Embodiment Construction

[0044] figure 1 Very succinctly shown part of a facility for the long-term storage of exothermic products, such as nuclear waste, constructed according to the invention.

[0045] This device comprises at least one closed cavity 10 , for example a trench dug in the ground, whose sides and bottom are formed by concrete walls 12 .

[0046] In the embodiment described, the cavity 10 is in the shape of a rectilinear trench buried in the ground. This trough can accommodate a plurality of containers 14 in which the product to be stored is contained. However, the shape of the cavity 10 may be different without departing from the scope of the present invention. Thus, each container 14 can be placed in a different single cavity.

[0047] Likewise, the container 14 used to seal the product to be stored is a metal container which may vary in shape and size without departing from the scope of the invention. In the illustrated embodiment by way of example, the containers 14 are cylindri...

Abstract

A very long term storage installation for calorific products such as nuclear waste, comprises at least one closed cavity (10), in which at least one product confinement container is housed (14). To evacuate the heat released by the stored products, each container (14) is surrounded by a jacket (26) associated with a thermosiphon (24) whose cold source is formed of an air condenser provided above a slab (20) sealing the top part of the cavity. The jacket (26) is preferably interchangeable and tightly surrounds the container (14).

Description

field of invention [0001] The invention relates to a device for ensuring the long-term storage of exothermic products, such as products which emit a large amount of heat, which decreases with time (dans le temps). [0002] The term "storage" refers to the reversible storage of a packaged product with the function of discharging the heat emitted by the product. The adverb "reversibly" means that the stored product can be taken out of storage. [0003] The word "long term" means at least fifty years, preferably several fifty years. [0004] A preferred application of the apparatus according to the invention is in connection with the storage of nuclear waste which is highly radioactive for a long period of time, for example irradiated fuel in nuclear reactors. Background technique [0005] Storage of hazardous heat-generating products, such as nuclear waste, is a major problem for which several solutions have been proposed. [0006] Among these solutions, only those that gua...
