| titleOfInvention | Chemical decontamination method for radioactive contaminants |
| abstract | (57) [Abstract] [PROBLEMS] To efficiently decontaminate metal structures and parts of radioactively contaminated nuclear reactors, simplify the radioactive decontamination process and reduce the amount of secondary waste generated. Decrease. In a method for chemically removing radioactive contaminants, a dicarboxylic acid is used for reductive dissolution of an oxide incorporating radioactivity, a permanganate is used for oxidative dissolution, and reduction and oxidation are repeated. Perform at a liquid temperature of 100 ° C or less. That is, first perform an oxidation treatment with a permanganate solution, and then treat the permanganate by adding dicarboxylic acid, Chemically decontaminate nuclear reactor metal structures and components contaminated by radioactivity with excess dicarboxylic acid. By adding the dicarboxylic acid directly to the permanganate solution, the conventional purification steps and removal and disposal steps of the permanganate solution can be omitted. |
