Terrestrial Energy Inc. is a nuclear technology company developing Generation IV small modular reactors through its proprietary Integral Molten Salt Reactor (IMSR) technology. The IMSR plant delivers reliable, emission-free, high-temperature heat and electricity, operating at 600°C with 50% greater thermal efficiency than conventional light-water reactors, using low-enriched uranium in a graphite-moderated, fluoride molten salt system. This design features a replaceable reactor core for simplified maintenance and inherently safe operation via natural convection heat dissipation, producing 40% less nuclear waste while enabling dual-use applications in cogeneration plants with 822 MWth / 390 MWe capacity. Targeting sectors like data centers, industrial processes, grid power, and low-carbon fuels production, it supports decarbonization with flexible, cost-competitive energy solutions and a CAPEX-light model spanning engineering, component supply, and fuel services over 50+ year lifecycles. Partnerships with Westinghouse, Schneider Electric, U.S. Department of Energy, and others bolster its progress toward commercialization in the early 2030s. Founded in 2013 and headquartered in Oakville, Canada, Terrestrial Energy Inc. advances regulatory reviews and project deployments to transform global energy markets.
