Abstract
The incineration is one of the widely used method for treatment of solid radioactive wastes. The high volume and weight reduction coefficient (100–150 respectively 10–15) are advantages of this method. The greater part of radionuclides from solid radioactive wastes is retained in ash. From point of view of workers external irradiation, the radionuclides accumulation in furnace lining is one of risk factors. The Kalinit ŽO 1200 is furnace lining material on NPPRIs Experimental Incineration facility. In the first step the sorption properties of this material from137Cs,60Co,54Mn,65Zn solutions were studied. The best results had60Co, its distribution coefficient was 7036 kg · dm−3. Cesium-137 was not absorbed on this material. The cylinders (height 5 cm, diameter 2 cm) from lining materials were made latest and were applicated inside the furnace and technological tract to study sorption properties from combustion gases. The penetration of radionuclide into lining material was studied too. The results obtained with this experiments are described in this paper.
