| Title | Inspection Fails to Identify Safety Related Cables Submerged in Cable Vault |
| Description | The inspectors identified a finding of very low safety significance (Green) and associated NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action Program, for the failure to identify a condition adverse to quality. Specifically, the licensee failed to identify that portions of the Division 1 SX safety related cables, which are not rated for submergence, were under water. The licensee entered this issue into their corrective action program as action requests AR 02648804 and AR 02648507. Operators took actions to pump out the water to ensure the cables were returned to a dry condition. The inspectors determined the licensees failure to identify a condition adverse to quality was contrary to 10 CFR 50, Appendix B, Criterion XVI, Corrective Action Program, and was a performance deficiency. The performance deficiency was determined to be more than minor because the finding was associated with the Mitigating Systems Cornerstone objective of ensuring the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, because the SX cables are not rated for submergence, they could degrade and affect the reliability of the SX system. The finding was screened against the Mitigating Systems cornerstone and determined to be of very low safety significance (Green) because the inspectors answer Yes to the question does the SSC maintain its operability or functionality. Specifically, the SX system submerged cables did not cause the SX system to be inoperable or nonfunctional. The inspectors determined that this finding had a cross-cutting aspect in the area of human performance in the aspect of resources, where leaders ensure that personnel, equipment and other resources are available and adequate to support nuclear safety. Specifically, the individuals performing the inspection did not have the necessary resources, such as training, procedures, drawings or a detailed pre-job brief, to identify the cables sloped downwards in the cable vault and were submerged in the water.
