| Title | Submerged Medium Voltage Cables |
| Description | The inspectors identified a Green finding (FlN) for the improper maintenance o
underground non-safety related medium voltage electric cables. The inspectors identifie that Entergy allowed non-safety related medium voltage cables to remain submerged i water for extended periods of time. Entergy entered this issue into their corrective actio program, specified corrective actions to increase the dewatering frequency of the affecte manhole, and then installed an automatic dewatering pump The inspectors determined that the finding was more than minor because it was associate with the Design Control attribute of the Initiating Events cornerstone and affected th cornerstone objective of limiting the likelihood of those events that upset plant stability an challenge critical safety functions during shutdown as well as power operations Specifically, continued submergence of the non-safety related power cables (from the startup transformer to electrical buses A2 and 44) could lead to cable failure and cause a event that would affect plant stability. The inspectors performed a Phase 1 Significanc Determination Process screening of the finding in accordance with NRC Inspection Manua Chapter 0609, Attachment 4, \\\"Phase 1 - Initial Screening and Characterization of Findings,\\\ and determined that the finding was of very low safety significance because the conditio did not contribute to both the likelihood of a reactor trip and the unavailability of mitigatin systems equipment The inspectors determined this finding had a cross-cutting aspect in the Proble ldentification and Resolution cross-cutting area, Corrective Action Program component because Entergy personnel did not implement corrective actions in a timely manner t ensure that underground cables were not submerged, commensurate with the safet significance and complexity of the degraded condition P.1(d).
