[en] The creation of the US Enrichment Corporation as a government commercial enterprise has brought with it flexibility to explore new and different ways to serve customers, to manage the business better and to develop alternative supply options. The availability and reliability of the uranium isotope separation plants has improved and overall efficiency has been increased. Plans for the future include a commitment to the deployment of atomic vapour laser isotope separation. USEC still operates within many of the constraints of government but is due to be privatised in 1996. (UK)

[en] The isotopes of a gas are separated by using a circularly polarized laser to excite a lower energy level to higher split intermediate energy levels, a second laser pulse of the same circular polarization is applied to said energized gas at a time π/Δω where πΔ is the frequency splitting of the intermediate levels, to excite the excited intermediate levels to a higher energy level where an ionizing field ionizes the atoms or molecules in the higher level so that they may be separated from the unionized atoms or molecules of the other isotope

[en] An on-line isotope separator facility has been built at the Chalk River MP tandem Van de Graaff accelerator. The main design characteristics are high resolution (M/ΔM > 7000) and a current capability of 20 mA for masses between 1 and 300. The system incorporates an inhomogeneous 135⁰ magnet of high dispersion, D = 2250 mm. A novel feature, two pairs of corrective coils acting independently on the linear and quadratic magnetic field terms, has proven to be extremely advantageous for fine tuning of the magnetic dipole. The separator has been tested off-line, and is now frequently used on-line, with overall efficiencies reaching tens of per cent for light elements such as Na, Cl, K, Mn, Zn and Br. (orig.)

[en] The development of the jet nozzle process for uranium enrichment is summarised, with the technical advances attained, and problems still to be overcome. The cutbacks in Brazil's nuclear programme are also outlined. (UK)

[en] Isotope separation applications are briefly reported. (U.S.)

[en] The major characteristics of the AVLIS uranium enrichment process and its impact on the commercial approach to enrichment are discussed

[en] This patent describes an isotopic separation system for continuously separating the isotopes present in a sample containing a mixture of isotopes of a chemical element in ionic form. It comprises rotatable annulus means, an isotope-containing sample feed source, an eluant source, a pair of annular electrode means, and drain assembly means

[en] China Institute of Atomic Energy (CIAE) has accomplished state science and technology support plan topic (research and development of high purity organic reagent corn unit using for research and commonness key technology). "5"4Fe, "6"5Cu, "6"4Zn, "6"7Zn, "2"0"7Pb and "8"5Rb, "8"7Rb were separated using electromagnetic method. And the abundances of them archived: 90%, 99.6%, 96%, 81%, 90%, 99% and 98%. The level of these isotopes preparation has reached overseas product standard. Some of them have been used in the production of science research and rubidium clock production for satellite navigation. It established technology base for material domestic production of special stable isotopes in China. (authors)
