| Title | Failure to Adequately Control Non-Conforming or Degraded Equipment |
| Description | The inspectors identified an NCV of 10 CFR 50, Appendix B, Criterion XV, Nonconforming Materials, Parts, or Components, for the licensees failure to ensure that 6.9Kv breaker 0-BKR-569-4605025-S, which had been identified as defective, was not labeled or otherwise segregated to prevent it from being installed into the plant. The licensees failure to ensure that defective 6.9Kv breaker 0-BKR-569-4605025-S was not installed into the plant is a performance deficiency. The inspectors reviewed IMC 0612 and determined that the finding was more than minor because, if left uncorrected, it would have the potential to lead to a more significant safety concern; specifically, the subject safety-related breaker could have been installed in a more critical application or have been installed for a longer period of time, up to 18 months, in the Alternate Feeder application. Additionally, the finding was associated with the configuration control attribute of the Initiating Events cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Using the Phase I screening worksheet of IMC 0609, the inspectors determined that the finding was of very low safety significance (Green) because it would not contribute to both a reactor trip and the likelihood that mitigation equipment or functions would not be available. The cause of the finding was directly related to the cross-cutting aspect that the licensee ensure supervisory and management oversight of work activities in the Work Practices component of the cross-cutting area of Human Performance, in that the licensee failed to ensure that a defective component was not installed into the plant.
