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.

We consider all 25 projectile-target combinations of the particles p, d, t, 3He, and α. We obtained nuclear plus interference elastic cross sections for such interactions by subtracting Coulomb contributions from experimental data. We present evaluated graphs of the following resulting quantities, integrated over center-of-mass scattering cosine: reaction rate, average fractional energy loss per collision, average fractional energy loss per unit path length, and average laboratory scattering cosine. This information can be used to correct energy loss rates due to Coulomb scattering, or in more exact transport calculations that account for large-angle nuclear scattering.
