The Analysis of Unirradiated “Fissium” Alloy by Optical Emission Spectroscopy

Abstract

An optical emission spectrographic method has been developed for the quantitative determination of molybdenum, ruthenium, rhodium, palladium, and zirconium in normal uranium metal in the range of 2.5%, 2.0%, 0.30%, 0.20%, and 2.5%, respectively. The precision of the spectrographic method for molybdenum is ±1.0%, ruthenium ±18%, rhodium ±17%, palladium ±21%, and zirconium ± 2.2% of the amounts present The comparison of spectrographic and chemical results on 24 “fissium” alloy samples for molybdenum, ruthenium, rhodium, palladium, and zirconium shows a standard relative deviation from the chemical results of ±3.9%, ±4.3%, ±7.2%, ±6.6% and ±7.5%, respectively. These samples were chosen at random from ingots by using routine sampling procedures
