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.

In the GAMMA 10 tandem mirror, neutral hydrogen densities in the central-cell and anchor-cell have been estimated by measuring spatial profiles of H line-emission with absolutely calibrated H line-emission detectors. Absolute measurements of H line-emission enable us to evaluate the neutral density based on the collisional-radiative model. Recently, single channel H line-emission detectors were installed in plug/barrier cells, where the axial confining potentials are produced by electron cyclotron resonance heating. We studied the neutral particle behavior in the plug/barrier cells for the first time using the newly installed H line-emission detectors. Moreover we have designed and installed a multi-channel H line-emission detector system to study the neutral hydrogen behavior in the plug/barrier cell.
