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.

The slowing-down spectra in several natural-uranium heavy-water reactor cores and in a U235 light-water reactor have been intercompared using activation techniques. The main features of the spectra agree with multigroup diffusion theory calculations but there are additional effects not included in the theory which can be correlated with uranium resonances.
