Seismic risk assessment as applied to a BWR
The seismic risk methodology developed in the U.S. NRC Seismic Safety Margins Research Program (SSMRP) was demonstrated by its application to the Zion nuclear power plant, a pressurized water reactor (PWR). A detailed model of Zion, including systems analysis models (initiating events, event trees, and fault trees), structure and SSI models, and piping models, was developed and analyzed. The basic SSMRP methodology can be applied to a boiling water reactor (BWR). To demonstrate its applicability, to identify fundamental differences in seismic risk between a PWR and a BWR, and to provide a basis of comparison of seismic risk between a PWR and a BWR when analyzed with comparable methodology and assumptions, a seismic risk assessment is being performed on the Lasalle nuclear power plant. This paper describes the seismic risk assessment methodology used to assess the Lasalle nuclear power plant.
