Deep Fission

Deep Fission is an advanced nuclear energy company developing small modular pressurized water reactors designed for deployment approximately one mile underground. Its Gravity Nuclear Reactor combines established PWR technology with deep borehole drilling and geothermal heat-transfer methods. Each reactor is designed to produce up to 15 MWe using conventional low-enriched uranium fuel, with multiple boreholes enabling larger generation sites. The company is advancing its first reactor project in Parsons, Kansas through the U.S. Department of Energy Reactor Pilot Program. Its strategic focus centers on modular nuclear generation for data centers, industrial facilities, utilities, and remote or military sites.
