Should the events in Japan cause the United States to change its policies on nuclear energy? The outcome there is far from certain, but critics of nuclear power have been vocal, and some countries, notably Germany, have talked about scaling back considerably. The headlines and moon-suit pictures have been scary enough. Perhaps too scary? While there is nothing good about a nuclear plant accident, even one on the scale of Chernobyl had consequences that were far from catastrophic. Supporters say Japan's problems had more to do with old designs and bad planning than the fury of nature. The issue arises just as we were coming to a rough national consensus to ramp up this dormant clean energy source. Time to pull back? I'd like to hear your thoughts in the comments section below.
