    In 2004, we developed the first unit of our novel oxygen isotope separation process by cryogenic oxygen distillation to overcome these issues. To meet the needs of the market, we built a second unit in 2013 and a third in 2016. We are now operating three commercially viable separation units with a total capacity of 600 kg of Water-18 O per year.

    AbstractThe first generation of a hydrogen isotope separation process called the thermal cycling absorption process (TCAP) has been in service for tritium separation at the Savannah River Site since 1994. To prepare for replacement, a next-generation TCAP process has been developed. This new process simplifies the column design and reduces the equipment requirements of the thermal cycling …

  • Electromagnetic Isotope Separation Uranium Enrichment

    Isotope - Isotope - Isotope separation and enrichment: Most elements are found as mixtures of several isotopes. For certain applications in industry, medicine, and science, samples enriched in one particular isotope are needed. Many methods have therefore been developed to separate the isotopes of an element from one another.

  • Isotope separation - WikiMili, The Best Wikipedia Reader

    Isotope separation by ion exchange has been applied to many elements, as is seen in Table 1.Obviously, mainly elements that have at least two naturally occurring isotopes have been studied, although in a few cases radioactive isotopes (e.g., for sodium: 22 Na and 24 Na) have been included in the studies. Most of the results are summarized in Table 2, with more detailed description being ...

    Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is various. The largest variety is used in research (e.g. in chemistry where atoms of "marker" nuclide are used to figure out reaction mechanisms).
