| Title | Failure to Manage a Yellow Risk Condition for Unavailable Torus Vent Valve |
| Description | The inspectors identified a Green NCV of Title 10 of the Code of Federal Regulations (10 CFR) 50.65 paragraph (a)(4) because Entergy did not identify and manage risk for emergent maintenance on primary containment isolation valves (PCIVs). Specifically, an incorrect risk assessment resulted in Entergy not recognizing an increase in risk to a Yellow condition, and therefore no risk management actions were taken. Entergy has captured this issue in condition report (CR)-PNP-2014-2007, has corrected the inadequate risk assessment, and has initiated an apparent cause evaluation (ACE) to determine causes and appropriate corrective actions. The performance deficiency was more than minor because if left uncorrected the failure to recognize risk and take appropriate risk management actions has the potential to lead to more significant safety concerns. Moreover, a review of IMC 0612, Appendix E, Minor Examples, identified that Section 7, Maintenance Rule, Example e, reflected a similar more than minor example, in that the outcome of the overall elevated plant risk put the plant into a higher risk management category and thereby required additional risk management actions. In accordance with IMC 0609.04, Initial Characterization of Findings, and IMC 0609, Appendix K, Maintenance Risk Assessment and Risk Management Significance Determination Process, issued May 19, 2005, the inspectors determined that this finding is of very low safety significance (Green) because the Incremental Core Damage Probability Deficit for the duration of the activity was less than 1.0 E-6 per year (approximately 1.29 E-7 per year). This finding has a cross-cutting aspect in the area of Human Performance, Consistent Process, because when faced with the requirement to perform emergent, unscheduled maintenance, Entergy did not use a consistent, systematic approach to make decisions, and did not incorporate appropriate risk insights. Specifically, while Entergy had the tools and processes in place to assess risk for emergent conditions, individuals did not consistently use this process, and therefore did not recognize the elevated risk condition. |
