cidental and Routine Reactor Releases for the Purpose of Implementing Appendix I,” and the LADTAP II computer code (NUREG/CR-4013) that provide acceptable methods for performing this analysis. B. In addition to 1.A, the LWMS should include all items of reasonably demonstrated technology that, when added to the system sequentially and in order of diminishing cost-benefit return for a favorable cost-benefit ratio, can effect reductions in doses to the population reasonably expected to be within 11.2-13 Revision 5 – January 2016 80 kilometers (km) (50 miles (mi) of the reactor and comply with the cost-benefit ratio of Section II.D of Appendix I. RG 1.110, “Cost-Benefit Analysis for Radwaste Systems for Light Water Cooled Nuclear Power Reactors,” provides an acceptable method for performing this analysis. C. The concentrations of radioactive materials in liquid effluents released to unrestricted areas should not exceed the concentration limits in Table 2, Column 2, and Note 4 of Appendix B to 10 CFR Part 20. 2. The LWMS should be designed with adequate capacity to process liquid wastes during periods when major processing equipment may be down for maintenance (single failures) and during periods of excessive waste generation. Systems that have adequate capacity to process the anticipated wastes and that are capable of operating within the design objectives during normal operation, including AOOs, are acceptable. To meet these processing demands, interconnections between subsystems, redundant equipment, mobile equipment, and reserve storage and treatment capacity will be considered. 3. The seismic design of structures housing LWMS components, the safety and quality group classifications of liquid radwaste treatment equipment, and provisions to prevent and collect spills from indoor and outdoor storage tanks should conform to the guidelines of RG 1.143 for liquids and liquid wastes produced during normal operation and AOOs. RG 1.143 provides guidance in assigning
