sure it does (reflect poorly on nukes in general). It means we now understand there is no possibility that they can be safely built. Unless you're okay with gradually radiating the entire planet or at least rendering little pieces of it permanently uninhabitable with each natural disaster. Chernobyl = 5% of Europe's farmland lost forever. Fukushima = 50% of the world's tuna spawning grounds permanently irradiated. I like to eat, how about you? How many more of these will you tolerate so your HD TV can have "instant on" capabiilty?
