The Future
of Nuclear

The future of American energy is carbon free while remaining economically accessible. The future of American energy is nuclear energy.

Deep Fission turns this envisioned future into a reality with affordable, modular, reliable nuclear power using traditional technology in an untraditional environment: deep underground.

At Deep Fission, we recognize that while nuclear energy is a needed part of the American energy future, its safety and cost history is complicated. That is why we are developing the first modular advanced nuclear reactor to be placed one mile underground. The inherent enhanced safety blanket of 10 billion tons of natural rock containing our reactor protects the public and significantly cuts the construction costs. Most importantly, Deep Fission brings affordable, reliable energy to American homeowners, data centers, and industrial partners faster than ever before.
