DEVICE FOR SOLIDIFYING LIQUID RADIOACTIVE WASTES Russian patent published in 2003 - IPC

FIELD: recovery of high-activity solutions formed in spent nuclear fuel reconditioning. SUBSTANCE: device that functions to regulate liquid waste solidification process has drum for sorbent saturation and calcination. Drum is overhung from rotor on half-axle; it is offset relative to drive axis and disposed on turning platform that holds it in tilted condition in two positions one being working position and other, discharge position. Drum orifice is closed with fixed lid set at small clearance. Lid mounts halide lamp-heater base. Lamp placed in quartz bulb is disposed inside drum.
