Seismic response and fragility evaluation for an Eastern US NPP including soil-structure Interaction effects

摘要

The paper discusses methodological aspects involved in a probabilistic seismic soil- structure interaction (SSI) analysis for a Seismic Probabilistic Risk Assessment (SPRA) review. Am example of an Eastern US nuclear power plant (NPP) is presented. The approach presented herein follows the current practice of the Individual Plant Examination for external Events (IPEEE) program in the US. The NPP is founded on A relatively soft soil deposit, an thus the SSI effects on seismic responses are Significant.
