Deep Fission Expands Customer Pipeline to 12.5 Gigawatts

BERKELEY, Calif.--(BUSINESS WIRE)--Deep Fission, Inc. (“Deep Fission” or the “Company”), a pioneering advanced nuclear energy company placing small modular pressurized water reactors in boreholes one mile underground, announced today it has signed Letters of Intent (LOIs) with data centers, co-developers, industrial parks, and strategic partners totaling 12.5 gigawatts (GW) of power. The LOIs outline plans to pursue commercial deployment of Deep Fission’s small modular reactors (SMRs).

“The world is transforming before our eyes, and there is a race to secure the energy needed to fuel the robust growth in AI and data centers,” said Liz Muller, Co-Founder and CEO. “It’s inspiring to see the swift embrace of Deep Fission’s technology. We’re proud to partner with industry leaders as we seek to deliver safe, cost-effective, and rapidly deployable power that meets today’s demand while building a more resilient future.”

Deep Fission’s proprietary design combines proven methods from the nuclear, oil and gas, and geothermal industries, while utilizing off-the-shelf parts and readily available, low-enriched uranium (LEU) to simplify supply chains. Each reactor will be placed one mile underground, where the surrounding geology offers billions of tons of passive shielding and natural containment. This approach aims to enhance safety and security, reduce surface footprint, and enable a faster, more affordable path to deployment.

The Company estimates its model could reduce overall costs by 70–80% compared to traditional nuclear plants, delivering a projected levelized cost of electricity (LCOE) of 5–7 cents per kWh.

The news follows Deep Fission’s successful completion of a go-public transaction and private placement financing that raised $30M. The Company will apply to have its shares quoted on the OTCQB (The Venture Market), and recently announced its first planned sites in Texas, Utah, and Kansas.
