SEPARATION AND RECOVERY DEVICE FOR LIQUID WASTE INCLUDING RADIONUCLIDE, AND SEPARATION AND RECOVERY METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a separation and recovery device for a liquid waste including a radionuclide, and a separation and recovery method using the same.SOLUTION: The separation and recovery device for a liquid waste including a radionuclide includes: a liquid waste storage unit that stores therein a liquid waste mixture including a radionuclide; a heating unit that heats the liquid waste storage unit to evaporate a low-boiling point liquid waste including a radionuclide in the liquid waste mixture in the liquid waste storage unit; a condensation chamber that is connected to an upper portion of the heating unit and is capable of condensing the liquid waste evaporated by heating with the heating unit; a condensate recovery unit that is connected to the condensation chamber and recovers a condensate condensed in the condensation chamber; and a transfer tube that transfers the condensate condensed in the condensation chamber to the condensate recovery unit and has one end immersed in the condensate in the condensate recovery unit. The evaporated low-boiling point liquid waste moves from the heating unit to the condensate recovery unit by a pressure difference between the heating unit and the condensate recovery unit, and the radionuclide evaporated by the heating unit is recovered by being dissolved in the condensate that is recovered in the condensate recovery unit.
