The Global Nuclear Race: Can Europe Keep Up?
How the US, China and Russia are reshaping nuclear energy — and why Europe risks falling behind
While Europe debates taxonomies and green labels, a new nuclear race is unfolding across the globe — one that increasingly resembles the space race of the twentieth century. From venture capital-backed startups in Silicon Valley to state-driven mega-projects in Asia, nuclear energy is returning not as a legacy technology, but as a strategic asset.
What is at stake is not only the future of clean electricity, but technological leadership itself. As countries compete to develop and deploy the next generation of reactors, the question facing Europe is becoming more urgent: will it lead this transformation or depend on others to power its future?
At the heart of this global revival lies a new class of technology: Small Modular Reactors (SMRs). Smaller, more flexible and potentially faster to deploy, SMRs are increasingly seen as the building blocks of a new energy system — one that combines decarbonisation with geopolitical resilience.
“The nuclear revival is not a European trend; it is a global necessity. Countries that master this technology will control their own energy future.”

His warning underscores the scale of the shift. Nuclear energy is no longer a domestic policy choice — it is becoming a defining factor in global power dynamics.
The United States: Innovation Meets Capital
In the United States, nuclear energy is increasingly treated as a frontier technology — not unlike artificial intelligence or space exploration. A new generation of companies is rethinking reactor design, supported by a combination of federal funding and private investment.
Entrepreneurs and investors are betting that nuclear power can be transformed into a scalable, commercially viable product. This shift is particularly visible in the ecosystem surrounding advanced reactor startups, where the logic of Silicon Valley — rapid iteration, venture capital and technological disruption — is beginning to shape an industry long dominated by governments.
“The next generation of nuclear energy will not come only from governments, but from venture-backed innovation. We are approaching nuclear like software: faster, smaller and scalable.”

The American model reflects a broader strategic ambition: to position the United States as the leading exporter of next-generation nuclear technology, particularly to allied nations seeking alternatives to Russian or Chinese systems.
China: Scale and Execution
If the United States represents innovation, China represents execution.
Beijing is building more nuclear reactors than any other country, often within tight timelines and controlled budgets. Through centralized planning and standardized designs, China has developed an industrial approach that prioritises speed, repetition and learning-by-doing.
“The Chinese advantage is not just capital, but repetition. By building multiple reactors simultaneously, they create a learning curve the rest of the world can barely match.”.

This model allows China to rapidly reduce costs and scale production — precisely the dynamic that SMRs are intended to unlock.
For European policymakers, the parallel with the solar industry is hard to ignore: technologies pioneered in the West, industrialised at scale in China.
Russia: Nuclear Power as Geopolitical Leverage
Russia remains one of the most influential players in the global nuclear market, primarily through its state-owned company Rosatom.
Unlike many Western competitors, Russia offers a comprehensive package: reactor design, construction, fuel supply and long-term financing. These agreements often span decades, creating deep and lasting ties between supplier and customer.
“Russia uses nuclear energy not just as an export product, but as a diplomatic anchor. A contract with Rosatom is effectively a century-long relationship.”.

In this sense, nuclear energy becomes a tool of geopolitical influence — embedding long-term dependencies that extend far beyond electricity generation.
Europe: Fragmented but Awakening
Against this backdrop, Europe’s position appears both promising and precarious.
The continent possesses deep technological expertise, a strong industrial base and decades of experience in nuclear engineering. Yet its efforts are often fragmented across national borders, with differing political views on the role of nuclear energy.
To address this challenge, the European Commission has launched initiatives aimed at coordinating industrial and regulatory efforts, most notably the European SMR Industrial Alliance.
“Europe cannot afford to become a marketplace for other people’s technology. If we fail to standardise and coordinate now, we will import our energy sovereignty in the future.”.

The alliance seeks to align industry players, develop common standards and build a European supply chain capable of competing globally.
The Battle for Standards and Supply Chains
Beyond the reactors themselves lies a deeper contest — one over standards, certification and supply chains.
Who defines the safety requirements for SMRs? Which technologies become the global norm? Who controls the production of nuclear fuel and critical components?
These questions will determine not only who builds reactors, but who shapes the rules of the global energy system.
In this emerging landscape, technological leadership translates directly into economic and geopolitical power.
The Strategic Risk
For Europe, the greatest risk is not technological failure, but strategic hesitation.
The continent has already experienced the consequences of losing industrial leadership in key clean technologies. In the solar sector, European innovation was eventually overtaken by large-scale manufacturing elsewhere.
The same pattern could repeat in nuclear energy.
If SMR development remains fragmented and underfunded, Europe may find itself importing reactors designed and built abroad — along with the dependencies that come with them.
A Defining Moment
The global nuclear race is no longer a distant prospect; it is already underway.
As the United States accelerates innovation, China scales production and Russia expands its geopolitical footprint, Europe faces a narrowing window of opportunity.
In a world where energy systems underpin economic strength and political autonomy, the stakes could hardly be higher.
The nuclear comeback is real. The question now is who will define it — and who will follow.
