| Title | Failure To Ensure Fire Door Was Engaged And Pinned |
| Description | The inspectors identified a finding of very-low safety significance (Green) and associated Non-Cited Violation of License Condition 2.C.15 for Unit 2, for the licensees failure to ensure all fire rated assemblies (i.e., fire doors) were operable. Specifically, during a plant walk down, the inspectors found Fire Door 282 inoperable. The lower pin of the stationary part of the double door was not engaged, because the pin was broken.The licensee entered the issue into their Corrective Action Program and as an immediate action, declared the door inoperable, established hourly fire watch, and subsequently installed a new pin.The inspectors determined that the performance deficiency was more-than-minor because the finding was associated with the Mitigating Systems cornerstone attribute of Protection Against External Factors (Fire) and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors determined that the issue screened as having very-low safety significance (Green) by answering Yes to Question 1.4.3.A of IMC 0609, Appendix F, Attachment 1 based on no combustible within 10 feet of Door 282 on the 5A4 side and one pin should still provide sufficient defense-in-depth for several hours before buckling or moving out of the frame. The finding had a cross-cutting aspect in the Procedure Adherence component of the Human Performance cross-cutting area. Specifically, the licensee failed to follow procedural guidance to thoroughly verify that fire doors were pinned when challenging the doors. [H.8] |
