The inspectors identified a Green non-cited violation (
NCV) of
10 CFR Part 50.65, Maintenance Rule, for the licensee\'s failure to identify and correct deficiencies in the 8-hour emergency light preventive maintenance program. The licensee entered the issues into their corrective action program as
PIPs-C-13-03973, C-13-00996, C-13-03536 and C-13-03537. The deficiency will be mitigated by the operators use of flashlights until the deficiencies are corrected. The licensee\'s failure to identify and correct deficiencies in the emergency light preventive maintenance program was a performance deficiency. The performance deficiency was more than minor because it adversely affected the
Mitigating Systems cornerstone of protection against external events. Specifically, the high failure rate of emergency light testing resulted in a lack of reasonable assurance that adequate lighting would be available during fire events. The inspectors determined the finding to be of very low safety significance (Green) because the inspectors noted that operators were required to obtain and carry flashlights. The inspectors identified a cross-cutting aspect in the corrective action program component of the problem identification and resolution area.
