| 10 CFR PART 21 REPORT REGARDING A SUBSTANTIAL SAFETY HAZARD WITH A WOODWARD |
| GOVERNOR EGB UNIT |
| |
| 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.' |
| " |
| |
| The licensee notified the NRC resident inspector. |

| EARTHQUAKE FELT ONSITE |
| |
| 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. |
| |
| The NRC Resident Inspector was notified of this information call by the |
| licensee. |

| REACTOR WAS MANUALLY TRIPPED AT LESS THAN 1% POWER |
| |
| |
| 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. |
| |
| The NRC Resident Inspector was notified. |
