Content:
containment that could contain radioactive liquids. A single failure of these tanks could release radioactive liquids to surface water or ground water and potentially impact public health and safety. Compliance with GDC 60 and GDC 64 requires, as addressed in SRP Section 11.5 in demonstrating compliance with liquid effluent releases, that the nuclear power plant design shall include the means to control and monitor releases of radioactive materials in gaseous and liquid effluents and provide adequate safety during normal reactor operation, including anticipated operational occurrences. Meeting these criteria provides reasonable assurance that releases of radioactive materials due to a single failure of liquid-containing tanks and components outside of containment during normal operations or anticipated operational occurrences will not result in usable water concentrations and doses to members of the public exceeding the acceptance criteria identified above. 2. Conformance with the acceptance criteria of 100 mrem (1 mSv) at the point of entry into the nearest existing or a known future water supply requires that radioactive materials contained in a failed tank and component do not result in radionuclide concentrations in excess of those values that would yield doses in excess of 100 mrem (1 mSv) for all potential exposure pathways, as described by the applicant. A single failure of tanks and components could release radioactive liquids to surface and ground water and potentially impact the public. GDC 60 and GDC 64 require that the nuclear power unit design include the means to control and monitor the release of radioactive materials in gaseous and liquid effluents, and 10 CFR Part 20 (Appendix B, Table 2, Column 2) provides ECLs in the unlikely event of a single failure of liquid- containing tanks outside of containment. Meeting these criteria provides assurance that releases of radioactive materials due to a postulated single failure of liquid-containing tanks and
