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.

Total attenuation cross sections for several sugars are measured for 661.6-, 1173-, and 1332.5-keV photons in a narrow beam geometry setup, by using a hyperpure germanium detector. These values are compared with the values calculated by using the mixture rule based on Hubbell’s data for the individual elements and are found to be in good agreement. Based on the measured values for different sugars, a set of mean mass attenuation coefficients for sugars is given for the energies of interest.
