  • Transport packing for dangerous packages such as high activity nuclear packages
    Patent number: 6114710
    Abstract: Dangerous packages, such as high activity nuclear packages, are placed in adjacent compartments (22) formed in the body (10) of transport packing. The compartments (22) are closed by individually closure plugs (28) and by a common cover (34) that works in cooperation with one face (17) of the body (10) with three seals in series. Connectors installed on the cover (34) and opening up between the seals, are used to make an inspection of the helium confinement. The steel inner casing (24) in each compartment (22) is doubled up on the outside with a copper weld free casing (50). This arrangement significantly improves the confinement inspection, enables a global helium inspection, and if necessary can be used to isolate an unsealed compartment (22).
