And, while I try to hide my embarrassment---while Transatomic is BS, the concept of nuclear fuel cycles using waste is not, and many IV Generation designs are specifically working toward that. My main point was we likely won't need to wait millennia, or even centuries, for a lot of that waste to become useful.
Bah, my bad. I was just looking for a quick citation for nuclear fuel cycles, saw "MIT Tech Review" (usually a very good source), and grabbed it. Thanks for catching it.
