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.

Neutron total cross sections of natural chromium were measured from 1.0 to 4.5 MeV with intermediate energy resolution at intervals of 50 keV Elastic and inelastic differential scattering cross sections were determined over the energy and angular range of 1.5 to 4.0 MeV and 20 to 160 deg, respectively. Scattered neutron groups were observed corresponding to average inelastic excitation energies of 1.433 ± 0.009, 2.377 ± 0.008, 2.665 ± 0.005, 2.778 ± 0.007, and 2.970 ± 0.006 MeV. The experimental results were examined in terms of the spherical optical statistical model with additional consideration of the vibrational direct excitation of the 1.433 first-excited level
