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 model is developed which gives the radius and temperature as a function of time for the fireball which forms following the release of a large amount of x-ray energy in the atmosphere. The presence of the ground is accounted for in the case of a near surface release of energy. Typical numerical results are given.
