Abstract

Reducing the volume of radioactively loaded liquids, particularly evaporator concentrates, by heating in a storage container up to solidification, wherein liquids are replenished for filling up the storage container. Heating takes place discontinuously in heating periods separated from each other in time. The heat is introduced directly into the container contents. Vapors produced are drawn off intermittently.
