A particularly simple NH4Cl-based method for the dissolution of UO2 and rare earth oxides in LiCl-KCl melt under air atmosphere

A particularly simple method utilizing NH4Cl for the dissolution of UO2 and rare earth oxides (RExOy) on the surface of LiCl-KCl melt is presented in this work. By this method, UO2 and RExOy can be successfully dissolved into the LiCl-KCl melt in air atmosphere with the formation of UO2Cl2 and RECl3.294
