| HIGH PRESSURE COOLANT INJECTION (HPCI) DECLARED INOPERABLE |
| |
| HPCI OUTBOARD STEAM SUPPLY ISOLATION VALVE, MO 1-2301-5, WAS UNABLE TO BE |
| CLOSED USING THE CONTROL ROOM CONTROL SWITCH DURING A PLANNED VALVE TIMING |
| SURVEILLANCE PRIOR TO A PLANNED HPCI SYSTEM OUTAGE. PRIOR TO THIS, AT 2348 |
| CDT ON 10/4/99, THE HPCI SYSTEM WAS MADE INOPERABLE WHEN THE INBOARD STEAM |
| SUPPLY ISOLATION VALVE, MO 1-2301-4, WAS CLOSED AS PART OF THE VALVE TIMING |
| SURVEILLANCE TO ALLOW TESTING OF THE OUTBOARD VALVE. SINCE MO 1-2301-5 |
| COULD NOT BE CLOSED, MO 1-2301-4 WAS KEPT CLOSED TO COMPLY WITH TECHNICAL |
| SPECIFICATIONS 3.5.a ACTION STATEMENTS AND STATION PROCEDURES FOR AN |
| INOPERABLE CONTAINMENT ISOLATION VALVE. HPCI COULD NOT BE RETURNED TO |
| SERVICE, AS PLANNED, AND REMAINS INOPERABLE. ALL EMERGENCY CORE COOLING |
| SYSTEMS, EMERGENCY DIESEL GENERATORS, AND REACTOR CORE ISOLATION COOLING |
| SYSTEM ARE FULLY OPERABLE. |

| W2 SWITCH SUPPLIED BY WESTINGHOUSE DRAWN FROM STOCK DID NOT OPERATE |
| PROPERLY |
| AFTER BEING INSTALLED. |
| |
| W2 SWITCH WAS SUPPLIED TO ROCHESTER GAS AND ELECTRIC CORPORATION BY |
| WESTINGHOUSE ELECTRIC CORPORATION. A SAFETY RELATED W2 SWITCH DRAWN FROM |
| STOCK DID NOT OPERATE SATISFACTORILY AFTER BEING INSTALLED IN THE MAIN |
| CONTROL BOARD FOR USE AS THE CONTROL SWITCH FOR SAFETY INJECTION PUMP 1C |
| (1/SIP1 C2). THE SWITCH DID WORK PROPERLY BEFORE INSTALLATION IN THE MAIN |
| CONTROL BOARD POSITION. HOWEVER, SUBSEQUENT TO INSTALLATION THE SWITCH |
| MECHANISM WOULD BIND AND WOULD NOT SPRING RETURN TO THE "AFTER CLOSE" OR |
| "AFTER TRIP" POSITIONS. THE SWITCH IS EXPECTED TO FUNCTION PROPERLY IN BOTH |
| POSITIONS. |
| |
| THE SUBSTANTIAL SAFETY HAZARD CREATED BY THE SWITCH POTENTIALLY BEING STUCK |
| IN THE "TRIP" POSITION IS THAT THE ASSOCIATED ECCS PUMP BREAKER WOULD NOT |
| AUTO-CLOSE FOLLOWING A SAFETY INJECTION ACTUATION SYSTEM SIGNAL; THEREFORE, |
| THE ASSOCIATED ECCS PUMP WOULD NOT PERFORM ITS SAFETY FUNCTION. THE |
| POSTULATED FAILURE, IN CONJUNCTION WITH ANOTHER POSTULATED SINGLE FAILURE, |
| COULD CAUSE A LOSS OF SAFETY FUNCTION FOR THE ECCS SYSTEM. |

| HIGH PRESSURE COOLANT INJECTION (HPCI) DECLARED INOPERABLE. |
| |
| DURING DRILLING OPERATIONS TO INSTALL HILTI BOLTS IN THE HPCI ROOM, A WORKER |
| LEANED UP AGAINST AN OIL LINE AND CAUSED AN OIL LEAK. THE LEAK WAS |
| ESTIMATED WITH NO PRESSURE TO BE AT 60 DROPS PER MINUTE. HPCI WAS DECLARED |
| INOPERABLE PER TECHNICAL SPECIFICATION 3.5.E.2 (7 DAY LIMITING CONDITION OF |
| OPERATION) . ALL OTHER EMERGENCY CORE COOLING SYSTEMS, REACTOR CORE |
| ISOLATION COOLING (RCIC), AND THE EMERGENCY DIESEL GENERATORS ARE FULLY |
| OPERABLE. |
