ABSTRACT Radioactive waste, such as expended radioactive ion exchanger mass, can be transformed in a continuous process to a stable state for final storage in the following manner. The waste is mixed with an aqueous solution of a chemical agent which liberates radioactive substances from the waste, and with an inorganic sorbent for the thus liberated radio- active substances. The mixture is now dried and calcinated during the supply of air or oxygen so that the organic material is combusted. Subsequently the calcined material is placed in a refractory storage container, which is now heated with its contents to a temperature at which said material sinters or fuses to a stable product.
