Title | Failure to Include Security Diesel Generator into the Maintenance Rule Scoping Document |
Description | The inspectors identified a non-cited violation (NCV) of very low safety significance (Green) of 10 CFR Part 50.65 paragraph (b), Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, because Entergy did not include all aspects of the emergency lighting system into the Pilgrim Maintenance Rule scoping document. Specifically, Entergy did not include the security diesel generator in the scoping document, which provides backup power to emergency yard lighting, and is required to meet Appendix R emergency lighting requirements. Entergy has entered the issue into their corrective action program (CAP) to add the security diesel generator and normal power supplies for yard emergency lighting into the Maintenance Rule scoping document. The finding is more than minor because it is associated with the Procedure Quality attribute of the Mitigating Systems cornerstone, in that, the issue affected emergency lighting reliability in support of the accomplishment of EOPs. The finding was determined to be of very low safety significance (Green) because the finding did not involve a design or qualification deficiency resulting in loss of operability or functionality, did not result in a loss of system safety function, and did not screen as potentially risk significant due to external initiating events. The finding does not have a cross-cutting aspect since the failure to scope this equipment into the Maintenance Rule was not recognized during the initial Maintenance Rule scoping activities and as a result, is not indicative of current performance. |
