Plant Restarts and Reactor Uprates
- Several reactors in the U.S. and Europe are undergoing safety upgrades and license extensions, extending their operational lifespans beyond 60 years [11].
- France’s nuclear fleet is benefiting from reactor uprates, increasing output to compensate for offshore wind and solar intermittency [11].
4. Economics: Investment and Market Trends
Capital Expenditure and Project Financing
- Nuclear power is becoming more competitive as construction costs decline and financing becomes more accessible [10].
- Private equity and tech firms (e.g., Microsoft, Google) are exploring direct investments in nuclear projects to secure long-term, carbon-free energy for AI operations [3][13].
Supply Chain and Domestic Manufacturing
- The U.S. is prioritizing domestic nuclear fuel production to reduce reliance on foreign suppliers, with DOE grants supporting fuel fabrication plants [12].
- Canada’s SMR industry is attracting foreign direct investment (FDI) from Europe and Asia, positioning it as a key exporter of next-gen nuclear technology [10].
5. Environmental Protection: Nuclear as a Clean Energy Solution
Carbon-Free Baseload Power for AI and Data Centers
- Nuclear energy is emerging as the most reliable low-carbon option for AI-driven data centers, which require 24/7 power [13].
- Deloitte’s 2025 report highlights nuclear’s role in offsetting emissions from data center growth, particularly in regions with limited renewable energy storage [13].
Waste Management and Decommissioning Innovations
- AI and robotics are being used to streamline decommissioning of old reactors, reducing costs and environmental impact [6].
- Advanced recycling technologies are being developed to reprocess nuclear waste into fuel for new reactors, improving sustainability [6].
6. Defense: Nuclear’s Role in National Security
Stockpile Maintenance and Non-Proliferation
- The U.S. National Nuclear Security Administration (NNSA)’s FY 2026 budget focuses on:
- Maintaining a safe, secure, and effective nuclear weapons stockpile [9].
- Supporting global non-proliferation efforts through IAEA inspections and technology transfer [6].
Civil-Military Nuclear Collaboration
- Dual-use technologies (e.g., advanced reactors for both power and propulsion) are being explored to strengthen defense capabilities while advancing civilian nuclear programs [1].
7. Market: Global Nuclear Capacity and Investment Outlook
