An experimental setup for dewatering melts of salts of radioactive wastes has been developed at the Moscow Engineering Physics Institute (MIFI). Induction heating of the working chamber with the material being processed and vacuum pumping of water vapor were used. An evaporation rate of free water 11.25 liters/h was achieved in the course of the experiments. Experiments on dewatering of a simulator of a melt of liquid radioactive wastes from NPP with initial moisture content 31.9 wt.% were performed. The content of bound water in the final sample was 5%. There was no free water. The setup can process liquid radioactive wastes in the form of melt and bottom residues in batch and continuous regimes.
