Content:
NRC staff’s review of applications by including conceptual designs in the DCDs that offer a more comprehensive design perspective; these conceptual designs typically include portions of the balance of plant of the nuclear facility. However, because the conceptual portions of the design are not certified, the COL applicant needs to address them. The NRC does not consider replacement of the conceptual design information with actual design information to be a departure from the DC because the conceptual design was not certified. However, for those instances in which the actual design information differs from the conceptual design information, the COL applicant should explain how these differences will affect the NRC’s evaluation of the certified design and the design PRA, as applicable. The COL applicant should provide information to address the conceptual design information from the referenced DC in FSAR Chapter 1 and applicable FSAR sections. The level of detail needed for the site-specific designs that replace conceptual designs should be consistent with the level of detail provided in the DCD for the non-conceptual (or specific) designs and should be sufficient to resolve all safety issues. Departures from the Design Certification A departure is a plant-specific deviation from design information in a DCR. Section IV of appendices A through E to 10 CFR Part 52 codifying the certified designs requires a COL applicant referencing a certified design to incorporate by reference, as part of its application, the applicable appendix. A COL applicant referencing a DC may make departures from the design as provided in 10 CFR 52.63 and 10 CFR 52.93 and Section VIII of the referenced appendix to 10 CFR Part 52 that contains the DCR. D reference to The COL applicant requesting a departure that requires NRC approval, consistent with Section VIII of the relevant appendix to 10 CFR Part 52, should identify and discuss the departure in Part 7 of the application and should
