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 basic neutron physics investigations and the conceptual design of a cylindrical fast subcritical facility for investigating the properties of fast reactor blankets have been completed. The Department of Nuclear Engineering at Purdue University plans to construct this facility to enable students to carry out studies in fast reactor blankets and reflectors. Fast neutron flux spectra in this facility can be made very similar to the spectra anticipated in the blanket of either a typical large liquid-metal or gas-cooled fast breeder reactor. Fast neutron spectra, spatial flux distributions, plutonium production rates, neutron transmission, and other physics parameters of typical fast reactor blanket designs can be investigated with this facility. The results can be used to refine the analysis and to improve the designs of blankets and structures outside the blankets in future fast breeder reactors.
