10 CFR SECTION: CDEG  21.21(c)(3)(i)      DEFECTS/NONCOMPLIANCE



10 CFR PART 21 NOTIFICATION - WESTINGHOUSE ELECTRIC CORPORATION  

HAS IDENTIFIED DEFECTS THAT COULD CREATE A SUBSTANTIAL SAFETY    

HAZARD SHOULD THEY REMAIN UNCORRECTED.                           

                                                                 

DEVIATIONS WERE IDENTIFIED BY WESTINGHOUSE DURING A LESSONS      

LEARNED REVIEW OF A PILOT PROGRAM TO PROVIDE SAFETY-RELATED      

CIRCUIT BREAKER REFURBISHMENT FOR THE BYRON AND BRAIDWOOD

NUCLEAR

SITES.  THIS PILOT PROGRAM, WHICH WAS CONDUCTED AT WESTINGHOUSE  

SATELLITE FACILITIES, INCLUDED BOTH WESTINGHOUSE TYPE 'DHP'      

SERIES AND 'DS' SERIES BREAKERS.  IT WAS DISCOVERED THAT CORRECT 

PROCEDURES WERE NOT UTILIZED, RESULTING IN CERTAIN TESTS AND     

INSPECTIONS NOT BEING PERFORMED OR DOCUMENTED.  THE ITEMS WHICH  

WERE OMITTED OR NOT DOCUMENTED INCLUDED THE PERFORMANCE OF

TIMING

TESTS, CONTACT RESISTANCE CHECKS TO CORRECT VALUES, REAPPLICATION

OF LUBRICANT, OPENING FORCE MARGIN VERIFICATION, AND WELD        

INSPECTIONS.  THESE TESTS AND INSPECTIONS ARE DESIGNED TO PROVIDE

ASSURANCE THAT BREAKER OPERATION (EITHER TO OPEN OR CLOSE) WILL  

BE SUCCESSFULLY COMPLETED.  WESTINGHOUSE DETERMINED THAT THE     

TESTS THAT WERE PERFORMED ON THE REFURBISHED BREAKERS BEFORE     

THEIR RETURN TO BYRON AND BRAIDWOOD WERE INSUFFICIENT TO         

REESTABLISH FULL QUALIFICATION OF THE BREAKERS.  ALL BREAKERS    

THAT WERE REFURBISHED USING INCORRECT PROCEDURES HAVE BEEN       

IDENTIFIED.
