The deal is the latest in a flurry of agreements that, if completed, would usher in a nuclear power renaissance in the U.S. Deep Fission’s plan is to switch on its first reactor in 2029, which is in line with other companies’ plans.

Deep Fission, a California nuclear startup, is working with a data center developer to build small nuclear reactors a mile underground.

Offering a unique approach to powering data centers through nuclear energy, Deep Fission and Endeavour Energy have announced a strategic partnership. Their agreement plans to bury small modular reactors (SMRs) a mile underground.

The Deep Fission Borehole Reactor 1 (DFBR-1) is a pressurized water reactor (PWR) that produces 15MWt (thermal) and 5MWe (electric) and has an estimated fuel cycle of between ten to 20 years.

Deep Fission aims to eliminate the need for costly concrete and steel surface containment buildings by placing its reactor a mile underground.
