The future of nuclear
will be boring

At Deep Fission, we’re pioneering a bold new approach to delivering clean, reliable, and affordable electricity by placing our scalable 15 MW small modular reactors (SMRs) one mile underground.

The growing global demand for clean energy, accelerated by the AI boom, is challenged by power outages, climate change, and a slow transition away from fossil fuels and coal. The result has been unprecedented public support of nuclear energy –  a clean source of electricity without the carbon footprint.

Unfortunately, surface-level nuclear power plants often face unforeseen construction costs and delays due to a majority of the budget addressing containment and safety issues.

At Deep Fission, our technology team realized that by taking existing PWR technology and placing it down 30-inch boreholes a mile underground, our customers will benefit from the natural containment and safety features a mile of rock atop our small modular reactor (SMR) can provide naturally. By removing surface construction costs dramatically without sacrificing safety, we also cut the timeline to an operational power plant significantly.

Low-Cost Nuclear Energy 
A Mile Underground

Greater depth, lower risk:
Going a mile underground
removes key barriers

Natural containment
below ground

“Free” pressure underground
(160 atmospheres , 2250 psi)

No cost / safety
trade-offs

Protected from
natural disasters

Miniscule risk
of proliferation

Lower likelihood of
costly accidents

Deep Fission uses standardized pressurized water reactor (PWR) technology in a unique location deep underground. The design is a modular nuclear microreactor (each unit is 15 Megawatts-electric) that can be placed at a depth of 1 mile in a 30-inch borehole.
