Terrestrial Energy Executes DOE Agreement for Project TEFLA Under Fuel Line Pilot Program Terrestrial Energy (NASDAQ: IMSR) executed an Other Transaction Authority (OTA) agreement with the U.S. Department of Energy to build and operate Project TEFLA, a pilot plant to demonstrate IMSR Fuel Salt production using standard-assay low-enriched uranium (SALEU <5% U235) feedstock. TEFLA is part of the DOE Fuel Line Pilot Program under Executive Order 14301 and will support the Company’s Project TETRA test reactor. DOE will review TEFLA design for safe handling and expedite authorization, enabling faster development of IMSR fuel supply and commercial reactor deployment.Terrestrial Energy says its commercial IMSR plant design produces 822 MWth (390 MWe) and avoids HALEU reliance.
