We have developed a new index, called the resilience index, that evaluates the dynamic stability of the system safety of a nuclear power plant during a severe accident by considering the ability to recover system safety functions that have become lost in the situation. In this paper, a detailed evaluation procedure for the resilience index is described. The system safety of a PWR plant during a severe accident is then assessed according to the resilience index in order to discuss the applicability of ...

In Japanese BWR utilities, silicone rubber(VMQ) or fluoro rubber(FKM) has been used as a sealing material for the PCV upper flange and so on. However, these materials are not suitable for such use under the combined conditions of high-temperature steam and high-radiation dose by severe accident, so there is a possibility to reduce the sealing function that leads to a PCV flange leakage. Therefore, in the BWR plant owners recently decided to adopt an “improved EPDM“ which has excellent characteristics ...
