| 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. |
| |
| * * * UPDATED AT 0016 EDT ON 8/4/2001 BY SCOTT WHITSON TO FANGIE JONES * * |
| * |
| |
| 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. |
| |
| * * * UPDATED AT 0115 EDT ON 8/4/2001 BY DENNIS CARLSON TO FANGIE JONES * * |
| * |
| |
| 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 R3DO (John Madera), NRR EO (Herb Berkow), and FEMA (Zapata) have been |
| notified. |
| |
| * * * UPDATED AT 0325 EDT ON 8/4/2001 BY MIKE SLEIGH TO FANGIE JONES * * * |
| |
| 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. |
| |
| The licensee notified the NRC Resident Inspector and intends to notify R3 |
| IAT (James Creed). The R3DO (John Madera) was notified. |
| |
| Refer to the HOO Log for details. |

| AUTOMATIC START OF BOTH UNITS DIESEL GENERATORS DUE TO A LOSS OF START-UP |
| POWER |
| |
| "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. |
| |
| None of the diesel generators loaded and all have been secured and returned |
| to standby. |
| |
| The licensee informed the NRC resident inspector. |
