drain provisions. The basis for the staff's acceptance is the capability of design features (Note: Staff should list and describe specific features in SER) to prevent the release of radioactivity from entering a surface water body or groundwater in unrestricted areas using durable and passive features requiring no operator interventions. Therefore, the staff concludes that the design provisions incorporated by the applicant are acceptable and that they provide reasonable assurance in mitigating the effects of the failure of a tank and components, as described in the application. 3. The review confirmed the applicant’s approach to modeling the transport of radioactivity in surface water or groundwater starting from the building housing the assumed failed tank and components to the nearest point of entry in unrestricted areas. For the reasons presented in SER Section 2.4.13, the review concludes that the identification and consideration of the potential effects of postulated releases of radioactive liquid effluents in groundwater and surface water in the vicinity of the site are acceptable and meet the requirements of 10 CFR Part 50, Appendix A, GDC 2 and GDC 61 and 10 CFR 100.10(c) or 10 CFR Part 52 and 10 CFR 100.20(c), and are consistent with the guidance in SRP Section 2.4.13. 4. The staff concludes that (1) the postulated failure of a tank and components has been evaluated, (2) the design features are acceptable and meet the requirements of 10 CFR Part 50, Appendix A, GDC 60 and GDC 64 for controlling and limiting releases of radioactive materials to the environment, and (3) the design features provide an adequate level of safety during normal reactor operation, including anticipated operational occurrences. Plant facility structures and system design features described in the application provide reasonable assurance that the assumed release will not result in radionuclide concentrations in surface water or groundwater exceeding the SRP acceptance criterion of
