Abstract
Provided are a separation and recovery device for a liquid waste including a radionuclide, and a separation and recovery method using the same. Specifically, the present disclosure relates to a separation and recovery device that may effectively separate a liquid waste, such as a waste detergent including a radionuclide, and simultaneously, may prevent the release of tritium and radiocarbon to the outside, and a separation and recovery method using the same.
Claims13
A separation and recovery device for a liquid waste including a radionuclide, the separation and recovery device comprising:
- a liquid waste storage unit that stores 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 from 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 condensates the liquid waste evaporated by heating by 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, in which one end of the transfer tube is dipped in the condensate in the condensate recovery unit,
- wherein 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.
