Deep Fission Receives DOE Approval for Mile‑Deep Kansas Reactor

Deep Fission has secured safety approval from the U. S. Department of Energy for its novel reactor design, which the company plans to install at the bottom of a deep hole in Kansas. The approval follows a review of the design’s safety and environmental impact. The reactor will be positioned roughly a mile below the surface, using the surrounding rock as a natural shield. The project aims to demonstrate the feasibility of deep underground nuclear reactors for clean energy production and long‑term waste storage. If successful, the technology could provide a new approach to nuclear power that reduces surface footprint and enhances containment.
