re processed further or released to the environment. The holdup times are used in the source term calculations based on the methods described in RG 1.112 and NUREG-0016 (BWRs) or NUREG-0017 (PWRs) and ANSI/ANS 18.1-1999, as modified to reflect specific design features. 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 delay tanks, dynamic adsorption coefficients for charcoal media, and retention times, removal efficiencies and decontamination factors, taking into account the expected physical, chemical, and radiological properties of gaseous process and effluent streams, and processing flow rates. The review should determine whether performance meets or exceeds that noted in RG 1.52 and 1.140, and the method discussed in NUREG-0016 or NUREG-0017 (as modified). The above information may be drawn from standard DCs, industry standards, and/or topical reports and industry data for new or alternate gaseous waste treatment methods. Meeting the requirements of GDC 60 provides assurance that releases of radioactive materials in gaseous effluents to unrestricted areas during normal operation of the plant and AOOs will not result in offsite radiation doses exceeding the design objectives specified in Appendix I to 10 CFR Part 50 and concentrations of radioactive materials in gaseous effluents in any unrestricted area exceeding the limits specified in Table 2, Column 1, and Note 4 of Appendix B to 10 CFR Part 20. The control of radioactive gases and vapors, generated as byproducts of the operation of the liquid waste management system (LWMS) and solid waste management system (SWMS) is addressed here through the design considerations of exhaust ventilation and treatment systems using the guidance in the guidance of SRP Sections 9.4, 11.2, 11.4, and 11.5, RG 1.52, 1.140 and
