FABRICATION AND PROPERTIES OF EXTRUDED SILVER-CADMIUM CONTROL RODS
The production of cross-type control rods having a span of 4- 7/8 in., and an arm thickness of 1/8/ in., was studied. Extrusion techniques were developed for producing crosstype control rods from each of two alloys; one containing 75% silver-25% cadmium, and the other containing 67% silver-30% cadmium-3% copper. Fabrication of the extruded crosses into clad control rods for the Mark I naval reactor was attempted. A set of unclad control rods for the Zero Power Reactor was produced. The effect of copper, nickel, aluminum, palladium, and indium, singly and in various combinations, on the physical and mechanical properties of silver-cadmium was studied. Data are given on the work hardening and annealing of binary silver-cadmium alloys, and on the precipitation hardening of certain complex silver-cadmium alloys. A materials specification and suggested fabrication procedure were established for nickel-clad extruded silvercadmium control rods. (auth)
