Terrestrial Energy Inc Dossier
Qualitative Analysis
Business overview
Terrestrial Energy Inc. (NASDAQ: IMSR) is a developer of Generation IV small modular nuclear power plants based on its proprietary Integral Molten Salt Reactor (IMSR) technology. The company's IMSR design is engineered as a cogeneration plant capable of producing both cost-competitive, zero-emission electricity (392 MWe) and high-temperature thermal energy (882 MWt at up to 585u0000C / 1,085u0000F) on a compact 17.3-acre footprint. This dual-output capability allows the IMSR to serve diverse, energy-intensive industrial applications beyond traditional power grids, including petrochemical synthesis, clean hydrogen production, and large-scale data centers. A key strategic advantage of the IMSR is its utilization of standard-assay low-enriched uranium (SALEU) fuel containing less than 5% U-235, bypassing the geopolitical and supply chain bottlenecks associated with High-Assay Low-Enriched Uranium (HALEU).

Strategic Initiatives
Growth programs, investments, and their expected impact
Securing site control and exclusive access to 77 acres at the Texas A&M-RELLIS campus to complete site characterization, environmental evaluations, and construct a commercial IMSR Plant.
Expected impact: Establishes one of the first commercial Generation IV reactor deployments on the ERCOT grid, providing a physical platform to accelerate commercial operations.
Two partnership projects with the U.S. Department of Energy (DOE) under the Advanced Reactor Pilot Program. TETRA focuses on the demonstration of a pilot reactor, and TEFLA focuses on demonstrating fuel salt production.
Expected impact: Accelerates IMSR Plant licensing and commercial fuel supply readiness, proving the viability of the technology.
A manufacturing and supply contract with Springfields Fuels Limited (a Westinghouse subsidiary) for the design and construction of an IMSR fuel pilot plant.
Expected impact: Secures a Western supply chain for Standard-Assay Low-Enriched Uranium (SALEU) fuel, avoiding geopolitical and supply chain risks associated with HALEU.
