| Title | Failure to Follow Station Process for Root Cause Evaluation |
| Description | The inspectors identified a Green finding for the failure of station personnel to follow procedures to implement root cause evaluations. Specifically, approximately one third of the root cause evaluations reviewed by inspectors resulted in a probable cause with further information needed to validate the cause. Of this subset, eighty percent of the evaluations did not adhere to station processes. The failure of station personnel to follow station procedures to implement root cause evaluations was a performance deficiency. The performance deficiency was more than minor, therefore a finding, because if left uncorrected the performance deficiency could become a more significant safety concern in that significant conditions adverse to quality could reoccur prior to the implementation of appropriate corrective action. The finding is associated with multiple cornerstones, though it is most closely associated with the Mitigating Systems Cornerstone and the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the significance of the issue under the Significance Determination Process, as defined in Inspection Manual Chapter 0609.04, Initial Characterization of Findings, and 0609, Appendix A, The Significance Determination Process (SDP) for Findings at-Power. The inspectors concluded the finding was of very low safety significance (Green) because all questions in Exhibit 2 could be answered in the negative. The inspectors determined that the finding had a consistent process cross-cutting aspect in the area of human performance because the licensee did not use a consistent and systematic approach when making decisions (H.13). |
