The inspectors identified a Green NCV of T … The inspectors identified a Green NCV of Title10 of the Code of Federal Regulations (10 CFR) 50.65, Requirements for monitoring the effectiveness of maintenance at nuclear power plants, for failure to adequately manage the increase in risk during planned maintenance on the A emergency diesel generator (EDG). Specifically, Entergy staff action to make the C EDG unavailable while the A EDG was already unavailable resulted in an unplanned increase in overall plant risk and deviation from the approved EDG outage risk management plan from a risk category of Green to the next higher risk category of Yellow. As immediate corrective action, the issue was entered into the corrective action program (CAP) as condition report (CR)-JAF-2015-05242. The finding was more than minor because it was associated with 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. Specifically, the C EDG was not available when it should have been, in accordance with the approved risk management plan, which resulted in an unplanned escalation of risk from Green to Yellow. Additionally, this finding was similar to example 7.e in IMC 0612, Appendix E, Examples of Minor Issues. In accordance with IMC 0609.04, Initial Characterization of Findings, and Exhibit 2 of IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At- Power, the inspectors determined that this finding was of very low safety significance (Green) because the performance deficiency was not a design or qualification deficiency, did not involve an actual loss of safety function, did not represent actual loss of a safety function of a single train for greater than its Technical Specification (TS) allowed outage time, and did not screen as potentially risk-significant due to a seismic, flooding, or severe weather initiating event. The finding had a cross-cutting aspect in the area of Human Performance, Work Management, because FitzPatrick did not execute the A EDG maintenance outage work activities as planned, and after deviating from that plan, did not identify and manage the risk of barring the C EDG while the A EDG was unavailable (H.5).EDG while the A EDG was unavailable (H.5).
