| Title | Failure to Initiate a Condition Report for a Degraded Reactor Coolant Pump Motor Lower Oil Reservoir |
| Description | The inspectors reviewed a self-revealing non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, for the failure to follow procedures that require initiating a condition report for degradation of equipment. During a maintenance activity, the licensee discovered that the reactor coolant pump motor lower oil reservoir level was low and failed to enter the condition into the corrective action program. As a result, the cause of the degraded condition was not evaluated. The licensee entered the finding in the corrective action program as Condition Report CR-2012-011607. The licensees failure to initiate a condition report for a degraded reactor coolant pump motor lower oil reservoir was a performance deficiency. The finding was more than minor because it was associated with the equipment performance attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective. It increased the likelihood of those events that upset plant stability and challenge critical safety functions during power operations. Using NRC Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings At-Power, the finding was determined to be of very low safety significance because the finding did not contribute to both the cause of a reactor trip and affect mitigation equipment. The finding had a problem identification and resolution cross-cutting aspect associated with the corrective action program, in that, the licensee did not ensure issues potentially impacting nuclear safety are fully evaluated. Specifically, the licensee did not trend and assess the issues associated with the leaking reactor coolant pump motor oil reservoir. |
