Patent ID: 8716686

Claim:
Canister for transporting and/or storing radioactive materials, said canister comprising a lateral body extending around a longitudinal axis of said canister, said lateral body forming a cavity for housing radioactive materials and comprising an inner metal shell and an outer metal shell, the two shells being concentric and forming jointly an annular space inside which is housed a radiological protection device forming a barrier against gamma radiation, said radiological protection device comprising at least one first and one second metal radiological protection components adjacent along a circumferential direction of the canister, characterised in that said first component is supported against the outer shell and at a distance from said inner shell, whereas said second component is supported against the inner shell and at a distance from said outer shell, and in that said first and second components are in contact with each other along an interface taking, in section along any plane orthogonal to the longitudinal axis and crossing this interface, the form of a straight line segment defining with a radial straight line crossing it at its centre an acute angle (A), wherein the first and second components are distinct, and wherein the contact force between said first and second components at the interface radially constrains the first and second components against the outer shell and inner shell, respectively.
