The radionuclide concentrations at the nearest potable water supply are calculated by HGEB using the values of hydrological parameters they developed with the guidance in SRP Section 2.4.12 and using the ETSB calculated radionuclide concentration in failed components. HGEB will transmit a summary of the results to ETSB to permit ETSB to complete the safety evaluation report. 3. Compliance with the acceptance criteria given in subsection II will be determined by ETSB based on the HGEB calculation of radionuclide concentrations at the nearest potable water supply. 4. The ETSB will review the technical specification limiting the curie content of liquid containing tanks to ensure that the technical specifi- cation is consistant with the safety evaluation. The curie content is based on that quantity which would not exceed the concentration limits of 10 CFR Part 20, Appendix B, Table II, Column 2 at the nearest potable water supply if the tank and components should fail, or will be limited to 10 curies in any mobile or portable tank used more than one calendar quarter. IV. EVALUATION FINDINGS If the ETSB confirms that the consequences of liquid-containing tank failures would be acceptable according to the criteria stated in subsection II of this SRP section, conclusions of the following type are provided for the staff's safety evaluation report: The scope of the review included the calculation of radionuclide concentrations in the applicable failed components based upon the expected fuel failure rate for the plant and the effect of site hydrology for those systems that have not 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
