| Title | Failure to Correct a Condition Adverse to Quality in a Timely Manner |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, for the licensees failure to correct a condition adverse to quality in a time commensurate with the safety significance of the issue. Specifically, the licensee failed to repair degraded conduit that had been identified as corroded since 2008. As a result, conduits that were housing cables for safety-related components were degraded to the point where water entered the conduit and submerged cables that were not designed for submergence for an extended period of time. The licensee entered this condition into their corrective action program as condition report CR-WF3-2014-04951. The licensee repaired the degraded conduit associated with the impacted safety-related cables to restore compliance, and also initiated an extent of condition review to identify other cables that could potentially be impacted by degraded conduits. The inspectors determined that the performance deficiency was more than minor because if left uncorrected the performance deficiency would have the potential to lead to a more significant safety concern. Specifically, safety-related cables that were not rated for full submergence were submerged in water since at least 2008, potentially affecting the integrity of the cable and potentially impacting the safety-related equipments ability to perform their safety function in the event of an accident. The inspectors determined that the finding had very low safety significance (Green) because the finding impacted the qualification of mitigating components, but the components maintained operability. This finding had a cross-cutting aspect in the area of Human Performance, Conservative Bias, because the licensees decision-making practices did not emphasize prudent choices over those that are simply allowable. Specifically, when evaluating condition reports written through several years that document the degraded conduit, the licensee elected to defer needed maintenance instead of placing the adequate priority on the issue. |
