Its intended customers are plant developers and owner-operators, including utilities and industrial users in data centers, mining, chemical and petrochemical production, manufacturing, and coal-plant repowering.

It expects recurring core-unit and fuel supply over each plant’s designed 56-year operating life. The IMSR uses low-enriched uranium and is designed to provide up to 390 MW of net electricity or heat at 585°C. Terrestrial Energy has one principal business focused on developing and commercializing the IMSR Plant; it reports no operating segments in the supplied business description. It had approximately 80 employees in 2025. The company began in 2013 as Terrestrial Energy Development Inc.; following a 2025 business combination with HCM II Acquisition Corp., it became a holding company.
