Content:
f model 1,000 MWe LWR with once-through cooling. Fossil fuel: Electrical energy (thousands of MW-hour) 323 <5 percent of model 1,000 MWe LWR output. Equivalent coal (thousands of MT) 118 Equivalent to the consumption of a 45 MWe coal-fired power plant. Natural gas (millions of scf) 135 <0.4 percent of model 1,000 MWe energy output. Effluents—Chemical (MT) Gases (including entrainment): 3 SO X 4,400 NO X 4 1,190 Equivalent to emissions from 45 MWe coal-fired plant for a year. Hydrocarbons 14 CO 29.6 Particulates 1,154 Other gases: F .67 Principally from UF 6 production, enrichment, and reprocessing. Concentration within range of state standards—below level that has effects on human health. HCl .014 Liquids: SO − 4 NO − 3 Fluoride Ca + C1 − Na + NH 3 Fe 9.9 25.8 12.9 5.4 8.5 12.1 10.0 .4 From enrichment, fuel fabrication, and reprocessing steps. Components that constitute a potential for adverse environmental effect are present in dilute concentrations and receive additional dilution by receiving bodies of water to levels below permissible standards. The constituents that require dilution and the flow of dilution water are: NH 3 —600 cfs., NO 3 —20 cfs., Fluoride—70 cfs. Tailings solutions (thousands of MT) 240 From mills only—no significant effluents to environment. Solids 91,000 Principally from mills—no significant effluents to environment. Effluents—Radiological (curies) Gases (including entrainment): Rn-222 Presently under reconsideration by the Commission. Ra-226 .02 Th-230 .02 Uranium .034 Tritium (thousands) 18.1 C-14 24 Kr-85 (thousands) 400 Ru-106 .14 Principally from fuel reprocessing plants. I-129 1.3 I-131 .83 Tc-99 Presently under consideration by the Commission. Fission products and transuranics .203 Liquids: Uranium and daughters 2.1 Principally from milling—included tailings liquor and returned to ground—no effluents; therefore, no effect on environment. Ra-226 .0034 From UF 6 production. Th-230 .0015 Th-234 .01 From fuel
