Europe is experiencing a major revival of nuclear power as governments, investors, and energy companies respond to a combination of rising electricity demand, energy security concerns, and climate commitments. The rapid expansion of artificial intelligence, cloud computing, and large-scale data centers is creating unprecedented demand for reliable electricity, while geopolitical instability and decarbonization targets are encouraging policymakers to reconsider the role of nuclear energy in the continent’s future energy mix.
One of the primary drivers behind this resurgence is the growing power consumption associated with AI technologies. Modern data centers require vast amounts of continuous electricity to support computing operations, and many existing power grids are struggling to keep pace with this demand. Unlike solar and wind energy, which depend on weather conditions, nuclear power provides a constant source of low-carbon electricity capable of operating around the clock. As a result, many technology companies and energy planners increasingly view nuclear generation as a practical solution for meeting long-term electricity needs while reducing greenhouse gas emissions.
The renewed interest in the sector is also reflected in investment activity. According to market data, nuclear-sector dealmaking reached its highest level in seven years during 2025, with 25 transactions valued at approximately $1.5 billion. Momentum has accelerated even further in 2026, with ten deals announced by early June totaling around $3 billion. This surge in investment demonstrates growing confidence among financial markets that nuclear technologies will play an important role in Europe’s future energy system.
The European Commission is actively supporting this transition through significant funding initiatives. Under the 2026–2027 Euratom Research and Training Programme, the Commission is investing €330 million into nuclear-related research and development. A substantial portion of this funding is dedicated to advancing nuclear fusion technologies, which aim to produce commercial electricity through the same process that powers the Sun. Additional funding is being directed toward improving reactor safety, extending the lifespan of existing facilities, and strengthening radiation protection measures.
A key component of Europe’s strategy involves the development of Small Modular Reactors (SMRs) and Micro-Modular Reactors (MMRs). These next-generation reactors are designed to be smaller, less expensive, and faster to construct than traditional nuclear facilities. They can also be located closer to industrial facilities or data centers, reducing transmission challenges. The European Union has integrated SMR development into major policy initiatives and projects that European SMR capacity could reach as much as 53 gigawatts by 2050. To accelerate deployment, Brussels established the European Industrial Alliance on Small Modular Reactors, bringing together hundreds of stakeholders to support commercialization and regulatory coordination.
National governments are also reversing previous anti-nuclear policies. The United Kingdom has launched reforms aimed at speeding reactor approvals and selected North Wales as the site for its first SMR project. Belgium has abandoned its long-standing nuclear phase-out strategy and extended the operating lives of existing reactors. Italy is advancing legislation to reintroduce nuclear energy after decades of restrictions, while Switzerland has voted to lift its ban on constructing new reactors.
Together, these developments highlight a significant shift in European energy policy. Faced with rising electricity consumption, climate obligations, and concerns about energy independence, many governments now see nuclear power as a critical component of a secure and low-carbon energy future. As investment, innovation, and regulatory support continue to grow, nuclear power is increasingly positioned to become a central pillar of Europe’s long-term energy strategy.
