Title:
METHOD FOR DECONTAMINATING TRITIUM-RADIATION-POLLUTED WATER
Document Type and Number:
WIPO Patent Application WO/2021/064806
Kind Code:
A1
Abstract:
[Problem] To provide a decontamination method in which tritium radiation is attenuated or eliminated from radiation-polluted water. [Solution] In the present invention, the following are executed: a step for performing an addition treatment to add a prescribed amount of a pulverulent mineral such as a silicon dioxide mineral and a nanoscale carbon liquid to heated tritium-polluted water in an addition treatment tank; a step for pumping the addition-treated water from the addition treatment tank to a mineral solid replenishing tank using a water-pressure pump; a step for causing the addition-treated water to collide with a mineral solid and passing the addition-treated water through the mineral solid replenishing tank; a step for returning the passed water to the addition treatment tank using the water-pressure pump; and a circulation process step for repeating the aforementioned steps in a prescribed period of time.
