t be demonstrated at the ESP stage. However, the ESP SSAR should include this information in order to avoid providing additional atmospheric dispersion estimates at the COL or CP stage. In the absence of certain circumstances, such as a compliance or adequate protection issue, 10 CFR 52.39 precludes the staff from imposing new site characteristics, design parameters, or terms and conditions on the early site permit at the COL stage. Accordingly, the reviewer 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 early site permit. 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 applicant must provide site parameters postulated for the design. The reviewer verifies that: 1. The postulated site parameters are representative of a reasonable number of sites that have been or may be considered for a COL application; 2.3.5-8 Revision 3 - March 2007 2. 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; 3. Pertinent parameters are stated in a site parameters summary table; and 4. The applicant has provided a basis for each of the site parameters. The staff should ensure that the DC applicant has included the maximum annual average site boundary χ/Q value in the list of site parameters. c. Combined License Reviews For a COL application referencing a certified standard design, NRC staff reviews that application to ensure that sufficient information is presented to demonstrate that the characteristics of the site fall within the site parameters specified in the DC rule. Should the
