    Abstract: Radioactive wastes are treated in a furnace which has electrodes for electric heating. The furnace has at the lower end an outlet for slag material as well as a gas discharge line. Its well is a self-supporting tubular body which is arranged detachably in a metal furnace housing. At the upper end of the well is a line for feeding water. Thereby, carbon-containing waste, possibly also carbon of a carbon bed, is reacted to form water gas (CO+H.sub.2), which is burned after purification in an exhaust gas plant. The outlet of the metal housing has a movable grate.

    Abstract: An apparatus for treating ion-exchange resin includes a disk mill having a plurality of disks including corundum for comminuting the ion-exchange resin. Reliable temporary storage or final storage even of coarse-grained ion-exchange resin from a nuclear plant is made possible by reduction of the swelling capacity.

    Abstract: A drying station with low energy consumption and short drying time for drying liquid or damp waste, especially contaminated waste from a nuclear power station, includes at least one heating mat for delivering heat of evaporation into a container in order to fully and reliably ensure the drying of material in the container. A retainer automatically produces a large-area mechanical contact between the heating mat and the container when the container is brought into a drying position.

    Abstract: For bonding particularly radioactive wastes into a binder, a transporting and mixing device is used which transports the mixture to a storage tank prior to the hardening. The wastes are transported into the mixing zone by gravity and aided by the conveyor helix which also imparts additional wall cleaning action through the dry conveyor zone. A single or multi-component binder is concurrently transported in a direction lateral to the mixing tool to the mixing zone. The mixture is conducted in a straight-line extension of the transport and mixing direction to an outlet to which the storage tank is connected.
