MARVEL, under development at Idaho National Laboratory (INL), is a 85-kWth/20-kWe sodium-potassium-cooled microreactor that will help researchers explore advanced reactor applications, including microgrid integration, remote monitoring, and autonomous control technologies. TRIGA International recently began fabricating fuel for MARVEL, with the first shipment expected by spring 2025. Fuel loading is planned for 2026, and the reactor is projected to be operational by 2027. Source: DOE
