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.

An improvement of a single-bubble model in sodium boiling is discussed. A bubble-breaking effect is inductively inferred from an analysis of experimental data and is related to the local geometric enlargement of the flow channel. A simple bubble-breaking mechanism is consistently introduced in the basic equation, thus obtaining a more satisfying agreement between measured and calculated quantities.
