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 neutron capture cross section of stable 93Nb was measured by time-of-flight methodology at the Oak Ridge Linear Electron Accelerator. Individual resonances were parameterized to 7.4 keV with energy resolution ≤0.14% full-width-at-half-maximum. The average cross section was deduced from 3 to 700 keV with an accuracy estimated at 3 to 5% SD. The average data to 100 keV are well fitted by strength functions, but the fluctuations about the fit are not consistent with an energy-independent level density proportional to 2J + 1 beyond 20 keV.
