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.

A technique to obtain the energy group-to-group transfer cross sections for neutron elastic scattering is presented. This method, which avoids the traditional Legendre polynomial expansions, can be used directly in a discrete ordinates formulation of the transport equation to give accurate numerical results for those situations in which the group-to-group transfer is highly anisotropic.
