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.

The thermal neutron sensitivities of 231Rh self-powered neutron detectors were measured in a 1-MW(thermal) pool-type reactor. Measured relative sensitivities are statistically compared against calculated relative sensitivities. The latter are derived from a formula for the ratio of the lateral surface area of the rhodium emitter of a given detector to the lateral surface area of the rhodium emitter of a reference detector. Least-squares linear regression analysis of relative sensitivity versus surface area shows that the calculational method yields the same calibration results as the measured method with a high degree of accuracy.
