| Title | Risk Management Actions Not Implemented to Manage Increased Online Risk During a Surveillance Test |
| Description | The inspectors identified a Green NCV of 10 CFR 50.65(a)(4), Requirements for monitoring the effectiveness of maintenance at nuclear power plants, when Exelon did not implement risk management actions to manage the risk associated with the performance of surveillance activities on containment spray system 1. The inspectors determined that not implementing risk management actions to mitigate an increased overall maintenance risk was a performance deficiency that was within Exelons ability to foresee and correct. Exelons immediate corrective actions included resetting the crew clock and briefing the remaining operating crews on the details of this event. Exelon entered this issue into the corrective action program for resolution as IR 1324575. The inspectors determined that this issue is more than minor because it is similar to example 7.g in Inspection Manual Chapter (IMC) 0612, Appendix E, Examples of Minor Issues in that key safety functions were significantly degraded without sufficient compensation. The inspectors determined that this finding affected both the Mitigating Systems and Barriers Integrity cornerstones. The inspectors used Inspection Manual Chapter 0609, Appendix K, Maintenance Risk Assessment and Risk Management Significance Determination Process, flowchart 2, Assessment of Risk Management Actions, to analyze the finding. As this finding is a 10 CFR 50.65(a)(4) performance issue associated with risk management actions only and the ICDP is not >1E-6, the inspectors determined that the finding is of very low safety significance (Green). This finding has a crosscutting aspect in the area of Human Performance, Work Practices, because Exelons supervisory oversight of work activities did not support nuclear safety. |
