RADIATION SHIELDING AND HEAT INSULATION DEVICE

Disclosed in the present invention is a radiation shielding and heat insulation device, comprising an annular top plate, which is fitted on the top of a container; a shielding unit, which is connected below the annular top plate, arranged on the periphery of the container in a surrounding manner and used for shielding neutrons and γ rays; and a heat insulation layer, which is arranged below the top plate and fixedly attached to an inner side of the shielding unit so as to coat the periphery of the container. The radiation shielding and heat insulation device in the present invention is used for covering an upper portion of a spent fuel transfer container or transport container, has the functions of radiation protection and high-temperature heat insulation, and solves the technical problems of a high radiation dose/radioactive substance contamination, a high operation temperature, etc. that are present during a spent fuel loading operation. La présente invention divulgue un dispositif de protection contre les
