The recycling process that France currently uses recovers about 96% of the radioactive material remaining in nuclear waste and produces new fuel rods usable in conventional reactors. Spent fuel rods from conventional reactors can also be used in other types of reactors. For whatever reason, we in the US just shove all of our nuclear waste in old mines like it’s still 1950 but technology has continued to develop and places that are more invested in nuclear energy have much better ways of dealing with the waste.
