WE HAVE CRITICALITY! Oklo has completed first criticality at its Groves Isotope Test Reactor. Built in less than a year under the @ENERGY’s Reactor Pilot Program, Groves offers a concrete blueprint for future advanced nuclear deployment as the fastest fully privately financed and built reactor project of its kind. Today, Oklo proves that advanced reactors can be built, started, and operated faster than anyone thought possible and shows the world that America can build nuclear again. oklo.com/newsroom/news-detai…

As the U.S. looks to quadruple nuclear generation by 2050, it will need a fuel strategy that can power that growth.  Nuclear fuel recycling can support a more sustainable and economical path by recovering more energy from used nuclear fuel, reducing the need for newly mined uranium, and shrinking the amount of waste that requires long-term management. That shift toward a more integrated approach to nuclear generation, fuel, and waste management is taking shape through efforts like the @ENERGY’s Nuclear Lifecycle Innovation Campuses. Our partnership and research with @argonne will help Oklo advance toward recycling commercialization, making this vision a reality.

In case you missed it: the nuclear comeback is underway, and Oklo is building it. A few weeks ago, just after reaching criticality at the Groves Isotope Test Reactor, CEO Jake DeWitte brought @tboypod’s @NickOfNewYork & @jackkramer along for a tour of the facility and to unpack the ideas behind Oklo’s efforts to build a new approach to nuclear. They cover how fast reactors work, what criticality actually means, why Oklo is investing in fuel recycling technology now, and why the conversation around America’s growing power demand is putting nuclear back at the center of the energy debate.

“It’s a resource. If we can use all this energy and recycle it and do it again and again and again, why aren’t we doing this?”  When people think about used nuclear fuel, they often see waste. Oklo’s Senior Director of Fuel Cycle Technology, Dr. Christina Leggett, sees it as a resource. Advanced fuel recycling can recover valuable material that can be made into new fuel for future powerhouses. It can also create opportunities to recover critical isotopes that support healthcare, research, national security, and even space exploration. Hear why Dr. Leggett believes we should get more value from the nuclear materials we already have.

Scaling advanced nuclear will require cultivating a new generation of skilled workers across engineering, manufacturing, construction, operations, and other fields. That was the focus of Oklo Vice President of Product Integration Scott Auerbach’s conversations today at Climate Week. He joined industry leaders to discuss how to build the workforce needed to support nuclear growth, from creating new career pathways and investing in training to ensuring the talent pipeline keeps pace with deployment.

Oklo’s Chief Financial Officer Craig Bealmear joined Stefano Buono, Chief Executive Officer, @newcleoenergy, Jacob Stedman, Chief Executive Officer, Blykalla, and Amir Vexler, President and CEO, @centrus_energy, plus Amy Roma, Partner at @Orrick, at the @Atlantic Council’s Nuclear Energy Policy Summit for a conversation on how to meet rising electricity demand. The entire panel agreed: it’s time to execute on the opportunity in advanced nuclear energy. As Craig shared, Oklo is moving from proving what is possible to proving what can be deployed repeatedly and at commercial scale. Speed and execution will be critical as the industry works together to bring more clean, reliable power online – and at a pace fast enough to keep up with a growing and evolving economy.

New York, we’re on our way. Advanced nuclear is a climate solution within reach—and Oklo is coming to Climate Week NYC to discuss what it takes to deploy it at scale. Throughout the week, our leaders will join conversations about delivering clean, always-on power, unlocking more energy from used nuclear fuel through recycling, and training the workforce needed to support industry growth and the energy transition.  Looking for somewhere to recharge? Meet us at the Oklo Lounge at @Axios House at GH on the Park—we’ll have charging stations, coffee, and more to keep you and your devices fueled.  Join us in New York and follow along here as we share perspectives from our team, highlights from the week, and a closer look at how Oklo is working to deliver clean, reliable power at scale.

The 1st podcast recorded inside a nuclear reactor. We sat down with @jakedewitte, co-founder and CEO of @oklo, just feet from actual splitting atoms. We talked about why nuclear got cancelled in the 80s, and how his nuclear is safer, recycles nuclear waste, and (*checks notes*) fights cancer. This one’s special, Yetis. WATCH the full episode wherever you get your pods!

Not every podcast is recorded at the site of a functioning nuclear reactor. Shortly after criticality at the Groves Isotope Test Reactor, Oklo CEO Jake DeWitte welcomed @tboypod’s @NickOfNewYork & @jackkramer onsite for a look at the infrastructure and approach behind the milestone. Their conversation explored the lessons learned from Groves as the fastest-built fully privately financed reactor project of its kind, as well as how Oklo’s integrated platform across power, fuel, and isotopes is creating a more flexible path to scaling advanced nuclear. They also discussed what comes next for Oklo, from meeting growing demand for clean, reliable power to investing in domestic fuel capabilities to get ahead of constraints and producing critical isotopes for medicine, space, and other essential applications.

Oklo is proud to be investing in Tennessee and contributing to the state’s next chapter of nuclear innovation. We’re building on Tennessee’s nuclear legacy with plans to develop America’s first privately funded advanced nuclear fuel recycling and manufacturing facility in Oak Ridge. The center aims to create more than 800 high-quality jobs and help establish a secure domestic fuel supply for the next generation of advanced nuclear reactors. We’re excited to keep building with Tennessee’s people and communities!

Electricity demand is surging, and meeting that demand will require clean, reliable, and affordable power at scale. Advanced nuclear can support growing power demand while strengthening domestic fuel supply and making better use of nuclear materials. Oklo is building an integrated platform across power, fuel, and isotopes to help build a more resilient energy system.  Read more in our @Nature partner content: nature.com/articles/d42473-0…

Oklo co-founder and COO @caorilne joined @PaulHShapiro on the Business for Good podcast to discuss her decade-long journey building Oklo and why Groves reaching criticality means much more than just starting up a reactor. Built from the ground up in less than a year, the Groves Isotope Test Reactor gave Oklo hands-on experience across engineering, construction, regulatory execution, operator training, security, quality assurance, startup, and operations. That experience creates a foundation Oklo can build on to advance commercial-scale isotope production, fuel fabrication, and planned Aurora powerhouse deployments. Listen to the full conversation: piped.video/watch?v=9bO4oqRh…

Reaching criticality at Groves was a major milestone. It was also just the beginning. In less than a year, Oklo built our Groves Isotope Test Reactor from the ground up and brought it to criticality, demonstrating our ability to move from design to operation on a timeline few thought possible. What we learned extends far beyond Groves. The project gave our team hands-on experience across engineering, construction, regulatory execution, startup, and operations that we can apply as we advance projects across power, fuel, and isotopes. Now, we're putting that experience to work as we build toward commercial scale. That includes targeting our first commercial isotope revenue in early 2027 through our NRC-licensed Idaho Radioisotope Laboratory, while advancing our power and fuel projects toward deployment. Groves demonstrated our ability to build, learn, and repeat. Now, we're doing it across the business. piped.video/0H8A4jXKuyA?si=Pm2M…

As demand for power soars and advanced nuclear moves rapidly toward commercial-scale deployment, fuel is emerging as one of the industry’s most critical bottlenecks. At Oklo, we’ve been building around that reality. Our strategy is designed to secure fuel for near-term deployments while domestic HALEU production scales and we develop the capabilities to recycle used nuclear fuel into new fuel for the long term. Potential access to U.S. surplus plutonium could provide an important bridge along the way. But our long-term strategy goes much further. In Oak Ridge, Tennessee, Oklo plans to invest nearly $1.7 billion in an advanced fuel center anchored by a commercial-scale fuel recycling facility. The facility designed to turn existing nuclear materials into new fuel, helping build the domestic fuel supply needed to support advanced nuclear at scale. Building reactors is only part of the equation. We’re building the fuel infrastructure to power them, too. Read more in the @FT: giftarticle.ft.com/giftartic…

Most nuclear fuel is used once. Fuel goes in, energy comes out, and ~95% of the energy remains unused. Fuel recycling changes that. Material is recovered and reused to extract more energy and reduce what’s left to manage. Using more of what we already have by recycling nuclear waste to recharge America.

Oklo is proud to be among the 12 developers joining @GovNuclear’s Nuclear Energy Launch Pad initiative, run by the National Reactor Innovation Center (NRIC). The Initiative builds on the success of @ENERGY’s Reactor Pilot Program and Fuel Line Pilot Program, giving participants a prioritized pathway to DOE authorization backed by national lab infrastructure, technical expertise, and regulatory support tailored to each project. Oklo has advanced three projects through the original Reactor Pilot Program, including our Groves Isotope Test Reactor, which was built and taken from greenfield to criticality in less than a year.  Selection for the Launch Pad builds on what Groves demonstrated: advanced nuclear can move quickly when the right technology, infrastructure, and regulatory pathways come together. That model is gaining momentum across the industry and helping move a new generation of American nuclear projects toward deployment.

For engineers like Patrick, our Groves isotope test reactor is proof that advanced nuclear can be built differently. Built from the ground up in less than a year and on track to reach criticality this month, Groves is demonstrating a faster, more repeatable path to deployment. Hear Patrick describe the significance of this moment. Learn more about our isotopes work here: piped.video/EXAFYdrmdeU

America is building nuclear again, and Oklo is on the front lines. At @INL, construction is advancing on our first commercial Aurora powerhouse, turning engineering, planning, and preparation into real infrastructure. The work at INL is laying the foundation for a commercial deployment that can scale. As demand for reliable power grows, we’re building toward a model designed to move safer and faster than nuclear has ever moved before.  Read more about how Oklo is leading the race to build America’s next generation of nuclear energy in the @WSJ: wsj.com/finance/investing/in…

“By all accounts and measures, this is the fastest-built, privately sited, privately funded, privately built nuclear reactor in world history.” Oklo CEO Jacob DeWitte took CBS Austin’s @waltmac inside of the Groves Isotope Test Reactor, just days after reaching criticality. Built in less than a year, Groves serves as the technical and operational foundation for Oklo’s commercial isotope production, which will help restore America’s supply of critical isotopes for applications in medicine, manufacturing, research, national security, space exploration, and beyond.  Go inside Groves with @cbsaustin: cbsaustin.com/news/local/okl…

There is a lot happening right now. Last week was a good example. We welcomed @ScienceUnderSec and @CongMikeSimpson to @INL, traveled to Texas to see @Oklo’s Groves-1 go critical, and hosted @NASAAdmin Jared Isaacman and @ENERGY Deputy Secretary Danly. Industry. Government. National labs. Never in my career have I seen all three aligned like they are right now. We can’t take this moment for granted. #NuclearEnergy #AdvancedNuclear #EnergyDominance #SpaceExploration
