Literature survey on probabilistic safety study

Kitahara, Yoshihisa*

Probabilistic safety study has extensively been developed for nuclear energy use with the basic techniques of probabilistic safety assessment(PSA) or Probabilistic Risk Assessment (PRA) which is now indispensatle especially for nuclear reactor safety and particularly with respect to the evaluation of severe accidents and to the achievement of safety goal. In the field of non-reactor fuel cycle facilities, however, there is at the present moment very limited application of PSA. This report su㎜arizes several papers related to probabilistic safety study on nuclear fuel cycle facilities given, as basic data for safety study of facilities such as reprocessing and plutonium fuel fabrication facilities in Tokai Works. Contents consist of classification and su㎜arization of about 60 papers in addition to comments related to the safety study of the Tokai facilities.
