Section: claims

1. A cylindrical container for the transportation of radioactive reactor elements, said container including a top end, a bottom end and a pair of removable outwardly curved shock absorbers each including a double-shelled construction having an internal shell and an external shell with a convex extrados configuration, said shock absorbers being filled with low density energy-absorbing material and mounted at said top end and said bottom end of the container, respectively, and each of said shock absorbers having a toroidal configuration, and deformable tubes disposed therein and extending in the axial direction of said container. 2. A container as claimed in claim 1, wherein said external shell is thicker than said internal shell. 3. A container as claimed in claim 2, wherein the container has a body, the internal and external shells are made from rustproof steel, said shells having rims which are welded to an annular flange which is secured to the container body. 4. A container as claimed in claim 3, wherein said deformable tubes have a thick-wall configuration and are welded to the external shell and to the annular flange. 5. A container as claimed in claim 1, wherein said container includes an outer casing which encloses a cylinderical annular chamber, said annular chamber including a water-filled chamber and a gas-filled expansion chamber positioned in spaced relation thereto, said gas-filled expansion chamber having a concentrically disposed metal bellows positioned therein. 6. A container as claimed in claim 5, wherein the ends of the annular chamber are closed by side ribs, said side ribs being deformable for absorbing kinetic energy. 7. A container as claimed in claim 1, wherein said container includes partially deformable lifting lugs which are disposed at said bottom and said top ends of the container for absorbing energy. 8. A container as claimed in claim 1, wherein said toroidal configuration has an axis, and said deformable tubes are arranged in a circle in said container about an axis concentric with the axis of said toroidal configuration. 9. A container as claimed in claim 1 wherein said internal shell has a convex intrados configuration.
