[1P05] Research on Dynamic PRA methodology considering dependencies of Multi-unit nuclear power plant

*Kakeru Asano1, Akira Yamaguchi1, Sunghyon Jang1 (1. Univ. of Tokyo)

Keywords:Probabilistic Risk Assessment, Dynamic PRA, Multi-unit site, CMMC method

As seen in Fukushima Daiichi accident, accident in Multi-unit site have interaction between units. Accident scenario would be changed by this interaction. In this research, the authors analyzed Fukushima report and made classification of Multi-unit dependencies. Also, the authors developed Multi-unit PRA methodology using Continuous Markov chain Monte Carlo method.
