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 tentative method for the calculation of the void volume fraction at zero quality in case of constant heat input along the channel is presented. By assuming a constant volumetric condensation density, proportional to the squared flow velocity, the void volume fraction at zero quality can be predicted. Comparing the calculated void volumes with actual measurements for water, the error in the void calculation is less than ±25%.
