Probabilistic Risk Assessment

The Noto Peninsula earthquake of 2024 caused several transformers to fail at the Shika Nuclear Power Plant. The impact of this on nuclear safety risk was quantitatively evaluated using the PRA method. In addition, the importance of each transformer was evaluated using the seismic PRA method to contribute to RIDM for seismic reinforcement of transformers.
