A study was made of the electrochemical properties of PuCl3 in molten LiCl-KCl eutectic at 733 to 833K. Cyclic voltammetry and chronopotentiometry, on inert metallic tungsten and molybdenum electrodes, were used to investigate the reduction mechanism and transport parameters. The results showed that Pu3+ was reduced to Pu metal via a single-step mechanism, and that the diffusion coefficient of Pu3+ ions was 1.6 x 10-5cm2/s at 733K.
