Abstract
Liquid radioactive wastes are concentrated to form a pasty radioactive concentrate by evaporation below the boiling point of the waste by injecting a hot gaseous medium tangentially in a vortex stream over the entire surface of the liquid waste, thereby entraining vapor evaporated from the liquid surface, removing the gaseous medium together with the entrained vapor, drying and reheating the removed gaseous medium and recirculating it in a vortex stream over the surface of the waste, which may then be stored in the same container in which the evaporation took place.
