DOE fast tracks test reactor projects: What to know
The Department of Energy today named 10 companies that want to get a test reactor critical within the next year using the DOE’s offer to authorize test reactors outside of national laboratories. As first outlined in one of the four executive orders on nuclear energy released by President Trump on May 23 and in the request for applications for the Reactor Pilot Program released June 18, the companies must use their own money and sites—and DOE authorization—to get reactors operating. What they won’t need is a Nuclear Regulatory Commission license.

A contact device of a new type - a sulfonic cation resin membrane (Nafio type) contact device for separating isotopes of hydrogen in the water-hydrogen system is represented. Its main feature is space separation of hydrogen and liquid water flows that allows using non-hydrophobic catalysts for realizing the process. Results of research on the isotope exchange efficiency carried out for model protium-deuterium system have been represented. Mass exchange efficiency dependencies on temperature (T = 333-413 K), pressure (P = 0.1-0.4 MPa), the hydrogen flow rate (GH2 = 20-120 NL/h) have been investigated for both hydrophobic and hydrophilic catalysts. High efficiency of membrane contact devices is noted in carrying out the chemical isotope exchange between hydrogen and water in the given range of conditions.
