| Title | Failure to Correct Non-conservative Safety Related Equipment Oil Leakage Criteria |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, for a failure to correct a condition adverse to quality. Specifically, the licensees calculations to determine acceptable oil leak rates of safety related pumps in response to Callaway Action Requests 201102434 and 201207677 failed to ensure that the pumps mission times could be met. As a result, non-conservative limits were added to Procedure ODP-ZZ-0016E, Appendix 1, Operations Technician General Inspection Guide. Specifically, the licensee revised the leakage limits to correctly account for the mission time, but failed to account for the time between observations during operator rounds. The licensee entered this issue into the corrective action program in Callaway Action Request 201308127. NRC inspectors determined there was never a time within the last several years when any of these pumps exceeded the revised oil leakage limits, once corrected. The inspectors determined that the failure to correct non-conservative oil leakage specifications used in operator logs is a performance deficiency. The inspectors determined that the performance deficiency was associated with the Mitigating Systems Cornerstone and was more than minor, and therefore a finding, because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, the failure to evaluate and determine appropriate lube oil leakage to maintain safety related equipment could have impacted the availability of mitigating systems if left uncorrected. The finding was assessed using Inspection Manual Chapter 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, and was determined to be of very low safety significance since the inadequate specifications did not result in a loss of operability for the affected systems. This finding has a cross-cutting aspect in the decision-making component of the human performance cross-cutting area because the licensee failed to utilize a systematic process to ensure safety is maintained, specifically the authority and roles for decisions affecting nuclear safety in the corrective actions for Callaway Action Requests 201102434 and 201207677 were not formally defined resulting in inadequate engineering conclusions being incorporated into operations procedures H.1(a). |
