THE LICENSEE RECEIVED A WESTINGHOUSE DB-25 CIRCUIT BREAKER REFURBISHED IN 1992 BY WESTINGHOUSE REPLACEMENT COMPONENTS SERVICES, MONROEVILLE, PA. THE REFURBISHED DB-25 CIRCUIT BREAKER WAS RETURNED TO GINNA WITH A MISSING PIN IN THE OPERATING MECHANISM. THE ABSENCE OF THIS PIN IS BELIEVED TO HAVE CONTRIBUTED TO THE FAILURE OF THE "SWP1B" CIRCUIT BREAKER TO CLOSE ON A MANUAL SIGNAL FROM THE MAIN CONTROL BOARD. THIS IMPLIES THAT THE POTENTIAL EXISTS FOR THE BREAKER NOT TO CLOSE ON AN AUTOMATIC DEMAND AND THEREFORE NOT BE AVAILABLE TO PERFORM ITS SAFETY FUNCTIONS. THERE ARE 41 PERMANENTLY INSTALLED DB-25 BREAKERS IN THE SCREEN HOUSE AND TURBINE BUILDINGS AT GINNA. ALL OF THE REMAINING BREAKERS WERE VISUALLY INSPECTED TO VERIFY THE PIN IN QUESTION WAS INSTALLED. NO OTHER BREAKERS WERE FOUND TO BE MISSING THE PIN. THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR.
