| Title | Failure to Identify, Document, and Mitigate Risk from LongTerm Deficient Conditions |
| Description | The team identified a Green, non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to identify, document, and mitigate risk from long-term deficient conditions, as required by the Procedure EN-LI-102, Corrective Action Program, Revision 24. The failure to identify, document, and mitigate risk from long-term deficient conditions, as required by Procedure EN-LI-102, was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, the delayed corrective actions and unmitigated deficiencies could reduce the reliability of the Unit 2 emergency diesel generator A, alternate ac diesel generator, and Unit 2 non-vital switchgear. This finding is associated with the Mitigating Systems cornerstone. Using Inspection Manual Chapter 0609, Appendix A, the team determined that the finding was of very low safety significance (Green) because it did not result in the loss of operability or functionality of any system or train and did not screen as risk-significant in response to external events. This finding has a human performance cross-cutting aspect associated with conservative bias in that the licensee failed to use decision-making-practices that emphasize prudent choices over those that are simply allowable and failed to determine that a proposed action was safe in order to proceed, rather than unsafe in order to stop (H.14). |
