On November 24, 2015, the NRC issued a Notice of Violation, characterized as Severity Level III, to Entergy Nuclear Operations, Inc. for a violation of 10 CFR Part 50.9, "Completeness and accuracy of information." This violation involved the failure to provide information to the Commission that was complete and accurate in all material respects. Specifically, the licensee submitted Letter No. PNP 2014-015 to the NRC, which inaccurately stated the effective full power years for which the ASME Code acceptance criteria would be met at Palisades Nuclear Plant. The NRC staff used this information to grant the licensee's proposed alternative to regulatory requirements. On May 22, 2015, the licensee submitted Letter PNP 2015-037 with a corrected analysis. The error in letter PNP 2014-015, and resultant change to the analysis results in letter PNP 2015-037, represented a significant reduction in the time to reach the ASME Code acceptance criteria limits. Therefore, the information is considered material to the NRC for review of the proposed alternative to regulatory requirements in letter PNP 2014-15.
