A framework for analyzing nuclear power multiunit accident scenarios and providing accident mitigation and site improvement suggestions

During the Fukushima Daiichi and Daini accidents, the interactions of multiple units at the same site made accident mitigation more difficult compared to single unit sites. The accidents revealed important multiunit risk sources that are not identified by risk assessments for single-unit sites. Therefore, it's important to obtain an integrated risk evaluation for multiunit sites. However, multiunit accident scenarios are difficult to analyze due to the complexity of multiunit interactions. In the work reported here, a framework capable of analyzing multiunit accident scenarios involving inter-unit interactions is presented. Our framework provides a structured method to analyze accident propagation events, which are not being studied much currently. In addition, our framework is capable of providing accident mitigation and site improvement suggestions that can help improve site safety.
