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.

During injection, inertial fusion energy (IFE) direct drive (DD) targets are subject to heating from energy exchange with the background gas and radiation from the wall. This heat deposition could lead to deuterium-tritium (DT) phase change and target deformation violating the target physics symmetry requirements. This paper assesses the thermal behavior of the target under such conditions and explores possible ways of extending the target lifetime.
