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.

Analyses of property changes during reirradiations and anneals show that the technique of alternate reirradiations and anneals can be used consistently to remove radiation damage from graphite. Laboratory experiments, monitoring studies and reactor-height measurements all correlate favorably. It is shown that the recovery for a reirradiation and annealing cycle is independent of irradiation temperature between 30 C and 200 C and total damage over wide ranges. The reciprocal of the recovery per cycle is a linear function of the exposure between anneals with a slope that is determined by the anneal temperature.
