| Title | Failure to Determine the Correct Cause and Prevent Recurrence for a Significant Event |
| Description | A Green, self-revealing finding was identified for the licensees failure to comply with the standards established in their corrective action program (CAP) to determine the correct cause and take corrective action to prevent recurrence (CAPR) for a significant event, specifically, an automatic reactor trip following the failure of a Unit 2 C reactor coolant loop isolation valve. The licensee entered this issue into their CAP as condition report 412345. The inspectors determined that the failure to determine the correct cause and take corrective action to prevent recurrence for a significant event was contrary to the requirements of the licensees CAP procedures and was, therefore, a performance deficiency. The inspectors reviewed IMC 0612, Appendix B, and determined the performance deficiency was more than minor because it adversely affected the equipment performance attribute of the Initiating Events 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 reviewed IMC 0609, Attachment 4 and determined that the finding was of very low safety significance, or Green, because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available. The cause of this finding involved the cross-cutting area of problem identification and resolution, the component of operating experience, and the aspect of implementing operating experience, P.2(b), because the licensee failed to implement and institutionalize operating experience. |
