Abstract
To provide a device for removing radioactive cesium from waste material containing radioactive cesium, doing so at low energy and in a dependable manner. The removal devicefor radioactive cesium is provided with: a rotary kilnwhich is provided with a burnersupplying from the kiln outlet an organic matter Ocontaminated with radioactive cesium, and an inorganic matter charging portsupplying from the kiln inlet inorganic matter Scontaminated with radioactive cesium, and which is employed to burn the organic matter Otogether with the inorganic matter S; and a recovery device cooling tower, a cyclone, a bag filterfor recovering cesium that has volatilized in the rotary kiln. A drying/crushing device (dryer, crusher) for drying and crushing the organic matter Oprior to charging the radioactive cesium-contaminated organic matter to the rotary kiln can be provided. Additionally, a reforming/drying/crushing device (reformer, dryer, crusher) for reforming, drying, and crushing the inorganic matter Scan be provided. During burning of the organic matter Otogether with the inorganic matter S, a calcium source can be added as a reaction accelerant A to the rotary kiln.
