| LOSS OF RESERVE STATION TRANSFORMER CAUSED LOSS OF REACTOR COOLANT PUMP      |
| WHICH REQUIRED A REACTOR TRIP                                                |
|                                                                              |
| The 'C' reserve station transformer (RST) deenergized which resulted in a    |
| loss of the Unit 2 'C' reactor coolant pump (RCP).   The Unit 2 loss of RCP  |
| 'C' required a reactor trip, which was initiated manually, all rods fully    |
| inserted and the plant is stable in Hot Standby.  Unit 2 was on the steam    |
| dumps to the condenser and main feedwater at the time of the trip and        |
| continue on them.                                                            |
|                                                                              |
| Unit 1 '1H' emergency bus was lost due to the problem with the 'C' RST and   |
| the failure of the '1H' emergency diesel generator (EDG) to start.  The loss |
| of the '1H' bus caused the loss of the 'C' RCP and 'A' Residual Heat Removal |
| (RHR) pump, which led to the loss of core cooling circulation, but was       |
| restored in less than 2 minutes by starting the 'B' RHR pump.                |
|                                                                              |
| The 'C' RST and the '1H' EDG problems are being investigated, the cause of   |
| the problems are unknown at this time.  Unit 2 will remain in Hot Standby    |
| until all problems are corrected.                                            |
|                                                                              |

| The licensee made a correction to the reporting criteria.  Removed the       |
| original criteria of 10 CFR 50.72(b)(1)(ii) Degraded  Condition During       |
| Operation, this was for Unit 1 which was shutdown at the time.  Added the    |
| criteria 10 CFR 50.72(b)(2)(ii) ESF Actuation, due to a real start signal to |
| two of the emergency diesel generators.                                      |

| TWO CONTAINMENT ISOLATION VALVES CLOSED DUE TO BLOWN FUSES                   |
|                                                                              |
| The Nuclear Safety and Compliance Group notified Operations today that a     |
| report of ESF activation should be made to the NRC.  The group noted that    |
| during the review of a logic system functional testing on diesel generator   |
| 2R43-S001A, a logic power fuse (2A71-F21A) blew closing two primary          |
| containment isolation valves (2G11-F003 & 2G11-F019).  These valves are the  |
| inboard drywell sump isolation valves.  This occurred on 4/2/00 at 0030      |
| EDT.                                                                         |
|                                                                              |
| The system was checked, fuses replaced, and the valves opened.  The valves   |
| are fully operational.                                                       |
|                                                                              |
| The licensee notified the NRC Resident Inspector.                            |
