been provided with special design features to mitigate the effects of failures. Radionuclide concentra- tions at the nearest potable water supply were found to be acceptable. The basis for acceptance has been that the staff's review shows that the postulated failure of a tank and its associated components would not result in radionuclide concentrations in excess of 10 CFR Part 20, Appendix B, Table II, Column 2 at the water source(s) noted above. For those cases where special design features were incorporated to mitigate the consequences of a failure of a tank and the associated components, the following type of statement is made: Tanks for which special design features were incorporated to mitigate the consequences of failures such as steel liners or walls or dikes sur- rounding the failed components and overflow provisions were evaluated and found to be acceptable. The basis for the staff's acceptance was the capability of these design provisions to prevent the release of radio- activity from entering a potable water supply system. Therefore, the staff concludes that the design provisions incorporated by the applicants to mitigate the effects of a tank and its associated components failure involving radioactive liquids are acceptable. 15.7.3-3 Rev. 2 - July 1981 In any case, the staff concludes that the postulated failure of a tank and its associated components has been evaluated and the design is acceptable and meets the requirements of General Design Criterion 60 for the control of releases of radioactive materials to the environment. This conclusion is based on the following: The applicant has met the requirements of General Design Criterion 60 with respect to the control of releases of radioactive materials to the environment by providing controls to reduce the potential impact of the failure of a radioactive liquid-containing tank and its associated components. Such a release will not result in concentrations exceeding the limits of 10 CFR Part 20, Appendix
