再処理工場におけるトラブル事例の構造化表現に関する検討
概要
In this study, the generalized failure mechanism knowledge (GFMK) derived from trouble cases in the Rokkasho reprocessing plant has been applied to an mechanical subsystem in the same plant in order to examine its general applicability. This study confirms that the GFMK can be applied to the subsystem of a pool water cooling system and that a potential failure mechanism can be successfully derived. The efficacy of the derived knowledge regarding this failure mechanism was evaluated by referring to maintenance manual. The result has demonstrated that GFMK can point out the failure mechanism that have not been explicitly referred in the maintenance manual. It is expected that GMFK can contribute to proactively check possible failure events in a realistic scale system maintenance without depending on the field experiences.
