Oklo

Oklo’s mission is to provide clean, reliable, affordable energy through the deployment of next-generation fast fission technology and recycling nuclear waste.

[Oklo @oklo]

Building nuclear means advancing multiple pieces of work at once, and Oklo has been busy.

Over the past year, we moved from planning to execution: construction began @INL for Aurora-INL in Idaho, key partners like @Kiewit and @Siemens_Energy were locked in, fuel milestones were cleared, a fuel recycling facility was unveiled in Tennessee, and advanced our Radioisotopes Pilot Facility in Texas.

And the work continues. Watch below ↓

What keeps a reactor safe? In Oklo’s Aurora powerhouse, safety is built into the physics. 

Inherent physical responses automatically stabilize the reactor under changing conditions. That means the same forces that drive the operation also stabilize it.

These principles were proven 40 years ago in reactors like Experimental Breeder Reactor-II & Fast Flux Test Facility. Now, those same principles are the foundation for Oklo’s fast reactor technology today. 

Proven in practice, not just theory.

Last month, Oklo CEO Jake DeWitte joined @SpencerJCox and the @abundanceinst at the Operation Gigawatt Summit in Utah.

The discussions focused on the growing role advanced nuclear can play in meeting rising energy demand from AI, data centers, industrial growth, and electrification.

The summit also highlighted the opportunities nuclear can create across research, workforce development, supply chains, and economic development. That interest is reflected in Governor Cox's engagement with the industry—from policy conversations to attending milestones like Oklo's Aurora powerhouse groundbreaking at Idaho National Laboratory last year.

Oklo CEO Jacob DeWitte joined @MariaBartiromo on @MorningsMaria to discuss the momentum behind advanced nuclear and the work Oklo is doing to deliver clean, reliable power and critical isotopes.

From advancing negotiations under the @ENERGY’s Surplus Plutonium Utilization Program to partnering with @Meta to support growing data center demand in Ohio and approaching criticality with our isotope test reactor in Texas, Oklo is putting the pieces in place to accelerate deployment across its power, fuel, and isotope businesses.

One year ago, America recommitted itself to a nuclear renaissance. One year later, Oklo is helping make it real.

Construction is advancing at our first commercial Aurora powerhouse at @INL. Licensing work continues moving forward with the @NRCgov and DOE. We broke ground on our isotope reactor in Texas and are targeting criticality by July 4th.

Construction. Fuel. Licensing. Isotopes. Partnerships. 

The pieces are moving together faster than many thought possible.

🇺🇸From the White House: Oklo CEO Jacob DeWitte joined President Trump today as he signed Executive Orders to fast-track nuclear deployment, including regulatory path, fuel, and sites.

This week i was in Idaho to visit a couple of our sites. First up, the Aurora-INL site. ~ 100 people on site every day, working 24/7. Kiewit killing it as a partner, both moving efficiently and with a safety first culture.

[Oklo @oklo]

Today, Oklo was selected by @ENERGY for advanced negotiations under the Surplus Plutonium Utilization Program, supporting a pathway to convert surplus plutonium already designated for disposal into bridge fuel for advanced reactors to deliver clean, reliable power.

Oklo’s VP of Fuel Recycling, @EdPetitDeMange, joined @ORNL’s The Sound of Science podcast to discuss why fuel recycling matters now more than ever before, how Oklo is integrating fuel supply directly into its business model, and what it takes to build a modern commercial fuel cycle in the United States.

In less than two months, Oklo’s isotope test reactor will go critical.

We’re building, iterating, and executing in real time across power, fuel, and isotopes.

At @INL, Oklo has moved from site mobilization into deep foundation excavation for our first commercial Aurora powerhouse.

What makes this moment significant is not just the physical progress at the site, but the coordinated progress taking shape across the entire project.

Construction, fuel, and licensing are all advancing at a pace that once seemed inconceivable. Oklo is demonstrating what is possible when the critical pieces move forward in parallel.

[Oklo @oklo]

Fast reactor technology is the foundation that connects Oklo's power, fuel, and isotope business lines into one integrated system.

Our fast-fission powerhouses provide clean, always-on electricity while enabling practical fuel recycling, which can produce isotopes for medical, industrial, space, and national security applications.

Together, these business lines function as one platform that maximizes value across the nuclear lifecycle.

[Oklo @oklo]

Oklo is partnering with @Battelle to integrate @INL’s Prometheus AI platform into Oklo’s reactor and fuel-system design workflows.

As advanced reactors like the ones Oklo is commercializing move toward deployment, scaling engineering workflows becomes increasingly important.

This collaboration combines Oklo’s reactor and fuel development work with INL’s technical expertise and AI infrastructure to help build the systems and tools to support the commercialization and deployment of Oklo’s advanced nuclear powerhouses.

Big news for Oklo’s Aurora reactor site in Idaho: @NRCgov approved our Principal Design Criteria topical report.

Completed in less than half the traditional review timeline, this approval establishes the core safety and design framework for our Aurora powerhouse. 

It also means approved content can be referenced in future applications without being re-reviewed, helping support faster licensing work.

For Oklo, this is a critical step toward repeatable deployment that keeps safety at the center.

Yesterday, Oklo hosted EBR-II veterans and partners at @INL to mark the start of construction on our Aurora Fuel Fabrication facility, where used fuel from EBR-II will help power our first Aurora powerhouse.

It was a special moment connecting past, present, and future, and recognizing the people whose decades-long work on advanced fast reactor technology demonstrated inherent safety, and proved the value of fast-fission systems that can run on recycled fuel through an integrated fuel cycle. That work forged the foundations for Oklo’s advanced reactor design today.

Advanced nuclear technologies aren’t just transforming how we power the future.

They are also enabling materials that can save  lives and support space exploration.

Last month, we celebrated a huge milestone for Oklo’s isotopes business line.

The @NRCgov has granted us a license to handle, process, and distribute isotopes – making Oklo one of the first advanced nuclear companies licensed to sell isotopes. 🧵

[Oklo @oklo]

This license marks an important step toward strengthening the U.S.  supply of critical isotopes and advancing domestic commercial production of materials that support medicine, industry, and space exploration.

Oklo CEO Jacob DeWitte joined @BloombergTV to discuss Oklo's progression toward criticality and what it takes to bring advanced nuclear systems online.

With our isotope test reactor in Texas just months away from reaching criticality.

As demand for computing capabilities accelerates, Oklo is collaborating with @NVIDIA and @LosAlamosNatLab to advance nuclear fuel validation, AI-enabled nuclear R&D, and infrastructure studies in support of future nuclear-powered AI factories.

This is how computing and energy research come together to support what’s next.

Oklo CEO Jacob DeWitte joined @LizClaman on @FoxBusiness to discuss why nuclear is the clear solution for power in space.

Nuclear has powered missions for decades through isotope systems that deliver continuous energy where others can’t.

At Oklo, we’re building the systems that support both the present and the future, including our isotope test reactor that will reach criticality by July 4.
