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.

Differential cross sections have been measured at the University of Lowell for the ground and first two excited states of 232Th via the neutron time-of-flight technique. The following results are presented for neutron scattering cross sections: (a) excitation functions of 232Th in the incident energy range from 185 to 2400 keV for the 0+ ground state and the 2+, 49-keV state, and in the 480-to 2400-keV range for the 4+, 162-keV state; (b) angular distributions for the 0+ and 2+ states at 185 keV and for the 0+, 2+, and 4+ states at 550 keV. Level cross sections were obtained using these and previously measured angular distributions. The University of Lowell 5.5-MV pulsed Van de Graaff accelerator with a Mobley bunching system was employed to generate neutrons via the 7Li(p, n)7Be reaction. Metallic lithium targets were 8 to 10 keV thick, enabling an overall resolution of 15 to 20 keV to be maintained throughout the measurements. The scatterer was disk shaped. Details of data reduction and finite scatterer size effects are discussed. The experimental results are compared with theoretical results and ENDF/B-V.
