But we don't have that solution yet (see above). That's like hanging on the idea of having nuclear fusion available. Yes, theoretically nice, but until they are practical, we shouldn't count on it.
Yes, theoretically the "waste" of current reactors still has energy to be harvested. But practically we can't use them to a degree where there is no waste afterwards.
For the past decades and sitll ongoing, fission reactors are not clean (also decomissioning them leaves a lot of unusable waste; and they have to be decomissioned at some point).
Also from what I know, extracting the nuclear material from the earth and preparing it for use in a fission reactor is not very environmentally friendly either.
Is nuclear better than coal? Very likely. But it's not clean.
Reprocessing already exists and it's been done for decades. I can't imagine reprocessing fuel for recycling the usable components is that compelling in the US and it would be more geared to waste reduction. 99% of spent fuel by mass could be reused or otherwise treated differently for disposal as it's radioactivity is much much smaller than the portion that has been transmuted during power production.
