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 spectra in uranium depleted in the 235U isotope are analyzed with ENDF/B-III data, accounting for high-order anisotropic scattering. Two principal conclusions are made. First, changes made to inelastic scattering data relative to earlier ENDF/B files are not effective in reducing discrepancies between calculated and measured spectra. Second, changes made to unresolved capture data lead to significant improvement in the relation between calculation and experiment.
