Davos 2026: IAEA Director General highlights alliance between Nuclear Energy and AI at WEF

The Director General of the International Atomic Energy Agency (IAEA), Rafael Mariano Grossi, has underscored the growing interdependence between artificial intelligence and nuclear energy, describing the relationship as a “structural alliance” essential to meeting the world’s rising demand for clean and reliable power.

Speaking at the World Economic Forum 2026, Grossi noted that artificial intelligence is driving a surge in global electricity consumption, particularly through data centres, which already use more than 400 terawatt-hours of electricity annually. He emphasized that nuclear energy is uniquely positioned to provide the scale, reliability and low-carbon power required to support AI-driven digital infrastructure.

Grossi explained that as AI systems increasingly power applications across industries, they require uninterrupted electricity supply, a requirement that nuclear energy can meet more effectively than many alternative sources. He warned that failure to align energy planning with AI growth risks increased reliance on less sustainable power options.

At the same time, Grossi highlighted how artificial intelligence is strengthening the nuclear sector itself. According to him, AI technologies are being applied to improve reactor operations, enhance design efficiency, support safeguards and reinforce security measures, including through advanced anomaly detection and satellite image analysis. He added that extending the operational life of existing reactors and deploying new technologies such as small modular reactors will be critical to meeting future energy needs.

Grossi also outlined the role of the IAEA in supporting countries during this transition by setting international standards, sharing technical expertise and facilitating collaboration among governments, industry and financial institutions. He stressed that effective coordination is essential to ensure that growing energy demand is met through clean, stable and secure power systems.

The discussion took place during a high-level exchange at WEF 2026, bringing together global experts from the energy, technology and policy communities to examine the intersection of AI development and sustainable energy infrastructure.
