I understand it is cheaper to use fresh uranium rather than reprocess. That may not be the case by the end of this century. Alternatives to reprocessing include thorium and higher burnup reactors that get more out of fresh uranium.

From what I can see the Swedish used fuel repository doesn't allow for retrieval of buried material. I think Australia should store used fuel (commercial reactors and subs) in a disused outback mine in the Woomera Prohibited Area and worry about reprocessing later. Uranium came out of a hole in the ground; it and its alteration products can go back there.
