Research on desactivation of liquid, solid and gaseous radioactive wastes and decontamination of surfaces. Proceedings of the 4-th scientific and technical conference of CMEA. Moscow, 20 - 23 december 1976

The results of research works done in the field of desactivation of liquid radioactive wastes of low and medium activity are described. Problems of desactivation of sewage from nuclear power plants and other nuclear installations are discussed. The results of efficiency estimation of different methods of sewage radioactivity lowering are discussed including such chemical methods of purification os coprecipitation and coagulation. Problems of application both the organic and the nonorganic sorbents for separation of radioactive substances from liquid wastes are discussed. Results of research on purification methods by electrodialysis and ion exchange are given. More that this, the results of experiments on evaporation of liquid radioactive wastes and problems of long time storage of highly concentrated liquid wastes are discussed. (I.T.)
