more expensive than other kinds of clean-ups, like coal clean ups for instance, because first of all nuclear clean ups are technically possible, where as the alternate clean-ups are not, not for any imaginable amount of money. Therefore people simply don't do the clean ups associated with other technology. They therefore don't cost any money and are free, except (of course) for the millions of people and thousand of square kilometers destroyed.
Further, the standards to which nuclear clean-ups are held are positively absurd, mostly because people on this planet hold a completely ignorant and absurd view of how dangerous radiation actually is.
This absurdity is trenchantly and clearly explained in the following link from the brilliant health physicist Bernard L. Cohen.
http://www.ecolo.org/documents/documents_in_english/en.cost_of_lives_saved.docThe problem lies not with the inherent danger of nuclear energy, but with the fact that people have somehow concluded that a person potentially injured by nuclear means is somehow worth several millions of persons injured by other means. This is a cultural decision, not an economic or technical one.
In short, the issue is once again, stupidity and myopia.
I have to run. There are a lot of cases of stupidity and myopia cropping up today that I need to address.
Great news on the new nuclear plant in Idaho though. I hope it's built.
