+------------------------------------------------------------------------------+
| LOSS OF NON-SAFETY RELATED 125 VOLT DC BUS RESULTED IN BOTH MOTOR DRIVEN     |
| AUXILIARY FEEDWATER PUMPS  STARTING.                                         |
|                                                                              |
|                                                                              |
| During routine scheduled maintenance activities, power was lost to a         |
| non-safety related 125 volt DC bus.  Loss of power to the bus resulted in    |
| loss of oil pressure indication on 1 of 2 channels on both main feedwater    |
| pumps, which in turn resulted in the actuation of both motor driven          |
| auxiliary feedwater pumps.  The motor driven auxiliary feedwater pumps ran   |
| for approximately 3 minutes. Reactor power increased but no over power event |
| occurred.                                                                    |
| Power has been restored to the non-safety related 125 volt bus and the motor |
| driven auxiliary feedwater pumps have been secured.                          |
|                                                                              |
| The licensee is looking into that maybe when cross connecting the 125 volt   |
| DC buses that one of the two fuse disconnect switches might have had a blown |
| fuse which would have resulted in the above event.                           |
|                                                                              |
| The NRC Resident Inspector was notified of this event by the licensee.       |
