Abstract
(EN)
The invention relates to an assembly (100) comprising a packaging (1) for storage of radioactive materials, as well as the support system (3) thereof, comprising a radiative screen (20) for thermal protection of the ground, this screen comprising at least one air passage (24) providing the communication between a zone (32) for circulation of air for cooling the ground defined under a first face (28) of the screen, and a zone (34) for circulation of air for cooling the bottom of the packaging defined between the second face (30) of the screen and the bottom of the packaging (4). The support system (3) comprises elements (36) for supporting the bottom of the packaging, each projecting from the second face (30) of the radiative screen (20) and extending through the zone (34), and it also comprises bearing elements (38) projecting into the zone (32).

L'invention se rapporte à un ensemble (100) comprenant un emballage (1) d'entreposage de matières radioactives, ainsi que son système de support (3) comprenant un écran radiatif (20) de protection thermique du sol, cet écran comportant au moins un passage d'air (24) assurant la communication entre une zone (32) de circulation d'air de refroidissement du sol définie sous une première face (28) de l'écran, et une zone (34) de circulation d'air de refroidissement du fond d'emballage définie entre une seconde face (30) de l'écran et le fond d'emballage (4). Le système de support (3) comprend des éléments de support (36) du fond d'emballage, chacun faisant saillie de la seconde face (30) de l'écran radiatif (20) et s'étendant à travers la zone (34), et il comprend également des éléments d'appui (38) faisant saillie dans la zone (32).
