摘要
PURPOSE: A method and an apparatus for concentrating Cs and Sr existed in the LiCl-KCl eutectic molten salt are provided to separates the salt waste containing the radionuclide of the low concentration and recycles. CONSTITUTION: A container upper portion in which the radioactive salt waste exists is controlled by the temperature of two-phase region in which the solid and liquid coexist. A container lower part is controlled by the temperature of the liquid area of the salt waste(s10). The liquefied salt waste is solidified to a top-down manner by perpendicularly transferring the instrument in which the salt waste is stored(s20). The salt waste in which a radionuclide is segregated into the high concentration in the container lower region is solidified and is removed after dividing(s30). The salt waste remained after separating and removing is reused in the pyro processing process(s40).
