| TWO CRITICALITY ALARM HORNS FAILED TO SOUND DURING TESTING |
| |
| "At 1030 on 2-2-01 the PSS was informed that the two Criticality Accident |
| Alarm System (CAAS) pneumatic horns for building C-337-A failed to sound |
| properly during testing. The system is required to be operable according to |
| TSR 2.4.4.3.b for the prescribed modes of operation. Even though the system |
| was declared inoperable at the time of the failure it is possible that the |
| system would not have performed its intended safety function had it been |
| required prior to being declared inoperable. The two horns were replaced and |
| satisfactorily tested. |
| |
| "This event is reportable under 10 CFR 76.120(c)(2) as an event in which |
| equipment required by the TSR is disabled or fails to function as |
| designed." |
| |
| The NRC resident inspector has been informed of this event. |

EVENT TEXT
+------------------------------------------------------------------------------+
| UNUSUAL EVENT DECLARED DUE TO FIRE LASTING MORE THAN 15 MINUTES |
| |
| The plant was in the process of raising power after exiting shutdown |
| operations and were at 39% power when a non-class 1E breaker failed at 1514 |
| PST causing a loss of power to a non-safety electrical bus. This in turn |
| caused the loss of some secondary plant equipment which led to the loss of |
| condenser vacuum, condensate pumps, feedwater pumps, and other equipment |
| leading to a trip of the plant. The breaker failure resulted in a fire |
| which lasted until 1544 PST and the Unusual Event was declared at 1527 PST. |
| The plant also lost all the control room annunciators for a period of time, |
| they have been recovered. The plant is stable in Hot Standby with the |
| reactor coolant pumps running, auxiliary feedwater supplying the steam |
| generators, and excess heat being released through the steam generator |
| atmospheric dumps. The main steam isolation valves are closed as a result |
| of the secondary equipment that was lost. The emergency diesel generators |
| were running unloaded on automatic start signal from the loss of the |
| non-class 1E bus. Electrical power continues to be provided to all safety |
| busses and the unaffected parts of the non-safety busses from offsite |
| power. |
| |
| The licensee notified the NRC Resident Inspector and state and local |
| authorities. |
| |
| * * * UPDATE AT 1956 EST ON 02/03/01 BY BOB CONOSCENTI TO FANGIE JONES * * |
| * |
| |
| The licensee has determined that one breaker failed catastrophically causing |
| the loss of one 4160 VAC bus and pieces of the breaker assembly caused |
| grounds in another 480 VAC bus causing its loss. The plant is stable in Hot |
| Standby. The licensee notified the NRC Resident Inspector. The Unusual |
| Event was terminated at 1544 PST. |
| |
| The R4DO (Blair Spitzberg), NRR EO (Richard Wessman), IRO Manager (Charles |
| Miller), and FEMA (Gene Nupp) have been notified. |

| AUTOMATIC TURBINE TRIP/REACTOR SCRAM DURING TESTING |
| |
| During performance or routine turbine valve testing, an automatic turbine |
| trip and subsequent reactor scram occurred due to low turbine emergency trip |
| system pressure. The unit is currently stable in Condition 3 (Hot Shutdown) |
| with reactor vessel water level being maintained by the motor driven |
| feedwater pump and reactor pressure being controlled via the steam bypass |
| valves to the main condenser. All systems functioned as expected. |
| |
| The NRC resident inspector has been informed of this event by the licensee. |

| DISCOVERY OF VALVE CLOSED THAT COULD AFFECT ACCIDENT MITIGATION |
| |
| "While performing troubleshooting operation on the Unit 1 Crossover Steam |
| Dump System an Instrument Air Valve was discovered to be closed, when it |
| should have been open. This closed valve (IA-1553) isolates Instrument Air |
| to the Crossover Steam Dump Valves rendering the system inoperable. This |
| system is required to be operable by the FSAR Appendix T and Power must be |
| <437 MWe if the system is inop. At the time of discovery power was <437 |
| MWe, however initial investigation leads to the conclusion that this valve |
| has probably been closed since October, 2000. Since Crossover Steam Dumps |
| provide protection for a Turbine Overspeed Accident and is part of the PBNP |
| Design Basis it was conservatively decided to make this 8-hour report. Unit |
| 1 will remain < 437 MWe until the system is fully restored and tested. An |
| investigation is continuing." |
| |
| The licensee notified the NRC Resident Inspector. |
