Assembly for transporting uranium hexafluoride, comprising shock absorber caps

An assembly for transporting uranium hexafluoride, comprising:

• a sealed inner container, defining a first containment shell intended to be loaded with uranium hexafluoride, the sealed inner container having a general cylindrical shape of circular cross-section, the first containment shell being delimited by a lateral wall extending about a longitudinal central axis of the inner container, as well as by two opposite axial end walls crossed by the longitudinal central axis, at least one of the two opposite axial end walls of the sealed inner container being equipped with a uranium hexafluoride filling valve as well as with a protective annular axial extension of the uranium hexafluoride filling valve, the extension extending axially beyond the filling valve;
• a sealed outer container delimiting a second containment shell wherein the sealed inner container is housed in an extractable manner;
• and
• two shock absorber caps removably fastened on respectively two opposite axial ends of the sealed outer container.
