In the tsunami PRA, especially for the nuclear power plant whose tsunami risk is high, it is possible that partial damage of the building wall due to tsunami wave pressure which would lead to the tsunami inundation into the building. In order to consider above effects on the realistic indoor inundation analysis, we have proposed evaluation method of the leakage flow through the building wall induced by inundated tsunami wave pressure.
