The NRC identified a Green Non-Cited Violation (
NCV) of Unit 1 License Condition 2.C.(3) Fire Protection when a fire penetration that deviated from three-hour rating requirements was not evaluated in accordance with Unit 1 Fire Hazards Analysis (
FHA) Appendix I, Evaluation of non-rated penetration seals in rated
fire barriers. The licensee initiated roving fire watches and initiated corrective actions to restore compliance with Appendix I of the Unit 1
FHA. The violation was entered into the licensees corrective action program as CR 865615. Failure to implement the Unit 1 Fire Hazards Analysis (
FHA) Appendix I, Evaluation of nonrated penetration seals in rated
fire barriers was a performance deficiency. This performance deficiency was more than minor because it was associated with the
Mitigating Systems cornerstone of the Protection Against External Factors (Fire) attribute and adversely affected the cornerstone objective in that the licensee failed to evaluate the asfound configuration of the penetration which resulted in a nonfunctional
fire barrier. The inspectors determined the finding was Green because there was a fully functional automatic suppression system on either side of the
fire barrier. The inspectors determined that thi
finding did not have an associated cross-cutting aspect because this finding is not reflectiv
of current licensee performance.
