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 variation of the postirradiation creep-rupture properties with irradiation temperature has been evaluated for air- and vacuum-melted Hastelloy-N. The air-melted material was high in silicon and formed a stable carbide of the M6C type. The properties of this material were not dependent upon the irradiation temperature over the range studied. The vacuum-melted alloys formed a M2C-type carbide whose size and morphology depended markedly upon the irradiation temperature. When the carbides were finely dispersed by irradiation at about 650°C, the postirradiation properties were equivalent to those of the air-melted material. Irradiation at about 760°C resulted in coarser dispersions of the M2C carbide and inferior postirradiation properties.
