Using a 300-ton vertical hydraulic extrusion press, fuel bars are clad with aluminum by direct extrusion. Previous nickel plating of the fuel, and possibly a copper fiash as well, is found to improve the bonding and also prevents oxidization when hented in the press. When extrusion begins a solid aluminum ribbon is first formoed and as the leading edge of the fuel bar moves forward in the press the sheath is formed round it as a continuation of the ribbon. A second solid ribbon at the rear end of the bar seals the sheath and continues to be formed until the arrival of the next element. Thus the operation may be repeated indefinitely to form a series of elements.
