IMPROVEMENTS IN AND RELATING TO NUCLEAR REACTOR FUEL ELEMENTS

Patent ·
OSTI ID:4107650
The end closure for reactor fuel elements consisting of uranium clad with an alloy of low strength properties, e.g., magnesium alloys, is designed so that the stresses on the weld from handling operations are reduced. This reduction is brought about by constructing the end closure member with a projection of reduced cross section on the side away from the fuel element: the container wall is pressed into contact with the projection to form a shoulder which bears stresses from lifting or lowering the fuel element, and the abutting edges of the container and end closure member are welded.
