Recently GL 89-10 static and dynamic Motor-Operated Valve (MOV) tests are being performed in Korean nuclear power plants to ensure MOV operability in design basis condition. And GL 96-05 MOV periodic verification testing will be followed after GL 89-10 testing. MOV risk importance categorization will be incorporated in Korean MOV periodic testing program for effective MOV test. In this study, MOVs were preliminarily categorized based on risk importance measures FV and RAW using level 1 internal event PSA. Configuration effect and importance uncertainty effect to risk importance of MOVs were also investigated. (authors)
