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.

Postirradiation electrical resistivity changes have been found to be a measure of the irradiation temperature. Molybdenum and tungsten rod specimens were irradiated in the Experimental Breeder Reactor II to a neutron fluence of 1.1E+26 n/m2 (En > 1 MeV) simultaneously at six different temperatures, ranging from 455 to 1050°C. The postirradiation isochronal resistivity measurements made on the specimens showed a close relationship between the initial resistivity recovery temperatures and the original temperatures determined from the melt wires and SiC monitors irradiated in the same capsules. Experimental results indicated the possibility of molybdenum and tungsten wires as irradiation temperature monitors (molybdenum up to 850°C and tungsten up to ∼1400°C).
