RIZZO Associates is reevaluating the Structures, Systems and Components (SSCs) for seismic fragilities at the Leibstadt NPP. The Site seismic hazard (PEGASOS) shows that the SSE type ground motion differs from the design basis ground motion, particularly in the high frequency range. Accordingly, the seismic fragility analysis was directed to improve SSC performance estimates so that the plant risk is not overstated. It is supported
