| Title | Failure To Promptly Identify And Correct A Pressure Boundary Through Wall Leak On The 3A Ccw Pump Casing Vent Pipe |
| Description | The NRC identified a non-cited violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for the licensees failure to identify and correct a through wall pressure boundary leak on the 3A component cooling water (CCW) pump casing vent piping that affected system operability. The inspectors determined that the licensees failure to identify and correct a through wall leak on an ASME Code Class pressure boundary was a performance deficiency. The condition was entered in the licensee corrective action program (CAP) as action request 01883690 and the pipe was replaced. The performance deficiency was determined to be more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated September 7, 2012, because it was associated with the mitigating systems cornerstone attribute of equipment performance and adversely affected the cornerstone objective to ensure the reliability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the inspectors determined that the licensees failure to identify a system pressure boundary leak precluded evaluations and repairs necessary to assure the reliability of the component cooling water system. The inspectors evaluated the finding using IMC 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, Tables 2 and 3, dated June 19, 2012, and Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 2 for the Mitigating Systems Cornerstone, dated June 19, 2012. The inspectors answered yes to the Exhibit 2 question A.1 because the system maintained its functionality. As a result, the inspectors determined the finding to be of very low safety significance (Green). This finding was associated with a cross-cutting aspect in the corrective action program component of the problem identification and resolution area. Specifically, the licensee failed to consider the potential for system pressure boundary leakage when evaluating the operability of the component cooling water system |
