sly to supply all or part of the system’s minimum load (DOE/EIA’s “Electric Power Industry Terms and Definitions,” (Ref. 95)). Baseload power plants typically have annual load capacity factors that exceed 75 percent, but usually operate 90 to 98 percent of the time (“How to Compare Power Generation Choices” in Renewable Energy World North America (Ref. 96)). DG-4026, Page 136 Figure 9-1. Site-Selection Process The ER should include the following information: • A description of the ROI, candidate areas, potential sites, and candidate sites. If any potential or candidate sites have been designated by a governmental agency as an acceptable site for a new nuclear power plant, this information should be included in the ER. • Selection procedures for the ROI, candidate areas, potential sites, candidate sites, and the proposed site. • The basis for establishing the geographical scope of the ROI. • Factors considered at each level of the selection process, parameters by which these factors were measured and weighted, and criteria used to define levels of acceptability (e.g., numerical limits or decision standards). • Methodologies used in the potential and candidate site screening process, including (when used) factors such as (1) importance factors, (2) preference functions, (3) utility functions, (4) weighting factors, (5) ranking scales, (6) scoring schemes, (7) rating systems, and (8) sensitivity analyses. • For each alternative site, reconnaissance-level information should be included in the ER for the same impact categories used for the proposed site (see Chapters 4 and 5). While the ER summarizes the process used to select the proposed site, the NRC staff will need to know the details of the process, which is typically described in a more detailed site-selection report prepared by or for the applicant. If such a report was prepared, it should be provided to the NRC staff at the time the application is submitted to support the staff’s review.
