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.
2022 ANS Annual Meeting
Jaime Marian is a professor in the Department of Materials Science & Engineering at UCLA. His group focuses on understanding materials evolution under extreme conditions using multiscale computational modeling, and developing efficient computational techniques, taking advantage of large-scale parallel computing capabilities. Specific areas of interest are microstructural evolution and mechanical property degradation in fusion materials, simulations of plastic deformation in alloys, simulations of thermodynamics and phase transformations in functional materials, strength in nanostructured crystals, and simulations of irradiation damage. He received his PhD in Nuclear Engineering from the Polytechnic University of Madrid, Spain, followed by a Postdoctoral Fellowship at the California Institute of Technology, and a staff scientist position at Lawrence Livermore National Laboratory. He has been the recipient of the DOE Early Career Award and is the author of over 100 publications in the areas of irradiation damage in materials, plasticity, deformation, mechanics, and numerical methods.
