Abstract

A milking process is described for preparing 239Np from 243Am. The process includes the stabilization of Np(IV) with ascorbic acid, isolation of Np(IV) by extraction with TOPO/dodecane and stripping of Np with (NH4)2CO3. The yield amounts to 60%. During milking, about 2% of the 243Am ends up in the scrub which is collected and reprocessed together with the remaining feed after 25 operations using extraction chromatography.
