e are several possible scenarios for SMR applications. The information provided in the ER would depend on the types of applications submitted and the timing of actions proposed in the application. The most likely licensing scenarios for SMR applications are described below. C.2 Scenario 1: All Modules in One Application A potential applicant could request licenses for multiple modules installed over time. Under this scenario, the proposed action would include licenses for all the modules that would be constructed at the proposed site. The applicant should provide a schedule as to when each module would be constructed and operated to inform the NRC staff of the timing of impacts. The information submitted to support the NRC’s cumulative impact analysis should follow the guidance in Chapter 7 of this RG. In Chapter 9 of the ER, the analysis should compare the impacts of constructing and operating all of the modules at the alternative sites to the cumulative impacts of Chapter 7 of the ER to determine if an environmentally preferable or obviously superior site exists. The information submitted by the applicant to support the need-for-power analysis, alternative energy analysis and benefit-cost analysis should be based on an accounting of the full capacity of all the modules for which licenses are being requested. DG-4026, Appendix C, Page C-2 C.3 Scenario 2: Two or More Separate License Applications (Subsequent application considered an expansion of the existing site) An applicant could request licenses for one or more modules and inform the NRC that it intends to request licenses for additional modules in the future. Under this scenario, the proposed action would include only the modules for which licenses are requested. The applicant should provide sufficient information to allow the NRC to determine whether the additional modules are reasonably foreseeable for the purposes of evaluating cumulative impacts. For the additional modules to be treated as reasonably
