The assembly is also configured so that if the assembly falls in the direction (12) with the first portion (14) of the frame pointing forwards, this causes a rupture of the fusible elements (30) allowing a movement of the entity (18) relative to the first portion (14) in direction (12). ## Claims ### Claim 1 Assembly including a package for transport of radioactive materials and a package support frame, wherein the frame includes: a first portion; a second portion which is rigidly attached to the package, wherein the package and the second portion form an entity, wherein the first portion and the second portion of the frame are connected to one another by one or more mechanical fusible elements, wherein under normal transport conditions said one or more mechanical fusible elements hold one of the first portion and the second portion of the frame relative to the other in a first direction of superposition of the package on its frame, in order to avoid movement of said second portion, through gravity effect, relative to said first portion in said first direction of superposition, and wherein the frame is configured so that a fall of the assembly in said first direction with the first portion of the frame arranged in front of the entity in this first direction causes a rupture of said one or more mechanical fusible elements allowing said entity to move relative to said first portion, in said first direction. ### Claim 2 (depends on 1) Assembly according to claim 1, wherein the first and second portions of the frame comprise guidance means allowing said entity to be guided, at least during a part of said relative movement, relative to the first portion in said first direction. ### Claim 3 (depends on 1) Assembly according to claim 1, wherein said package includes shock-absorbing means configured so that during said fall on a flat impact surface (S) orthogonal to said first direction, said rupture of each mechanical fusible element occurs before contact of the shock-absorbing means with the impact surface. ### Claim 4 (depends on 1) Assembly according to claim 1, wherein each mechanical fusible element takes the form of a shearing device. ### Claim 5 (depends on 1) Assembly according to claim 1, wherein it is configured so that after rupture of each mechanical fusible element, said entity is free relative to the first portion of the frame. ### Claim 6 (depends on 1) Assembly according to claim 1, wherein it is configured so that after rupture of each mechanical fusible element, said entity remains connected to the first portion of the frame by one or more plastically deformable connecting elements, during said relative movement. ### Claim 7 (depends on 1) Assembly according to claim 1, wherein said first portion of the frame includes uprights. ### Claim 8 (depends on 1) Assembly according to claim 1, wherein the second frame portion includes two structures surrounding a body of the package. ### Claim 9 (depends on 8) Assembly according to claim 8, wherein each structure is formed using two portions that may be disassembled, each extending over roughly 180°. ### Claim 10 (depends on 8) Assembly according to claim 8, wherein the two structures are installed by sliding in a guided manner in said first direction on uprights in the form of rails on said first portion of the frame, wherein the two structures are held on said uprights by the one or more mechanical fusible elements. ### Claim 11 (depends on 1) Vehicle for transporting radioactive materials, comprising the assembly according to claim 1, wherein the vehicle includes a platform for attaching the assembly superposed on said platform in said first direction, with the first portion of the frame attached to said platform. ### Claim 12 (depends on 3) The assembly according to claim 3, wherein said shock-absorbing means are shock-absorbing caps fitted at ends of the package. ### Claim 13 (depends on 4) The assembly according to claim 4, wherein said shearing device has a mechanically weakened portion. ### Claim 14 (depends on 7) The assembly according to claim 7, wherein said uprights are in the form of rails extending longitudinally in said first direction. ### Claim 15 (depends on 8) The assembly according to claim 8, wherein said two structures are annular structures.
