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.

Japanese contributions to ITER engineering design activities are presented, together with an introduction of the objectives and design of the ITER, whose program has been carried out through international collaboration by the European Union, Japan, Russian Federation, and the United States. New technologies have been produced through the development, fabrication, and testing of scalable models in the fields of superconducting magnets, reactor structures with vacuum vessels, remote-maintenance machines, high-heat-flux plasma facing components, neutral beam injectors, high-power millimetre-wave generators, etc. As major contributions from Japan, development and testing results of a 13-T, 640-MJ, Nb3Sn pulsed magnet; an 18-deg sector of a vacuum vessel with a height of 15 m and a width of 9 m; CFC armor for a CuCrZr cooling tube that withstood 20 MW/m2; a 31 mA/cm2 negative ion beam source; a 1-MeV beam accelerator; and a 1-MW 170-GHz gyrotron are described.
