on the docket and the staff’s evaluation of these data. The following information should be included as applicable to the particular AST implementation. These conclusions should be combined with the conclusions of other reviewers with regard to nonradiological aspects of the evaluation as applicable. 1. The AST implementation should be described in sufficient detail to reasonably document the approved design basis, as modified. This step is particularly important for selective implementation applications. Cross-references to information submitted on the docket should be used when available in the interest of minimizing unnecessary repetition. 2. The regulatory mechanism, for example, 10 CFR 50.67, under which the change is being considered, is identified. Any regulatory exemptions, related technical specification changes, or licensee commitments are identified. 3. The licensee’s supporting analyses and conclusions are described in sufficient detail to adequately document the design bases. Key analysis assumptions and inputs, analysis methods, and postulated doses should be included. 4. The staff’s evaluation of the licensee’s submittal, including the proposal, supporting evaluations, and conclusions drawn, should be described. Independent analyses prepared by the staff, if any, should be described. Essential analysis assumptions and inputs, analysis methods, and postulated doses should be included. 5. A conclusion similar to the following is to be included in the SER: The staff has reviewed the alternative source term (AST) implementation proposed by the <licensee> for the <facility>. The staff also reviewed the plant modifications associated with this proposed implementation. In performing this review, the staff relied upon information placed on the docket by <licensee>, staff experience in performing similar reviews and, where deemed necessary, on staff confirmatory calculations. The staff reviewed the assumptions, inputs, and methods used by <licensee> to
