This report presents the activities performed in the frame of LP1, Objective B (Accident consequences evaluation), task B3 of PAR 2014, ADP ENEA-MSE. The study addresses the safety assessment of nuclear power plants due to external events, adopting a risk informed approach. To this aim safety analysis is thus implemented with the evaluation of some specific probabilistic aspects, related e.g. to the multi-unit risk issue, as a complement to traditional deterministic investigations. To complement the hazard assessment, a deterministic investigation of an existing plant has been carried out. In doing that aging effects, as a consequence of loadings originated by the multiple accident event, have been considered in order to highlight possibly vulnerability.

Abstract

This report presents the activities performed in the frame of LP1, Objective B (Accident consequences evaluation), task B3 of PAR 2014, ADP ENEA-MSE. The study addresses the safety assessment of nuclear power plants due to external events, adopting a risk informed approach. To this aim safety analysis is thus implemented with the evaluation of some specific probabilistic aspects, related e.g. to the multi-unit risk issue, as a complement to traditional deterministic investigations. To complement the hazard assessment, a deterministic investigation of an existing plant has been carried out. In doing that aging effects, as a consequence of loadings originated by the multiple accident event, have been considered in order to highlight possibly vulnerability.
