| Title | Failure to Assess and Manage Risk for Maintenance That Could Impact Initiating Events |
| Description | The inspectors identified a cited violation of 10 CFR 50.65(a)(4), Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, for the failure of work control and operations personnel to adequately assess and manage the increase in risk associated with maintenance activities. Specifically, on February 17, 2011, work control and operations personnel failed to adequately assess and manage the increase in risk associated with maintenance activities involving the use of heavy equipment in or near the electrical switchyard and offsite power components. Due to the licensees failure to restore compliance from the previous NCV 050000298/2008005-02 and other subsequent violations within a reasonable time after the violations were identified, this violation is being cited in a Notice of Violation consistent with Section 2.3.2 of the NRC Enforcement Policy. This finding was entered into the licensees corrective action program as condition reports CR-CNS-2010-09146, CR-CNS-2008-08645 and CR-CNS-2009-03714. The performance deficiency associated with this finding involved the licensees failure to adequately assess and manage the risk of planned maintenance activities. This finding is greater than minor because it affected the protection against external factors attribute of the Initiating Events Cornerstone, and directly affected the 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. The inspectors determined that Manual Chapter 0609, Appendix K, Maintenance Risk Assessment and Risk Management Significance Determination Process, could not be used due to the licensees inability to quantify the increase in risk associated with the heavy equipment activity in the switchyard. The inspectors therefore used Manual Chapter 0609, Appendix M, Significance Determination Process Using Qualitative Criteria. The inspectors performed a bounding qualitative evaluation using the best available information and determined that the finding was of very low safety significance because another qualified source of offsite power (the emergency transformer) was unaffected by this performance deficiency and provided sufficient remaining defense in depth in the event of a loss of offsite power. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee did not take appropriate corrective actions to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity P.1(d)(Section 1R13). |
