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.

An iterative method has been developed for the solution of neutron-transport problems. The method is formulated within the framework of a spherical-harmonics method. The method is developed first for one-group problems, then for more general velocity-dependent problems. The method is illustrated by application to the Milne problem for the one-group case and also to a velocity-dependent variation of the Milne problem. Good accuracy is obtained for both cases.
