The price of a melt-down or terror attack at an American nuke is beyond calculation. In most cases, reactors built in areas once far from population centers have now been surrounded by development, some of it bumping right up to the plant perimeters. Had the jets that hit the World Trade Center on 9/11/2001 instead hit Indian Point Units Two and Three, 45 miles north, the human and financial costs would have been unimaginable. Imagine the entire metropolitan New York area being made permanently uninhabitable, and then calculate out what happens to the US economy.
http://www.smirkingchimp.com/thread/7129There remains no way to protect any of the roughly 450 commercial reactors on this planet from either terror attack or an error on the part of plant operators.
Those advocating more nukes ignore the myriad good reasons why no private insurance company has stepped forward to insure them against catastrophe. Those who say future accidents are impossible forget that exactly the same was said of TMI and Chernobyl.
The commercial fuel cycle DOES emit global warming in the uranium enrichment process. Uranium mining kills miners. Milling leaves billions of tons of tailings that emit immeasurable quantities of radioactive radon. Regular reactor operations spew direct heat in to the air and water. They also pump fallout into the increasingly populated surroundings, with impacts on the infant death rate that have already been measured and proven. And, of course, there is no solution for the management of high-level waste, a problem the industry promised would be solved a half-century ago.
Economically, early forays into a "new generation" of reactors have already been plagued by huge cost overruns and construction delays. At best they would take ten to fifteen years to build, by which time renewable sources and efficiency---which are already cheaper than new nukes---will have totally outstripped this failed technology. Small wonder Wall Street wants no part of this radioactive hype, which is essentially just another corporate campaign for taxpayer handouts.
This past Earth Day was an orgy of corporate greenwashing, aided by the always-compliant major media, tried to portray nukes as "green" energy. Nothing could be further from the truth.
