- 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.
