Yeah. I am no expert by any means. I was thinking of something more along the lines of an integral fast reactor were the heavy elements are removed and reused in the reactor leaving the waste "purified" of those heavy elements. So the really dangerous stuff never leaves the building and is used up to produce energy. This means instead of having waste that is dangerous for tens of thousands of years you only have to worry about it for a few hundred. But I guess the some of the output from a IFT then could be used in something like a CANDU reactor? So you could use the combination of the two to use up most of the fissionable material and until the waste is so depleted that it is useless and is turned into ceramics or glass and safely stored. Something like that. Regardless this means that nuclear reactors provide the closest we can possibly get to truly renewable energy source and provide a path forward away from fossil fuels that could meet the energy budget of the planet for the next hundred thousand years or so. Anybody who really cares even a little bit about the environment and global warming should be clamoring loudly for this sort of tech. Large scale nuclear power production combined with locally produce small scale (I mean distributed) solar makes a lot of sense, IMO.
