| description = The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, involving the licensees failure to correct an adverse condition on a safety related system. Specifically, when a low oil condition was identified on an emergency diesel generator governor, the licensee fixed the symptom by adding oil, but failed to correct the condition by stopping the leak. This issue was entered into the licensees corrective action program as Callaway Action Request 201206798. Failure to correct an adverse condition on a safety related system was a performance deficiency. This finding was more than minor because it adversely affected the equipment performance attribute of the Mitigating Systems Cornerstone, and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Manual Chapter 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the finding was determined to be of very low safety concern because it affected the qualification of a mitigating system, but the affected train was still able to meet its PRA mission time. This finding has a cross-cutting aspect in the area of Problem Identification and Resolution associated with the Corrective Action Program component because the licensee failed to thoroughly evaluate the problem such that the resolutions address causes including properly classifying, prioritizing, and evaluating for operability and reportability conditions adverse to quality. | | description = The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, involving the licensees failure to correct an adverse condition on a safety related system.
