| Title | Failure to Initiate a Condition Report for Degraded Undervoltage Relay |
| Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, for the failure to follow procedures that require initiating a condition report for degradation to safety-related equipment. During a surveillance activity, maintenance personnel discovered that an undervoltage relay was outside the as-found setpoint for pick-up voltage and failed to enter the condition into the corrective action program. As a result, the cause and effect of the degraded condition was not evaluated. The licensee entered the finding into the corrective action program as condition report CR-2010-001429. The finding was more than minor because if the licensee continues to fail to document degraded safety-related equipment in the corrective action database, there is potential that this could lead to a more significant safety concern, in that, the cause of the degradation will not be evaluated and corrected. Using NRC Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance because the finding did not result in the inoperability of safety-related relays. This finding has a problem identification and resolution crosscutting aspect associated with the corrective action program, in that, the licensee did not implement a corrective action program with a low threshold for identifying issues P.1a] |
