About Deep Fission

Deep Fission is a nuclear energy company pioneering underground small modular reactors. It focuses on deploying scalable 15 MWe gravity-based small modular reactors placed one mile underground to deliver carbon-free, reliable electricity. The company emphasizes faster deployment, lower surface construction costs, and modular scalability from 15 MWe to 1.5 GWe for applications including data centers, industrial facilities, and remote grids. Based on a combination of pressurized water reactor technology with LEU fuel, geothermal concepts, and deep borehole drilling, Deep Fission aims for safer, cost-efficient nuclear power with expedited regulatory progress.
