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.

Measurements of independent fission product yields from thermal-neutron fission of 235U, 239Pu, 233U, and 241Pu have been compared with expected yields from a semiempirical analytical model. A general correlation between the experimental/theoretical ratio and the distance of the nuclide from Zp, the most probable charge in a fission product mass chain, has been constructed. This correlation can serve as a basis for assigning uncertainties to theoretical yield estimates.
