andard content in the relevant R-COL application. The FSERs for S-COL applications have instead directly incorporated excerpts from the FSERs from previous COLA reviews that the staff relied on in its analysis of the application in question. The WLS FSER directly referred to LPN as the R-COL application for several design issues that were resolved after issuance of the COLs for VEGP and Virgil C. Summer Nuclear Station because of LPN’s role as the default R-COL application that carried standard content 5 In a letter dated April 28, 2009, the NuStart Energy Development, LLC, consortium informed the NRC that it had changed the R-COL designation for the AP1000 design center from BLN, Units 3 and 4, to VEGP, Units 3 and 4 (Ref. 84). The transition of the R-COL from BLN, Units 3 and 4, to VEGP, Units 3 and 4, occurred after the issuance of the BLN, Units 3 and 4, SE with open items. Standard content material from the SE for the R-COL (VEGP) application and referenced in a later SE includes evaluation material from the SE for the BLN COLA. Similar changes relevant to the ESWBR R-COL application designation have occurred. DG-1325, Page-64 related to more recently resolved issues in Section 21.0 of the WLS FSER (Ref. 83). Various sections of the WLS FSER (e.g., Section 21.1.4) describe how the staff used material from LPN in the review of the WLS COLA, which included a comparison between the WLS and LNP FSARs and verification that site-specific differences were not relevant. The NRC’s DCRA increased efficiencies associated with standardization of license applications under 10 CFR Part 52. The development of the DCRA was partially in response to an unprecedented increase in projected licensing and DC application reviews. The DCRA has relied historically on the use of LMA of the FSAR, identification of an R-COL application that would be a carrier of “standard content” that would be shared by S-COL applications, and use of endorsement letters related to R-COL
