Title | Licensee-Identified Violation |
Description | 10 CFR 50 Appendix B, Criterion V, states in part that activities affecting quality shall be prescribed by documented instructions of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions. Contrary to this requirement, the licensee discovered that both redundant timing relays for the 2G 4160 VAC emergency switchgear were not calibrated per the licensees calibration procedure 57CP-CAL-204-0. During a surveillance test on March 31, 2009, it was discovered that both relays had failed to actuate which prevented the 2C EDG output breaker to close as expected. Because Unit 2 entered a RFO on February 9 and the last successful surveillance of these relays occurred on February 28 and the failure occurred during a RFO, the finding was evaluated in accordance with NRC inspection manual chapter 0609 Appendix G, Shutdown Operations SDP. Checklist 8 in attachment 1 of Appendix G was appropriate for plant conditions at the time of discovery. Using the checklist, the inspectors determined that the licensee maintained an adequate mitigation capability in four of the five shutdown safety functions and a Phase 2 and Phase 3 analysis was not required. Therefore, the finding screens as Green. The licensee entered this finding into their CAP as CRs 2008100277 and 2009103473 |
