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.

A simple model is used to analyze the systems for feedback stabilization of the resistive wall mode (RWM) in proposed burning plasma experiments. In ITER, the presence of several conducting structures close to the control coils, but far from the plasma, leads to a slow feedback response time compared to the time scale of the RWM growth. In FIRE, the copper shell passive stabilizer sets a relatively long time scale for the RWM growth; therefore, the effects of higher resistivity structures close to the coils and far from the plasma are nearly negligible. RWM feedback control should be able to raise the stable N up to near the ideal-wall limit in FIRE with moderate requirements on the feedback electronics bandwidth.
