Small Modular Reactor (SMR) Market Competition Assessment Report 2026 - Market Share, Positioning, M&A and Company Profiles

Global Small Modular Reactor Market  Competitive Landscape

The global small modular reactor (SMR) market in 2026 comprises established nuclear technology companies, state-owned nuclear organisations, advanced reactor developers and specialised SMR technology providers. These players compete across light water, high-temperature gas-cooled, molten salt and sodium-cooled reactor technologies, strengthening their market positions through reactor capacity, technology maturity, plant footprint, refuelling cycles, project pipelines and international partnerships.

GE Vernova Hitachi Nuclear Energy (GVH), China National Nuclear Corporation (CNNC), Rolls-Royce SMR Limited, NuScale Power, TerraPower and X-energy hold competitive positions through differentiated reactor designs, technical capabilities, project development experience and global deployment strategies. Leading SMR developers are further distinguished by electrical and thermal capacity, outlet temperature, fuel characteristics, safety systems and commercialisation progress.

To accelerate SMR deployment across grid, industrial and other emerging applications, companies are increasingly prioritising technology advancement, supply chain development, regulatory progress, construction readiness, strategic offtake partnerships and international project pipelines.

Key Developments in the Small Modular Reactor Market

TerraPower Advances Natrium Reactor Development in the United States

In March 2026, TerraPower received approval to begin construction of its Natrium reactor project in Kemmerer, Wyoming, a major step towards the commercial deployment of its 345 MWe advanced reactor. The project pairs a sodium-cooled fast reactor with molten salt energy storage to enable flexible power generation, placing TerraPower among the leading developers moving advanced SMR technologies towards deployment.

Rolls-Royce SMR Strengthens Its Position in the Czech Republic

In July 2025, Rolls-Royce SMR increased its ownership position following the Czech Republic’s selection of its technology for potential deployment at the Temelín site. The development strengthens the company’s European project pipeline and moves its 470 MWe reactor design closer to commercial deployment.

Rosatom Advances RITM-200 SMR Deployment in Uzbekistan

In June 2025, Rosatom progressed manufacturing of the RITM-200 reactor for Uzbekistan’s first SMR power plant. The milestone advances the deployment of Rosatom’s land-based SMR technology and strengthens its international project pipeline across emerging nuclear energy markets.
