es to the method of calculating releases of radioactive materials in liquid and gaseous effluents from nuclear power plants. 3. RG 1.140, “Design, Inspection, and Testing Criteria for Air Filtration and Adsorption Units of Normal Atmosphere Cleanup Systems in Light-Water-Cooled Nuclear Power Plants,” as it relates to the design, testing, and maintenance of normal ventilation exhaust system air filtration and adsorption units at nuclear power plants. 4. DC/COL-ISG-5, Interim Staff Guidance on NUREG-0800, SRP Section 11.1. Specific SRP acceptance criteria are as follows: 1. All normal operation and AOO sources of radioactive liquid and gaseous effluents delineated above in Subsection I will be considered. 2. For each source of liquid and gaseous waste considered above in Subsection I.1 (as described in SRP Sections 11.2, 11.3, and 11.3 for RWMS), the volumes, concentrations, or release rates of radioactive materials given for normal operation and AOOs should be developed using methods that are consistent with those given in NUREG-0016, NUREG-0017, or ANSI/ANS 18.1-1999. 3. Decontamination factors used to reduce gaseous effluent releases to the environment, such as noble gases from decay tanks, iodine removal systems, and high-efficiency particulate air (HEPA) filters for building ventilation exhaust systems and containment internal cleanup systems should 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 11.1-9 Draft Revision 4 –August 2014 size, and bulk density); number and volume of charcoal decay tanks; dynamic adsorption coefficients for charcoal media and
