“Greenpeace has always fought - and will continue to fight - vigorously against nuclear power because it is an unacceptable risk to the environment and to humanity. The only solution is to halt the expansion of all nuclear power, and for the shutdown of existing plants.”http://www.greenpeace.org/internatio...paigns/nuclear Patrick Moore, one of the founders of Greenpeace, had this to say, “In the early 1970s when I helped found Greenpeace, I believed that nuclear energy was synonymous with nuclear holocaust, as did most of my compatriots. That's the conviction that inspired Greenpeace's first voyage up the spectacular rocky northwest coast to protest the testing of U.S. hydrogen bombs in Alaska's Aleutian Islands. Thirty years on, my views have changed, and the rest of the environmental movement needs to update its views, too, because nuclear energy may just be the energy source that can save our planet from another possible disaster: catastrophic climate change.”http://www.washingtonpost.com/wp-dyn...06/04/14/AR200... Wind power and solar generation can’t hack it. *So what are the alternatives to nuclear/hydrocarbon power plants? * * * * Brownouts and blackouts on a regular basis * * * * The surest way to a low standard of living is energy poverty Let us examine the waste balance sheet of a coal-fired vs. a nuclear power plant. A 1,000 Megawatt coal-fired power plant produces solid wastes at a rate of 1,800 pounds per minute that includes * * * * * * * * 19 toxic metals such as arsenic * * * * * * * * carcinogens such as benzopyrene * * * * 30 pounds of sulfur dioxide per second * * * * As much nitrous oxide as 200,000 automobiles * * * * 50 times the radioactive emissions of an average nuclear power plant * * * * * * * * Each (short) ton of coal contains * * * * * * * * * * * * 50 grams of Uranium * * * * * * * * * * * * 129 grams of Thorium According to NCRP Reports No. 92 and No. 95, population exposure from the operation of 1000-MWe nuclear and coal-fired power plants amounts to 490 person-rem/year for coal plants and 4.8 person-rem/year for nuclear plants. Thus, the population effective dose equivalent from coal plants is 100 times that from nuclear plants. Highly radioactive daughter particles amount to 3% (by volume) or about .2 cubic meters from a year’s production from a 1,000 Megawatt Light Water Reactor (LWR) power plant. In that 3% you have the following significant radionuclides with their half lives. Gases * Kypton-85 * * * * * * 10.7 years * Xenon-133 * * * * * * *5.3 days Solids * Strontium-90 * * * * 28.1 years * Molybdenum-99 * *66.7 hours * Iodine-131 * * * * * * *8.1 days * Cesium-137 * * * * *30.2 years * Cerium-144 * * * * 285.0 days After 30 half lives a radioactive material is deemed safe. *Picking the longest lived, Cesium-137 at 30.2 years, 30x30.2=906 years. We are not talking about Yucca Mountain here; that is for wastes from nuclear weapons production. What about the remaining 97%? They can be immediately reused as nuclear fuel. *We recycle paper and not nuclear fuel? In 1977, that gem of a president Jimmy Carter canceled the Barnwell, South Carolina, reprocessing plant then nearing completion because of an exaggerated danger of terrorists stealing our nuclear fuel and chemically separating the plutonium from the uranium in order to build nuclear weapons with it. *They should live so long trying. France, Germany, Japan, and Russia continued with their reprocessing facilities and have assured themselves sources of readily available nuclear fuel for the foreseeable future. I am sure that the terrorist would never consider stealing from them.~ [Footnote .~ is the emoticon for irony] My point? *Start building nuclear reactors as fast as you can. --Mike Jr -------------------- why is no one talking about fusion ???!!!
