| Title | Part 21 - Defect Identified in Emergency Diesel Generator Governor |
| Event Description | The following is a synopsis of information provided by the Engine Systems, Inc (ESI) via fax:
Component Description: Woodward Governor, Part No. 9903-722, Serial No. 18847017 Problem Description: An EGB-35P governor/actuator (governor) installed on a customer's emergency diesel generator failed soon after installation. Investigation revealed a piece of foreign material, a loose buffer plug, inside the governor that caused the failure. Since the governor is used to maintain fuel rack position of the diesel engine, failure of the governor would prevent the emergency diesel generator from performing its safety-related function during an event. Affected Plants: Brunswick Nuclear Plant Corrective Actions for Brunswick Nuclear Plant: No action required. The affected governor has been returned to ESI. Corrective Actions for ESI: The governor will be refurbished under ESI's 10 CFR 50 Appendix B program and certified for continued use at Brunswick Nuclear Plant. To prevent reoccurrence, ESI will revise the dedication requirements to enhance existing foreign material inspection practices to include a visual inspection where the buffer plug was located within the governor. The revisions are expected to be complete within 30 days but in all cases prior to future shipments. |
