Iftikhar Haque, Vice President of Nuclear Supply Chain for Terrestrial Energy, shares his expertise at the @US_NIC's Advanced Reactor Summit XIII, in Seattle, Washington.  During his panel appearance, Iftikhar described how Terrestrial Energy has built a mature and trusted US-focused supply chain comprised of a leading group of nuclear fuel, services, and component providers to support commercial deployment of the Integral Molten Salt Reactor (IMSR), a Generation 4 technology that delivers best-in-class capital efficiency and low-cost nuclear energy supply.  By using readily available standard-assay low-enriched uranium in its fuel, with contracts in place with top-tier suppliers, through a modular design for fast construction, and with a low-CAPEX business model, Terrestrial Energy is well positioned for rapid IMSR plant deployment.  Learn more at terrestrialenergy.com

Last Wednesday, Terrestrial Energy CEO and Director, Simon Irish, joined the NACD New Jersey Chapter's virtual panel, "Powering the Future: The Role of Nuclear Energy in U.S. Energy Resilience." Simon and a group of industry experts discussed the evolving role of nuclear energy in the U.S. energy landscape under the new Administration, advancements in technology and the investment implications of nuclear energy. Thank you NACD for inviting Simon and Terrestrial Energy to participate in an engaging discussion. #NuclearEnergy #EnergySecurity #SMR

Terrestrial Energy was recently featured in "Nuclear Energy is Bankable Again," an op-ed by Todd Abrajano published in @thehill. The article recognizes Terrestrial Energy as a promising publicly traded nuclear company and highlights our commercial IMSR plant project at the @TAMU System's RELLIS campus. We credit our incredible team behind the work and thank you to Todd for the mention. thehill.com/opinion/energy…

On Wednesday, Terrestrial Energy CEO, Simon Irish, joined the "Capitalizing Innovation: How Technologies Come to Market" panel at @NEI's Nuclear Finance Summit in New York City. He, and a panel of his peers, discussed different approaches to bring advanced reactor technologies to commercial markets.

Today, Terrestrial Energy announced the execution of a second Other Transaction Authority (OTA) agreement with the Department of Energy (DOE) - this time for Project TEFLA under the Fuel Line Pilot Program. This agreement represents a critical step forward in advancing our integrated fuel-to-reactor commercialization strategy. Project TEFLA will demonstrate our proprietary IMSR Fuel Salt production technology at pilot scale, using readily available SALEU fuel and leveraging our existing supplier relationships. The fuel produced will directly support our Project TETRA test reactor, creating a seamless pathway from fuel production to reactor operation. "Projects TEFLA and TETRA deliver critical elements on IMSR plant design and operation via an accelerated DOE authorization pathway," said Simon Irish, CEO of Terrestrial Energy. "These programs encompass key technologies for IMSR plant commercialization, from fuel to reactor supply, and demonstrate our commitment to delivering practical, deployable nuclear solutions that strengthen America's energy security." With two active DOE OTA agreements now in place, we're accelerating toward our goal of delivering flexible, clean firm energy through our commercial IMSR plants in the early 2030s.

Last week, Sarfraz Taj, VP Business Development, participated in a panel titled Unlocking Nuclear Investment: Tackling the Roadblocks to Deployment at the Projects & Money Conference 2026. “The Terrestrial Energy Integral Molten Salt Reactor (IMSR) Plant unlocks investment into new nuclear through transformative capital efficiency and cost improvement. The IMSR Plant’s low-pressure operation eases design requirements and lowers manufacturing costs, and a long, cost-effective LEU fuel cycle further improves economics. The IMSR Plant delivers best-in-class high-temperature thermal output for industrial processes and for electricity generation at ~50% higher efficiency than legacy plants.” “These are some of the many ways our team is focused on removing roadblocks to commercial scale deployment,” said Sarfraz. Terrestrial Energy is working to swiftly commercialize its IMSR advanced reactor technology in order to deliver clean, reliable, and cost-effective high-temperature industrial heat and electricity at scale.

.@TAMU’s plans to advance small nuclear reactor development, as highlighted in the @HoustonChron, reflect the growing momentum behind advanced nuclear energy in Texas and beyond. We are proud to be part of this effort, working alongside academic and industry partners to develop molten salt reactor technology that can deliver safe, reliable, and emission-free power.
