odules and the locations of environmental interfaces. The site layout and plant description should clearly describe the scope of the project as proposed in the license application, including the total number of modules requested to be licensed and the proposed operational date for each module. The applicant should also include any information known about planned installation of future units. C.7.4 Chapter 4: Construction Impacts at the Proposed Site In general, the applicant should follow the guidance in Chapter 4 of this RG for preparing a discussion of construction impacts. However, because modules may be installed over time to meet the demand for electricity, the applicant should describe and evaluate construction impacts over the time frame specified in the application. As part of the proposed action, the applicant may install infrastructure and facilities that could be used to support additional reactor modules. These activities should be evaluated as part of the construction impact analysis in the ER. C.7.5 Chapter 5: Operational Impacts at the Proposed Site In general, the applicant should follow the guidance in Chapter 5 of this RG for preparing a discussion of the operational impacts. However, because modules may be installed over time to meet the demand for electricity, the applicant should evaluate operational impacts over the time frame specified in the application. Specific SMR designs may have features that differ from LLWR designs. For example, dry cooling may be proposed, resulting in significantly less consumptive water use. In these cases, an applicant would not need to evaluate impacts from entrainment or impingement, or impacts from thermal discharges to a waterbody. The ER should include a short statement that environmental impacts in these areas are not expected because of the design features of the proposed plant. C.7.6 Chapter 6: Fuel Cycle, Transportation, and Decommissioning The applicant should follow the guidance in Chapter 6 of this RG
