“Extraordinary confluence of factors is driving a secular expansion in nuclear energy supply," Simon Irish said at Santander's 2026 AI Power Race Conference's "Power and AI Infrastructure Trends" panel, making the case for nuclear's role in powering AI. The panel brought together power development, infrastructure investing and advanced nuclear around one question: How does the U.S. build enough power, fast enough, for the AI era? Simon's case for why nuclear fits: - The nuclear supply response is taking shape in three ways: restarting existing plants, new conventional nuclear plant, and small modular reactor plants. - Clean firm SMRs can be co-located next to demand. That matters as transmission and pipeline congestion builds. - Capital and regulation are both moving impressively to support this expansion of nuclear supply at a scale the sector hasn't seen in half a century. - At Terrestrial Energy, we designed the IMSR Plant for high capital efficiency and swift fleet scale deployment focused on avoiding supply chain constraints using standard LEU fuel, leveraging existing supply chain infrastructure. Thank you to Santander for the invitation and a great conversation. #NuclearEnergy #AI #IMSR

Another milestone achieved for Terrestrial Energy's IMSR Plant regulatory program! We've submitted our Graphite Topical Report to the U.S. Nuclear Regulatory Commission, the second of at least three Topical Reports we expect to submit to the NRC this year. The submission supports the regulatory basis for qualifying graphite, a central component of the IMSR Core-unit, for use in commercial plant operations. Graphite qualification is the process that permits the NRC to recognize the licensing basis for IMSR graphite. Once approved, this becomes a permanent part of that basis, referenceable in future IMSR Plants regulatory applications avoiding continuous re-evaluation. This regulatory progress demonstrates further execution of the Company’s regulatory strategy, moving the IMSR Plant systematically closer to licensed commercial operation. → Full press release: businesswire.com/news/home/2…

As utilities turn to advanced nuclear to help meet unprecedented energy demand, not all reactor designs carry the same risk. Our VP of Business Development, Sarfraz Taj, breaks down with @POWERmagazine the three questions every utility should ask before investing: 1. How Capital-Efficient Is a Technology Over Its Full Lifetime? 2. How Resilient Is the Fuel Strategy? 3. How Mature Is the Regulatory Engagement and Progress Toward Licensing a Design? The label "advanced reactor" covers a lot of ground. The technologies underneath it don't share the same commercial or execution risk.

This week Jim Howe, Terrestrial Energy VP of Government Relations, joined a panel of industry experts at the @US_NIC’s session on nuclear fuel with the Congressional Advanced Nuclear Caucus. Jim's message was clear: fuel choice is a commercial decision, not just a technical one. Terrestrial Energy's IMSR plants run on standard-assay low-enriched uranium (LEU) — available today from multiple western suppliers — avoiding the high costs and supply challenges that come with the higher enrichment levels most advanced reactors require. He also highlighted Terrestrial Energy's mature supply chain for fuel and key components, anchored by commercial relationships already in place — one more reason IMSR is positioned to deploy at fleet scale.

Thank you @US_NIC for including us in yesterday’s important discussion on the future of nuclear energy in the U.S.

On the heels of being awarded “Highly Commended” Technology of Change – Energy Efficiency Award at the Reuters 2026 Energy Industry Awards, our CEO, Simon Irish, recently joined industry leaders at Reuters Events Global Energy Forum 2026 for the “The New Investment Equation: Resilience Over Risk Panel.” For the first time, private capital is funding nuclear technology opportunities pursued by private sector innovators, and screening for the most viable, scalable and capital efficient technologies – those that lower capital requirements, plant construction times, and cost of nuclear energy supply, while improving plant output efficiency and reducing supply chain and regulatory requirements. Capital is funding the transition from technology development to project-level deployment. Simon offered insights on how projects secure capital, exploring global investment flows, de-risking strategies, and the partnerships that unlock financing specifically highlighting Terrestrial Energy’s IMSR Plant as a practical example. By design, the IMSR captures the special “triple-advantage” of molten salt reactor technology – high-temperature and low-pressure operating with inherent safety, making it stand out in the nuclear tech sector for its high capital efficiency while avoiding fuel supply chain challenges from its use of readily-available low enriched uranium (at <5% U-235). Thank you to Reuters Events and the fellow panelists for an insightful conversation. #GEF #IMSR #Energy

Earlier this month in Warsaw, Poland, our VP of Business Development, Sarfraz Taj, participated in the "Beyond Government Dependency: Rethinking Ownership Strategies for FOAK" panel at the DEPLOY SMR Project Financing Workshop, hosted by the U.S. Department of Commerce and the International Trade Administration. The discussion reinforced an important reality for advanced nuclear: successful deployment will require more than technological innovation; it will also require new approaches to project ownership, risk allocation, and financing that can attract private capital. “At Terrestrial Energy, we believe the economics of advanced nuclear must be designed into the technology from the start, and that has been one of our core focus areas for more than a decade,” said Sarfraz. “Our Integral Molten Salt Reactor (IMSR) Plant combines the advantages of Generation IV molten salt reactor technology with a small, modular plant design, delivering high-temperature industrial heat and electricity with a focus on capital efficiency and commercial competitiveness.” The IMSR's high-temperature, low-pressure operation, use of readily available standard-assay low-enriched uranium fuel (LEU), and ability to serve both power and industrial heat markets create opportunities for innovative commercial structures that extend well beyond traditional utility ownership models. As demand grows for reliable, clean energy to support industrial decarbonization, manufacturing, data centers, and energy security, financing models must evolve alongside the technology itself. Conversations like those at DEPLOY are critical to building the partnerships needed to bring first-of-a-kind projects to market. #IMSR #NuclearEnergy #CleanEnergy
