Abstract

The seismic probabilistic safety assessment consists of five phases. In the seismic hazard analysis the seismicity of the plant site is quantified. In the second phase, the structural response of plant buildings is evaluated. On the basis of structural response, the seismic fragilities of selected plant components are developed. In the following phase, the plant logic in the form of fault trees and event trees is established. In the last step, quantification of the core damage risk on the basis of the above information is carried out. For the median value of the annual core damage frequency,.
