Potential radiological impact of a conceptual Hanford Nuclear Energy Center

Conference ·
OSTI ID:5539036
The potential radiological impact of the siting of 20 light-water reactors and associated nuclear fuel cycle facilities on the Hanford reservation was evaluated by calculating the potential radiation doses received by individuals and populations in the vicinity of the reservation. The largest contributor to the potential radiation doses, to both the individual and the 50-mile population, were the effluents from the conceptual 1500 MT/yr fuel reprocessing plant. The effluents from the 20 reactors combined was the second largest contributor. The radiation dose contributions from the 300 MT/yr mixed oxide fuel fabrication plant were insignificant. The highest organ dose from all facilities combined was 24 mrem/yr to the child thyroid; followed by 8 mrem/yr to the adult thyroid. The 50-year collective dose commitment to the population within 50 miles was about 50 man-rem for most organs of reference, while the estimate for bone was 70 man-rem. With the exception of /sup 85/Kr, the release rates of radionuclides were within the EPA guidelines. Removal of about 90% of the 4 x 10/sup 5/ Ci/yr per gigawatt-year of electricity of /sup 85/Kr from the fuel reprocessing plant gaseous effluents would be required for compliance with the EPA guidelines.
