DOE fast tracks test reactor projects: What to know
The Department of Energy today unveiled 10 companies racing to bring test reactors online by next year to meet Trump's deadline of next Independance Day, leveraging a new DOE pathway that allows reactor authorization outside national labs. 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.

The combined neutronic heating from gamma and neutron attenuation was measured in stainless steel and graphite samples irradiated in the High Flux Isotope Reactor (HFIR). Measurements were made at intervals during a reactor fuel cycle and at various elevations with respect to the reactor core. Peak energy depositions measured were 13.6 W/g in graphite and 16.6 W/g in stainless steel. The experiments illustrated the importance of considering local environment, especially near by radiation sources and sinks, as well as the geometry of the material, when estimating energy deposition rates.
