the parameters and calculations used should be substantiated. The preferred method of substantiation is by presentation of operating data from similar reactors. 2. The reviewer performs an independent calculation of the primary and secondary (PWR) coolant concentrations using the guidance provided in ANSI/ANS 18.1-1999. 3. In the calculation, the reviewer will use the applicant's values as given in the SAR for the following parameters: design core thermal power level, steam flow rate, coolant mass, and coolant purification rates. Note: The source terms referenced in the section are used for both the review of the SAR and for the staff’s environmental impact statement. 11.1-7 Revision 3 - March 2007 4. 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 applicable to the Commission’s review of an ESP application. 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 review of data parallel that used for a CP review. For review of an ESP application, staff will evaluate the postulated design parameter associated with the normal operational source term. 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 on the early site permit. B. Standard Design Certification Reviews. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface
