THE ABSENCE OF THXS 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 ALSO IMPLIES THAT THE POTENTIAL EXISTS FOR THE BREAKER NOT TO CLOSE ON AN AUTOMATIC DEMAND AND THEREFORE NOT BE AVAXLABLE TO PERFORM XTS SAFETY FUNCTIONS. THERE ARE 41 PERMANENTLY XNSTALLED DB-25 BREAKERS IN THE SCREEN HOUSE AND TURBINE BUILDINGS AT THE SXTE. ALL OF THE REMAINXNG BREAKERS WERE VISUALLY INSPECTED TO VERIFY THE PIN IN QUESTION WAS INSTALLED. NO OTHER BREAKERS WERE FOUND TO BE MISSING THE PIN.
