F.3 Potential Plant ImprovementsF.3.1 Process for Identifying Potential Plant Improvements F.3.2 Review of Entergy's Process In response to an NRC staff RAI, Entergy indicated that the ER statement regarding the results of the SAMA analysis of 13 BWR plants were reviewed was incorrect. It was found that the analysis for one of the 13 plants listed in the ER had not been reviewed. Entergy concluded that since so many SAMAs had already been considered, the review of this added plant would not be expected to add a new retained SAMA (Entergy 2017b).
