In this report, an example of improvement of fault displacement hazard evaluation position is described in an improvement of fault displacement PRA method and application to a virtual plant. We show the way of inverse analytical method of the fault displacement hazard defined on the ground surface to the seismic base through the fault displacement transfer model. In addition, this model proposed a concept to consider as a fault displacement ground transfer model from the seismic base to the reactor building foundation, etc. in the building / equipment fragility evaluation.
