Drive out to the edge of Parsons, Kansas, and you will find an overgrown industrial park dotted with old munitions bunkers. You will also find something else. A hole drilled a mile deep into billion-year-old pink-flecked granite.
This quiet farming town of 9,600 people is caught in the middle of a high-stakes energy experiment. A California startup called Deep Fission wants to build the world's first commercial underground nuclear reactor right here. Not everyone is popping champagne.
Town meetings are packed. Neighbors are shouting. Some residents see a golden ticket for economic survival. Others see an unproven nuclear hazard buried beneath their drinking water.
The Gravity Reactor Concept
Let us look at what Deep Fission is actually building. Traditional nuclear plants require massive, billion-dollar containment structures and complex cooling systems to prevent disaster. Deep Fission wants to flip that script.
They call it a Gravity Reactor. The core idea is simple. You drop a 30-inch wide canister loaded with nuclear fuel down a borehole one mile deep.
At that depth, the natural pressure of the earth and the surrounding rock act as natural safety barriers. The water down there heats up, and the steam travels back to the surface to spin a turbine and generate electricity. Each of these micro-reactors is designed to churn out about 15 megawatts. That is enough juice to power roughly 12,000 homes.
Founder Liz Muller and her father, nuclear physicist Richard Muller, have raised around $150 million to push this technology forward. Roughly $40 million of that funding is earmarked directly for the Parsons site. They have already drilled test holes, and a full-scale prototype canister is waiting to test installation workflows. They want to start generating electricity by late 2027 or 2028.
That timeline terrifies traditionalists. Nuclear projects usually crawl along over decades. Deep Fission is sprinting.
Why Parsons is Deeply Divided
Small towns across the Midwest are fading. Manufacturing jobs left decades ago. Young people move away. Parsons is no exception.
Local leaders are desperate for a spark. Police Chief Robert Spinks voiced what many supporters feel, noting that if this proven technology in a new format brings in manufacturing and living-wage jobs, it is a massive win. The local economy needs a heartbeat, and tech companies hunting for carbon-free power to feed data centers might just look at Kansas if cheap nuclear energy is plugged in.
Then you talk to homeowners.
Jerel Johnson put $125,000 into his house expecting a quiet retirement. Instead, he gets an experimental nuclear borehole down the road. He calls it one of the worst ideas he has ever heard.
Activist groups like the Prairie Dog Alliance are mobilizing. Marjorie Reynolds, a pediatric nurse leading local pushback, points out the obvious flaw from her perspective: nobody voted for this. If something goes wrong with high-level nuclear waste a mile down, residents live with the contamination forever.
The Regulatory Fast Lane
Deep Fission is benefiting from a broader political push. The federal government wants to quadruple American nuclear capacity by 2050.
The Department of Energy included this project in a pilot program designed to accelerate advanced nuclear tech. Rules are being streamlined. Environmental reviews are being fast-tracked.
Critics argue the government is cutting corners on safety to beat global competitors in the clean energy race. A coalition of state attorneys general has already pushed back against sweeping federal exemptions for advanced nuclear test sites, arguing that local communities deserve rigorous, peer-reviewed environmental impact statements rather than rushed approvals.
Deep Fission insists the reactor sits far below local aquifers and poses zero threat to groundwater. They promise strict adherence to both nuclear and oil-and-gas drilling standards.
Whether this underground gamble turns Parsons into an economic powerhouse or a cautionary tale depends entirely on a mile of Kansas granite holding tight under pressure. The drills are spinning, and the town is holding its breath.
