Investment Proposal: $100 Billion Commitment to Thorium-Based Molten Salt Reactors for U.S. AI and Data Center Infrastructure
Executive Summary
This proposal outlines a $100 billion investment, with a 20% contingency ($20 billion) for a total of $120 billion, to develop and deploy thorium-based molten salt reactor (MSR) technology to meet the surging energy demands of U.S. AI and data centers, projected to grow from 35 GW in 2024 to 78 GW by 2035. Using a hybrid model of in-house R&D and strategic partnerships, the initiative leverages government grants, tax incentives, and economic benefits to achieve self-sustainability within 10-12 years, delivering an optimized average annual ROI of 10.5% and a payback period of 8 years, with a 20-year net profit of $245.67 billion. Thorium MSRs offer superior safety, reduced waste, and cost efficiencies compared to small modular reactors (SMRs) and traditional nuclear technologies, ensuring energy security, environmental benefits, and a competitive edge for the U.S. in global clean energy innovation.
Introduction: The Need for Thorium MSRs
The U.S. faces unprecedented energy demands driven by AI and data centers, with electricity consumption expected to rise from 4,193 billion kWh in 2025 to over 5,900 billion kWh by 2045. Data centers alone are projected to require an additional 323 TWh by 2030, straining an aging grid needing $1.4 trillion in upgrades. Renewables like solar and wind lack the baseload reliability required for 24/7 AI operations. Thorium MSRs provide a solution with abundant fuel, high efficiency, and modular designs ideal for co-location with data centers. Without investment, the U.S. risks falling behind global leaders advancing similar technologies, jeopardizing energy security and technological dominance.
