Our goal is to evaluate the validity of results obtained from seismic simulation of entire nuclear plant, and then to estimate real behavior. In this study, we have established a trial tool to enable a zooming analysis from a combining analysis of ground-building-equipments (beam model) to an assembly structural analysis of equipments (solid model) in order to compare results of beam model and solid model. By applying the tool to analysis of a cantilever model with various cross sections, we have confirmed that results of solid model well coincide with theoretical solutions and results of beam model.

Flow phenomena in a nuclear power plant (NPP) under an earthquake have an important role on behaviors of the NPP. We are developing three-dimensional virtual plant vibration simulator equipped with fluid-structure interaction analysis capability using Immersed Boundary Method. In the present study, we have adopted the method to flow analysis around a circular cylinder in order to verify the present method. Additionally, we propose the design to couple flow analysis to structural analysis using FEM on the three-dimensional virtual plant vibration simulator.
