The inspectors identified a non-cited violThe inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, because the licensee failed to determine the cause of a significant condition adverse to quality and take - 4 - Enclosure 2 corrective actions to preclude repetition. Specifically, the licensee failed to assure that the cause of the condition was determined and corrective action taken to preclude repetition related to a contractors non-compliance with site procedural requirements. The corrective actions include developing additional training and provisions to provide additional contractor oversight. This finding was entered into the licensees corrective action program as Condition Reports CR-WF3-2012-03769 and CR-WF3-2012-03772. The failure to determine the cause of a significant condition adverse to quality and take corrective action to preclude repetition was a performance deficiency. The performance deficiency was more than minor because if left uncorrected, it could lead to more significant consequences; therefore, it is a finding. Specifically, failure to determine the cause of a significant condition adverse to quality and take corrective action to prevent recurrence can result in recurrence of the condition. In accordance with NRC Inspection Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, the issue was determined to affect the Initiating Events Cornerstone. In accordance with NRC Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings at Power, the issue was determined to have very low safety significance (Green) because the finding did not cause a reactor trip and the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition. This finding had a cross-cutting aspect in the human performance, work practice component, in that the licensee failed to follow guidance in the root cause evaluation procedure when developing appropriate corrective actions to prevent repetitione corrective actions to prevent repetition
