DOE fast tracks test reactor projects: What to know
The Department of Energy today named 10 companies that want to get a test reactor critical within the next year using the DOE’s offer to authorize test reactors outside of national laboratories. 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.

Plasma can be studied and characterised by the analysis of its radiation1,2. Signals obtained by passive spectroscopy contain much information about temperature, density and flux of the main species and impurities3. The interpretation of measured line intensities requires the knowledge of atomic physics describing the specific radiation from the plasma. Tomographic methods are applied but they need symmetries for the calculation of local parameters. Additionally in magnetic confined plasmas the interpretation might be more difficult due to the Zeeman splitting.
