| Title | Failure to Follow Procedure for Operation of the Containment Emergency Air Lock Doors |
| Description | The inspectors reviewed a self-revealing non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to follow procedure for performing surveillance testing of the containment emergency air locks. Specifically, licensee personnel failed to fully close the Unit 1 containment emergency airlock exterior door and equalizing valve after performance of a door seal leak surveillance test. As a result, the containment emergency air lock exterior door was inoperable. Upon discovery, the licensee properly closed the containment emergency airlock door. The licensee entered the finding into the corrective action program as Condition Report CR-2013-000264. The finding was more than minor because it was associated with the human performance attribute of the Barrier Integrity cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that containment physical design barriers protect the public from radionuclide releases caused by accidents or events. Using Inspection Manual Chapter 0609, Attachment 04, Initial Characterization of Findings, and Appendix A, Exhibit 3, Barrier Integrity Screening Questions, the finding was determined to be of very low safety significance (Green) because the finding did not represent an actual open pathway in the physical integrity of reactor containment. The finding has a human performance cross-cutting aspect associated with resources, in that, the licensee failed to ensure that equipment and procedures were adequate to support nuclear safety [H.1]. |
