for any adjustments taking into account the design features of plant-specific conditions. 4. The reviewer performs an independent calculation of the primary and secondary coolant concentrations using the guidance of NUREG-0016, NUREG-0017, or ANSI/ANS 18.1-1999, modified as necessary to reflect the parameters of plant-specific conditions. The applicant should provide sufficient information for the staff to conduct an independent evaluation of the applicant’s use of alternative code parameters. The review should consider differences in calculation methods and selection of code parameters chosen because of differences in design and operating features of the proposed design when compared to either code. 5. In the calculation, the reviewer will use the applicant's values as given in the application for the following key parameters: design core thermal power level, steam flow rate, mass of primary coolant mass, mass of liquid in reactor vessel, mass of water in each steam generator and number of steam generators, steam generator blowdown rates, primary coolant letdown rates, and coolant purification rates, among others. RG 1.112 (Appendix A for BWRs, Appendix B for PWRs), NUREG-0016, or NUREG-0017 provide guidance on plant data needed to develop input parameters for either code. The staff may use alternative parameters for the purpose of assessing whether the applicant’s values provide a reasonable level of conservatism in assumptions and results. Note: The source terms referenced in this section are used for both the review of the application and environmental report, and for the staff’s preparation of the SER and environmental impact statement. 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 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
