Estimating the term…
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).
Packing device for transport of dangerous packages comprising a body delimiting at least one inside compartment opening onto one face of said body, an individual closure plug adapted to close each compartment, and a cover covering the plugs and working in conjunction with said face by external, intermediate and internal seals that simultaneously surround all plugs, the cover being fitted with a first connector adapted to be connected to a pressurized tracer gas source and opening up between the inner and intermediate seals, and a second connector adapted to be connected to means of creating a vacuum and detecting a tracer gas, and open into a space between the intermediate and external seals.
