| Title | Failure to Provide 8-HOUR Emergency Lighting in All Areas Where Operators Perform Manual Actions Required During an Alternative Shutdown |
| Description | Green. The team identified a non-cited violation of License Condition 2.E for the failure to provide 8-hour emergency lighting in all areas where operators perform manual actions required during an alternative shutdown. As a compensatory measure, the licensee added flashlights to the procedure box in the essential cooling water intake structure. The team noted that operators were also required to carry a flashlight while on shift. The licensee entered this issue into their corrective action program as Condition Report 17-1741. The failure to provide 8-hour emergency lighting in all areas where operators perform manual actions required during an alternativ e shutdown was a performance deficiency. The performance deficiency was more than minor because it was associated with the protection against external events (fire) a ttribute of the Mitigating Systems Cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to provide 8-hour emergency lighting could adversely affect the ability of operators to perform the manual actions required for an alternative shutdown. The team determined this finding affected the Mitigating Systems Cornerstone. The team evaluated this finding using Ins pection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, dated September 20, 2013, because it affected the ability to reach and maintain safe shutdown conditions in case of a fire. The team determined this finding was of very low safety significance (Green) in Task 1.3.1 because it had a low degradation rating. The finding did not have a cross-cutting aspect since it was not indicative of present performance in that the performance deficiency occurred more than three years ago. Specifically, the team determined that the per formance deficiency existed since original construction. |
