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).
Claims14
A very long-term storage installation for calorific products, comprising at least one sealed cavity, at least one container to confine said products, said container being housed in said cavity, and thermosiphon-forming means able to dissipate above the cavity the heat released by said products, wherein a jacket surrounds and is in direct contact with the container, said jacket partly integrating the thermosiphon-forming means,
- wherein a space is provided inside the cavity, around the container fitted with the jacket.
A very long-term storage installation for calorific products, comprising at least one sealed cavity, at least one container to confine said products, said container being housed in said cavity, and thermosiphon-forming means able to dissipate above the cavity the heat released by said products, wherein a jacket surrounds and is in direct contact with the container, said jacket partly integrating the thermosiphon-forming means,
- wherein the jacket comprises a plurality of outer tubes filled with coolant liquid and leading respectively to a lower ring collector and an upper ring collector,
- wherein the cooling vanes are formed on at least some of the outer tubes.
A very long-term storage installation for calorific products, comprising at least one sealed cavity, at least one container to confine said products, said container being housed in said cavity, and thermosiphon-forming means able to dissipate above the cavity the heat released by said products, wherein a jacket surrounds and is in direct contact with the container, said jacket partly integrating the thermosiphon-forming means,
- wherein the jacket comprises a plurality of outer tubes filled with coolant liquid and leading respectively to a lower ring collector and an upper ring collector,
- wherein the jacket comprises a plurality of segments fixed end to end by assembly means, each of the outer tubes being made in a single piece with one of said segments.
