The deadline arrives: Checking in on the Reactor Pilot Program
On May 23, 2025, President Trump signed Executive Order 14301, “Reforming Nuclear Reactor Testing at the DOE,” which instructed the Department of Energy to create a Reactor Pilot Program (RPP)—a new system in which companies could pursue DOE authorization to build and test their first-of-a-kind nuclear technologies. EO 14301 set an ambitious goal for that program: three reactors achieving criticality by July 4, 2026.

A new spinning sample method has been used to measure the energies of beryllium-filtered neutrons scattered at 90° to the beam by samples of water, ethyl alcohol, n-amyl alcohol, benzene, paraffin, and zirconium hydride. The energy distributions from all samples show that an appreciable number of scattered neutrons gain energy. The zirconium hydride and water were measured to compare the spinning sample method with other methods of measuring inelastic scattering. The hydrogenous liquids were investigated to see if the scattering data could be correlated with known molecular properties and with proposed scattering theories.
