Title:
DECONTAMINATION SYSTEM AND DECONTAMINATION METHOD USING GAS HYDRATE
Document Type and Number:
WIPO Patent Application WO/2024/025067
Kind Code:
A1
Abstract:
The present invention relates to a decontamination system and a decontamination method using gas hydrate that can be applied to an ultra-mega ship to store and decontaminate large quantities of radioactive water, the system comprising: a contaminated water supply module supplying contaminated water filled in a first cargo tank and containing hypersaline and high-concentration radioactive materials; a gas hydrate forming module that forms gas hydrate by injecting gas into the contaminated water supplied from the contaminated water supply module; a solid-liquid separation module that forms the gas hydrate formed by means of the gas hydrate forming module into a pellet shape and separates same from radioactive materials; a washing module that washes the pellets; a dissociation module that separates water molecules and gas from the pellets washed by the washing module; and a radioactive material storage module that stores the radioactive materials separated in the solid-liquid separation module. This configuration can dramatically reduce the cost and time of manufacturing a decontamination plant.
