METHOD OF MAKING COMPOSITE FUEL ELEMENTS
Patent
·
OSTI ID:4107690
A method for joining the sections of a composite fuel blanket element for a fast breeder reactor and for capping the ends of a fuel element consisting of a uranium rod clad in Zircaloy-2 is outlined in which the exposed uranium is etched to the depth of yields 1/10 mil, a thin disk of zirconium is placed between the ends to be joined, pressure is applied to the joint, the joint is welded with an inert gas-shielded arc to fuse the cladding to 50% of its thickness, and the joint is heated by induction to form a diffusion bond between the uranium and the zirconium disc. A specific example of this method and welding conditions is presented. (D.L.C.)
