![[terrestrial-usa-logo.png|300]] Company website: https://www.terrestrialenergy.com/ ### Introduction Terrestrial Energy Inc. is a Canadian nuclear technology company developing advanced Generation IV small modular reactors to provide low-carbon, reliable energy for industrial applications. Founded in 2013 by a team led by Simon Irish (CEO) and Dr. David LeBlanc (CTO), drawing on expertise in molten salt reactor designs, the company originated from efforts to commercialize innovative nuclear solutions for global decarbonization. Headquartered in Oakville, Ontario, Canada, with a U.S. subsidiary in Charlotte, North Carolina, Terrestrial Energy's mission is to transform energy markets by delivering cost-competitive, zero-emissions heat and power through its Integral Molten Salt Reactor (IMSR) technology, emphasizing safety, scalability, and economic viability. Key focus areas include deploying IMSR plants for cogeneration of electricity and high-temperature process heat, targeting heavy industries like petrochemicals, hydrogen production, desalination, and data centers. The company has advanced through regulatory milestones, including completing Phase 2 of the Canadian Nuclear Safety Commission's Vendor Design Review in 2022, and is pursuing commercialization amid growing demand for baseload clean energy, with plans for first deployments in the early 2030s. ### Key Products and Technology - **Integral Molten Salt Reactor (IMSR)**: A Generation IV small modular reactor using molten fluoride salt as both fuel and coolant, with uranium dissolved in the liquid salt; fully integrated design where all primary components are sealed within a compact vessel for enhanced safety and simplified operations. - **Power Output and Scalability**: Each IMSR core module produces 195 megawatts electric (MWe) or 390 megawatts thermal (MWth), with plants configurable from one to multiple modules for outputs up to gigawatt scale; 24-year operational cycle with online refueling for high availability. - **Fuel and Efficiency**: Utilizes low-enriched uranium (LEU) fuel in liquid form, enabling efficient fission product removal and waste minimization; achieves high thermal efficiency (up to 44%) due to operating temperatures around 700°C, far exceeding traditional light-water reactors; supports fuel recycling for closed cycles. - **Safety and Design Features**: Inherently safe with passive shutdown capabilities—salt freezes to contain radioactivity in accidents, no meltdown risk, low-pressure operation eliminates explosion hazards; walk-away safe without active intervention; resilient to external events, with reduced emergency planning zones; factory-fabricated modules for rapid deployment and cost savings. - **Applications**: Provides baseload electricity and industrial process heat for hydrogen/ammonia production, desalination (up to 100 million gallons daily per plant), petrochemical refining, and data center powering; integrates with renewables for hybrid systems; targeted for on-site deployment at industrial facilities to displace fossil fuels. ### Team and Leadership - **Simon Irish, CEO**: Founder and leader overseeing strategy, commercialization, and regulatory efforts; background in finance and energy investment, with prior roles at UBS and Scotia Capital; drives IMSR deployment for global markets.
