The determination of uranium in zirconium and Zircaloy in the range O.25to 20 ppm on a one gram sample basis. These limits can be varied by changing the size aliquot used for the final uranium determination. Samples are dissolved in hydrofluoric acid and water. Sulfuric acid is added, and the solutions are taken to dryness. The sulfates are dissolved in hot water and the solutions made 2.3 M in nitric acid and saturated in aluminum nitrate. Uranium is then extracted with diethyl ether. After removing the ether, an aliquot is fused with a button of sodium fluoride. The fluorescence produced by the uranium is measured with a photoelectric fluorometer. (auth)
