b'2026 and beyondMARVEL and PELE Microreactors INL has become a hub for the development of new microreactor designs. First on deck is the Microreactor Applications Research Validation and Evaluation project, or MARVEL, a sodium-potassium-cooled microreactor that will generate 85 kilowatts of thermal energy. It will be installed in the TREAT facility, with plans for it to go into operation in 2026. Concurrently, INL is the U.S. Department of Defenses lead laboratory for the Project Pele mobile microreactor project. Pele, an inherently safe mobile nuclear reactor that will generate 1 to 5 megawatts of electrical power, will operate for more than three years using TRISO fuel.79'
