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 Eulerian finite difference technique is presented for solving the conservation equations for homogeneous compressible fluids. The method uses a Newton-Raphson-type relaxation scheme formed to enable the computation of sharp density gradients at all flow speeds. A derivation of the numerical algorithm and two example problems are presented.
