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 of the energy spectra of delayed neutrons for the isotope-separated, fission product precursors 93-97Rb and 143-145Cs, over the energy region from ∼10 to ∼1300 keV, are reported. These data were obtained at the TRISTAN ISOL facility using gas-filled proton-recoil proportional counters. The data for each of the rubidium and cesium isotopes show good qualitative agreement with the existing 3He ionization chamber data at energies above ∼200 keV. In addition, they provide definitive spectral information down to ∼10 keV. Of particular note is the observation of line structure below ∼200 keV with energy resolution much better than that obtained using 3He ionization chambers.
