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.
