If you think about it the silence on how to handle Nuclear waste is actual extremely telling. other nations process it down (for those unfamiliar with the process you can keep using the fuel until you get hydrogen, or water. Though it becomes impractical eventually. US Plants only use it once. Now the funny thing about that is that the by product is extremely close to what you'd use to build a Nuclear missle, this is why we don't like bozos like North Korea having Nuclear power plants. Anyway I wouldn't worry about spent fuel in landfills but depending on your politics I mght worry about it being lobbed at the Chinese.
