STURY SBO ACCIDENT OF TYPICAL M310 NPP WITH PROBABILISTIC RISK ASSESSMENT METHOD
The availability of alternating current (ac) electrical power is essential for the safe operation and accident recovery of commercial nuclear power plants (NPPs). And reliable off-site power is one key to minimizing the probability of severe accidents.1,2 This paper mainly issues the risk of SBO resulting from Loss Of Offsite Power (LOOP) on the typical M310 type stations (3-Loops,1000MWe, pressurized NPP) of China during full power operation and normal shutdown/RHR states with constructing SBO event trees and fault trees, and Human Reliability Analysis (HRA) and data analysis are also taken into account in this analysis. Further more, Based on these work, the Core Damage Frequency (CDF) values and associated Minimal Cut Sets (MCSs) are gained. The results from the analysis give us some useful information that can help to find the weaknesses of NPP design or operation and to improve the safety level of NPPs operation.
