Deep Fission, an advanced nuclear energy company, secured $30 million in a private placement offering. This significant Deep Fission nuclear funding also facilitated a go-public reverse merger with Surfside Acquisition Inc., now renamed Deep Fission, Inc. Investors included 8VC, Deep Future, Wave Function, Ed Eisler of EE Holdings, and Mark Tompkins of Montrose Capital Partners.
Advancing Underground Nuclear Technology
Deep Fission develops small modular pressurized water reactors, placing them one mile underground. This unique approach leverages natural geology for shielding, thus reducing surface footprint and enhancing security. The company targets deployment of its first underground reactor in 2026.
The company's patent-pending Borehole Reactor integrates established nuclear, drilling, and geothermal technologies. Consequently, this design dramatically reduces construction time and expense. Deep Fission aims for a levelized cost of electricity between 5-7 cents per kWh for its initial commercial project.
Deep Fission was selected for the Department of Energy’s Reactor Pilot Program. This program targets reactor criticality by July 2026.
This Deep Fission nuclear funding will support building the pilot reactor. The company plans rapid commercialization, addressing energy demand from AI data centers and other global customers. Competitors in the advanced nuclear space include TerraPower and NuScale Power.
