Deep Fission takes advantage of the unique combination of pressurized water reactor technology, including an existing regulatory path and supply chain, and a mile deep environment consisting of deep boreholes. For more information, view our solutions page.

Deep Fission is actively engaged with the NRC, which you can learn more about on our regulatory page. We are confirming our first sites and customers now, and expect to have our first commercial reactors in operation within 3 years of final site confirmation.
