| Title | Installation of 1.5-hour UL Labeled Fire Door in a Required 3-hour Fire Barrier on Unit 2 |
| Description | An NRC-identified non-cited violation (NCV) of Unit 2 Operating License Condition (OLC) 2.C. (6), Fire Protection, was identified for the failure to ensure that a fire door that was part of a fire barrier was provided with a 3-hour labeled door as required by 10 CFR 50.48 and the approved Fire Protection Program (FPP). Fire Area 2-20, Auxiliary Building Corridor is required to be separated from Fire Area 2-21, Unit 2 Train B Switchgear Room, by 3-hour rated fire barriers. The inspectors observed that fire door 2219, in the wall separating these two fire areas, was installed with a Underwriters Laboratory (UL) label fastened to it, identifying it as a 1.5-hour rating rather than a labeled 3-hour rated fire door. The licensee entered these issues into the corrective action program (CAP) as CRs 814872, 843303 and 840832, and implemented an hourly roving fire watch in the affected Fire Areas as a compensatory measure, LCO No. 2-2014-0111. The licensees failure to ensure that fire door 2219 was a functional UL labeled Class A 3-hour door, as required by the approved FPP, was determined to be a performance deficiency. The performance deficiency was more than minor because it was associated with the protection against external events (fire) attribute of the Mitigating Systems Cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The significance of this finding was evaluated using IMC 0609, Appendix F, Fire Protection Significance Determination Process , dated September 20, 2013 because the performance deficiency affected fire protection defense-in-depth strategies involving fire confinement. Using IMC 0609, Appendix F, Attachment 1, Fire Protection Significance Determination Process Worksheet, the inspectors determined that the finding was of very low safety significance (Green) at Task 1.4.3, Question B, because the barrier door (as evidenced by a UL door label of 1.5-hours) will provide a 1-hour or greater fire endurance rating. A Cross Cutting Aspect of H.12, Avoiding Complacency was assigned to this finding because individuals did not recognize or plan for the possibility of mistakes, issues or risk during the fire doors receipt inspection, installation and post-installation surveillance. |
