Powering Humanity from a Mile Underground
Deep Fission is revolutionizing the energy landscape with innovative technology that places a small modular pressurized water reactor in a borehole approximately one mile underground. Our approach combines established pressurized water reactor technology with a novel underground deployment model designed to simplify construction, enhance safety, and support rapid, scalable commercial deployment.
Energy Resilience for the AI Era
We’re working to expand access to reliable energy through a new approach to proven technology.
Our team brings decades of operational and regulatory experience to focus on simplifying infrastructure, reducing deployment bottlenecks, and advancing a path toward scalable nuclear energy.
Origin Story
Deep Fission was founded in 2023 by father-daughter team Liz and Rich Muller, to address the growing gap between rising energy demand and the pace at which reliable, low-carbon power can be deployed. We are currently advancing the development of our first site in Parsons, Kansas and were selected for the Department of Energy’s Reactor Pilot Program.
Build With Us
Powered by a team of experienced scientists, engineers, and entrepreneurs, Deep Fission is focused on delivering reliable, low-carbon baseload power to meet growing electricity demand from utilities, industrial customers, and data centers. Together, we are advancing a phased, disciplined commercialization plan grounded in regulatory engagement, operational credibility, and deployment at infrastructure scale.
