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.

This paper discusses the model and results for the Peach Bottom 2 Turbine Trip Test 2 using Studsvik Scandpower's transient code SIMULATE-3K. All data pertaining to core, vessel, and scenario were taken from the NEA/OECD BWR benchmark specifications. Nuclear data were generated with Studsvik Scandpower's lattice code CASMO-4 and core analysis code SIMULATE-3. Comparisons to measured data, sensitivity to model options and data, as well as results from more limiting scenarios are presented. SIMULATE-3K captures well the pressure wave propagation, void collapse during the pressurization phase, and resulting power excursion.
