- 10CFR21 REPORT OF DEFECTIVE T-DRAINS ON ENVIRONMENTALLY
QUALIFIED MOVs -
INDIAN POINT UNIT 2 IS IN MODE 5 (COLD SHUTDOWN) IN A MAINTENANCE
OUTAGE.
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.
