| Title | Failure to Adequately Implement Foreign Material Exclusion Controls |
| Description | The inspectors identified a cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, associated with the licensees failure to adequately implement Procedure EN-MA-118, Foreign Material Exclusion, Revision 5/6. Specifically, between October 31, 2008, and September 02, 2010, inspectors identified multiple occasions where licensee personnel failed to implement appropriate foreign material exclusion controls in Zone 1 areas around safety related equipment (e.g., failure to appropriately log material in to and out of the zone) as required by station procedure. Each identified instance was a repeat occurrence of previously identified issues that were documented as NRC identified violations in previous inspection reports in 2008, 2009, and early 2010. Measures established by Arkansas Nuclear One to address these previously identified noncited violations failed to restore compliance within a reasonable time after these violations were identified. Finally, these failures had the potential of having a negative impact on safety related components such as fuel failure, safety system reliability and safety related equipment availability. This issue was entered into the licensee\'s corrective action program as Condition Reports CR-ANO-1-2010-3155, CR-ANO-2-2010-1839, and CR-ANO-C-2010-2192. The performance deficiency was determined to be more than minor because it was associated with the human performance attribute of the Mitigating Systems Cornerstone, and affected the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences, and is therefore a finding. Using the Manual Chapter 0609, Significance Determination Process, Phase 1 Worksheets, the finding was determined to have very low safety significance because the finding: (1) was not a design or qualification issue confirmed not to result in a loss of operability or functionality; (2) did not represent an actual loss of safety function of the system or train; (3) did not result in the loss of one or more trains of nontechnical specification equipment; and (4) did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. The finding was determined to have a crosscutting aspect in the area of problem identification and resolution, associated with the corrective action program, P.1(d), in that the licensee takes appropriate corrective actions to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity. |
