DeepFission

Nuclear energy company placing small modular reactors a mile underground.

[DeepFission @DeepFission]

We’re excited to announce our partnership with @DayZim for the construction of our Gravity #Nuclear Reactor.

They will oversee the project’s pre-construction planning and perform above-ground construction.

Our Senior Nuclear Operations Engineer Tim Gnadt recently represented our team at @ExcelEngMN’s 21st Annual Technical Conference, sharing insights on innovation in the SMR space and @DeepFission’s approach to underground #nuclear deployment.

We’re using established PWR tech designed to operate one mile underground, where surrounding geology is intended to provide a natural layer of protection. The system is designed to generate electricity in a highly monitored + regulated environment.

[DeepFission @DeepFission]

Our @DeepFission surface systems team recently met in Parsons, Kansas, to discuss plans to deliver one-mile-deep #nuclear power systems. At this depth, geological isolation is expected to naturally provide essential pressure control + enhance safety.

We believe this next phase will play an important role in advancing site characterization and development efforts as we continue progressing toward deployment of our one-mile-deep #NuclearEnergy systems.

We finished ground preparations this past week for our second test well in Parsons, Kansas, which we intend to use to demonstrate deep deployment (~2500 ft) of major components and to test borehole thermal behavior.

[DeepFission @DeepFission]

As part of our testing, we also expect to use the well to lower a prototype reactor underground to help validate key aspects of our deployment approach.

Deep Fission's reactors will use a fuel called Low Enriched Uranium (LEU). This fuel type is typically enriched to about 3–5%.

LEU is engineered for one purpose: ➡️ Powering #nuclear reactors to deliver consistent, reliable electricity.

[DeepFission @DeepFission]

Thank you to the Parsons #Kansas community for joining us last night to discuss @DeepFission’s #nuclear project at Great Plains Industrial Park.

Our COO Mike Brasel shared project updates alongside @KState's Amir Bahadori, followed by a moderated Q&A.

[DeepFission @DeepFission]

Our @DeepFission Gravity Nuclear Reactor aims to leverage existing capabilities developed in the oil, gas and geothermal industries to deploy established pressurized water reactor (PWR) technology in a new way.

➡️ 4 Empire State Buildings
➡️ ~9 Space Needles
➡️ Halfway+ across the Golden Gate Bridge

That’s the scale of a Deep Fission borehole.
By taking #nuclear 1 mile underground, we aim to deliver scalable power with natural containment + a smaller footprint.

.@DeepFission cofounder Liz Muller grew up in a home supportive of #NuclearEnergy, yet was surrounded by skeptics.

After living in France — where #nuclear is widely embraced — she returned to the U.S. asking: Why aren’t we doing more with nuclear? 🎥⬇️

[DeepFission @DeepFission]

The typical U.S. salary is about $60–$65k a year. A #nuclear reactor operator earns closer to $123k. ⚛️

That’s not just a paycheck—it’s stability, homeownership and long-term growth.

We’re working to make #careers like this possible in more communities: https://t.co/QpCgxh8SEB

[DeepFission @DeepFission]

We’re not trying to invent a new type of #nuclear reactor @DeepFission, we’re building on what works.

Pressurized water reactors have safely provided commercial power for decades.

64 operate in the U.S. today, generating ~12% of our electricity ⚛️

We were proud to join the @ChamberParsons golf tournament this past weekend and spend time connecting with the community that’s central to our work.

Our swings may need some refining, but our commitment to Parsons, Kansas is right on par. 😉⛳
