Abstract

A shielded container for the treatment of radioactive waste has an upwardly open cast-iron vessel having a closed bottom, solid walls unitary therewith, and an open upper mouth itself closed by a cast-ion lid which is formed with separate vertically throughgoing intake and outlet passages. Screwthread formations either provided directly on the lid and vessel or on fasteners engaged between them hermetically secure the lid over the mouth. A flow deflector aligned inside the vessel underneath the outlet passage can be formed as a plate so aspirated gases do not entrain liquid or solid particles. A single cover is held by appropriate screwthread formations on the cover over the passages. The vessel can be relatively thin--8cm, 12cm, or 18cm--cast iron so it is possible to treat its contents. For drying radioactive wastes it is merely necessary to heat the outside of the container while applying suction to the outlet passage.
