REVIEW RESPONSIBILITIES Primary - Organization responsible for review of source term associated with normal operations. Secondary - None. I. AREAS OF REVIEW At the early site permit (ESP), construction permit (CP) or standard design certification stage of review, the staff reviews the information in the applicant’s safety analysis report (SAR) on the sources of radioactivity that are input to the radioactive waste management systems for treatment of liquid and gaseous wastes. At the operating license (OL) or combined license (COL) stage of review, the staff confirms the information accepted at the CP or standard design certification stage. 1. The staff’s review of the radioactive source terms includes consideration of parameters used to determine the concentration of each isotope in the reactor coolant; fraction of fission product activity released to the reactor coolant; and concentrations of all nonfission product radioactive isotopes in the reactor coolant. The following sources are considered in the evaluation of effluent releases: 11.1-2 Revision 3 - March 2007 A. Boiling water reactor (BWR) gaseous wastes (noble gases, radio iodine, particulates, carbon-14 and tritium), consisting of offgases from the main condenser evacuation and turbine gland sealing systems, steam and liquid leakage to containment, radwaste, turbine, fuel handling and auxiliary buildings, and ventilation system exhausts from buildings having the potential for containing radioactive materials. B. BWR liquid wastes, consisting of leakage of equipment and floor drains from buildings housing equipment and components that may contain radioactive fluids; contaminated liquids produced by plant operations, such as demineralizer regenerants and resin sluice water, filter backwashes, ultrasonic resin cleaning rinses, decontamination solutions, and laboratory samples and rinses; and detergent wastes. C. Pressurized water reactor (PWR) gaseous wastes (noble gases, radio iodine, particulates,
