| Title | Failure to Perform Plant Level Maintenance Rule Monitoring |
| Description | The inspectors identified a finding (FIN) associated with Entergy Nuclear Operations, Inc. (Entergy) procedure EN-DC-204, Maintenance Rule Scoping and Basis, because Entergy did not perform plant level monitoring in accordance with the criteria set forth therein. Specifically, the plant level performance criteria of Unplanned Scrams and Unplanned Power Changes were not monitored as Maintenance Rule performance criteria. Entergy entered this issue into its corrective action program (CAP) as condition report (CR)-PNP-2013-8114. The performance deficiency was more than minor because if left uncorrected it would have the potential to lead to a more significant safety concern, and because it is associated with the equipment performance attribute of the Initiating Events cornerstone and the associated cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, failure to monitor the plant against the required performance criteria and subsequent failure to evaluate for functional failures can result in the inability to identify systems that are not effectively being maintained and can contribute to events that upset plant stability and contribute to a significant event. In accordance with IMC 0609.04, Initial Characterization of Findings, and Exhibit 2 of IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, issued June 19, 2012, the inspectors determined that this finding is of very low safety significance (Green) because the finding was not a design or qualification deficiency, did not represent an actual loss of system safety function, did not represent an actual loss of safety function of a single train or two separate safety systems for greater than the technical specification allowed outage time, and did not represent an actual loss of safety function of one or more non-technical specification trains of equipment designated as risk significant in accordance with Entergys maintenance rule program. The finding has a cross-cutting aspect in the area of Human Performance, Resources component, because Entergy did not ensure that procedures are available and adequate to assure nuclear safety. Specifically, Entergy did not ensure that Maintenance Rule Bases Documents were updated to include all monitoring criteria requirements set forth in EN-DC-204. |
