1,165,866. Nuclear fuel. UNITED STATES ATOMIC ENERGY COMMISSION. 22 July, 1968 [24 July, 1967], No. 34910/68. Heading G6C. Uranium dioxide-columbium cermet nuclear fuel is preferred as described in Specification 1,161,648 except that particulate carbon is mixed with the particulate columbium in order to react with oxygen impurities in the UO 2 and columbium; after de-waxing of the compact, the oxygen impurities are removed as CO by heating under vacuum to about 1700‹ C. for one hour. The product has greater ductility and higher density than that produced without using carbon. |
