Title | Licensee-Identified Violation |
Description | A violation of 10 CFR 50.59 was identified in that NextEra improperly made a change to the UFSAR using the 10 CFR 50.59 process that required NRC review and approval prior to implementation. Specifically, in 2010, NextEra changed a graph in the UFSAR used to determine the reactivity in a fuel bundle based on burn-up so that the fuel could be safely placed in the spent fuel pool. This change to the UFSAR was made using the 10 CFR 50.59 process. However, because this same graph is in the Technical Specifications, the 10 CFR 50.59 process could not be used and a licensee amendment under 10 CFR 50.90 was required. Traditional enforcement applied because the change impeded the regulatory process. The issue is more than minor because the change was made without NRC review and approval prior to implementation. The issue was determined to be of very low safety significance (Green) using IMC 0609, Attachment 4, because it was a spent fuel pool issue that did not result in a loss of SFP cooling, did not involve a fuel handling error, and did not result in a loss of SFP inventory. Subsequent to making the change to the UFSAR, NextEra submitted a license amendment request (LAR 11-04) in January 2012 to obtain approval for the change. NextEra entered the issue into the corrective action program (CR 1744734) for evaluation and resolution. |
