ect to determination of doses to the public ` NUREG-0543, Methods for Demonstrating LWR Compliance with the EPA Uranium Fuel Cycle Standard (NRC 1980), with respect to determination of compliance with 10 CFR 20.1301(d). Technical Rationale The technical rationale for evaluating the applicant’s estimation of radiation doses to members of the public is discussed in the following paragraph: All light-water-cooled reactors release small quantities of radioactive materials to the environment. The criteria for doses from liquid effluents and air dose from gaseous effluents for any individual in an unrestricted area from all pathways of exposure are designed to provide a means of ensuring that effluent releases from light-water-cooled reactors are below levels that could have a negative impact. The doses to individuals from radioactive gaseous and liquid releases and the doses to the population within 80 km (50 mi) of the plant are assessed before plant operations to ensure that the plant design is so that effluent releases meet the 10 CFR 50, Appendix I, criteria. III. REVIEW PROCEDURES The reviewer’s analysis of doses is usually an iterative process in coordination with the reviewer for ESRP 3.5 and adheres to the following general steps: (1) Calculate the dose to the maximally exposed individual and collective dose estimates. NUREG-1555 5.4.2-4 October 1999 ` Forward these estimates to the reviewer for ESRP 3.5 for comparison with the design objectives and to evaluate the radwaste cost estimate described in 10 CFR 50, Appendix I. If the reviewer for ESRP 3.5 determines that the doses do not meet these design objectives, additional analysis may be needed, and on this basis, source terms may be revised by the ESRP 3.5 reviewer. ` If the source terms are revised, use them to calculate another set of individual maximum doses and collective population doses and forward it to the reviewer for ESRP 3.5 for evaluation. ` Repeat this procedure until the reviewer for ESRP 3.5
