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 one-speed neutron transport equation with anisotropic scattering is investigated by the method of partial-range Legendre-polynomial analysis. It is found that appropriate conditions on the spatial moments can be specified by suitable integral operations of the partial-range polynomials. A numerical test suggests that such an analysis does possess potential merit for calculating some neutron transport parameters to a high degree of accuracy even in a low order approximation.
