FIELD: power industry.
SUBSTANCE: device for curing liquid radioactive waste contains a container with a stirring stirrer, feeding units for LRW and filler. The container is connected to the LRW feed unit by a pipeline, with the filler supply unit via a screw feeder. The container is additionally connected by an installed screw feeder with a thermostated process vessel, in the lid of which there is a nozzle for introducing a filler solution, preferably a diatomite, an inlet pipe for the radiator of the connected ultrasonic station and a branch pipe for gas and liquid vapour discharge. In the cavity of the additional tank a dual-mode heater is mounted, a removable tray is installed inside it. Ferrocyanide or aerosol filters are connected in the upper gas part of the condenser, and in its lower part - a valve for drainage of liquid condensate.
EFFECT: invention allows to replace cement with dispersed diatomite, which has high parameters of binder material.
