Finding

Title

Emergency service water non-conformance not identified in the corrective action program

Description

The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, when Exelon did not promptly identify or correct a condition adverse to quality. Specifically, Exelon did not identify and correct misaligned flanges between the D emergency service water pump and the associated discharge pipe during inspection activities in 2008 and subsequent maintenance activities in 2013. The misalignment of the flanges caused the expansion joint being installed in a configuration which exceeded design criteria of the emergency service water pump. Exelon entered this issue into the corrective action program for resolution as issue report (IR)1481670. This finding is more than minor because it is associated with the design control attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences. This issue was also similar to Example 3j of NRC IMC 0612, Appendix E, Examples of Minor Issues, because the condition resulted in reasonable doubt of the operability of emergency service water system and additional analysis was necessary to verify operability. The inspectors evaluated the finding using IMC 0609, Appendix A, and determined this finding was a deficiency affecting the design or qualification of a mitigating SSC, where the SSC maintained its operability or functionality. Therefore, inspectors determined the finding to be of very low safety significance (Green). This finding has a cross-cutting aspect in the area of Problem Identification and Resolution, Corrective Action Program, because Exelon did not identify the issue associated with the non-conforming emergency service water expansion joint in a timely manner.
