Deep Underground Nuclear Reactors Planned
11 Jul
Summary
- Deep Fission is developing underground modular reactors.
- Reactors will be placed one mile beneath the surface.
- Geological formations will provide shielding and containment.
Deep Fission, Inc. is advancing a novel approach to nuclear energy with its Gravity Reactor. This small modular reactor is based on established pressurized water reactor technology but features a unique emplacement strategy: one mile underground in deep boreholes.
The company's activities encompass crucial stages of development, including test borehole construction, detailed reactor design, comprehensive safety analysis, and thermal-hydraulic modeling. Regulatory engagement with both the Department of Energy (DOE) and the Nuclear Regulatory Commission (NRC) is a key focus, alongside building a robust supply chain for necessary components and drilling operations.
This innovative design utilizes subsurface conditions to enhance safety and efficiency. The surrounding geological formation will provide structural confinement and shielding, while hydrostatic pressure from a water column within the borehole will support the reactor's operating pressure and cooling systems. This approach aims to leverage the Earth itself as a key component of the reactor's containment and operational framework.
