東海再処理工場がこれまで約30年間に経験してきたトラブル事象を分析し、保守技術開発の観点から有用な知見が得られた機器故障に焦点を絞って、復旧の過程を解析,再処理施設の保守技術の特徴と開発成果,将来プラントに活かすべき経験等について報告する。

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.
