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 total neutron cross sections of samarium highly enriched in the 147Sm and 150Sm isotopes have been measured from 0.01 eV to 1.2 keV. Thermal neutron cross sections and resonance parameters were extracted, and the S-wave strength functions and capture resonance integrals were calculated. Corrections for paramagnetic and small angle scattering were applied to the thermal-neutron cross sections in order to obtain thermal absorption cross sections. The following results were obtained:
