Small modular reactor market was valued at $6.2 billion in 2025 and is projected to reach $23.2 billion by 2035, growing at a CAGR of 14.2% during the forecast Period (2026-2035). The market is witnessing steady growth, driven by increasing demand for safe, flexible, and low-carbon energy solutions. SMRs offer advantages such as modular construction, reduced capital costs, and the ability to serve remote or small-scale power requirements. Key applications include power generation, desalination, industrial process heat, and research. The market is segmented by reactor type, power capacity, application, end-user, and deployment system. Ongoing technological advancements, supportive government policies, and rising energy security concerns are expected to propel market expansion.
Growing Demand for Clean, Low-Carbon Energy
One of the primary drivers of the SMR market is the increasing global focus on reducing greenhouse gas emissions and meeting climate change mitigation targets. Countries worldwide are committing to net-zero goals and looking for reliable, low-carbon power generation solutions that can complement renewable energy sources such as solar and wind. SMRs, with their smaller size, modular design, and inherently lower emissions than fossil-fuel-based generation, are positioned as an attractive alternative to support decarbonization efforts while providing steady baseload power.
Energy Security, Reliability, and Electrification Needs
Another major market driver is the global push for enhanced energy security and a reliable electricity supply. As economic activity and electricity consumption grow, particularly in emerging and fast-developing economies, there is increasing demand for dependable power infrastructure that is less vulnerable to supply disruptions. SMRs offer scalable and resilient energy solutions that are well-suited for remote locations, grid-isolated regions, and industrial clusters where traditional large power plants may not be feasible. Their ability to provide continuous, dispatchable power also helps balance intermittency from renewables, bolstering grid stability and reliability.
Government Support, Policy Incentives, and Technological Advancements
Strong governmental backing and policy frameworks are actively encouraging SMR development and commercialization. Many nations have established supportive regulatory environments, funding programs, and nuclear energy strategies that include SMRs as part of future energy mixes. This includes financial incentives, public-private partnerships, research and development support, and streamlining of licensing processes, all of which reduce investment risk and accelerate deployment timelines. Alongside this, ongoing technological improvements in modular construction, passive safety systems, and digital control technologies are making SMRs more efficient, safer, and more commercially viable.
Market Segmentation
Pressurized Water Reactor (PWR) Segment to Grow at a Considerable Market Share
Pressurized water reactor (PWR) category is expected to lead the Global Small Modular Reactor (SMR) Market and remain the largest segment over the forecast period. This dominance is primarily driven by the technological maturity, proven safety record, and regulatory familiarity of PWR technology compared to other advanced reactor types. PWR-based SMRs leverage decades of operational experience from conventional large nuclear reactors, making them more acceptable to regulators, utilities, and investors. Many leading SMR developers are prioritizing PWR designs because they integrate passive safety systems, a simplified reactor architecture, and modular construction, thereby reducing construction risk and improving project bankability.
Additionally, PWR SMRs are well-suited for grid-connected power generation, the largest application area globally, and can be deployed as single-module or multi-module systems depending on demand. Their compatibility with existing nuclear supply chains, fuel infrastructure, and workforce skills further accelerates commercialization. Governments in North America, Europe, and parts of Asia-Pacific are also supporting PWR-based SMRs through funding programs and licensing frameworks, reinforcing their market leadership. As a result, PWR SMRs are expected to capture the largest share of global installations, investments, and near-term deployments, positioning this segment as the primary growth driver across the overall SMR market.
Power Generation: A Key Segment in Market Growth
Power generation application segment is the single most influential driver of growth in the global Small Modular Reactor (SMR) market. SMRs are increasingly being positioned as a reliable source of low-carbon baseload electricity, addressing the limitations of intermittent renewable energy sources such as wind and solar. Their ability to deliver continuous, stable power with a significantly smaller physical footprint makes them highly attractive for national grids, remote regions, and areas with constrained infrastructure. Unlike large nuclear reactors, SMRs enable phased capacity additions, allowing utilities and governments to align investments with demand growth while reducing upfront capital risk. This flexibility is particularly valuable for emerging economies and regions seeking to enhance energy security without committing to large, centralized nuclear projects.
In addition, SMRs are well-suited for replacing aging coal and gas-fired power plants, supporting decarbonization targets while maintaining grid stability. Growing electricity demand from urbanization, electrification of transport, and energy-intensive sectors such as data centers further strengthens the role of SMRs in power generation. As regulatory frameworks mature and demonstration projects move closer to commercialization, power generation remains the primary application accelerating SMR deployment globally, making it the most critical segment shaping overall market expansion.
The global small modular reactor market is further divided by geography, including North America (the US and Canada), Asia-Pacific (India, China, Japan, South Korea, Australia and New Zealand, ASEAN Countries, and the Rest of Asia-Pacific), Europe (the UK, Germany, France, Italy, Spain, Russia, and the Rest of Europe), and the Rest of the World (the Middle East & Africa, and Latin America).
North America Region to Hold a Substantial Growth Rate
In North America, the US dominates the global small modular reactor market, holding a major share due to its advanced technological infrastructure, strong government support, and well-established nuclear energy ecosystem. The country has been at the forefront of nuclear innovation, with multiple companies actively developing next-generation SMRs that emphasize safety, modularity, and efficiency. Government initiatives, including funding programs and regulatory frameworks, have accelerated research, development, and commercialization of SMR technologies, enabling faster deployment compared to other regions. The US benefits from a combination of robust private sector investment and public-private partnerships, which have attracted significant capital into the sector, facilitating prototype development and pilot projects.
Additionally, the demand for clean, reliable, and flexible energy solutions across various states has further strengthened the adoption of SMRs in the country. With a growing emphasis on reducing carbon emissions and replacing aging nuclear infrastructure, the US market is expected to continue leading globally, setting technological benchmarks and influencing regulatory standards. The dominance of the US in the SMR market is further reinforced by its access to skilled labor, advanced supply chains, and collaborations with international stakeholders, all of which support the expansion of commercial-scale SMR deployment. This leadership positions the US as a pivotal driver of growth and innovation in the global SMR landscape.
The major companies operating in the global small modular reactor market include NuScale Power, LLC, Rolls-Royce SMR, TerraPower, Westinghouse Electric Co., X-Energy, among others. Market players are leveraging partnerships, collaborations, mergers, and acquisitions to expand their businesses and develop innovative products to maintain their market positioning.
