USE OF ADDITIVES FOR VITRIFICATION OF LIQUID RADIOACTIVE CESIUM RADIONUCLIDES-CONTAINING WASTES HAVING HIGH RETENTION EFFICIENCY OF SAID RADIONUCLIDES OVER THE ENTIRE RANGE OF VITRIFICATION TEMPERATURE
The present invention relates to additives for the vitrification of liquid radioactive wastes containing cesium radionuclides, the additives having high retention efficiency of said radionuclides over the entire temperature range of the vitrification process and comprisingmetakaolin and anhydrous sodium silicate and/or anhydrous potassium silicate as ingredients of a homogeneous powder mixture or a dry granulate. The ingredients are in close contact and their grain size is at least on the micron level. The additives can further comprise inorganic hydrophilic materials and/or a fluxing agent. The invention also includes a method of preparing said additives and also use of said additives for immobilisation of cesium radionuclides in the process of vitrification of liquid radioactive waste over the entire temperature range of the vitrification process. Cesium radionuclide is preferably 137Cs radionuclide.
