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.

In various graphite piles, where one or two Ra-Be sources were producing a stationary neutron field, the neutron temperature was measured by activating an indium foil, sandwiched between two gold absorbers. The neutron temperature was found to be up to 70°C above the graphite temperature, which is explained by the incomplete thermal equilibrium.
