Abstract:
1. 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, wherein said radiological protection device comprises at least one first and one second metal radiological protection components superimposed along a radial direction of the canister, said first component being supported against the inner shell and said second component being supported against the outer shell, wherein said first and second components are in contact with each other along an interface taking, in section along any plane passing through said interface and integrating the longitudinal axis, the form of a straight line segment inclined in relation to this axis, and wherein the inclined straight line segment is inclined at a non-zero angle with respect to the longitudinal axis, wherein the first and second components are wedged between the inner metal shell and the outer metal shell, wherein the first component is in direct surface contact with an outer diameter of the inner metal shell and the second component at the interface, and wherein the second component is in direct surface contact with an inner diameter of the outer metal shell and the first component at the interface, and wherein the position of each of the first and second components between the inner metal shell and the outer metal shell is maintained only by the direct contacts between the inner metal shell, first component, second component and outer shell in the annular space.
