METHOD OF DECONTAMINATING MATERIALS |
摘要 |
FIELD: physics.SUBSTANCE: decontamination is performed in two steps: at the first step, steam activated with chemical reagents is fed into a decontamination chamber with contaminated materials heated to 110°C; at the second step, the decontamination chamber is cooled and the decontaminated material is treated with solutions of organic solvents and complexing agents in a medium of liquefied gases or low-boiling solvents. The method may involve successively using multiple treatment cycles, alternating the first and second steps.EFFECT: high decontamination efficiency, increasing the decontamination factor 4-30 fold compared to a single-step decontamination method in supercritical fluids, low operating pressure and volume of liquid radioactive wastes and shorter decontamination time.3 cl, 1 dwg |
