Section: claims

1. Shielding container assembly for storing weak to medially active waste in a storage barrel, comprising a plurality of shielding containers each having massive concrete walls in a substantially square cross section surrounding the storage barrel, each shielding container having two pairs of oppositely-disposed sections, one of said pairs having symmetrical projections formed thereon with a given shape extended outward from said substantially square cross section and the other of said pairs having recesses with said given shape formed therein extended into said substantially square cross section, each of said projections being releasably anchored in a respective one of said recesses of an adjacent shielding container when stacking said shielding containers in a horizontal row. 2. Shielding container assembly according to claim 1, wherein said projections and chamfers are disposed at corners of said shielding container. 3. Shielding container assembly according to claim 2, wherein said projections and chamfers are in the form of symmetrical pairs. 4. Shielding container assembly according to claim 1, wherein said shielding container has a clearance space formed therein for receiving said storage barrel, said space extending through the total height of said shielding container. 5. Shielding container assembly according to claim 4, wherein said clearance space has a cylindrical cross section and is centrally disposed in said substantially square cross section of said sheilding container. 6. Shielding container assembly according to claim 1, wherein said shielding container has top and bottom surfaces thereon, said surfaces having raised portions formed thereon and having recesses formed therein in which said raised portions fit. 7. Shielding container assembly according to claim 6, wherein said raised portions are disposed at four corners of said square cross section of said shielding container. 8. Shielding container assembly according to claim 6 or 7, wherein said shielding container has undercuts formed therein at said recesses for attachment of gripper tools. 9. Shielding container assembly according to claim 8, including reinforcements being disposed in said undercuts and extended into said shielding container. 10. Shielding container assembly according to claim 1, including a storage chamber having straight walls with recesses formed therein, said projections being extended into said recesses. 11. Shielding container assembly for storing weak to medially active waste in a storage barrel, comprising a plurality of shielding containers each having massive cast iron walls in a substantially square cross section surrounding the storage barrel, each shielding container having two pairs of oppositely-disposed sections, one of said pairs having symmetrical projections formed thereon with a given shape extended outward from said substantially square cross section and the other of said pairs having recesses with said given shape formed therein extended into said substantially square cross section, each of said projections being releasably anchored in a respective one of said recesses of an adjacent shielding container when stacking said shielding containers in a horizontal row.
