Abstract
The spent nuclear fuel reprocessing method includes contacting an organic phase containing Np(VI) with a hydrophilic substituted hydroxylamine in which at least one N—H hydrogen of the hydroxylamine is replaced by an organic substituent, there being at least one such organic substituent having one or more hydroxyl groups. Np(VI) is reduced to Np(V), which is then backwashed into an aqueous phase.
