ma DAEC-1 Liquid waste treatment with the evaporator at DAEC has been shown to be neither cost-beneficial nor necessary to comply with 10CFR50 Appendix I, Section II Consequently, liquid radweste treatment to achieve an activity concentration below 0.01 pCi/mi in liquid effluent is not justified.
3.14.E and 4.14 E BASES I
1.
Liquid Hold-Up Tanks I
The tanks listed in the specification include all liquid radwaste tanks in the Low-Level Radwaste Processing and Storage Facility (LLRP5F).
Because the LLRPSF is not seismically designed, these tanks are considered as outdoor tanks that are not surrounded by liners, dikes, or walls capable of holding the tank contents.
Restricting the quantity of radioactive material contained in the specified tanks provides assurance that in the event of an uncontrolled release of the tanks' contents, the resulting concentrations would be less than the limits of 10 CFR 20 Appendix B, Table II, Column 2, at the nearest potable water supply in an unrestricted area.
