Performance-goal based (risk informed) approach for establishing the SSE site specific response spectrum for future nuclear power plants

In addition to more thoroughly documenting the basis for the ASCE 43-05 performance-goal based approach, the paper also summarizes the minimum seismic core damage frequency (SCDF) achieved at 28 Central and Eastern U.S. sites when the SSRS is defined by this approach coupled with other NRC requirements. The minimum SCDF lies in the range of less than 6 × 10−6/yr to 0.6 × 10−6/yr with a median ratio of about 3 × 10−6/yr.
