Most of the Uranium and Tranceuranium(TRU) elements are recovered by spent-fuels-pyroprocess which is using electrorefining
and electrowinning. The components of occured molten salt waste mainly consist of Actinide(Ac) elements and Lanthanide(Ln)
elements. To lower radio-activity levels of the waste by excluding uranium and TRU elements, physicochemical behavior on
Ac and Ln elements is required a priori. In this study, we conducted electrochemical measurements with LaCl3 solution in
LiCl-KCl. For collection of the physicochemical data, cyclic-voltammetry and chronopotentiometry methods were used. We
compared those diffusion coefficient values.
