The team identified a Green noncited viola … The team identified a Green noncited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, which states, in part, that measures shall be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures, and instructions. Specifically, prior to September 28, 2011, the licensee failed to assure that design basis information associated with loading the auxiliary component cooling water pumps on the Class 1E Bus was correctly translated in various design basis calculations. This finding was entered into the licensees corrective action program as Condition Reports CR-WF3- 2011-06737 and CR-WF3-2011-06808. The team determined that the failure to verify the adequacy of the design for loading the auxiliary component cooling water pumps on the Class 1E Bus in various design basis calculations was a performance deficiency. This finding was more than minor because it was associated with the design control attribute of the Mitigating Systems Cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the inadequate design calculations could have prevented continued operation of the emergency diesel generator under degraded voltage, short circuit, and increased fuel oil consumption conditions. In accordance with NRC Inspection Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the issue was determined to have very low safety significance (Green) because it was a design deficiency confirmed not to result in loss of operability or functionality. Specifically, the licensee revised the associated calculations to include the required 295 brake horsepower value and reanalyzed for verification of operability. This finding did not have a crosscutting aspect because the most significant contributor did not reflect current licensee performanced not reflect current licensee performance
