Seismic Response Estimation of a Nuclear Power Plant Structure Considering Nearby Fault Based on a Multiscale Approach
Abstract eng: An approach to estimate the response of a model of nuclear power plant (NPP) that includes the rupture of a nearby fault using a multiscale approach is demonstrated. The conceptual model is the fault-structure system: a system that models the 3D fault rupture process, wave propagation through the irregular crust structure, effect of local geologic setting at the NPP location, and response of NPP structure. A multiscale method, called MacroMicro Analysis is employed, which resulted to reduction in computation cost. A reproduction of a recent earthquake event in Kanto region is performed to check the earthquake wave propagation and compare the resulting synthetic seismogram to the recorded seismogram in an observation station. A scenario earthquake simulation is then conducted and the response of NPP under this scenario is obtained. Results have revealed irregular structure deformation caused by the varying phase and amplitude characteristics of the input wave caused by the scenario earthquake.
