Title | Inadequate Extent of Cause Results in Missed Safety-Related Pump Overhaul |
Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, associated with the licensee\'s failure to promptly identify and correct a condition adverse to quality. Specifically, the licensee reduced the scope of preventative maintenance for the turbine-driven auxiliary feedwater pump overhaul during Refueling Outage 16 without proper justification, resulting in the failure to perform required pump maintenance. This issue was entered into the licensee\'s corrective action program as Callaway Action Request 201102407 and the pump has been scheduled to be overhauled during the next refueling outage. This finding is more than minor because, if left uncorrected, corrective action deficiencies would have the potential to lead to a more significant safety concern. The failure to perform required maintenance could allow equipment degradation affecting the equipment performance attribute of the Mitigating Systems Cornerstone and could have impacted the availability of mitigating equipment if left uncorrected. Using Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, this finding was determined to be of very low safety significance because the degraded condition did not result in a loss of operability or functionality. The inspectors determined that the finding has a cross-cutting aspect in the area of human performance associated with the work control component because the licensee does not appropriately coordinate work activities by incorporating actions to address the impact of changes to work scope on the plant such that nuclear safety is supported. |
