| Title | Failure to Ensure Work Hours are Within Work Hour Limits |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 26, Fitness for Duty Programs, for the licensees failure to ensure that the calculated hours for individuals subject to work hour controls included all time performing duties for the licensee. Specifically, from November 1, 2015, to December 15, 2015, the licensees failure to accurately calculate work hours resulted in an individual exceeding work hour limits. The licensee entered this condition into their corrective action program as Condition Report CR-RBS-2015-09152. The licensee restored compliance when the affected individual received an adequate break time. Corrective actions included training operators on required work hours tracking as required by procedure EN-OM-123, Fatigue Management Program, Revision 12. The performance deficiency was more than minor, and therefore a finding, because it was associated with the human performance attribute of the Initiating Events Cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the failure to schedule and control work hours for individuals subject to work hour controls could reasonably result in human performance errors that could cause a plant event to occur or complicate the stations ability to respond appropriately to an event. The inspectors performed the initial significance determination using NRC Inspection Manual Chapter 0609, Appendix G, Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Initial Screening and Characterization of Findings. The inspectors determined that the finding was of very low safety significance (Green) because the finding did not cause any known effects to plant safety caused by worker fatigue. The finding had a cross-cutting aspect in the area of human performance associated with procedure adherence because the licensee failed to follow fatigue management program procedure EN-OM-123, Fatigue Management Program, Revision 12, which required the licensee to track all work hours subject to the work hour limits. |
