effluents can be found in Section 6.2.2.9 of NUREG-1437. E. Radioactive Effluents Radioactive effluents estimated to be released to the environment from reprocessing and waste manage- ment activities and certain other phases of the fuel cycle process are set forth in Table S-3. Using these data, the staff has calculated for 1 year of operation of the model 1000-MW(e) LWR, the 100-year involuntary environmental dose commitment to the U.S. population from the LWR-supporting fuel cycle. These calculations estimate that the overall involuntary total body gaseous dose commitment to the U.S. population from the fuel cycle (excluding reactor releases and the dose commitment due to radon-222) would be approximately 4 person-sievert (400 man-rem) per year of operation of the model 1000 MW(e) LWR (reference reactor year [RRY]). Based on Table S-3 values, the additional involuntary total body dose commitment to the U.S. population from radioactive liquid effluents due to all fuel cycle operations other than reactor operation would be approximately 2 person-sievert (200 man-rem) per year of opera- tion. Thus, the estimated involuntary 100-year environmental dose commitment to the U.S. population from radioactive gaseous and liquid releases due to these portions of the fuel cycle is approximately 6 person-sievert (600 man-rem) (whole body) per RRY. Using risk estimators of 500 cancer deaths per 10,000 person-sievert (1 million man-rem) (NUREG/CR-4214, Rev. 2, Part I) (Evans et al. 1993), the estimated cancer risk would be 0.3 per RRY (6 × 500 × 10-4). At this time, Table S-3 does not address the radiological impacts associated with radon-222 releases and technetium-99 releases. NUREG-1437, Section 6.2.2.1, provides an analysis of the environmental impacts from these two radionuclides as they pertain to the uranium fuel cycle, including a detailed discussion of predicted health effects and the technical basis for the health effects.
