Title:
METHOD FOR TREATING CHEMICAL DECONTAMINATION PROCESS WASTE OF NUCLEAR FACILITY BY USING OXIDATION-REDUCTION AND PRECIPITATION REACTIONS
Document Type and Number:
WIPO Patent Application WO/2019/045205
Kind Code:
A1
Abstract:
The present invention relates to a method for treating the chemical decontamination process waste of a nuclear facility by using oxidation-reduction and precipitation reactions, the method: being readily applicable to a primary cooling system-based chemical decontamination process of a nuclear facility, particularly, a pressurized water reactor nuclear power plant; using oxidation-reduction and precipitation reactions so as to precipitate the metal oxide of process waste into a precipitate and remove the same, thereby minimizing the generation of waste; and enabling the acceptance of waste disposal to increase.
