Terrestrial Energy Inc. (NASDAQ: IMSR) ("Terrestrial Energy" or "the Company"), a developer of small modular nuclear power plants using its Generation IV reactor technology, today announced it has signed a manufacturing and supply contract with Springfields Fuels Limited, a subsidiary of Westinghouse Electric Company ("Westinghouse"), for the design and construction of an Integral Molten Salt Reactor (IMSR) fuel pilot plant. The agreement serves as a significant advancement of Terrestrial Energy's fuel supply chain capabilities in support of the Company's accelerating commercialization pathway, with construction set to begin in 2026.

The agreement, building on a contract signed in August 2023 for the planning and initial design of IMSR fuel supply, leverages established deconversion and fuel manufacturing infrastructure at Westinghouse's Springfields nuclear fuel manufacturing site in Preston, United Kingdom, to support Terrestrial Energy's IMSR deployment strategy. The expanded scope includes a wide range of commercial-scale fuel services, such as deconversion, fabrication, packaging and transportation. Upon completion of the pilot plant, the facility will be positioned to scale to commercial fuel production for a future fleet of IMSR Plants.
