Nuclear power plants are very very clean - ever been to one? Nuclear waste is actually fuel that can be burned in a breeder reactor, or elements that have value up to tens of thousands of dollars an ounce. In fact, we could actually replace our energy needs with safe clean Nuclear power. It is the safest industry ever created by humans. The "waste" is easier to deal with than any other type of fuel.
