Abstract: A method for treatment of spent ion-exchange resins for disposal includes feeding a mixture of spent ion-exchange resins to the a loading tank, separating the ion-exchange resins, feeding separated ion-exchange resins into the a drying chamber, vacuum drying the ion-exchange resins and subjecting the resins to additional heat treatment in a high-temperature furnace, and unloading the treated ion-exchange resins into a transport container. A device for treatment of spent ion-exchange resins includes a loading tank, a metering device connected to a drying chamber, an inclined feed screw located between the loading tank and the metering device, a vacuum pump, a heated gas filter, a high-temperature furnace equipped with a vacuum drying and gas purification system, and a feeding device located between the drying chamber and the high-temperature furnace. A docking unit is connected to a lower part of the high-temperature furnace.

Abstract: The invention relates to the reprocessing of spent ion-exchange resins at nuclear power plants or special plants. The invention involves microencapsulation of ion-exchange resins (immobilization of radionuclides inside microcapsules), reducing the volume of discharged ion-exchange resins and preventing their swelling when exposed to moisture. A method for treatment of spent ion-exchange resins for disposal comprises feeding a mixture of spent ion-exchange resins to the loading tank, separating the ion-exchange resins, feeding separated ion-exchange resins into the drying chamber, vacuum drying of the ion-exchange resins, unloading the treated ion-exchange resin into a transport container. The ion-exchange resins after vacuum drying are subjected to additional heat treatment in a high-temperature furnace and unloading treated ion-exchange resin in a transport container.
