Integrating Three Established Technologies
An approach that enables the use of off-the-shelf components, existing supply chains, and readily available low-enriched uranium (LEU) fuel.
Gravity Well Drilling Oil & Gas
Developing advanced deep borehole drilling using standard infrastructure for containment one mile underground.
Heat Exchanger Geothermal
Novel deployment approach applies proven geothermal components and processes for energy transfer to the turbine generator at the surface.
Reactor Canister PWR
Hydrostatic pressure from one-mile-deep column of water provides 160 atm of reliable pressure, safely and naturally.
Existing LEU Fuel Supply
Deep Fission is designed to use readily available low-enriched uranium (LEU) fuel — the same category of fuel used in commercial nuclear power plants today.
