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.

Thermal-neutron fission cross sections and fission resonance integrals were measured for 249Cf and five isotopes of curium with both dual fission chambers and plastic fission track recorders. Measurements were made in the thermal column and core of the SP research reactor. Cross sections were determined through direct comparison with the appropriate 235U fission cross sections, i.e., (effective) = 561.5 b and Iƒ = 268 b. For the resonance integral measurements, the low-energy cutoff has been adjusted to 0.625 eV. The measured cross sections are:
