hould be consistent with those given in RG 1.140. The building mixing efficiency for containment internal cleanup should be consistent with NUREG-0016, NUREG-0017, ANSI/ANS 18.1-1999, or the basis for different containment cleanup parameters should be documented. The review should evaluate the types and characteristics of filtration systems and adsorbent media proposed to treat gaseous process and effluent streams, including type of charcoal media (grade, mesh size, and bulk density); number and volume of charcoal decay tanks; dynamic adsorption coefficients for charcoal media and retention times; removal efficiencies for HEPA filtration systems, taking into account the expected physical, chemical, and radiological properties of gaseous process and effluent streams, and processing flow rates. 4. Decontamination factors applied to reduce liquid effluent releases to the environment should be consistent with those given in NUREG-0016, NUREG-0017, or ANSI/ANS 18.1-1999. The review should evaluate the types and characteristics of filtration systems, ion-exchange resins, and adsorbent media proposed to treat liquid process and effluent streams, including number and volume of ion-exchange resin column or activated charcoal bed; types and volumes of ion-exchange resins or activated charcoals; removal efficiencies and decontamination factors, taking into account the expected physical, chemical, processing flow rates, and radiological properties of liquid process and effluent streams. 5. The RWMS component design augmentations used in cost-benefit analysis should be consistent with the guidance of RG 1.110. The requirements to conduct a cost-benefit analysis and identify acceptable cost-benefit ratios in assessing the acceptability of such analyses are given in Section II.D of Appendix I to 10 CFR Part 50. Section II.D of Appendix I requires that the applicant demonstrate that the plant design includes all items of reasonably demonstrated technology which, when added to RMWS
