The inspectors identified a finding of ver … The inspectors identified a finding of very low safety significance and associated NCV of the Perry Nuclear Power Plant, Unit 1, Facility Operating License Condition 2.C.(6) and 10 CFR Part 50, Appendix R, Section III.G.2, involving the licensees failure to ensure, in the event of a fire, that one redundant train of systems necessary to achieve and maintain hot shutdown conditions was free of fire damage. Specifically, the licensee failed to ensure, in the event of a control room fire that certain Systems, Structures, and Components (SSCs) necessary to achieve and maintain hot shutdown conditions (e.g., MOVs 1P45-F0014A and 1P45-F0068A and emergency service water system (ESW) equipment) were free of fire damage. The licensee entered this finding into their corrective action program for resolution as CR 09-60977. The control room area, which is susceptible to this condition, is continuously manned; therefore making a compensatory action of a fire watch un-necessary. The finding was determined to be more than minor because the finding was associated with the mitigating systems cornerstone attribute of protection against external factors (Fire) and affected the cornerstones objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The Phase 2 screening determined this finding was of very low safety significance because no potentially challenging fire scenarios were developed challenging fire scenarios were developed +
