Terrestrial Energy Executes DOE Agreement for Project TETRA Under Advanced Reactor Pilot Program

Core Viewpoint - Terrestrial Energy has signed an Other Transaction Authority (OTA) agreement with the U.S. Department of Energy (DOE) to advance Project TETRA, a pilot reactor initiative that will facilitate the development of Integral Molten Salt Reactor (IMSR) technology, positioning the company for rapid commercialization of IMSR plants [1][2][3] Group 1: Project TETRA and OTA Agreement - The OTA agreement allows for the construction and operation of a pilot reactor under the DOE's Advanced Reactor Pilot Program, enabling a streamlined collaboration for design review and authorization [1][2] - The TETRA reactor will utilize low-enriched UF₄-based fuel (SALEU) with less than five percent U-235, which supports the company's goal of moving quickly from design to operation [2][3] - This agreement provides a flexible framework for innovation in advanced reactor technology, allowing Terrestrial Energy to operate outside traditional federal contracting constraints [2][3] Group 2: IMSR Technology and Market Position - The commercial IMSR plant is designed to produce 822 MWth (390 MWe) of low-cost clean energy, suitable for electricity generation and industrial heat applications [3] - The high-temperature molten salt fuel design enhances efficiency and supports various industrial applications, including data centers and manufacturing [3][5] - Terrestrial Energy's approach eliminates reliance on high assay low-enriched (HALEU) fuel, thereby improving supply security and scalability with existing U.S. manufacturing infrastructure [3][5] Group 3: Regulatory Environment and Future Engagement - The Advanced Reactor Pilot Program, established under Executive Order 14301, allows the DOE to authorize privately built reactors, facilitating a pathway to regulatory authorization for commercial operations [4] - Terrestrial Energy's selection for the DOE Fuel Line Pilot Program in September 2025 highlights its active engagement with DOE initiatives aimed at expediting the commercialization of small modular nuclear plants [4][6] - The company is focused on building, licensing, and commissioning the first IMSR plants in the early 2030s, indicating a commitment to advancing nuclear energy technology [6]
