Deep Fission is an advanced nuclear energy company developing a novel deployment architecture called Gravity™ that integrates established technologies — pressurized water reactors, geothermal energy-transfer components, and deep borehole drilling — to place reactor systems a mile underground. The design uses hydrostatic pressure from a deep water column to support operating pressure and cooling, applies geothermal-style surface energy transfer to turbines, and aims for rapid, low-footprint deployments (a stated 6-month target for a single reactor deployment and a 2027–2028 commercial operation goal). The company reports an 18. 5 GW commercial pipeline via letters of intent with power-site partners, has moved prototype hardware (reactor canister) to a Kansas site, and is engaging with regulators and investors through public filings and offerings.
