DeepFission

We have officially started drilling the first borehole for our data acquisition well in Parsons, Kansas -- a major milestone as we move from planning and engineering into active field development. Check out our website for the full announcement.

We’re excited to share that we've signed a multi-year Master Services Agreement with Accelerant Solutions to support the development and implementation of our quality and reactor operator training programs. See the full announcement on our website.

We've signed an agreement with @urencousa to supply low-enriched uranium (LEU) for testing and demonstration of our initial Gravity Reactor as part of the DOE’s Reactor Pilot Program, and to support early commercial operations. Check out our website for full announcement.

🇺🇸 @DeepFission Raises Additional $80 Million For Underground #Nuclear Reactor Deployment. #NuclearPower #NuclearEnergy Proprietary design combines PWR technology with deep borehole drilling techniques 👉 nucnet.org/news/deep-fiss…

@OilandEnergy so fracking (which is SAFE) is evil ... but underground storage of highly radioactive waste is cool now?

Deep Fission estimates that its innovative approach can slash construction costs by as much as 80 percent. bit.ly/4qvmBnu

We’ve raised $80 million in new financing to accelerate commercialization of our advanced nuclear technology. Blue Owl Capital’s Real Assets platform is a new strategic relationship, and a Blue Owl managed fund participated in the round. Full announcement on our website.

ICYMI our CEO appeared on CNBC to discuss Deep Fission's official groundbreaking in Kansas! You can check out the full segment here: cnbc.com/video/2025/12/…

Historic moment: We broke ground in KS yesterday -- the 1st major nuclear groundbreaking since 1977! We turned on the rig, drilled our first test hole, marking the kickoff of the Reactor Pilot Project. We have a lot of work to do between now and July 4, 2026 -- let's build!

Our CEO Liz Muller will be on CNBC Europe tomorrow to discuss our Kansas groundbreaking and what’s ahead for advanced nuclear. Tune in live or watch the clip later!

California-based startup @DeepFission has chosen Great Plains Industrial Park in Parsons, Kansas, for its pilot project and plans to a build a full-scale commercial plant there following the test reactor demonstration #nuclear tinyurl.com/4tkenpx8

@DeepFission has developed an innovative way to speed up deployment and meet some of the safety, environmental and cost issues around #nuclearenergy: placing small modular reactors in boreholes one mile underground. theinnovator.news/startup-of-the…

We've selected the Great Plains Industrial Park in KS as the site for our first Department of @ENERGY pilot reactor. Breaking ground Dec 9. We plan to pursue a full-scale commercial project at the site after a successful demonstration. The future of nuclear is a mile deep.

We've signed an Other Transaction Agreement (OTA) with the U.S. Department of @ENERGY to build our first test reactor and aim for criticality by July 4, 2026, under the Reactor Pilot Program. This is a major step for American energy dominance and advanced nuclear.

We're proud to introduce Gravity - the official name of our deep borehole reactor! By placing our Gravity reactors deep underground, we’re tapping into Earth’s natural forces to make nuclear power inherently safer, dramatically more cost-efficient, and faster to deploy.

Mike Brasel has been promoted to COO at Deep Fission. He has been a key part of the team since early on & his technical depth and operational leadership will be essential as we look to build our 1st reactor in 2026 as part of the DOE's Reactor Pilot Program.

Despite being a newbie to nuclear, it's obvious it will be a key form of clean, abundant energy to power the new economy. I just released the full conversation (link below) with Liz Muller from @DeepFission . They're building micro-nuclear reactors 1-mile underground.

On #VeteransDay, we honor all who have served and continue to serve our country. 🇺🇸 We are especially grateful to the veterans on our team who are helping to build a better tomorrow. Thank you for your service!

Last week, the Deep Fission team took over Vegas for our quarterly offsite! We may be a work-from-anywhere company, but there’s nothing like coming together IRL - a little business, some fun, and a lot of energy.
