Abstract

NPP Goesgen completed its first PRA (Level 1 and 2, shutdown, external and internal events) in 1994 in close cooperation with PLG (now ABS Consulting). During the review process by the regulatory authority completed in 1999 it was understood, that the methodology and the scope of the seismic PRA should be expanded. In 2001, a completely revised and updated seismic PRA was submitted to the regulatory authority. Experience gained from this update indicated that further improvements in the methodology are necessary. Insights gained and recommendations for further improvements of the methodology are presented in the paper.
