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.

Inelastic scattering of 25.7-MeV neutrons to unresolved final states with excitation energies up to ∼13 MeV were measured for monoisotopic samples of 51V, 56Fe, 65Cu, 93Nb, and 209Bi. Neutrons were produced via T(d,n)4 He reaction in a gas cell that provides a background-free source spectrum above En = 12 MeV. Time-of-flight spectra were taken at several angles between 25 and 145 deg using the beam-swinger spectrometer. The technique of dynamic biasing proved valuable in providing maximum detector efficiency and low background throughout the broad range of neutron energies. Data were converted to energy spectra, corrected for detector efficiency, averaged over 1-MeV bins, and corrected for sample attenuation and multiple scattering.
