The following comments are a response to 3 commenters on an anti-nuclear letter published in the Burlington Free Press: http://www.burlingtonfreepress.com/comments/article/20120418/OPINION03/120417038/Letter-Work-shut-down-Vermont-Yankee
Mssrs. Rogati, Carter and McDonald: With all due respect, you’re missing the forest for the trees here.
VY, like all nuclear plants, IS subject to possible accidents: indeed, it’s designed for them. That’s the so-called “design basis” of the plant. If a catastrophic “beyond design basis” accident were to occur, however improbable that may be, the results would devastate a significant area of New England. (Since you’re all hungry for details, here’s a 2006 report by Jan Beyea, prepared for the Attorney General of MA, estimating damage in the hundreds of billions of dollars:
2) Even if no eventuality ever exceeds the basis for which nuclear plants are designed, there is little margin for error in their operation either: small mistakes can have major consequences. Yet nuclear plants are run by human beings, who, even under the best of circumstances, make mistakes. Murphy’s law pertains as much to nuclear power as to other human endeavors. One need only look at the twice collapsed cooling towers at VY to see that its operators are not perfect. It is fortunate that the collapse of the cooling towers had no radiological consequence, but that’s good luck, not an indication of infallibility.
What unites VY and Fukushima — besides their substantially identical design — is not the PARTICULAR accidents most likely to occur, but rather their common vulnerability to loss of offsite power which, at Fukushima, led to loss of cooling water, and their inadequate containment design for which, it turns out, hard venting did NOT adequately compensate.
Peruse a list of major nuclear accidents and what leaps off the page is that almost every one of them had a different trigger: neither Chernobyl nor Three Mile Island were subjected to earthquakes or tsunamis, and yet they melted down. The only common cause is the one you folks are intentionally missing: all nuclear plants are designed, built, and run by fallible humans.
