But I don't understand this:
"Within 40 years, used fuel has less than one-thousandth of the radioactivity it had when it was removed from the reactor."
If the half-life of Uranium (or whatever fuel is used) is thousands of years how the hell can the radiation of the waste products decrease to less than one-thousandth in 40 years?
Also, the article doesn't say how "easy" it is to mine nuclear fuel and how much energy it costs. It would be interesting to know how much of a reserve there is.
