> Part of the appeal of building new reactors is that they are so much more efficient that they can actually burn up more of the spent fuel than they themselves create. This is an outright lie with regard to Gen III+ reactors. MOX is filthy. It's just turning almost-inert U238 and relatively low activity Pu239 into Pu240, Pu241 and Cs-137. This is after a reprocessing step that vastly increases the volumne of contaminated material and leaks a bunch of it into the environment. The volume of inert material in the spent fuel is a red herring.
