| Title | Failure to Classify the Internal Piping in the Auxiliary Feedwater Pump Room Coolers as ASME Code Class 3 Piping |
| Description | The inspectors identified a finding of very low safety significance (Green) with an associated non-citied violation of 10 CFR 50, Appendix B, Criterion III, for failure t
correctly translate regulatory requirements related to the American Society for Mechanical Engineers (ASME) code class boundary to the AFW pump room cooler. Specifically, the licensee failed to classify the internal piping in the AFW pump room coolers as ASME code class 3 piping when it should have been classified as such. As immediate action, the licensee declared the affected room cooler inoperable and repaired the leak. Because of low room temperature, the supported TDAFW pump remained operable. The inspectors determined that the failure of the licensee to correctly translate regulatory requirements for a safety related system into a drawing, as described in 10 CFR 50, Appendix B, Criterion III, Design Control, was a performance deficiency warranting further evaluation in the Significance Determination Process (SDP). The issue screened as more-than-minor because it adversely affected the Design Control attribute of the Mitigating Systems cornerstone. Using Appendix A of IMC 0609, the inspectors concluded the finding was of very low safety significance, Green, because the supported AFW system remained operable. Because the performance deficiency occurred in 2000, the finding does not reflect current performance and no cross-cutting aspect exists. Because the violation was of very low safety significance and promptly entered into the licensees Corrective Action Program (CAP) (AR 2014-7570), and the violation was not repetitive or willful, this violation is being treated as an NCV, consistent with Section of 2.3.2 of the NRC Enforcement Policy. |
