ability of the design change is based on the TEDE criteria for the reanalyzed LOCA and FHA. As the remaining offsite and control room accident analyses are unaffected, the previous acceptance criteria continue to apply to those analyses. (b) In the previous example, what would be the result be if the modification was to control room habitability systems instead of the SGTS? Answer: Since the control room habitability criterion applies to all accident conditions, the licensee must demonstrate that control room doses will meet the TEDE criterion for all accidents. Once the application is approved, the design bases for these systems would incorporate the TEDE criterion. In either case, the reviewer should ensure that the licensee’s submittal and the staff’s SER clearly identify the acceptance criteria for the 15.0.1-10 Rev. 0 -- July 2000 accident, or the component, that will become part of the plant design basis. c. Once an implementation of an AST is approved, the licensee may subsequently submit additional license amendment requests. The AST characteristics and the TEDE criteria incorporated into the design basis by previously approved AST applications are the bases for reviews of subsequent licensing actions. The reviewer should ensure that these subsequent requests are consistent with the design basis AST implementation. 3. The reviewer should ensure that the licensee has performed sufficient analyses to meet the staff’s expectation that all significant potential impacts have been identified and evaluated. The reviewer should determine if the application adequately characterizes the radiological and nonradiological impacts of the proposed plant modifications in the context of the proposed AST. The reviewer should ensure that the analyses described by the licensee have the scope and depth to adequately evaluate the impacts of the change. All affected design basis analyses should be updated. An analysis is considered to be affected if the proposed modification
