Abstract: Shielding container assembly for storing weak to medially active waste in a storage barrel, including a shielding container having a substantially square cross section surrounding the storage barrel, the shielding container having two pairs of oppositely-disposed sections, one of the pairs having symmetrical projections formed thereon and the other of the pairs having chamfers formed thereon, the projections and chamfers effecting anchoring of the containers when stacked close to each other.

Abstract: Method of removing radiant, pulverulent synthetic wastes which are mixed dry with a thermoplastic mass in a kneader and then delivered from a discharge opening of the kneader into a container capable of providing a final storage therefor, while gases and/or vapors are withdrawn from degassing domes of the kneader, which includes delivering fluidic dried wastes by mechanical movement through a metering tube into a degassing dome in the kneader disposed next to the discharge opening, and admitting scavenging gas into the metering tube at least temporarily in direction toward the kneader; and device for carrying out the foregoing method.
