ALLOY MEMBERS SUITABLE FOR USE AS NUCLEAR FUEL ELEMENTS AND PROCESS FOR MAKING THE SAME
A uranium alloy exhibiting high resistance to corrosion by high- temperature water and steam and suituble for use as a fuel alloy in pressurized water and other types of reactors can be fabricated. The alloy consists of 3 to 25% niobium. 1 to 30% zirconium, and the balance uranium. The total weight of niobium and zirconium not exceeding 40%. The alloy should be in the gamma phase and clad with a zirconium-base alloy containing 0.1 to 2.5% tin and 0.1 to 2% of at least one of the elements iron, niobium, or chromium. and having a thickness ? 0.009 in. A method for producing and fabricating the fuel alloy is presented. A clad fuel alloy made in this way given only a 1 to 2 vol. ncrease it 0.45% burn-up and 385 deg C in a reactor, as compared with 8 to 10 vol. % increases for U-Nb alloys. Out-of-pile corrosion tests showed that this alloy has superior resistance compared with U-Nb alloys. (D.L.C.)
