Small Modular Reactor Market

Small Modular Reactor MarketSmall Modular Reactor Market is anticipated to expand from $6.8 billion in 2025 to $10.1 billion by 2035, growing at a CAGR of approximately 3.9%. The small modular reactor (SMR) market is highly competitive and segmented into top-tier, mid-tier, and low-tier players based on technology, innovation, and cost efficiency. Key players in the SMR market are a mix of established nuclear energy companies and newer startups, with competition being particularly fierce in terms of technological innovation, regulatory approvals, and financing capabilities. Leading companies, such as NuScale Power, Rolls-Royce, and X-energy, have emerged as frontrunners due to their strong R&D pipelines, strategic partnerships, and governmental support. NuScale Power's SMR design is among the most advanced, with a strong focus on safety, scalability, and efficiency. Rolls-Royce has positioned itself as a major player in the UK and European markets, emphasizing cost reduction and modularity for quick deployment.

While the technical aspects of SMRs remain a competitive battleground, regulatory approval is another area of intense competition. Different countries have varying timelines and requirements for licensing SMRs, and securing government-backed incentives and support is critical. The competition also extends to securing funding, as SMRs are capital-intensive technologies that require strong financial backing to make it from concept to deployment. Companies with established relationships with government agencies or deep pockets, such as Terrestrial Energy and Westinghouse, have an edge in attracting the necessary investments to move their projects forward.

Segment Overview

Based on coolant, the market is segregated as heavy liquid metal, gases, molten salt, and water. The water segment will account maximum share for the small modular reactors market during the forecast period SMR's water usage is a critical factor particularly in regions facing water scarcity and the effects of climate change. Additionally, the water consumption of SMRs vary depending on the reactor design, cooling technology, and local environmental conditions. When evaluating the water consumption implications of SMRs, it’s helpful to compare them to other energy sources, such as fossil fuels, renewables, and traditional nuclear power plants.

Further, based on location, the marine segment will account fastest growing CAGR for the forecast period Marine-based SMRs play a vital role in decarbonising industries across marine environments and niche markets. Also, desalination requires a significant amount of energy to convert seawater into fresh water. Therefore, marine-based SMRs can provide a stable and continuous power source for desalination, particularly in coastal areas with fresh water scarcity.

Geographical Overview

North America dominated the small modular reactor market accounting highest market share and is expected to sustain its dominance during the forecast period The region’s focus towards eliminating greenhouse gas emissions and transition to a carbon-free economy is one of the primary drivers of the small modular reactor market.

Europe is emerging as the second-largest market for small modular reactors (SMRs), supported by initiatives like the European Industrial Alliance on SMRs launched in 2024 to accelerate deployment. Asia Pacific will witness the fastest growth as countries such as China, India, and Southeast Asian nations adopt SMRs to meet rising energy demand and emission goals. Latin America is turning to SMRs to modernize energy infrastructure, reduce carbon footprints, and supply power to remote regions. Meanwhile, the Middle East and Africa are investing in advanced SMR technologies to enhance clean energy capacity, strengthen energy security, and support long-term decarbonization.

Key Trends and Drivers

Growth and Innovation in the Small Modular Reactor Market -

The small modular reactor (SMR) market is experiencing transformative growth driven by the rising demand for flexible and cost-effective power generation solutions. As countries increasingly seek adaptable energy technologies, SMRs offer a compact alternative to traditional large-scale reactors, producing up to 300 MW of electricity per module. This makes them particularly attractive for replacing aging fossil fuel plants, given their lower upfront costs and versatility in integration within diverse energy systems. Notably, their design includes inherent and passive safety features, significantly enhancing overall safety and reliability compared to conventional reactors.

Technological Advancements -

Advanced Small Modular Reactors (SMRs) are a key part of the Department’s goal to develop safe, clean, and affordable nuclear power options. The advanced SMRs currently under development in the United States represent a variety of sizes, technology options, capabilities, and deployment scenarios. These advanced reactors, envisioned to vary in size from tens of megawatts up to hundreds of megawatts, can be used for power generation, process heat, desalination, or other industrial uses. SMR designs may employ light water as a coolant or other non-light water coolants such as a gas, liquid metal, or molten salt. As part of the VOYGR project, NuScale partnered with ATS to develop a first of a kind technology called MAEB or Modular Assembly Bolting Equipment. MAEB is a key piece of equipment used in the process to disassemble and reassemble the Power Modules for routine maintenance, inspection, and refueling.
