Why I am not worried about Japan’s nuclear reactors

That’s the title of a post on the Morgsatlarge, reprinting a letter from Dr. Josef Oehman of MIT. According to his web page, his main research interest is “risk management in the value chain, with a special focus on lean product development.” Although he’s a business professor and not a nuclear scientist, his father worked in the German nuclear power industry, and the post provides a detailed and persuasive (at least to me) explanation of how the endangered Japanese nuclear power plants work, and why their multiple backup systems  ensure that there will be neither a nuclear explosion nor a catastophic release of radiation. The American cable TV channels, by the way, seem to be taking a much more sober approach than they did yesterday, when Wolf Blitzer was irresponsibly raising fear of “another Chernobyl.”

A shorter article by William Tucker in Monday’s Wall Street Journal covers some of the same ground.
