FIELD: power industry.
SUBSTANCE: thermochemical treatment of resins is performed in salt fusion diluted with sulphuric acid in three stages at temperatures of 100-150°C, 150-250°C and 250-350°C and at atmospheric pressure in the device, in conditions of free air access to reaction zone, at constant or periodic mixing of the product in the device, and final solidification of the obtained dry product is performed by means of binding agents of phosphate hardening (natural minerals or wastes of industrial enterprises, which contain metal oxides).
EFFECT: maximum possible decrease of volume and weight of solid radioactive wastes, simplifying the technology and reducing power consumption.
