Molten salt electrolytic purification apparatus and molten salt electrolytic purification method

摘要

PPROBLEM TO BE SOLVED: To efficiently recover a large amount of U and TRU without increasing an amount of liquid metal used as an anode by steadily maintaining the interface of a liquid metal electrode of a molten salt electrolytic refiner to an original composition. PSOLUTION: The molten salt electrolytic refiner having an electrolytic cell installed in an electric furnace and housed with a molten salt, an anode container charged with a used nuclear fuel, and a liquid metal crucible housed with liquid metal cathode is equipped with a compressive apparatus which compresses the solid precipitated object generated at the interface of the liquid metal cathode to a liquid metal cathode bottom.
