Six rode of uranium oxide were extruded at high temperature to produce high-density oxide of desirable stoichiometry. Four extrusions were produced from 1.5-inch billet cores, two at reductions of 12x, and two at reductions of about 20x. Two other extrusions were performed directly in stainless steel from 0.875-in. billet cores at reductions of 12x without an inner sheath of graphite or tamtalum. The central problem now appears to be the roughness between the core and clad. Desirable results probably will be obtained if the stainless component is kept as stiff as in the tantalum extrusion and the core as bot as in the insulated extrusion. (For preceding period see NMI-2505.)
