... use it as fuel? If we had a modular MSR reactor we could cart it there and "burn" it. Otherwise can't you just de-enrich it by mixing in other Uranium isotopes and send it the usual way to the nuclear solid fuel rod monopoly? Is what they actually mean is "it's REALLY valuable since it's already enriched weapons-grade, so how do we keep it until someone "safe" pays for it."?
