Title
(EN) STORAGE CONTAINER FOR RADIOACTIVE MATERIALS HAVING A SIMPLIFIED DESIGN PROVIDING IMPROVED HEAT TRANSFER PROPERTIES
(FR) PANIER DE RANGEMENT POUR MATIÈRES RADIOACTIVES, À CONCEPTION SIMPLIFIÉE CONFÉRANT DES PROPRIÉTÉS AMÉLIORÉES DE TRANSFERT THERMIQUE
Abstract
(EN)
The invention relates to a storage container (1) for radioactive materials (2), the container defining one or a plurality of housings (4) for receiving radioactive material (2), the container comprising a plurality of transverse plates (20) distributed along the longitudinal central axis (6) of the container, each transverse plate (20) comprising a main plate portion (26) oriented orthogonally with respect to the longitudinal central axis (6) and having one or a plurality of through-holes (24) for the radioactive materials (2) to pass through. According to the invention, at least one through-hole (24) of at least one of the transverse plates (20) has, on the main plate portion (26), an opening outline (32) from which at least one folded heat transfer plate portion (30) projects axially from the main portion (26).

L'invention concerne un panier de rangement (1) pour matières radioactives (2), le panier définissant un ou une pluralité de logements (4) destinés à recevoir des matières radioactives (2), le panier comportant une pluralité de plaques transversales (20) réparties le long de l'axe central longitudinal (6) du panier, chaque plaque transversale (20) comprenant une portion principale de plaque (26) orientée orthogonalement à l'axe central longitudinal (6) et présentant un ou une pluralité d'orifices de passage (24) destinés à être traversés par les matières radioactives (2). Selon l'invention, au moins un orifice de passage (24) d'au moins l'une des plaques transversales (20) présente, sur la portion principale de plaque (26), un contour d'orifice (32) à partir duquel s'étend au moins une portion de plaque repliée de transfert thermique (30), en saillie axialement à partir de la portion principale (26).
