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 stability analysis for coarse-mesh rebalance (CMR) is developed and tested. The analysis is based on linearizing the CMR algorithm for a special class of problems and using a Fourier analysis to study the stability of the linearized algorithm. Numerical experimentation shows that the original (nonlinear) and linearized CMR methods have basically the same convergence properties and that these properties are accurately predicted by the Fourier analysis.
