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.

Energy-averaged total neutron cross sections of elemental vanadium were measured from ∼1.0 to 5.5 MeV. Differential elastic and inelastic neutron scattering cross sections were measured from 1.8 to 4.0 MeV. Neutrons corresponding to the excitation of states in vanadium at 321 ± 10, 938 ± 15, 1603 ± 19, 1811 ± 21, 2409 ± 27, ∼2500, 2706 ± 30, and 2773 ± 30 keV were observed. These experimental results were used to deduce an energy-averaged nuclear model suitable for extrapolating the measured values and calculating unmeasured cross sections for applied use.
