ferences a DC complies with both the rule certifying the design and the DCD. A COL applicant or licensee that wishes to make a change to the DCD Tier 1 or Tier 2 information should do so in accordance with Section VIII of the applicable DCR appendix to 10 CFR Part 52. In accordance with 10 CFR 52.47(a), the COL applicant should submit a plant-specific FSAR. The FSAR is similar to the design-specific DCD required by a COL applicant that incorporates by reference a DC that includes the Tier 2 design information as modified by the addition of the site-specific information, approved Tier 2 changes, and the approved departures and/or exemptions from Tier 1. Although not a requirement, COL applicants that do not incorporate by reference a DC may also develop detailed design descriptions that include design bases, tables, and figures specifically for use and reference by the COL ITAAC. In this case, the COL applicant should call its descriptions “ITAAC Design Descriptions” to distinguish these design descriptions from those included in the Tier 1 document for a certified design. These ITAAC design descriptions should be separate, but should be derived from the detailed design information in the FSAR portion of the COLA. The proposed COL ITAAC may reference the specific sections, tables, and figures in the ITAAC design descriptions for verification of the design requirements and commitments. However, the Tier 1 and Tier 2 designations do not apply to a COLA that does not reference a DC because certified design information is subject to a different change process than that of a COL (i.e., Section VIII of the applicable appendix to 10 CFR Part 52). The COL applicant should include the proposed ITAAC in Part 8 of the COLA. If the COLA references a DC, the COL applicant may (1) include the entirety of Tier 1 information in Part 8 of the COLA or, alternatively, (2) include the Tier 1 design descriptions, significant interface requirements, and significant site parameters in
