In brief
On 10 March 2026, the European Commission officially published the long-awaited Strategy for the development and deployment of Small Modular Reactors (SMRs) in Europe. The document presents a strong case for the deployment of SMRs as a necessary step for the EU. Its primary focus is on accelerating the development and deployment of SMRs in Europe over the coming decade by promoting a joint commitment to the pursuit of such goal on the part of EU institutions, Member States, industry, and research organizations with the backing of broad public acceptance. The initiative calls for intensive cooperation to harness the potential of SMRs for realizing a sustainable, competitive, and resilient energy future for Europe. SMRs represent a significant opportunity to rapidly advance decarbonization without undermining competitiveness.
Key takeaways
- The deployment of SMRs in Europe by the 2030s will be crucial for the continent's competitiveness, and a robust policy framework is essential to support innovation and ensure the necessary conditions for the rapid deployment of SMRs in the EU.
- SMR as a joint European industrial project: The EU’s strategy treats SMR technologies as a joint industrial project of strategic importance requiring close cooperation. A consolidated European approach is seen as essential to shorten time‑to‑market, achieve production scale, and ensure long‑term cost competitiveness.
- Diverse end uses: SMRs can be used in many end applications, to produce electricity and heat for energy-intensive industries, district heating systems, and infrastructure with high and stable energy demand. With their ability to operate in hybrid systems and off‑grid, SMRs can help relieve pressure on power grids, which are coming under increasing strain due to rising demand from data centers, low‑carbon hydrogen and synthetic‑fuel production as well as water desalination. They can play a particularly important role in hard-to-abate sectors such as district heating, which currently relies heavily on fossil fuels, chemicals, steel, refineries, maritime transport and defense. Microreactors can be used for local applications such as ports, airports, industrial plants, mining sites and power defense or in disaster relief operations.
- Increased autonomy and energy security: SMRs can strengthen the EU’s energy security by reducing dependence on fossil fuels and complementing renewables. Within the broader SMR landscape, which is still evolving, Advanced Modular Reactors (AMRs) represent next‑generation (Generation IV) designs that use innovative coolants and fuel types. Their deployment can stimulate specialized employment in local communities, while lower waste volumes may help increase public confidence in nuclear technologies.
- Conditions for successful SMR implementation in Europe: Successful SMR deployment in Europe requires the rapid commissioning of first-of-a-kind (FOAK) SMR installations as soon as possible and not later than the early 2030s, alongside continued work on advanced AMR technologies. Of equal importance are a strong European supply chain and a fleet‑based approach facilitating serial production. These efforts should be supported by streamlined regulatory processes and closer cooperation between national regulators to accelerate licensing and to achieve economies of scale.
- Establishing a European supply chain for modular and series production: A competitive EU supply chain must be established to ensure high local content and European added value in SMR projects. Support for achieving this objective is to come from the Commission’s Industrial Accelerator Act proposal. Developing modular manufacturing capacity in Europe will be critical for facilitating series production and shortening construction times, enabled by modular designs and a diverse supplier base. Deploying a fleet of SMRs with a consistent design across multiple countries will also require industrial standardization and regulatory cooperation in the field of licensing.
- Industrial cooperation and project consolidation: Small nuclear reactor developers, utilities, potential end users, and companies in the supply chain, including small and medium-sized enterprises, must work closely together to stimulate strong market demand, to develop the necessary supply chain and to create compelling business cases for small nuclear reactors.
- Financing the development of the SMR value chain: The Commission plans an additional temporary InvestEU top‑up of EUR 200 million by 2028 with the goal of accelerating the deployment of initial commercial units of innovative nuclear technologies, including SMRs and AMRs. The Scaleup Europe Fund will provide further capital for high‑potential European companies developing these technologies. When creating Net‑Zero Acceleration Valleys, Member States and regions are encouraged to assess whether SMRs could supply power or heat and, where relevant, establish the necessary supporting framework.
- Proposed actions for Member States: Member States should streamline intra‑EU administrative procedures for SMR‑related export controls and work with the Commission to safeguard European IP. They are encouraged to form an "SMR" coalition to coordinate policy, regulatory and licensing approaches, including the possible alignment or mutual recognition of licensing decisions. Together with the Commission, they should support joint safety assessments and develop regulatory sandboxes, moving quickly to facilitate initial SMR deployment in the early 2030s and lay the groundwork for a fleet‑based rollout.
Background
SMRs are emerging as a major industrial development opportunity for Europe, with the potential to mobilize value chains across engineering, advanced materials, robotics, and finance. They are expected to complement high‑power nuclear reactors by providing flexible, safe, and efficient clean energy and decarbonized heat for industry and households. Their size, modularity, and nuclear attributes make them relevant for all Member States, with estimated EU capacity of 17–53 GWe by 2050.
At the same time, decarbonization pressures in sectors such as chemicals, district heating, and data centres are intensifying. SMRs could play a significant role in meeting those needs. Locating SMRs near industrial clusters or in hybrid/off‑grid configurations may also reduce pressure on existing grid infrastructure.
To realize this potential, SMRs must be developed as a joint European industrial project based on close cooperation in research, supply chain development, licensing, skills, and financing. A consolidated EU approach is essential to shorten time‑to‑market, scale production, ensure competitiveness, and secure manufacturing capacity for both EU and export markets. Coordinated action between Member States and trusted global partners will be necessary to deploy SMRs at scale within an ambitious timeframe.
Conclusions
The first SMR units could be operational by the early 2030s, but success will depend on coordinated action by EU institutions, Member States, industry, and the research community, along with societal engagement. Given the extremely dynamic and unstable global situation, which directly affects traditional supply chains including those for fossil fuels, developing European competences in the rapid deployment of small nuclear capabilities seems like a must-have solution. Ongoing transformation to a zero-emission economy combined with the rapid development of new types of energy consumers (data centers) as a result of the expansion of artificial intelligence represent a unique opportunity for those entities that can be the first to offer scalable and cost-effective solutions ensuring security of supply for clean energy in the form of SMRs and AMRs.
