A molten salt technology using Li 2 O-LiCl has been extensively investigated to recover uranium metal from spent fuels in the field of nuclear energy. In the reduction process, it is an important point to maintain the concentration of Li 2 O. ZrO 2 is inevitably contained in the spent fuels because Zr is one of the main components of fuel rod hulls. Therefore, the fate of ZrO 2 in Li 2 O-LiCl molten salt has been investigated. It was found that Li 2 ZrO 3 and Li 4 ZrO 4 were formed chemically
