| PLANT DECLARED HPCI INOPERABLE DUE TO THE LOSS OF THE EMERGENCY SERVICE |
| WATER TO ONE OF TWO VENTILATION UNITS. |
| |
| THE EMERGENCY SERVICE WATER WAS LOST AS A RESULT OF THE FAILURE OF #13 |
| EMERGENCY SERVICE WATER PUMP TO START, WHICH PUT HPCI OUT OF SERVICE AND |
| THE PLANT IN A 24 HR TO SHUTDOWN LCO ACTION STATEMENT. WHEN THEY ATTEMPTED |
| TO START #13 EMERGENCY SERVICE WATER PUMP, THE MOTOR WOULD HUM BUT THE |
| IMPELLER WOULD NOT TURN AND THAT RESULTED IN THE TRIP OF THE PUMP BREAKER. |
| THEY MANUALLY TRIED TO TURN THE IMPELLER , WHICH SEEMED STUCK INITIALLY, BUT |
| THEY FINALLY GOT IT TO TURN FREELY. THERE MAY HAVE BEEN SOME TYPE OF |
| DEBRIS THAT WAS CAUSING THE IMPELLER NOT TO TURN. CURRENTLY THEY ARE |
| PERFORMING OPERABILITY CHECKS ON THE PUMP SO THAT THE LCO CAN BE EXITED. |
| DURING THIS EVENT THE NORMAL SERVICE WATER WAS AVAILABLE. |
| |
| THE RESIDENT INSPECTOR WAS NOTIFIED. |

| MANUAL REACTOR TRIP DUE TO ROD CONTROL URGENT FAILURE ALARM |
| |
| During a planned plant shutdown, with the reactor already subcritical, |
| control bank 'A' group 2 did not move as rods were being inserted. As a |
| result, the rod control system received an "Urgent Alarm" which inhibited |
| manual control rod motion. The licensee performed a manual trip and all |
| rods fully inserted. The problem is being investigated. |
| |
| Heat removal was and is by steam dump to the main condenser with feedwater |
| from the main feedwater system. |
| |
| The licensee notified the NRC Resident Inspector. |

| THE CONTROL ROOM EMERGENCY VENTILATION FAN SUCTION SUPPLY DAMPER SWITCH |
| FOUND IN THE INCORRECT POSITION. |
| |
| THE CONTROL ROOM EMERGENCY FAN, "1-HV-F-42", SUCTION SUPPLY DAMPER SWITCH |
| WAS FOUND IN THE "NORMAL MODE" POSITION INSTEAD OF THE "LOCKOUT" POSITION. |
| THE SWITCH HAS TO BE IN THE "LOCKOUT" POSITION TO MAINTAIN THE CONTROL ROOM |
| PRESSURE ENVELOPE IN THE RECIRCULATION MODE DURING THE INITIAL STAGES OF A |
| FUEL HANDLING ACCIDENT OR SAFETY INJECTION. BY THE SWITCH BEING IN THE |
| INCORRECT POSITION(NORMAL MODE) IT WOULD HAVE AFFECTED THE ABILITY OF THE |
| FAN TO PERFORM ITS ACCIDENT FUNCTION. THE PLANT ENTERED A 7 DAY LCO UNDER |
| TS 3.7.7.1 WHICH REQUIRES CORRECTIVE MEASURES TO BE IMPLEMENTED. THE SWITCH |
| WAS PLACED IN THE CORRECT, "LOCKOUT", POSITION AT 10:32 AM. INVESTIGATION |
| ON HOW THE SWITCH GOT INTO THE INCORRECT POSITION IS ONGOING. |

| THE PLANT SHIFT SUPERINTENDENT(PSS) WAS NOTIFIED THAT THERE HAD BEEN A |
| FAILURE OF THE UF6 RELEASE DETECTION SYSTEM IN THE C-333 PROCESS BUILDING |
| UNIT 5 CELL 4. THE FAILURE OCCURRED DURING THE TWICE-PER-SHIFT TSR |
| SURVEILLANCE WHICH REQUIRES "TEST FIRING" OF THE DETECTOR HEADS. THE PSS |
| IMMEDIATELY DECLARED THE SAFETY SYSTEM INOPERABLE AND DIRECTED THE |
| IMPLEMENTATION OF TSR-REQUIRED ACTIONS WHICH INCLUDE PLACING A "SMOKE WATCH" |
| IN THE AFFECTED AREA. IN ADDITION, THE OPERATING PRESSURE OF THE AFFECTED |
| EQUIPMENT WAS REDUCED TO BELOW ATMOSPHERIC PRESSURE WHICH PLACED THE |
| EQUIPMENT IN A MODE IN WHICH THE SAFETY SYSTEM WAS NOT REQUIRED TO BE |
| AVAILABLE AND OPERABLE. THE PSS WAS SUBSEQUENTLY NOTIFIED (AT 0130 ON |
| 4/12/99) THAT THE EQUIPMENT HAD ACTUALLY FAILED DURING THE TEST AT |
| APPROXIMATELY 2145. COMPENSATORY ACTIONS WERE NOT IMPLEMENTED IN A TIMELY |
| MANNER IN ACCORDANCE WITH THE APPLICABLE TSR. THE TSR-REQUIRED ACTIONS WERE |
| REQUIRED TO BE IMPLEMENTED WITHIN 1 HOUR AND WERE IMPLEMENTED APPROXIMATELY |
| 80 MINUTES LATE. |
| |
| THIS EVENT IS BEING SUBMITTED LATE DUE TO A MISINTERPRETATION OF THE EVENT |
| REPORTING CRITERIA. |

| PLANT HAD AUTO START AND LOADING OF THE EMERGENCY DIESEL "B". |
| |
| THE PLANT IS IN MODE 5 FOR A REFUELING OUTAGE AND PERSONNEL WERE PERFORMING |
| A SAFETY INJECTION FUNCTIONAL TEST. THIS TEST REQUIRES THE EMERGENCY DIESEL |
| "B" TO BE PLACED IN LOCKOUT WHILE DEENERGIZING THE SAFEGUARDS BUSES. UPON |
| COMPLETION OF THIS PORTION OF THE TEST, BUS RESTORATION WAS INITIATED. THE |
| RESTORATION STEPS REQUIRE CLOSURE OF BUS 17 (SCREENHOUSE SAFEGUARDS BUS) |
| NORMAL FEEDER BREAKER, BUT IT WOULD NOT CLOSE. RESTORATION CONTINUED WHILE |
| TROUBLESHOOTING THE BUS 17 NORMAL FEEDER BREAKER PROBLEM. WHEN THE STEPS |
| FOR DIESEL GENERATOR "B" WERE PERFORMED, THE DIESEL WAS RESET. UPON RESET, |
| THE DIESEL GENERATOR "B" SAW THE UNDERVOLTAGE ON BUS 17, AUTO STARTED AND |
| LOADED BUS 17 AS DESIGNED. THE DIESEL GENERATOR "B" WAS SECURED AT 1631 AND |
| BUS 17 HAS BEEN REENERGIZED FROM NORMAL POWER SUPPLY. INITIAL |
| INVESTIGATION SHOWED CAUSE OF THE FAILURE OF THE FEEDER BREAKER TO CLOSE WAS |
| DUE TO A BLOWN UNDERVOLTAGE FUSE. |

| - RCIC SYSTEM DECLARED INOPERABLE DUE TO FAILED SYSTEM COOLING VALVE DURING |
| A TEST - |
| |
| AT 0128 CDT ON 04/14/99, THE LICENSEE DECLARED THE REACTOR CORE ISOLATION |
| COOLING (RCIC) SYSTEM INOPERABLE DUE TO THE FAILURE OF THE RCIC SYSTEM |
| COOLING VALVE, #RCIC-MO-132. WHEN THE VALVE CONTROL SWITCH WAS PLACED IN |
| THE CLOSE POSITION IN ORDER TO RECORD THE VALVE STROKE TIME DURING THE RCIC |
| POWER OPERATED VALVE OPERABILITY SURVEILLANCE TEST, THE VALVE MOVED TO THE |
| INTERMEDIATE POSITION AND STOPPED. STATION OPERATORS VERIFIED THAT THE |
| VALVE WAS NOT CLOSED AND ISOLATED THE RCIC SYSTEM STEAM SUPPLY AND SUCTION |
| AND DISCHARGE PATHS IN ORDER TO PREVENT SYSTEM INITIATION, EVIDENCE |
| PRESERVATION, AND EXCESSIVE CYCLING OF THE BAROMETRIC CONDENSER PUMP. |
| STATION OPERATORS ALSO VERIFIED THAT THE HIGH PRESSURE COOLANT INJECTION |
| SYSTEM WAS OPERABLE. |
| |
| TECH SPEC LCO A/S 3.5.3.A REQUIRES THE LICENSE TO RESTORE THE RCIC SYSTEM TO |
| OPERABLE STATUS WITHIN 14 DAYS OR SHUT THE PLANT DOWN. |
| |
| STATION OPERATORS ARE INVESTIGATING THE CAUSE OF THE VALVE FAILURE AND PLAN |
| TO REPAIR THE VALVE. |
| |
| THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR. |
