| titleOfInvention | Decontamination method of radioactive waste |
| abstract | (57) [Summary] [PROBLEMS] To reduce the time required for decontamination and to simplify the device configuration. SOLUTION: Heavy water (including tritium water) adhering to the inner surface of a pipe 1 contaminated with tritium is removed by evaporation by dry air heated by a heater 3 supplied into the pipe 1 from a pipe 10. Is done. Since it is cooled by the condenser 4, The heavy water and tritium water vapor contained in the dry air are condensed and discharged to the pipe 17. After the drying operation of the pipe 1 is completed, air containing steam of light water is taken in from the pipe 13 and supplied into the pipe 1. Tritium contained in heavy water adsorbed on the inner surface of the pipe 1 isotope-exchanged with hydrogen contained in vapor of light water, and is removed from the inner surface of the pipe 1. Light water and tritium water vapor are cooled in the condenser 4 and removed as water. Dry air and air containing light water vapor are 200 Since the temperature is lower than 0 ° C., tritium dissolved in the pipe 1 remains confined in the pipe 1. |
