Abstract

L'invention concerne un agencement pour le transport d'un objet radioactif (11) de masse élevée et de grandes dimensions, comprenant une structure porteuse (10) recevant l'objet, avec des moyens de liaison (34, 36) pour un véhicule de transport (20). Afin de pouvoir transporter sans difficultés des objets radioactifs qui nécessitent un blindage supplémentaire afin de respecter les valeurs limites en termes d'intensité de dose, il est proposé que la structure porteuse (10) comprenne un cadre avec des longerons de cadre qui définissent sur leur circonférence un corps prismatique rectiligne et qui se composent de deux premiers longerons inférieurs de cadre (16, 18) et deux deuxièmes longerons supérieurs de cadre (12, 14). Les premiers longerons et les deuxièmes longerons sont reliés respectivement par des traverses (48, 50, 52, 54, 56) entre lesquelles l'objet peut être positionné, par endroits, par complémentarité de forme. À leurs extrémités, les premiers longerons portent des logements et les deuxièmes longerons, des surfaces de butée pour des bras de support (26, 28) d'un véhicule à col de cygne (20) servant de véhicule de transport.
