Abstract

This paper initiates a study focused on shutdown safety as well as Probability Safety Analysis(PSA) for shutdown operation at 1000 MW PWR.Shutdown PSA models considering different plant outage types are constructed respectively to evaluate the risk of LOI-RRA operation.The results show that the potential risk during shutdown should not be ignored;going through the LOI-RRA operation at cool shutdown refueling outage significantly increases the plant risk.
