ABSTRACT:
A transport and storage container for low and medium level radioactive wa is sealed with an external cover after being charged with a receptacle insert. The receptacle insert has a cup-like configuration and is arranged in the storage container and adapted directly to receive the radioactive waste. The storage vessel and the receptacle insert conjointly define an annular space therebetween. The storage container must be appropriate for remotely-controlled handling and must have the greatest possible capacity per drum. For this purpose the top of the receptacle insert has a radially extending centering ring at the edge of its opening with segment-like recesses disposed in spaced relationship to each other around its periphery. The wall of the insert tapers downwardly toward the base thereof. A supporting ring extends around the outer periphery and is arranged on the external surface of the insert in spaced relationship to the centering ring and its outer diameter is greater than the inner diameter of the centering ring. The invention is also directed to a method of charging such a container for low and medium level radioactive waste.
