| Title | Failure to Periodically Test Emergency Lighting Units |
| Description | The team identified a non-cited violation of License Condition 2.C.9, Fire Protection, for the failure to periodically test and demonstrate the 8-hour capacity of the Appendix R emergency lighting units. The licensee entered this issue into their corrective action program as Condition Report CR-WF3-2015-00856 and operators had flashlights available as a compensatory measure. The failure to periodically test and demonstrate the 8-hour capacity of the Appendix R emergency lighting units was a performance deficiency. The performance deficiency was more than minor because it was associated with the protection against external events (fire) attribute 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. The team evaluated this finding using Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, dated September 20, 2013. The team assigned the finding a low degradation rating because it would not prevent reaching and maintaining safe shutdown conditions in the event of a control room fire. Specifically, the team had reasonable assurance that the emergency lighting units would provide adequate illumination for a sufficient amount of time for operators to perform the most time critical actions. In addition, the team determined that operators performing an alternative shutdown had flashlights available in the Appendix R equipment lockers. Because the team assigned a low degradation rating, this finding screened as having very low safety significance. This 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. |
