A Fire Probabilistic Safety Assessment-called the Fire PSA-is being carried out by the French Institute of Nuclear Safety and Pro- tection (IPSN) to be used in the framework of the safety assessment of operating 900 Mwe PWRs. The aim of this study is to evaluate the core damage conditional probability which could results form a fire. A fire can induce unavailability of safety equipment, notably damaging electrical cables introducing a significant risk contributor. The purpose of this paper is to present the electrical cable fire tests Carried out by IPSN to identify the failure modes and to determine The cable damage criteria.
