Design Evaluation The reviewer will evaluate the methods for demonstrating that the design bases are met. Methods include operating experience, prototype testing, and analytical predictions. Many of these methods will be presented generically in topical reports and will be incorporated in the safety analysis report by reference. A. Operating Experience Operating experience with fuel systems of the same or similar design should be described, including the maximum burnup experience. When adherence to specific
