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.

Numerical calculations performed on the ORACLE have made possible exact inclusion of the effect of Doppler broadening of resonance lines in the calculation of resonance absorption integrals. The effective resonance integrals of U238 and Th232 have been calculated as functions of the scattering cross section per absorbing nucleus for 0° and 300°K. Agreement of the calculated (300°K) and experimental resonance integrals is excellent for U238 and good for Th232, except in the case of pure ThO2 where a discrepancy is noted.
