s later disbanded in 2012 upon the issuance of the first two COLs that referenced the AP1000 DC. The DCRA evolved through DCWG meetings and public meetings in which the details of how S-COL applicants would reference previous staff decisions on the standard content of an R-COL were developed. The industry and specifically the DCWGs proposed the original development of LMA. NuStart presented referencing approaches to the AP1000 Advisory Committee on Reactor Safeguards subcommittee which can be found in “AP1000 Advisory Committee on Reactor Safeguards subcommittee meeting transcript”, October 2007 (Ref. 80) and clarified that having a single R-COL was preferable for the AP1000 because of the challenge of referencing standard content in multiple parallel COLA reviews. The decision to restrain referencing COLs other than a COLA identified as an R-COL application by a DCWG was primarily to avoid confusion and problems associated with multiple COLAs referencing each other.5 Alternatively, NuStart, Dominion Virginia Power, and Entergy indicated initially that, for the ESBWR, standard content would be developed without identifying an R-COL application (Ref. 81) and described planning for submitting the two first COLAs to reference the EWBWR simultaneously. NuStart proposed the use of endorsement letters from S-COL applicants in an AP1000 DCWG Category 1 public meeting on October 9, 2008 (Ref. 82). In addition to the evolving practices of COL applicants and DC vendors, the NRC staff has expanded the use of the DCRA to other areas with essentially identical information for regulatory purposes. FSERs on S-COLs have relied on and directly referenced earlier FSERs for COLAs incorporating by reference the same design. This practice has not been restricted to referencing standard 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
