In regard to the risk assessment of nuclear power plant to fault displacement, we have accumulated knowledge related to the assessment of reactor building and equipment and piping systems (control rod insertability, equipment inside building, crossover piping between buildings). In this presentation, we will report the realistic evaluation results of the entire piping system including support and anchorage (specifying damage mode, clarifying critical part, advanced analysis method, etc.) as an advanced analysis evaluation.
