| Title | Failure to Identify Water Intrusion into Cable Conduits Containing Safety-Related Cables |
| Description | A finding of very low safety significance and associated NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, was identified by the inspectors for the licensees failure to promptly identify and correct a condition adverse to quality. Specifically, the licensee failed to identify that conduits containing safety-related cables were subject to water intrusion following the discovery of water filling an adjacent conduit containing non-safety related cables in the same cable vault. The licensee entered the issue into the corrective action program (CAP) as condition report (CR) 577166, implemented shiftly inspections of the cable vault, and performed inspections and dewatering of the safety-related cable conduits. The inspectors determined that the issue was a performance deficiency because it was the result of the failure to meet a requirement, and the cause was reasonably within the licensees ability to foresee and correct and should have been prevented. The inspectors determined that the performance deficiency was more than minor and a finding because, if left uncorrected, it had the potential to lead to a more significant safety concern. The finding was of very low safety significance because the finding was a qualification deficiency that did not result in a loss of operability. The inspectors determined that the contributing cause that provided the most insight into the performance deficiency affected the cross-cutting area of Problem Identification and Resolution, having corrective action program components, and involving aspects associated with thoroughly evaluating problems such that the resolutions address causes and extent of conditions, as necessary. |
