Abstract

A container or transporting irradiated fuel elements, in which the internal space is filled with liw. to bring about transfer of heat by convection to the outer wall, incorporates a buffer capacity in the internal space. The buffer capacity is at least partly filled with air or other gas. It connects with the internal space through a pipe arranged so that the buffer capacity compensates automatically for changes in press. caused by changes in temp.; without allowing the air or gas to attain the internal space. Problems associated with the elements not being completely submerged are avoided. These problems arise from the fact that the part in the air pocket is insufficiently cooled and is subject to alternate immersions and exposures to the air phase, due to the movements of the vehicle. These changes can engender thermal shocks and internal stresses in the elements and breaking off of contaminated particles which remain in the container.
