Abstract

Abstract

In this paper,GO-FLOW method is applied to analyze the reliability of residual heat removal system at pressurized water reactor NPPs.The contribution to system unavailability caused by common cause failures is further calculated with β model,MGL model and α model.The results show that common cause failure has a significant effect on system reliability and GO-FLOW method can be effectively applied to system reliability analysis with common cause failures.
