| The licensee reported that an M67 Mortar Sight Device was lost in December   |
| 2000 at Ft. Polk, LA during a training exercise for the 2nd Armored Cavalry. |
| The device contains multiple Tritium sources with an aggregate activity of   |
| 5.8 Curies.  The licensee does not believe the device was inadvertently sent |
| to the landfill, however, there are no specific plans to attempt recovery.   |
| The training area is restricted and inaccessible to the general public.      |

| "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.                                                       |

| 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 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.                                            |

| 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.            |
|                                                                              |

| 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."                                                |
