Abstract
A transport/storage container for spent nuclear-fuel elements has spaced inner and outer side walls defining an annular space extending along an axis, a cover at one end of the side walls, a floor at an opposite end of the side walls, and a plurality of heat-conducting elements in the space and each having one edge fixed, for instance by welding or bolting, to one of the side walls and an opposite edge bearing radially elastically on the other of the side walls.
Claims7
A transport/storage container for spent nuclear-fuel elements, the container comprising:
- spaced inner and outer side walls defining an annular space extending along an axis and having upper and lower ends
- a cover at the upper end of the side walls;
- a floor at the lower end of the side walls;
- and
- a plurality of sheet-metal heat-conducting elements in the annular space, each having one edge fixed to one of the side walls and an opposite edge bearing radially on the other of the side walls, and each having portions punched out from and extending at an acute angle to the respective heat-conducting element.
A transport/storage container for spent nuclear-fuel elements, the container comprising:
- spaced inner and outer side walls defining an annular space extending along an axis and having upper and lower ends
- a cover at the upper end of the side walls;
- a floor at the lower end of the side walls and including an inner floor wall connected to the inner side wall and an outer floor wall spaced from the inner floor wall and connected to the outer side wall;
- a plurality of side heat-conducting elements in the annular space and each having one edge fixed to one of the side walls and an opposite edge bearing radially on the other of the side walls;
- and
- a plurality of floor heat-conducting elements in the annular space between the inner and outer floor walls and each having one edge fixed to one of the floor walls and an opposite edge bearing axially on the other of the floor walls.
A transport/storage container for spent nuclear-fuel elements, the container comprising:
- spaced inner and outer side walls defining an annular space extending along an axis and having upper and lower ends
- respective inner and outer sets of axially extending U-shaped profiles fixed to the inner and outer side walls and having arms extending radially therefrom;
- a cover at the upper end of the side walls;
- a floor at the lower end of the side walls;
- and
- a plurality of heat-conducting elements in the annular space and each having one edge welded to respective arms of the profiles of one of the side walls and an opposite edge bearing radially on the arms of the profiles of the other of the side walls.
