Nuclear Power to Preserve the Environment and to Meet Essential Human Needs Richard J. McDonald RJM5@sbcglobal.net November 23, 2014 The position and goal of EFN-USA is to show how nuclear power can directly or indirectly address environmental problems while providing energy to maintain developed countries and energy to advance developing countries. Depletion of conventional oil, lack of sufficient potable water, and famine drive conflicts among nations, and war is the greatest environmental threat of them all. Nuclear power produces large amounts of energy at high (~50) Energy Return on Energy Invested (EROI) compared to solar photovoltaic (~2) and wind (~4). This means you have energy to do other things besides producing more energy, not only to maintain the U.S., Europe, and Japan; but to develop Africa, Asia, and South America. Using nuclear power as our main source of energy reduces pollution, slows resource depletion, lessens the likelihood of war, and preserves environment while providing essential human needs. Electricity: Nuclear power presently supplies 11% of electricity worldwide. It supplies 75% in France making that nation a low carbon emitter. No source is without a CO2 footprint, but that for nuclear is lower than any other energy source with the exception of hydroelectric. The CO2 footprint shrinks further when you reprocess the spent fuel (as presently done by France). Nuclear electricity can replace all coal burning and give the greatest reduction in CO2 production per unit energy produced. “Renewables� have larger carbon emissions because they take a lot of energy to produce (often from burning coal) and return little in excess. (Low EROI) Liquid Fuels: Liquid fuels are vital to building and maintaining infrastructure in the developed world and even more vital to the developing world because they can power heavy machinery in remote areas. Making synthetic fuels from the energy of a nuclear reactor and the Fischer-Tropsch (F-T) process yields a carbonneutral fuel because the products of combustion are the same as the feed stock (CO2 and water). Potable Water: Producing potable water from sea water gives a product free from agricultural and chemical contamination. By providing plentiful water to large coastal cities, lake and river water and aquifers can revert to more natural states to support other species.
