st-case diversion, migration, or realignment scenario at the proposed plant site. 6. Review Procedures Specific to 10 CFR Part 52 Application Type A. Early Site Permit Reviews Subpart A to 10 CFR Part 52 specifies the requirements and procedures applicable to the Commission’s review of an ESP application for approval of a proposed reactor site. Information required in an ESP application includes a description of the site characteristics and design parameters of the proposed site. The scope and level of detail of the review should be similar to that for a CP review. In the absence of certain circumstances, such as a compliance or adequate protection issue, 10 CFR 52.39, “Finality of early site permit determinations,” precludes,”p the staff from imposing new site characteristics, design parameters, or terms and conditions on the early site permit at the COL stage. Accordingly, the staff should ensure that all physical attributes of the site that could affect the design basis of SSCs important to safety are reflected in the site characteristics, design parameters, or terms and conditions of the ESP. B. Standard Design Certification Reviews DC applications do not contain general descriptions of site characteristics because this information is site-specific and will be addressed by the COL applicant. However, pursuant to 10 CFR 52.47(a)(1), a DC application must include information on the site parameters postulated for the design. Site parameters associated with this SRP section are reviewed, as applicable, to verify that: i. The postulated site parameters are representative of a reasonable number of sites that have been or may be considered for a COL application; ii. The appropriate site parameters are included as Tier 1 information. This convention has been used by previous DC applicants. Additional guidance on site parameters is provided in SRP Section 2.0; 2.4.9-14 Draft Revision 4 – September 2018 iii. Pertinent parameters are stated in a site parameters
