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.

Fatigue tests were conducted in sodium to investigate the influence of an elevated temperature sodium environment on the low cycle fatigue behavior of Types 304 and 316 stainless steel The fatigue tests were conducted at 550°C in sodium of controlled purity, namely, 1 ppm oxygen and 0.3 ppm carbon, at a strain rate of 4 × 10−3s−1. The fatigue life of annealed Type 316 stainless steel was substantially greater when tested in sodium than when tested in air, whereas the test environment had little influence on the fatigue life of Type 304 stainless steel. The effects of long-term sodium preexposure were also investigated. An 18-Ms (5000-h) preexposure to sodium produced little effect on the fatigue life of Type 316 stainless steel tested in sodium. However, a similar sodium exposure had a significant effect on the fatigue behavior of Type 304 stainless steel.
