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.

Fast ignition is a concept that is being actively investigated in the HED community. The fast ignition targets described here are highly precise targets composed of a small glow discharge polymer (GDP) shell (~860 m diameter) mounted on a gold hyperboloid tipped cone. The process of creating these targets is composed of several steps. The first step consists of machining a copper cone that is then plated with a layer of gold approximately 120 m thick. Next, a hole is machined in a hollow GDP shell that will later be mounted on the gold gone. After the hole of this shell has been measured, the coated cone is machined to shape and to include a shelf so that the shell will sit at the desired location in relation to the tip of the cone. Finally, the copper mandrel is etched away from the gold and the target is assembled with the shell glued into place. At every step of this process, parts must be made and kept within tight specifications to meet the target requirements, not the least of which is that after assembly the shell center must be a specified distance from the gold cone tip with a tolerance of less than 10 m.
