of the relevant appendix to 10 CFR Part 52. The applicable DCR appendix to 10 CFR Part 52 requires COL applicants to provide a report to the NRC that contains a brief description of any plant-specific departures from the DCD with a summary of the evaluation for each departure. The DCR also requires each applicant to maintain and submit updates to its plant-specific DCD, which consists of the generic DCD and plant-specific departures. To fulfill these requirements, the applicant may provide a report separate from the FSAR with the description and evaluation for each departure and include a summary table in this section of the FSAR that lists each departure and the FSAR sections that address each departure. Sections C.1.7 and C.2.14 contain explanatory information and guidance on this topic. Variances from the Early Site Permit A variance is a plant-specific deviation from one or more of the site characteristics, design parameters, or terms and conditions of an ESP or from the SSAR. As required by 10 CFR 52.79(b), if the application’s FSAR does not demonstrate that the design of the facility falls within the site characteristics and design parameters of the ESP, the COLA should include a request for a variance that complies with the requirements of 10 CFR 52.39 and 10 CFR 52.93. In addition, the COL applicant may, at its option, request a variance from the permit terms and conditions or from the SSAR. The COL applicant requesting a variance should identify and discuss the variance in Part 7 of the application and should provide detailed and sufficient information in the FSAR to justify the variance and enable the NRC staff to resolve all safety issues pertaining to the variance. Further, the applicant should identify or uniquely designate the information provided in the application, including the FSAR, which is a variance from the ESP. In addition, 10 CFR 51.50(c)(1)(i) requires the ER to contain information to demonstrate that the design of the facility falls
