Nuclear power plants are large-scale complicated structures comprising many components. The connections between these components are one of the weakest parts of a nuclear power plant. Further, these parts retain many unknown characteristics with respect to the dynamic properties of the connections. To apply a 3D virtual plant vibration simulator to the large-scale structural analysis of a nuclear power plant, a technology to consider the structure as an assemblage of components and to enable whole scale analysis of an extra-large plant by considering the interaction between its parts was developed and implemented on a prototype system on a grid environment. In this report, a system construction on a grid environment of an assembly structure is analyzed; further, an example of an application for the static structure analysis of a cooling system of a high temperature engineering test reactor (HTTR) of The Oarai Research and Development Center, JAEA is shown.
