Keeping radioactive waste far away from anyone who might be harmed by it, even for thousands of years, is a solved problem. We know how to bury stuff deep underground in a geologically stable region. Or if you prefer, throw it in a subduction zone.
As with most things nuclear-related, the real problem is NIMBY. If a country as large and sparsely populated as the U.S. can't agree on a place to bury nuclear waste, there doesn't seem to be much hope for others like France and Japan.
