ppendix I to 10 CFR Part 50. Section II.D of Appendix I requires that the applicant demonstrate that the plant design includes all items of reasonably demonstrated technology which, when added to RMWS sequentially and in order of diminishing return, will effect a reduction in releases of radioactive materials and cumulative population doses within an 80-km (50-mile) radius of the plant. 6. Liquid and gaseous effluent concentration limits at the boundary of the unrestricted area do not exceed the values specified in Table 2 of Appendix B to 10 CFR Part 20 and Note 4 for radionuclide mixtures. 7. The primary and secondary coolant and steam source terms, and those of associated plant systems and components, used in characterizing liquid and gaseous effluents, confirm that resulting doses comply with the design objectives in unrestricted areas as set forth in Appendix I to 10 CFR Part 50, Sections II.A to II.C. 8. In evaluating the coolant source terms, the applicant should provide the relevant information in the application as required by 10 CFR 50.34a(b)(3), 10 CFR 50.34a, and 10 CFR 52.79(a)(3). The FSAR should include the data listed in Appendix A (BWRs) and Appendix B (PWRs) of RG 1.112 in order to calculate releases of radioactive materials in liquid and gaseous effluents. An acceptable method for satisfying the criteria given in items 1 through 5 (above) consists of using the PWR-GALE code or BWR-GALE code, as adjusted to reflect specific design features. Differences in design features and 11.1-10 Revision 4 – January 2016 operating characteristics should be evaluated and used to make specific adjustments to the parameters used in NUREG-0016, NUREG-0017, or ANSI/ANS 18.1-1999. Differences may also exist in the operational configuration and sequence of treatment among RWMS equipment for various process streams and in treating effluents prior to being released to the environment. Whenever adjustments are made to parameters used in the PWR-GALE or BWR-GALE code,
