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.

Measurements have been made of the fast neutron cross sections for the production of N16 and N17 in the uranium rod cooling water of the NRX reactor by the reactions O16(np)N16 and O17(np)N17. The N16 and N17 were detected by their gamma and fast neutron activities, respectively, in a continuously flowing sample of the effluent water from a uranium rod. The cross sections (fission neutron spectrum) for the reactions O16(np)N16 and O17(np)N17 are 1.85 ± 0.15×10-2 millibarns and 9.3 ± 0.9×10-3 millibarns, respectively.
