| UNIT 1 DECLARED AN UNUSUAL EVENT DUE TO A FIRE LASTING GREATER THAN 10       |
| MINUTES                                                                      |

| A fire occurred in the 4KV Bus 12  while realigning the electrical power     |
| supplies from the 1 Reserve Transformer to the 1 Main Transformer during     |
| power ascension.  Bus 12 supplies both the 12 Reactor Coolant Pump and the   |
| 12 Feedwater Pump which were secured.  The 11 Reactor Coolant Pump was also  |
| secured placing the unit in natural circulation.  Auxiliary Feedwater Pumps  |
| 11 and 12 are in service (autostarted on lo-lo SG level) supplying both      |
| Steam Generators (SG) as normal for a reactor trip.  The Main Condenser is   |
| in-service for decay heat removal.                                           |
|                                                                              |
| The licensee is in the process of electrically isolating Bus 12.  The Red    |
| Wing Fire Department is onsite responding to the fire which has not been     |
| confirmed extinguished at the time of this report.                           |
|                                                                              |
| The cause of the reactor trip and the fire is unknown.                       |
|                                                                              |
| The licensee informed state/local agencies and the NRC resident inspector.   |
|                                                                              |

| The licensee reported that 2 employees were treated for heat exhaustion on   |
| site and another employee was transported to a local hospital at 2255 CDT    |
| for the same reason.  All were part of the onsite fire brigade.              |
|                                                                              |

| The licensee exited the Unusual Event at 0012 CDT on 8/4/2001.  The plant is |
| stable in natural circulation and all safeguards buses are energized  by     |
| offsite power.  The licensee notified the NRC Resident Inspector.            |

| The licensee reported that at the beginning of the Unusual Event a           |
| safeguards degradation related to the area boundary took place.              |
| Compensatory measures were taken upon discovery.                             |
|                                                                              |

| "Electrical fault caused loss of Start-up Power to both units.  This caused  |
| all six [6] diesel generators on both units to automatically start."         |
|                                                                              |
| Circuit breaker CB212 which supplies 230KV start-up power to both units      |
| opened due to an unidentified electrical fault.  Initial indication was a    |
| loss of power to outbuildings onsite followed about twenty-two (22) minutes  |
| later with a loss of power to the Start-up transformers.  Investigation      |
| found the grounding fuses on the Unit 1 side open.  Should a unit trip occur |
| while in this condition, RCS cooldown by natural circulation would be        |
| required.                                                                    |

| Both units are in Tech Spec LCO 3.8.1 Condition 'A' which requires           |
| restoration of start-up power within 72-hours or unit shutdown; mode 3 (hot  |
| standby) in the following 6-hours followed by mode 5 (cold shutdown)         |
| 36-hours later.  The licensee is performing a maintenance and engineering    |
| evaluation to determine if start-up can be restored by closing a cross-tie   |
| breaker from Unit 2.                                                         |
