... It can separate many or even all actinides at once and produce highly radioactive fuel which is harder to manipulate for theft or making nuclear weapons ... was designed to separate plutonium only for weapons, and it also leaves the minor actinides (americium and curium) behind, producing waste with more long-lived. 102 to 105 years after the use of the nuclear fuel is produced by the actinides, since there are no fission products with half-lives in this range ...
