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.

Gamma-ray production cross sections were measured for (n, n′y) reactions in 56Fe, 58,60,62Ni, 93Nb, and 181Ta for neutron energies from threshold to 1.8 MeV. Neutron inelastic scattering level excitation functions were then obtained from the gamma-ray production cross sections by correcting for internal conversion and for cascading transitions. A 17-cm3 Ge(Li) spectrometer system was used to measure the gamma-ray spectra. The experimental results were compared with statistical model calculations using optical model transmission coefficients. Corrections for resonance interference and width fluctuations were also included in the computations. In general, the calculated results agreed with experiment to within the quoted error. Furthermore, the results for the deformed nucleus 181Ta indicated that a spherical optical model potential may be used successfully to obtain the level excitation functions for this nucleus.
