fety Issues (Formerly entitled "A Prioritization of Generic Safety Issues"),” current on the date 6 months before application and that are technically relevant to the design; (2) demonstrate how the operating experience insights have been incorporated into the plant design; and, (3) provide information necessary to demonstrate compliance with any technically relevant portions of the Three Mile Island (TMI) requirements set forth in 10 CFR 50.34(f), except paragraphs (f)(1)(xii), (f)(2)(ix), and (f)(3)(v), as stipulated under 10 CFR 52.47(a)(21), 10 CFR 52.47(a)(22), and 10 CFR 52.47(a)(8), respectively. For COL applicants, the parallel requirements, with exception to the provision on operating experience and plant design, are described in 10 CFR 52.79(a)(20) and 10 CFR 52.79(a)(17). These cross-cutting review areas should be addressed by the reviewer for each technical subsection and relevant 11.1-13 Revision 4 – January 2016 conclusions documented in the corresponding section of the staff’s Safety Evaluation Report (SER). 3. In the review of the mathematical models and parameters given in the application to calculate primary and secondary coolant concentrations, the reviewer compares parameters and calculations given in the application with the models and parameters given in NUREG-0016, NUREG-0017, or ANSI/ANS 18.1-1999, modified as necessary to reflect the design and operating parameters of the proposed reactor design. If the application includes models or parameters to estimate reactor coolant and steam concentrations that differ from the guidance, the parameters and calculations used should be substantiated by the applicant. The preferred method of substantiation is by presentation of operating data from similar reactors with information justifying the basis 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
