenance technology in TRP was evaluated through the analysis of significant plant equipment failures reported to the Government and so on. Discussion in this paper is also emphasized that the safeguards system and the maintenance technologies developed by TRP have been applied to the first Rokkasho commercial reprocessing plant (RRP). Furthermore, this operation knowledge base can contribute to the design and construction of the next generation reprocessing plant.

This paper describes the role of Tokai Reprocessing Plant (TRP) for the safeguards (SG) technology development by Japan and IAEA and its application to the first large commercial plant in Japan. Through several negotiations between Japan and USA, TRP accepted the full scope application of IAEA's SG, the development of U-Pu mixed conversion process, and the experimental work of IAEA for development of SG activities. Results under the TASTEX, which was research and development program by an agreement made during Japan and USA negotiation on reprocessing, were reflected to the INFCE, which was organized by the change in US atomic energy policy. Most of the current SG technologies being applied by IAEA were developed at this time. Both effectiveness and reliability of such technologies have been validated extensively through the 30 years operation of TRP.

This paper is compiled as a record of oral presentation by O.YAMAMURA at RECOD' 91 in April 15. 1991 in Sendai Japan with more than 600 attendance. It contains a proceeding, a manuscript of oral presentation and a manuscript of viewgraphs. The abstract of presentation is as belows. Since the start of construction of the Tokai Reprocessing Plant (TRP) in 1971, large efforts were taken by the Power Reactor and Nuclear Fuel Development Corporation (PNC) and various organizations to root the LWR fuel reprocessing technology in Japan. These efforts produced many achievements around the TRP, and now the future plan for the TRP is being studied.

Energy demand is increasing rapidly in the Asian-Pacific region. From the viewpoint of preventing global warming, countries in the region are expected to introduce more nuclear power plants (NPPs) which do not emit green house gases. The spent fuels from the NPPs should be reprocessed and fabricated into MOX fuel to decrease the amounts of radioactive wastes and future fuel recycling should be supported in the ARRC under the international regulation.
