This was even much more than a construction project. Startup of a private facility means honing and implementing operating procedures, training programs, security programs, environment, health and safety programs, quality assurance programs and procedures, and much more. Oklo's centers of excellence on all of these operational aspects now have this experience to bring to all our projects currently in progress and to build on for the future!

[Oklo @oklo]

Oklo CEO Jacob DeWitte joined @CNBCMorningCall to discuss two major milestones for Oklo: startup authorization for our Groves Isotope Test Reactor and our founding membership in Prometheus.

Yesterday’s @ENERGY authorization clears the way to load fuel and bring the fastest privately built reactor of its kind to first criticality. This week, Oklo also joined Prometheus, a DOE-supported initiative led by @INL to unleash AI across the nuclear lifecycle.

Both of these milestones reflect the momentum behind a new era of nuclear development and the opportunity to use AI to help deliver clean, reliable power more quickly.

GREEN LIGHT FOR STARTUP: @ENERGY has authorized Oklo’s Groves Isotope Test reactor to begin nuclear operations.

This startup authorization clears the facility and team to bring in fuel, run startup tests, and proceed toward first criticality under its startup plan.

In just over 10 months , Groves completed engineering, construction, commissioning, development of operating programs, personnel training, and DOE readiness across all core requirements. Oklo chose the harder path to build a repeatable deployment model on private land using commercially procured fuel and equipment so future Aurora powerhouses, isotope facilities, and fuel cycle projects can build on proven deployment capabilities  instead of starting from scratch.

Lessons from Groves are already informing how we build our other capabilities, demonstrating  how advanced nuclear can move faster under DOE’s Reactor Pilot Program while keeping safety front and center.

Oklo is excited to be a founding member of Prometheus, an initiative led by @INL and selected by @ENERGY for a $60M phase 1 award over three years.

Prometheus brings together 32 partners across national laboratories, academia, and industry to explore how AI can streamline engineering, manufacturing, licensing, and operations to help reduce development timelines and lower the cost of deploying safe, reliable nuclear energy.

We look forward to contributing our experience alongside partners across the nuclear ecosystem as we work to help build the next era of energy infrastructure.

The Intermountain-West Nuclear Energy Corridor Tech Hub just received $31M from @CommerceGov's EDA to accelerate #NuclearReactor deployment, speed commercialization of next-gen reactors, and strengthen U.S. #energy security.

INEC brings together 45+ organizations across Idaho and Wyoming. @INL is proud to help lead this effort, alongside the Idaho Advanced Energy Consortium and our many partners.

People also said it was a waste to talk about:
- Palisades (restarting)
- Three Mile Island (restarting thanks to Microsoft buying 20 years of its power)
- Duane Arnold (restarting with a 25 year deal with Google)
- Maanshan (restart application filed in March)
- The Belgian fleet (buyback currently being negotiated with the intention of restarts)

I'll stop harping when the train has actually left the station. Until then, it's worth the energy (which I thankfully have a lot of ✨)

[Oklo @oklo]

@INL has been at the center of nuclear innovation for decades. We're proud to be helping to build the next chapter.

Our work at INL goes beyond one project. It’s about building advanced nuclear in a way that gets the most out of recycled fuel while making advanced reactors more repeatable and deployable.

From reactor development to fuel fabrication and isotope production, our projects are taking shape across the country.

They're all part of a larger system supporting the growing demands of our energy future.

At Oklo we're making real progress and laying the groundwork for a new kind of nuclear tech infrastructure.

[Madi Hilly @MadiHilly]

For years, @energybants and I have been saying one of the best things about Chicago (and there are many) is that it's run on nearly carbon-free power for decades thanks to our local nuclear plants.

Come find out how that legacy was built, what we're doing to build on it, and hear @captain_rogerb explain how our labs are helping invent the future of nuclear.

METL ROCKS 🤘: @Argonne is home to the largest liquid metal test facility in the U.S.

It’s used to test small and medium-sized components that will be used in sodium-cooled fast reactors.

[Oklo @oklo]

Carla is Oklo’s Technical Advisor, with 30 years of experience building and operating nuclear infrastructure.

Today, she's helping rebuild America's domestic supply of isotopes, starting with Oklo's Groves Isotope Test Reactor, a project that will expand domestic isotope production while demonstrating a faster, more scalable approach to advanced nuclear deployment.

Hear, in her own words, why this work is so meaningful.

Travel with toddlers is an amazing way to find out that home was the vacation all along 😅

But we had a couple good lake days over the holiday weekend 🇺🇸

Happy belated 250th Independence Day everyone!

[Oklo @oklo]

Oklo’s momentum is changing the paradigm of how we build advanced nuclear in the United States.

Our Groves isotope test reactor is the only reactor built on privately owned land using commercially sourced fuel, equipment, and systems to receive Documented Safety Analysis approval under the @ENERGY Reactor Pilot Program.

Oklo CEO Jacob DeWitte spoke with @LizClaman on @FoxBusiness about how this project is establishing a new blueprint for how nuclear can scale in America:

[Oklo @oklo]

We were proud to welcome @ENERGY @SecretaryWright to @INL, where significant progress is underway on our first commercial Aurora powerhouse.

Together with the strides we're making toward criticality at our Groves Isotope Test Reactor in Texas, Oklo’s work on full civil nuclear facilities is moving forward on multiple fronts. Construction, fuel, licensing, and engineering are advancing in parallel, compressing timelines and redefining the pace of advanced nuclear deployment.

We're grateful for Secretary Wright's leadership and the continued partnership of DOE and INL as we work together to turn advanced nuclear from ambition into deployment.

[Oklo @oklo]

For decades, the U.S. has stored surplus plutonium at significant cost to taxpayers.

Oklo’s fast reactors use that material as fuel, generating clean, reliable electricity while consuming it through fission.

As the nuclear supply chain scales, plutonium will serve as a bridge fuel, turning legacy material into a national asset that strengthens U.S. leadership in advanced nuclear technology.

As Oklo CEO Jake DeWitte told @MattMiller1973 on @Bloomberg News, Oklo is building the ‘full stack’ for advanced nuclear.

By investing in the full reactor lifecycle from supply chains to construction to operation, we’re learning how to make advanced nuclear deployment faster, more repeatable, and more scalable.

[Oklo @oklo]

At our Groves site in Lockhart, Texas, Oklo reached substantial completion of our isotope test reactor in just 229 days and is working toward criticality this July, making it one of the fastest-built reactors since the Manhattan Project.

Once operational, Groves will support the production of critical isotopes used across medicine, industry, research, and other essential applications.

[Caroline DeWitte @caorilne]

We've long had access to fuel material for our foak, thanks to our 2016 mou with doe, but this partnership, plutonium, and recycling make Oklo far and away positioned for scale.

We've always said it would be a failure if we just built one plant. swinging through the ball!

[Caroline DeWitte @caorilne]

The sign makes it super official

[Oklo @oklo]

Fuel availability remains one of the biggest constraints facing advanced nuclear.

Today, Oklo and @Centrus_Energy signed a Letter of Intent for the supply of domestically sourced HALEU to support Oklo’s planned Aurora powerhouse deployment and 1.2 GW Clean Energy Campus in southern Ohio. The agreement would provide enough HALEU to support multiple years of reactor cores, covering up to five Aurora powerhouses.

The agreement helps connect fuel supply, power generation, customer demand, and project execution in one region.

Fuel. Power. Demand. Execution.

That’s how advanced nuclear gets built.
