A finding of very low safety significance … A finding of very low safety significance and associated NCV of 10 CFR 50, Appendix B, Criterion III, Design Control, was identified by the NRC for the failure to maintain A Emergency Service Water (ESW) safety-related cables in an environment for which they were designed. The inspectors determined that the failure to maintain safety-related cables for the A ESW system in an environment for which they were designed was contrary to the requirements contained in 10 CFR 50, Appendix B, Criterion III, Design Control, and was therefore a performance deficiency. The licensee entered this event into their Corrective Action Program (CAP) as CAP 070938, and implemented corrective actions including creating inspection tasks to periodically inspect 21 manholes that are susceptible to water intrusion, as well as evaluating the feasibility of installing sump pumps in those manholes. The finding was determined to be more than minor because the finding was associated with the Mitigating Systems Cornerstone attribute of equipment performance and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee failed to maintain A ESW safety-related cables in an environment for which they were designed when the cables were allowed to be submerged in water inside manhole 1MH109. The finding was of very low safety significance (Green) because it was a qualification deficiency that did not result in a loss of operability. This finding has a cross-cutting aspect in the area of problem identification and resolution, corrective action program, because the licensee did not take appropriate corrective actions to address safety issues and adverse trends in a timely manner. Specifically, the licensee failed to implement timely corrective actions to address an adverse trend of water in manhole 1MH109 which led to A ESW safety-related cables being submerged in water. (P.1(d)d cables being submerged in water. (P.1(d)
