SEISMIC PERFORMANCE ASSESSMENT OF NUCLEAR POWER PLANTS
Seismic assessments of a sample conventional and base-isolated nuclear power plant (NPP) are performed using a new procedure that builds on the methodology presented in the draft ATC-58 Guidelines and the widely used Zion method, which uses fragility curves defined in terms of ground-motion parameters. The new procedure improves the Zion method by using fragility curves that are defined in terms of structural response parameters since damage and failure of NPP components are more closely tied to structural response parameters than to ground motion parameters. The proposed performance assessment procedure is used to evaluate the mean annual probability of unacceptable performance of the sample NPP reactor buildings. The seismic performance assessment confirms the utility of seismic isolation at reducing seismic risk in NPPs.
