| Title | Emergency Lighting Not Installed as Required by 10 CFR 50 Appendix R Section III.J |
| Description | An NRC identified non-cited violation of 10 CFR 50, Appendix R, Section III.J, and the North Anna Power Station (NAPS) approved Fire Protection Program, was identified for the licensees failure to install fixed emergency lighting units (ELUs) in all areas where local operator manual actions (OMAs) were being performed to support post-fire safe shutdown (SSD). Specifically, a fixed ELU was not installed in the Unit 1 auxiliary building in the vicinity where an OMA to close valve 1-CC-757 was specified by fire contingency action (FCA) procedures for a fire in the main control room (MCR) or the Unit 1 emergency switchgear room (ESWGR). The licensee entered this issue in the corrective action program as condition reports 499353 and 500023. The licensees failure to comply with the requirements of 10 CFR 50, Appendix R, Section III.J, and the NAPS approved FPP, was a performance deficiency. The finding was more than minor because it was associated with the reactor safety Mitigating Systems cornerstone attribute of protection against external factors (i.e., fire), and it negatively affected the objective of ensuring the reliability and capability of systems that respond to initiating events. Specifically, the finding had the potential to affect the feasibility of performing the OMA required for SSD in the event of a fire in either the MCR or ESGR-1. Using IMC 0609, Appendix F, Fire Protection SDP Phase 1 Qualitative Screening Approach, Step 1.3, the inspectors concluded that the finding, given its low degradation rating, was of very low safety significance (Green) because the FCA procedures required the operators performing the SSD actions to carry a portable lantern, and the operators had a high likelihood of completing the tasks using the portable lanterns. The inspectors determined that no cross cutting aspect was applicable to this performance deficiency because this finding was not indicative of current licensee performance. |
