Abstract

The electrochemical nucleation of uranium in molten salts on vitreous carbon was studied using chronoamperometry. It is shown that, whatever the applied overpotential and the temperature of the melt, the nucleation of uranium is instantaneous, three-dimensional and controlled by hemispherical diffusion. The diffusion coefficient of UIII is calculated. The value obtained by chronoamperometry is in good agreement with that obtained by cyclic voltammetry in previous studies [1].
