Net energy from nuclear power

摘要: An analysis of net energy from nuclear power plants is dependent on a large number variables and assumptions. The requirements as they relate to reactor type, concentration uranium in the ore, enrichment tails assays, possible recycle plutonium were examined. Specifically, four types considered: pressurized water reactor, boiling high temperature gas-cooled heavy (CANDU). systems employing both conventional (current) ores with 0.176 percent Chattanooga Shales 0.006 determined. Data given for no recycle, only, plus recycle. Starting mining process continuing through fuel reprocessing waste storage, an evaluation electrical thermal each was made. All energy, direct indirect, required by processing order produce obtained adding quantities individual processes. inputs operation system assumed life approximately 30 years are tabulated nine example cases. input weremore » based production 197,100,000 MWH(e), i.e., 1000 MW(e) plant average factor 0.75. Both tabulated, it should be emphasized that needed. It found electricity generated far exceeded all cases considered. (auth)« less
