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 linear discontinuous Galerkin treatment is developed for the continuous slowing down operator. Multigroup Legendre coefficients are derived that allow this treatment to be implemented in standard Sn codes, A synthetic acceleration scheme is developed to accelerate the outer iterations required by this treatment. A computational comparison between the diamond difference treatment and the linear discontinuous treatment is given.
