A shipping container for the transport and storage of highly enriched uranium.

Well-known a shipping container (US patent, 4147933, G 21 F 5/00, 1979), which contains the drum, located in the inner container and insulating material located between the drum and the inner container. Known container does not provide the necessary security during the transportation of highly enriched uranium.

The technology is highly enriched uranium.

A shipping container for highly enriched uranium contains a drum with a lid, which is a container equipped fixed on the cover, and insulation material located between the drum and the container. Insulation material made in the form of consecutive first layer of fibreboard, the first layer of plywood, open at both ends of the cylinder fibreboard placed between the container and the drum, the second layer of plywood and a second layer of fibreboard, with the first layer of fibreboard and the first layer of plywood to cover the bottom of the drum and the container holds the pilot hole. The transport container may further comprise a bracket located on the inner container. The inner container can be made of austenitic stainless steel. The inner container may contain a device for securing the cover to the inner container by bolts and o-ring located in the groove made in the lid. The pilot hole can be made in the cover between the two grooves. Cover of the inner container may be provided with a damping element located in the center of the cover. OBrien side view in section with a partial tear-out image; in Fig. 2 is a side view in section of the inner container for the image.

The transport container 10 includes a drum 12, the inner container 14, a sealing cover of the inner container 16 and means 18 for securing the cover 16 to the inner container 14. Strip the insulation material 22 consists of a first layer of fibreboard 24, is designed so that it covers the bottom of the drum, the first layer of plywood 26 having dimensions enabling it to be placed in the dryer on top of a layer of fibreboard, cylinder 28 fibreboard, open on both sides. The internal dimensions of the cylinder such that the inner container 14 fits tightly into him. The second plywood layer 30 is placed on top of the cylinder fibreboard, the second layer of fibreboard 32 is located on the top layer of plywood. The drum is fitted with a cover 34, closing it firmly. The inner container 14, shown in Fig. 2, provided with flanges 38. In the sealing cover 16 made the pilot hole 36, to allow inspection before every shipment. The means 18 for securing the cover 16 to the inner container 14 and the formation of an airtight seal between them is a ring 42, to the s 50. In a preferred embodiment, the circumference of the flange 38 are eight holes with threads 46, and the cover 16 has corresponding holes 48 for securing the cover 16 by bolts to the inner container 14. Cover 16 is equipped located in the middle of the damping element 41 that is placed inside the inner container 14 to 3 mm (preferred value). In a preferred embodiment, the cover 16 is provided with two annular grooves 44. The sealing ring 42 is fixed in the groove 44 so that between the cover 16 and the inner container 14 is formed seal when attaching the cover 16 by bolts to the inner container. The pilot hole 36 forms a passage through the cover 16, which is located between the sealing rings and allows you to check for leaks after closing the lid 16 on the container. The o-ring closest to the inner part forms a primary seal. The cover 16 is a bracket manipulation 52, which is the remote manipulation of the container 14 when it is loaded and unloaded from the drum.

Transported highly enriched uranium may be in the form of solid particles, granules, tablets, paraskara bolts the cover 16 so the pressure on the sealing ring creates a tight seal between the cover 16 and the container 14. Then the locking washer 54 installed between the heads of the bolts and the cover 16, is bent upward so that the bolts 50 does not come loose during transport. Then to the bracket 52 for manipulating attach lifting equipment designed for remote lifting to lift and set the container 14 in the drum 12, which is lined inside with insulating material. During transport pilot hole 36 is closed.
