|                                                                              |
| The following text is a portion of a facsimile received from the licensee:   |
|                                                                              |
| "On 1/12/01, V. C. Summer Nuclear Station (VCSNS) determined that a          |
| Substantial Safety Hazard could exist with Woodward governor EGB units       |
| failing to properly control the Emergency Diesel Generator [(EDG)].  A       |
| condition report (received on 1/12/01) from B. F. Goodrich/Fairbanks Morse   |
| indicated there was binding of the terminal shaft internal to an EGB unit    |
| removed from the 'A' EDG at VCSNS.  The disassembly inspection found that    |
| the binding of the terminal shaft was due to the use of clamping screws,     |
| which were 1/8 inch longer than specification, resulting in binding on the   |
| output servo piston connecting rod.                                          |
|                                                                              |
| "This error was made during the prior refurbishment of the EGB by Engine     |
| Systems Inc. (ESI), the Woodward Governor nuclear representative, on         |
| 2/24/00.  The use of the longer screws resulting in binding in the unit is   |
| considered a defect, which was introduced during the repair process by ESI.  |
|                                                                              |
| "[VCSNS] utilizes these EGB units on both the 'A' and 'B' EDGs.  The above   |
| condition produced severe frequency oscillations on the output of the 'A'    |
| EDG.  This condition could have been introduced to any EGB during            |
| refurbishment by ESI, passed acceptance testing, and be present on both      |
| EDGs.  In an emergency condition, both EDGs could fail, resulting in the     |
| loss of safety function for the emergency on-site power supply.              |
|                                                                              |
| "The EGB units currently installed on both EDGs have been refurbished by     |
| Fairbanks Morse with properly specified parts.  Fairbanks Morse will perform |
| all future EGB refurbishment work for VCSNS.  Other cause and corrective     |
| actions associated with the governor issues are being addressed under Root   |
| Cause Analysis report RCA 01-0235, 'Diesel Generator 'A' Governor Problems.' |
| "                                                                            |
|                                                                              |

| At 1057PST an earthquake in Western Washington State with a magnitude of 7.0 |
| was felt onsite.  The epicenter  is located 11.3 miles NE of Olympia, WA and |
| 14.9 miles West South West of Tacoma, WA.  The depth of the earthquake was   |
| 30 miles.   Seismic sensors did not detect the seismic activity. Plant       |
| inspection performed after the earthquake found no abnormal conditions.      |

| A manual reactor trip was initiated at 0017 on 3/01/01 due to 2 shutdown     |
| control rods remaining on the bottom while initiating control rod            |
| withdrawal.  This occurred during low power physics testing and a trouble    |
| shooting plan for a misaligned Shutdown bank B Control rod (G-9).  The rod   |
| had already been realigned to the other rods in shutdown bank B @ 43 steps.  |
| The Shutdown bank was inserted into the core to zero steps per the trouble   |
| shooting plan.   After the step counters and rod control were reset and      |
| Shutdown bank B rods were being withdrawn, it was discovered that 2 rods had |
| not moved and were still on the bottom with 14 steps demanded. The Shutdown  |
| bank was re-inserted to zero steps (fully inserted).   After further         |
| discussion, the shift supervisor called for a manual reactor trip.  The      |
| reactor operator tripped the Reactor and the Crew entered the Emergency      |
| Operation Procedures  (EOP-1.0, Reactor trip/safety injection, and EOP-1.1,  |
| Reactor trip recovery).   All systems functioned as designed.  The problem   |
| with the rod control system is not understood and trouble shooting is        |
| continuing.                                                                  |

| Note: The 2 rods that did not move were rods G-9 and L-5, both in Shutdown   |
| bank B.                                                                      |
