| Title | Failed to Establish Measures for the Selection and Review for the Suitability of Safety-Related Cables |
| Description | The inspectors identified a finding of very low safety significance and an associated NCV of Title 10, Code of Federal Regulations (CFR), Part 50, Appendix B, Criterion III, Design Control, where the licensee failed to establish measures for the selection and review for the suitability of safety-related cables with Procedure Electrical Cable Program Manual (ECPM) 4.5, Electrical Cable Operability, Revision 2. Specifically, ECPM 4.5, Attachment 1, Qualification of Cables in Wetted Environments, allowed for safety-related cabling that was not qualified or specifically designed for total submergence in water to be used in water filled conduits contrary to its unsuitability for this application, without suitable testing or design control measures. The licensee entered the issue into their Corrective Action Program as Action Request (AR) 01902782, ECPM Electrical Cable Operability, dated September 10, 2013, which suspended the use of ECPM 4.5 by quarantining the procedure until the identified discrepancies could be resolved. The performance deficiency was determined to be more than minor because the finding, if left uncorrected, would become a more significant safety concern. Specifically, not identifying and appropriately evaluating degraded or non-conforming conditions to properly assess the operability of cables subjected to protracted and/or extensive exposure to water could warrant not declaring a structure, system, and component (SSC) inoperable by the use of compensatory actions to maintain or enhance a degraded or non-conforming condition. This finding has a cross-cutting aspect in the area of human performance, decision-making because the licensee did not use conservative assumptions in implementing ECPM 4.5, Electrical Cable Operability, Revision 2. Specifically, the licensee failed to perform an effective review of the consequences of their decision to include an attachment to this procedure that provided a method not previously approved for qualifying safety-related cables for submergence. |
