WHILE PREPARING TO INSTALL A SPARE MOTOR ON ENVIRONMENTALLY QUALIFIED (EQ) MOTOR OPERATED VALVE (MOV) #MOV-856D, THE LICENSEE DISCOVERED THAT THE MOV HAD A DEFECTIVE T-DRAIN. IN ORDER FOR AN EQ MOV TO BE OPERABLE, THE VALVE MUST HAVE A T-DRAIN INSTALLED TO RELIEVE MOISTURE BUILDUP IN A HARSH ENVIRONMENT FOLLOWING A MAJOR ACCIDENT. THE T-DRAIN, SUPPLIED BY LIMITORQUE, INC, LYNCHBURG, VA, WAS NOT DRILLED THROUGH AND WOULD ACT AS A PIPE PLUG RATHER THAN AS A PIPE DRAIN. THE LICENSEE OBSERVED THIS CONDITION TO BE AN APPARENT MANUFACTURER'S DEFECT. THE SPARE MOTOR HAD BEEN REMOVED FROM THE SPARE ACTUATOR FOR #MOV-536 WHICH HAD BEEN REMOVED FROM SERVICE IN 1993, REBUILT, AND STORED FOR FUTURE USE. THE LICENSEE INSPECTED ALL EQ MOVs AND FOUND SEVERAL WITH A SIMILAR DEFECTIVE T-DRAIN. THE LICENSEE HAS REMOVED ALL DEFECTIVE T-DRAINS AND INSTALLED PROPERLY DRILLED T-DRAINS ON ALL EQ MOVs. THE LICENSEE PLANS TO PREPARE A WRITTEN REPORT OF THIS CONDITION AND SUBMIT IT TO THE NRC PER 10CFR21.21. THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR.
