Title: FUEL CONTAINER CLOSURE

Abstract

A method of producing a spherical closed end on a small thin-walled tube forming a container for reactor fuel is described. An end cap inserted in the tube has a long slender external projection extending axially of the tube. A heavy electrical current is applied to the projection, and simultaneously a portion of the tube very near the end cap is chilled. A part of the projection is vaporized, and the balance is melted, along with portions of the end cap and the tube. As a result, the end cap is welded to the tube, and the projection in melting is spread out to form a spherical surface on the end cap. (AEC)
