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 method is described where reactor cell flux and the disadvantage factor are calculated by using diffusion theory in the moderator and integral transport in the fuel. The method is efficient (noniterative) and provides results that agree well with Monte Carlo, P5, and ABH results.
