America must lead on nuclear— our national security, energy independence and economic future depend on it. We commend President Trump and his administration on today’s executive orders, which are the clearest signal to date that America is ready to go big and win on nuclear energy. As AI and emerging technologies accelerate energy demand, X-energy remains committed to working closely with the administration through initiatives like the Advanced Reactor Demonstration Program and alongside our commercial partners to accelerate nuclear deployments and strengthen U.S. energy security.

About us
X-energy is delivering the next generation of carbon-free energy by reinventing nuclear power. We believe in leaving a cleaner planet for our children and grandchildren, while continuing to provide sufficient and affordable power to sustain growing populations around the world. That is why we have reinvented nuclear power, with a unique combination of proven technologies and new innovations, to meet our current and future needs. X-energy manufactures fuel that seals uranium particles in a protective coating, which makes meltdown impossible and retains the waste inside forever. We also design plants that unlock the fuel’s potential in a process that’s as clean as wind or solar. When combined, the result is reliable carbon-free baseload power, produced more safely and affordable than ever before and available anywhere, at any time.

#ICYMI As part of our participation in the U.S. Department of Energy (DOE) Reactor Demonstration Program (ARDP), X-energy will soon receive its first tranche of high-assay low-enriched uranium (HALEU) under the DOE’s HALEU Availability Program. This allocation will support the initial core loads for our first commercial deployment in partnership with Dow at their UCC Seadrift Operations site on the Texas Gulf Coast. Together, we're reimagining how we power industrial manufacturing, and paving the way for a cleaner, more secure energy future. https://lnkd.in/egZ8FQfm

We are pleased that the U.S. Nuclear Regulatory Commission has formally docketed and accepted the Construction Permit Application for Project Long Mott! This marks an important step forward as we continue making progress toward commercializing our Xe-100 advanced reactor technology in partnership with Dow. This milestone brings us another step closer to delivering clean, safe, and reliable energy that empowers communities and industries around the world. Ultimately, this progress is possible because of the dedication and hard work of our entire X-energy and TRISO-X team. Check out our careers page to learn more about how you can be part of the future of clean energy! https://lnkd.in/eHYChSvh

Today, we recognize the mother of #nuclearenergy: Marie Curie. Her groundbreaking research on radioactivity—and the discovery of radium—not only earned her two Nobel Prizes, but also laid the scientific foundation for what would become one of the most powerful energy sources in the world. By revealing that radioactive elements emit energy from the nucleus of an atom, Curie opened the door to our modern understanding of nuclear physics. Her work ultimately made possible the development of nuclear fission—the same process that powers nuclear reactors today and provides clean, reliable electricity around the world.

X-energy congratulates our friends at Ontario Power Generation (OPG) and GE Vernova Hitachi Nuclear Energy for advancing the Darlington New Nuclear Project to construction. As one of North America's first grid-scale Small Modular Reactors (SMR), this project marks a transformative moment for the energy sector and a bold step toward a stronger and more secure energy future. OPG has demonstrated a clear commitment to advancing innovative nuclear technologies. As both a commercial partner and investor in X-energy, we are proud to stand alongside them as they lead the way in deploying next-generation energy solutions. We look forward to continuing our strong collaboration with OPG and supporting the success of the Darlington project.
🚨 We are cleared for construction and set to begin building North America’s first commercial SMR at Darlington! With the Province’s green light, we are moving from vision to reality with Ontario’s first new nuclear build in over 30 years. The site is prepped, parts are in motion, and the foundation is ready for this made-in-Ontario project—with about 80% of project spending going to Ontario companies. This fleet of small but mighty reactors will help power Ontario’s future growth and generate major economic benefits, including thousands of high-quality jobs. The future of nuclear starts right here. Learn more about this historic achievement. https://bit.ly/42QtVl3 #BigThingsStartSmall

In a recent Reuters article, X-energy CEO J. Clay Sell shared that the Texas Advanced Nuclear Reactor Working Group, developed by Governor Greg Abbott in 2023, provides a powerful platform for SMR developers to deepen connections across key sectors, including government, manufacturing, utilities, and education. These strengthened ties aren’t just encouraging—they’re essential. Building strong partnerships across the energy ecosystem will be a catalyst for accelerating the deployment of small modular reactors and advancing clean energy innovation. https://lnkd.in/exJKTK_j

"It's not an option for us to get second in AI." We agree with U.S. Department of Energy (DOE) Secretary Chris Wright, and we need #nuclearenergy to meet this moment. X-energy is proud to be leading the way toward commercializing advanced nuclear so we can maintain American leadership and meet growing demand for clean, safe, reliable energy.

Partnerships drive progress. Fantastic to see X-energy highlighted in the U.S. Department of Energy (DOE)'s recent blog on nuclear wins. Our project with Dow in Seadrift, Texas – enabled by the Advanced Reactor Demonstration Program (ARDP) – is a great example of how public-private partnerships are working to advance nuclear power in America. We’re proud to be leading the way in commercializing this important technology.
