The anodic dissolution of U and Zr metal was studied in LiCl-KCl-UCl3 and LiCl-KCl-ZrCl4, respectively, at 773K by using cyclic voltammetry. The anodic dissolution of U-Zr alloy in LiCl-KCl-UCl3 was also studied at 773K. The transfer coefficients evaluated using Tafel analysis and the method of Allen-Hickling for U and Zr dissolution were found to be in fair agreement with one other. The U dissolution in LiCl-KCl-UCl3 and the Zr dissolution in LiCl-KCl-ZrCl4 were also studied using chronoamperometry, and the diffusion coefficient of U3+ was found to be in the range of 2.9 x 10-5 to 3.3 x 10-5cm2/s; in agreement with literature data.
