Have you ever wondered what the future of energy might look like? I recently stumbled across a fascinating idea that feels like it’s ripped straight from a sci-fi novel: a startup wants to bury miniature nuclear reactors a mile underground to power our world. It’s bold, it’s innovative, and it’s got me thinking about how we might solve the growing energy demands of our tech-driven lives. This isn’t just about flipping a switch—it’s about reimagining how we generate power in a way that’s safe, efficient, and sustainable.
A New Era for Nuclear Energy
The world’s energy needs are skyrocketing, especially with the rise of AI data centers that guzzle electricity like never before. A forward-thinking company is stepping up with a groundbreaking solution: small, cylindrical nuclear reactors buried deep in the Earth’s bedrock. This isn’t your typical nuclear plant sprawling across acres of land. Instead, these mini-reactors are designed to fit into narrow boreholes, generating clean energy with a fraction of the footprint. It’s the kind of idea that makes you sit up and take notice.
The company recently raised $30 million through an unconventional funding approach, opting for an alternative public offering rather than a traditional IPO. This move allowed them to secure capital at a lower share price, making it accessible to a broader range of investors. With this cash infusion, they’re aiming to build a pilot reactor by mid-2026, a timeline that feels ambitious yet achievable. I can’t help but admire their hustle—it’s a risky bet, but one that could redefine how we think about nuclear power.
Why Bury Reactors Underground?
At first glance, burying a nuclear reactor a mile underground sounds like something out of a dystopian thriller. But when you dig into the logic, it’s surprisingly practical. The concept hinges on using the Earth’s natural bedrock as a shield. By placing these reactors deep underground, the company addresses two major concerns that have long plagued nuclear energy: safety and security.
Burying reactors deep in bedrock offers unparalleled containment and protection, minimizing risks while maximizing efficiency.

Traditional nuclear plants are often criticized for their vulnerability to accidents or external threats, like natural disasters or even sabotage. By contrast, a reactor tucked away in a borehole is shielded by layers of rock, reducing the risk of meltdowns or attacks. Plus, the surface footprint is tiny—think a small drilling site rather than a massive facility. It’s a clever way to tackle public skepticism about nuclear power while keeping things eco-friendly.
- Natural shielding: Bedrock acts as a barrier against radiation leaks.
- Reduced surface impact: Minimal land use compared to traditional plants.
- Enhanced security: Deep placement deters external threats.
Perhaps the most intriguing part is how this approach could make nuclear energy more palatable to communities wary of having reactors nearby. Nobody wants a power plant in their backyard, but a mile underground? That’s a different conversation.
How These Mini-Reactors Work
So, how do you fit a nuclear reactor into a 30-inch borehole? The answer lies in clever engineering. These mini-reactors are cylindrical, compact, and designed to generate around 15 megawatts of power each. They use pressurized water cooling, a tried-and-true method in the nuclear industry, ensuring reliability without reinventing the wheel. The reactors run on low-enriched uranium, which is safer and less controversial than highly enriched fuels.
What’s particularly cool is the use of off-the-shelf components. Instead of custom-built, expensive parts, the company is keeping costs down by using readily available technology. This pragmatic approach could make their reactors not only feasible but also surprisingly affordable, with power generation costs estimated at 5–7 cents per kilowatt-hour. For context, that’s competitive with many renewable energy sources, which is no small feat.
| Feature | Details |
| Reactor Size | 30-inch diameter, cylindrical |
| Power Output | 15 megawatts per reactor |
| Cooling System | Pressurized water |
| Fuel Type | Low-enriched uranium |
| Cost per kWh | 5–7 cents |
In my opinion, the simplicity of this design is what makes it so exciting. It’s not about flashy, untested tech—it’s about taking what works and making it better, safer, and more accessible.
Powering the AI Revolution
One of the biggest drivers behind this innovation is the explosive growth of AI data centers. These facilities require massive amounts of electricity to process complex algorithms and store vast datasets. Traditional energy sources, like coal or gas, are too dirty, and renewables like solar or wind can be inconsistent. Nuclear energy, with its reliability and low carbon footprint, is an ideal match.
The startup has already inked a deal to supply two gigawatts of capacity to a data center developer, signaling strong market interest. This isn’t just a pipe dream—they’re positioning themselves to meet a real, urgent need. As someone who’s watched the tech world evolve, I find it fascinating how industries like AI and nuclear energy are converging to shape the future.
The energy demands of AI are pushing us to rethink how we power the future. Underground reactors could be the answer.

Could this be the key to keeping our tech-driven world humming without frying the planet? It’s a question worth pondering.
Challenges and Opportunities
Of course, no bold idea comes without hurdles. The company’s unconventional funding path, while innovative, brings higher regulatory costs that could strain their budget. Last year, they raised just $4 million, so this $30 million infusion is a game-changer—but it’s still a drop in the bucket for a project of this scale. Building a reactor by 2026 is no small task, and any delays could shake investor confidence.
Then there’s the public perception of nuclear energy. Despite its safety advantages, the word “nuclear” still makes some people nervous. The company will need to communicate clearly and transparently to win over skeptics. In my experience, trust is everything when it comes to game-changing technologies like this.
- Regulatory hurdles: Navigating complex nuclear regulations.
- Public perception: Overcoming fears about nuclear safety.
- Scaling up: Moving from pilot to widespread adoption.
Still, the opportunities are massive. If they can pull this off, they could set a new standard for clean energy, powering everything from data centers to entire communities. It’s the kind of vision that gets me genuinely excited about the future.
What’s Next for Underground Nuclear?
The company’s timeline is aggressive: a pilot reactor by mid-2026, with plans to scale rapidly after that. They’ve already been selected for a government-backed program aiming for first criticality by July 4, 2026—a patriotic deadline if I’ve ever seen one. Success here could open the door to more funding, more partnerships, and a whole new way of thinking about nuclear energy.
I can’t help but root for them. The idea of harnessing the Earth’s depths to power our future feels like a poetic blend of human ingenuity and nature’s strength. If they can navigate the challenges and deliver on their promise, we might be on the cusp of an energy revolution. And honestly, who wouldn’t want to see that?
This could be a turning point for clean energy, blending innovation with practicality.

As we look to a future where energy demands only grow, solutions like this could be the key to keeping the lights on without compromising the planet. What do you think—could underground reactors be the next big thing? Or is it too good to be true? One thing’s for sure: this startup is worth watching.
