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.

A redetermination of the age τ (= ⅙ 〈r2〉) for neutrons of indium-resonance energy (1.46 ev) from a point U235 fission source is reported. Foils were irradiated in a geometrically simple arrangement in the Penn State Reactor pool, and counted in a standard manner. The value obtained, τ = 27.3 ± 0.9 cm2, is in better agreement with current theory than those from previous measurements. The spatial distribution found here differs most markedly from those observed in previous experiments by having a larger slope in the region within a few centimeters of the source.
