99% of the waste is eliminated by reprocessing it via breeder reactors. What's left has a half life in the hundreds of years instead of billions. Reprocessing also increases the extractable energy density of uranium 100 fold, meaning that with only known uranium reserves, humanity could meet 100% of its current energy needs from fission for 38,000 years.
