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.

Radiation induced change in electrical conductivity of proton conductive ceramics (Yb-doped SrCeO3) have been investigated under 14 MeV fast neutrons in air at temperatures of 293 and 373 K. It was found that the electrical conductivity under neutron irradiation at 293 and 373 K gradually decreased with increased neutron fluence reaching a constant for neutron fluences above 2.0 × 1018 and 1.0 × 1017 n/m2, respectively. The decrease of the electrical conductivity may be associated with annihilation of sub-bands due to Ce4+ to Ce3+ conversion.
