Reprocessing has been mostly blocked by the US due to proliferation concerns, but it reduces the problem enormously, since you then have new fuel plus some very nasty waste that decays on more human-friendly timescales. For reference, the amount of the very nasty waste produced by a lifetime's electricity demand for an average European citizen (so you probably want to multiply by 2 or 3 for future usage), immobilised in glass, is about the size of a hockey puck. A very deadly hockey puck mind, a kill-you-from-twenty-paces hockey puck, but a solid hockey puck. You know what we haven't figured out? How to even re-concentrate the several tonnes of dispersed waste product fossil fuels put into the atmosphere for the same number of kWh, not as an accident but as part of normal operations, and that's currently wreaking havoc everywhere.
