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 ratio of the fission cross sections of 239Pu to that of 235U has been measured at 30 keV and from 0.5 to 5.4 MeV. A value of 0.796 ± 0.020 has been obtained at 30 keV. None of the structure reported recently by Savin et al. could be found in the MeV range in the present measurements.
