Title: Chemical, mass spectrometric, spectrochemical, nuclear, and radiochemical analysis of uranium hexafluoride

Analytical procedures, which are in routine use to determine conformance to uranium hexafluoride (UF/sub 6/) specifications in the Department of Energy gaseous diffusion plants or at other installations, are described in detail. Included are: subsampling of UF/sub 6/; gravimetric determination of uranium; titrimetric determination of uranium and of chlorine; preparation of high-purity U/sub 3/O/sub 8/; isotopic analysis by double-standard and by single-standard mass-spectrometer method; determination of hydrocarbons, chlorocarbons, and partially substituted halohydrocarbons; atomic absorption determination of antimony, ruthenium, and metallic impurities; spectrophotometric determination of bromine, silicon and phosphorus, titanium and vanadium, tungsten, thorium, and molybdenum; spectrographic determination of boron and silicon, ruthenium, thorium and rare earths; spectrographic determination of metallic impurities by carrier distillation; spectrographic determination of hafnium, molybdenum, niobium, tantalum, titanium, tungsten, vanadium, and zirconium after separation from UF/sub 6/ with BPHA and as cupferrides; impurity determination by spark-source mass spectrography; determination of boron-equivalent neutron cross section; determination of uranium-233 abundance by thermal ionization mass spectrometry; determination of uranium-232 by alpha spectrometry; determination of fission product activity by beta and gamma counting; determination of plutonium by ion exchange and alpha counting;determination of technetium-99 in UF/sub 6/; determination of gamma-energy emission rate from fission products in UF/sub 6/; determination ofmore » plutonium and neptunium by extraction and alpha counting; atomic absorption determination of chromium soluble and insoluble in UF/sub 6/.
