| Title | |
| Description | The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, because PNPS staff failed to identify and correct conditions adverse to quality associated with the partial voiding of the A core spray (CS) discharge header on January 27, 2015, following the loss of the keepfill system due to a LOOP. PNPS entered the issue into the CAP as CR-PNP-2015-01406 and planned procedural changes that would provide guidance to operate the affected pumps in order to prevent pump discharge piping from voiding if keepfill pressure is lost. The failure to identify, evaluate, and correct the A CS discharge header partial voiding following loss of keepfill on January 27, 2015, is a performance deficiency that was within Entergys ability to foresee and correct. Because the issue was not entered into the CAP, the condition was neither evaluated nor was corrective action taken or planned. This NRCidentified issue is more than minor because it is associated with the Mitigating Systems cornerstone attribute of equipment performance and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, to IMC 0609, Significance Determination Process. This finding was determined to be of very low The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, because PNPS staff failed to identify and correct conditions adverse to quality associated with the partial voiding of the A core spray (CS) discharge header on January 27, 2015, following the loss of the keepfill system due to a LOOP.
