Samples are dissolved in hydrofluoric and nitric acids. The solutions are saturated with aluminum nitrate, and uranium is extracted with diethyl ether. The uranium is stripped from the ether layer into water, and an aliquot of this solution is fused with a mixture of sodium and lithium fluorides. The fluorescence produced by the uranium is measured with a photoelectric fluorometer. The method covers the determination of uranium in zirconium and Zircaloy in the range of 0.3 to 5 ppm on a one-gram sample basis. These limits can be varied by changing the size aliquot used for the final uranium determination. (auth)
