considered final. If a COL applicant then defers making changes until after issuance of the COL, the NRC may need to review a number of departures and LARs to support the eventual construction of the facility. In addition, resolving constructability issues encountered during construction or startup issues immediately after the 10 CFR 52.103(g) finding by the Commission may result in additional post-licensing departures, exemption requests, or LARs. The DCRA has focused on referencing standard content that was established during the review of a COLA. There is no regulatory requirement that would restrict a COL applicant from referencing either post-licensing departures and changes or LARs. As discussed in regard to LMA in this regulatory topic, refined LMAs could be used for efficient referencing of post-licensing departures. The semiannual reporting of changes, tests, and experiments required by 10 CFR 50.59, “Changes, Test and Experiments,” and departures under Section VIII of the relevant appendix in 10 CFR Part 52 (e.g., the Virgil C. Summer Nuclear Station letter dated August 1, 2016 (Ref. 75) provides detailed information that may be useful to applicants. Information on post-licensing LARs is readily accessible and could also be useful in the development of departures for a COLA. LARs, such as the letter dated December 17, 2015, from South Carolina Electric & Gas Company requesting a license amendment and exemption (LAR 15-15, “Radiologically Controlled Area Ventilation System (VAS) Design Changes” (Ref. 76), provide detailed information that could be used for a departure in future COLAs or in support of similar LARs if identified after an S-COL application’s freeze point. Supplement to C.2.7 —Background Information on the History of the Design Centered Review Approach Constraints on applicants, the NRC staff, and public resources were an important impetus for RIS 2006-06 based on an unprecedented increase in projections of near-term COLAs related
