Abstract

Tc play an important role in U/Pu partition when U(IV) is used as reducing agent in PUREX process. In this work, U/Pu partition flowsheet experiments were studied using different organic reducing agents, which included N,N-dimethylhydroxylamine (DMHAN)–methylhydrazine (MMH), acetohydroxamic acid (AHA) and dihydroxyurea (DHU). The results showed very good U/Pu partition performance in the presence of Tc, which mean Tc would not cause major malfunctions in the U/Pu partition operation with these reducing agents. The technetium fractions distributed in the products was mainly attributed to Tc(VII) reduction kinetics with different reducing agents.
