DOE fast tracks test reactor projects: What to know
The Department of Energy today unveiled 10 companies racing to bring test reactors online by next year to meet Trump's deadline of next Independance Day, leveraging a new DOE pathway that allows reactor authorization outside national labs. 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.

If a small (multimicrogram) 252Cf neutron source is used for neutron capture-gamma-ray analysis, a Ge(Li) detector must be placed relatively close to the source to obtain a reasonable counting rate. Thus, the encapsulation, moderating, shielding, and perhaps detector materials all become potential gamma-ray sources which cause spectral interference. An interference parameter for a number of elements generally used in source and detector construction is presented. Using this parameter, construction materials can be chosen to minimize the spectral interference. For minimum interference as well as fabrication and durability, zirconium, niobium, or tantalum alloys are among the better materials for source encapsulation or detector hardware.
