The inspectors identified a NCV of 10 CFR … The inspectors identified a NCV of 10 CFR Part 50, Appendix B, Criterion III, Design Control, having very low safety significance (Green) related to whether the equipment in the low pressure coolant injection (LPCI) corner rooms would remain within environmental qualification limits during a design basis loss-of-coolant-accident. Specifically, the licensees heat-up calculation contained discrepancies and failed to evaluate the worst case effects post-extended power uprate when determining the heat-up in the LPCI corner rooms. This finding was entered into the licensees corrective action program as AR00763663, AR00742158, AR00883207, AR01055863, and AR01060243, and an operability call performed by the licensee concluded that there are sufficient conservatisms in the calculation that equipment in the corner rooms remained operable. The finding was more than minor because it was associated with the attribute of design control, which affected the Mitigating Systems Cornerstone objective of ensuring the availability and reliability of safety-related systems. This finding is of very low safety significance (Green) because the design deficiency was confirmed not to result in loss of operability or functionality. The inspectors did not identify a cross-cutting aspect associated with this finding because this was a legacy design issue and, therefore, was not reflective of current performance.was not reflective of current performance. +
