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.

Gamma rays from the fission product nuclides 140Ba and 140La are frequently used for monitoring fission rates in neutron activation detectors consisting of fissionable materials. Systematic errors that can occur when the 1596-keV line of 140La is taken as the monitor line can be avoided by using the 537-keV line of 140Ba. The gamma-ray emission probabilities per decay of 140Ba and 140La were redetermined for the more abundant lines with a relative uncertainty of about ±1% at the 68% confidence level.
