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.
We develop software for accurately, efficiently, and easily predicting radiation fields. Our Attila® and Attila4MCTM products are used worldwide for shielding, radiological protection, and a myriad of other scenarios where radiation effects play an important role in product or system performance, safety, or reliability. Our mission focuses around delivering state-of-the-art software leveraging both Monte Carlo and deterministic methods, and combining with robust CAD integration, to help organizations efficiently integrate radiation transport simulations into their design cycle.
