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.

Optical model parameters are recommended for the analysis of neutron cross sections in the atomic number range 24 to 73 and 4- to 20-MeV energy range. Using the real well potential V and real well radius coefficient R in the combination VR2, unique energy-independent fitting parameters are obtained regardless of the initial estimates. Neutron data for iron up to 100 MeV are analyzed using uniquely determined energy-dependent parameters.
