🗞️ Driving the news: A California-based nuclear startup, Deep Fission, is proposing a radical new approach to clean energy: burying nuclear reactors one mile underground
• The concept, developed by CEO Elizabeth Muller, involves placing small reactors deep within boreholes and flooding them with water
• This method could dramatically lower costs, simplify safety, and manage nuclear waste more efficiently
🔭 The context: Traditional nuclear reactors are large, expensive, and require extensive safety infrastructure
• Deep Fission’s concept builds on the increasing interest in small modular reactors (SMRs), with the added innovation of deep geological installation
• By leveraging existing drilling technology from the oil and gas industry, the firm aims to bypass above-ground risks and permit hurdles, offering a potentially faster and more affordable deployment model
🌍 Why it matters for the planet: If successful, Deep Fission’s model could help revive nuclear power as a viable clean energy source, especially in hard-to-decarbonise sectors
• Subsurface deployment mitigates many public concerns around radiation and accidents, while reducing land use and operational emissions
• It could also simplify waste containment by keeping radioactive material isolated at depth. However, long-term geotechnical risks and regulatory challenges remain to be addressed
⏭️ What's next: Deep Fission plans to test a prototype reactor within the next few years, likely in a geologically stable desert region in the U.S. If successful, it could attract government and private investment, with potential for global deployment
• The firm must navigate nuclear regulatory frameworks and demonstrate consistent performance under deep-earth conditions — a crucial step before commercial scale-up
💬 One quote: “This could fundamentally change how we think about nuclear power — making it safer, cleaner, and cheaper,” — Elizabeth Muller, CEO of Deep Fission
📈 One stat: The U.S. Department of Energy estimates that advanced reactors like SMRs could reduce nuclear construction costs by up to 60%, a figure potentially increased further by Deep Fission’s underground model
