Fabrication of zirconium-clad uranium fuel elements
Technical Report
·
OSTI ID:4185841
Zr-clad U rods are being produced on a small scale by simultaneous extrusion. A U billet is machined and the surface carefully prepared by pickling. An extruded Zr tube is shrunk or pushed on the U slug. The assembly is machined to give the proper thickness of cladding and is then extruded in a protective jacket. The jacket is removed chemically or mechanically, and the element is given a slight cold finish by swaging to obtain surface and dimensional tolerances. Even claddings are obtained, and mechanical and thermal cycling tests show that a strong bond exists. (J.R.D.)
