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 simple numerical solution algorithm is used to model rigid body impacts on liquid surfaces. Computed fluid impact loads on right circular cylinders are in excellent agreement with experimental data. Several calculations are performed with varying fluid sheet thicknesses, impact velocities, and cylinder diameters. These calculations verify the scaling ability of the theoretical model and provide insight into how loading histories vary with the configuration of the impacting fluid.
