Beschreibungen/Notizen

• In order to establish a new technique to separate americium from curium and lanthanides in the treatment process of High Active Waste, the feasibility of the separation of Am by reduction to divalent state in chloride melts was studied. As a homologue of the formation of divalent Am and its reaction, electrochemical measurements and electrolysis of Nd were conducted using the LiCl-KCl eutectic melt. Based on the reported formal potentials and the thermodynamic values of the compound of related elements, the feasibility of the Am separation was evaluated. As a result, a rough concept of the new process to be attached to the downstream of the aqueous reprocessing process was proposed.
