| Title | Part 21 Report - Speed Switch Capacitor Failure |
| Event Description | The following is a summary of a submitted facsimile:
Engine Systems Inc. (ESI) began a 10 CFR 21 evaluation on August 26, 2015 upon notification by Harris Nuclear Plant of a ground fault condition after installing two speed switches, P/N ESI50267B, supplied by ESI. Subsequent investigation revealed the condition was due to a failed capacitor installed across the relay output to ground within each speed switch. The evaluation was concluded on October 22, 2015 and it was determined that this issue is a reportable defect as defined by 10 CFR Part 21 . The speed switch output contacts are utilized in the engine's start circuitry and failure of the contacts to function properly could adversely affect the safety-related operation of the emergency diesel generator set. This issue only affects one part number (qty 6) supplied on one customer purchase order: ESI Sales Order: 3013958 Part Number: ESI50267B Customer: Duke Energy Progress - Harris Nuclear Plant Customer P.O.: 00763117 ESI Serial Numbers: 3013598-1.1-1, 3013598-1.1-2, 3013598-1.1-3, 3013598-1.1-4, 3013598-1.1-5, 3013598-1.1-6 C of C Date: April 10, 2015 Point of Contact: Tom Horner, Quality Assurance Manager, Engine Systems, Inc., phone (252) 977-2720 |
