The concept of burying nuclear reactors underground might seem like a scene from a sci-fi movie, but it's becoming a reality thanks to innovative startups like Deep Fission. In a world grappling with escalating energy demands, especially from data centers powering AI technologies, traditional energy sources are being pushed to their limits. As a response, the nuclear sector is undergoing a renaissance, with companies exploring groundbreaking ways to generate clean and efficient power. Deep Fission, in collaboration with data center developer Endeavour, aims to harness subterranean nuclear power to meet these demands. But how exactly does this approach work, and what implications does it have for the future of energy? The Rise of Subterranean Nuclear Power
The 1950s marked the beginning of underground nuclear testing as countries sought to minimize fallout from aboveground detonations. Fast forward to today, and this concept of using the earth as a natural barrier is being revisited by Deep Fission. By lowering small modular reactors into one-mile-deep boreholes, the company aims to utilize the insulating properties of the earth to safeguard its operations. This method not only promises enhanced safety but could also reduce the need for the tons of concrete traditionally required for reactor construction.
Deep Fission's partnership with Endeavour signals a significant step toward realizing this vision, with plans to generate 2 gigawatts of subterranean nuclear power. The startup's innovative approach aligns with the growing trend among nuclear companies to develop compact reactors that can be mass-produced, subsequently lowering costs and increasing accessibility. The collaboration also underscores a broader effort within the tech industry to secure reliable and sustainable energy sources to fuel the ever-increasing computational power required by AI technologies.

Strategic partnerships are at the core of Deep Fission's approach, as demonstrated by its recent deal with Endeavour. Although the financial terms of the agreement remain undisclosed, it highlights the trust and confidence stakeholders have in the startup's vision. The partnership is part of a broader trend where tech giants like Google and Amazon are turning to nuclear startups to meet their energy needs. For instance, Google has teamed up with Kairos for 500 megawatts of reactors, while Amazon collaborates with X-Energy for around 300 megawatts.
These alliances emphasize the importance of sustainable and efficient energy solutions in the tech industry. As data centers continue to expand globally, their energy consumption increases, necessitating innovative solutions like those offered by Deep Fission. Such partnerships not only showcase the potential of nuclear power in a modern context but also highlight the critical role of investment in driving technological advancements and sustainability efforts.

At the heart of Deep Fission's strategy is the use of small modular reactors (SMRs). These reactors offer numerous advantages over traditional nuclear power plants, primarily due to their compact size and modular design. By utilizing mass production techniques, SMRs promise to significantly reduce the cost of nuclear power, making it a more viable option for widespread adoption. Their smaller footprint also allows for easier integration into existing infrastructure, maximizing land use efficiency.
Deep Fission's reactors employ pressurized-water designs, a reliable technology used in various applications, from nuclear submarines to large-scale power plants. This approach highlights the adaptability and versatility of SMRs, making them suitable for a wide range of energy needs. The ability to generate power at a cost of five to seven cents per kilowatt-hour positions Deep Fission as a competitive player in the energy market, with the potential to revolutionize how we think about nuclear power.

Despite the promising prospects of subterranean nuclear power, regulatory approval remains a significant hurdle for startups like Deep Fission. The company began the licensing process with the Nuclear Regulatory Commission (NRC) in March, facing a timeline that, historically, could span several years. However, recent changes in legislation have introduced an 18-month limit for the NRC to approve or reject small modular reactors, expediting the process and providing a clearer path for innovation.
As Deep Fission targets operational status for its first reactor by 2029, it joins a wave of companies poised to transform the nuclear landscape in the U.S. While the path to regulatory approval is fraught with challenges, the potential benefits of this technology are undeniable. As the world continues to seek sustainable and efficient energy solutions, could subterranean nuclear power be the breakthrough we've been waiting for?
