Episode notes
Deep Fission Origin
- A customer asked Deep Isolation to analyze a scenario where fresh nuclear fuel was accidentally placed underground.
- This led to the realization that deep boreholes offer ideal conditions for nuclear reactors.
Cost Savings of Underground Reactors
- Traditional nuclear plants' high construction costs, about 80% of the total, are driven by pressure and containment needs.
- Deep boreholes naturally provide both containment and pressure, potentially reducing costs.
Modular Design
- Deep Fission uses an array of small, modular reactors placed in separate boreholes.
- Each borehole generates 15 megawatts of electricity, scalable for larger energy needs.
