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 convergence of the iterative procedure for solving the slowing down equation is examined. It is found that the rate of convergence of the iterative procedure depends on the ratio of the resonance scattering and absorption cross sections, being rapid if the resonance is predominantly absorbing. The method of Goldstein and Cohen for treating intermediate resonances is carried to the third approximation, and numerical results are obtained for the 192-eV resonance of 238U in a 1:1 mixture with hydrogen.
