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.

An alternative method of thorium utilization in light water reactors (LWRs) is proposed. The main idea of the proposed concept is to apply a different fuel management scheme for the neutron-producing part of the core, the uranium seed, and for the neutron-absorbing part of the core, the thorium blanket. An example of the specific design based on this concept was analyzed, and preliminary evaluation indicated the potential of significant savings in uranium consumption. The fuel cycle of the proposed concept includes reprocessing and re-fabrication of uranium fuel only, without separation of plutonium and 233U isotopes. Such a fuel cycle offers higher proliferation resistance compared with the LWR recycle mode of operation or the light water breeder reactor fuel cycle. Finally, the feasibility of the reactor design based on the proposed concept may be established after detailed thermal-hydraulic analysis and study of the irradiation behavior of the thorium-based fuel.
