| Title | Failure to Ensure The Operability of an Emergency Battery Lighting Unit in Accordance with the Approved Fire Protection Plan |
| Description | The inspectors identified an NCV of the Unit 1 Operating License Condition 2.F for the licensees failure to maintain the operability of Appendix R emergency lighting in accordance with the approved Fire Protection Plan (FPP). Specifically, both lamps for an Appendix R emergency light in the Unit 2B 480 volt transformer room were not aimed in the direction required by design to accomplish the operator manual action to restore outside air ventilation to the room in the event of a fire, as required by the FPP. The licensee implemented compensatory measures and entered this issue into the corrective action program as Problem Evaluation Report (PER) 341645. The finding was determined to be more than minor because it affected the protection against external events attribute of the Mitigating Systems cornerstone, in that it affects the objective of ensuring reliability and capability of systems that respond to initiating events. This finding was evaluated using Inspection Manual Chapter (IMC) 0609, Appendix F, Attachment 1, and was determined to be of very low safety significance because it was not a major degradation of FSSD capability. The cause of the finding was directly related to the cross-cutting aspect of Effective Supervisory/Management Oversight in the Work Practices component of the area of Human Performance, in that the licensee did not ensure oversight of work activities that adversely affected the operability of Appendix R emergency lighting |
