Sweden contract valued in the multibillion-pound range for three reactors. Czech Republic programme targets up to 3 GW.
2. Long-term service and after-sales support: Each SMR is designed for 60+ year operational life with >92% availability, generating recurring service revenue opportunities across the global fleet.
3. Government grant funding: £210 million grant funding from UK Research and Innovation (UKRI) for SMR design development and regulatory process, administered by SICE and overseen by the IPA, plus £2.6bn allocated in the 2025 UK Spending Review for the wider GBE-N programme.
4. Commercial loan financing: Up to £599 million commercial loan facility from the UK's National Wealth Fund to support finalisation of the generic design and progression of the SMR programme, repayable on deployment or refinancing.
5. Equity investment from strategic shareholders: Shareholders include Rolls-Royce plc, BNF Resources Ltd, Qatar Investment Authority (QIA) and ČEZ Group.

Core offering

Rolls-Royce SMR designs, engineers, manufactures and assembles factory-built 470 MWe Small Modular Reactor (SMR) nuclear power plants using a three-loop pressurised water reactor (PWR) design. Approximately 90% of each plant is factory fabricated, tested and delivered to site as modules under a single Engineering, Manufacture, Assembly (EMA) turnkey contract. The SMR delivers low-carbon baseload power (470 MWe / 1,358 MWth per unit) for at least 60 years, targeting state-owned utilities and government nuclear programmes in the UK, Czech Republic, Sweden and other markets.

Product overview

Rolls-Royce SMR's offering centres on a single core product — the Rolls-Royce SMR, a 470 MWe pressurised water Small Modular Reactor designed to be factory-built and shipped as modules to site. Supporting this core product is the Rolls-Royce SMR Explorer App, a digital companion providing interactive virtual tours of the reactor design. The two are complementary: the SMR is the physical power-plant product, while the Explorer App serves as a stakeholder engagement and visualisation tool for the same product.

Direct peers

• GE Hitachi Nuclear Energy: Joint venture between GE Vernova and Hitachi offering the BWRX-300, a 300 MWe boiling-water SMR. Directly competes head-to-head with Rolls-Royce SMR; the two were co-finalists in Vattenfall's Sweden technology selection process and BWRX-300 is the principal alternative in North American and European utility tenders.
• Holtec International: US-headquartered nuclear technology company developing the SMR-160, a 160 MWe PWR-based SMR. Targets similar state-owned utility and industrial off-taker customers and is pursuing UK GDA and European siting, making it a direct competitive alternative to Rolls-Royce SMR's 470 MWe product.
• NuScale Power: US SMR developer whose VOYGR plant is the only SMR design to have completed US NRC design certification. Competes for the same utility and government customers globally and is one of the leading western SMR vendors alongside Rolls-Royce SMR.
• Westinghouse Electric Company: Westinghouse is developing the AP300 SMR, a 300 MWe PWR leveraging its existing AP1000 large-reactor supply chain. It targets the same European utility customers and is a direct competitor in both new-build and SMR fleet programmes.
• X-energy: US developer of the Xe-100 high-temperature gas-cooled SMR and TRISO-X fuel. Targets industrial process heat, hydrogen and baseload power customers that overlap with Rolls-Royce SMR's emerging-use-case pipeline (SAF, hydrogen, data centres).

Emerging players

• TerraPower: Bill Gates-founded advanced nuclear developer building the Natrium sodium-cooled fast reactor and chloride molten salt testbed. Competes for the same government-backed advanced nuclear programmes and was a Dow/X-energy partner; an adjacent competitor to Rolls-Royce SMR in next-generation nuclear.

Broad incumbents

• EDF (Électricité de France): France's state-owned nuclear utility and one of the world's largest nuclear operators, currently building Hinkley Point C in the UK and developing its own Nuward SMR concept. Functions as both a potential Rolls-Royce SMR customer/partner in the UK and a competing SMR developer across Europe.

Others

• ČEZ Group: Czech state-owned utility and 20% equity shareholder in Rolls-Royce SMR as well as anchor customer for the Temelín 3 GW programme. Comparable as a European nuclear operator evaluating SMR fleet procurement, though not a competing vendor.
• Aker Solutions: Norwegian engineering and modularisation specialist and Rolls-Royce SMR's primary Module Partner. Comparable as a peer in industrial-scale modular construction and a key ecosystem enabler for factory-built SMR delivery, though not a competing reactor vendor.

Regional players

• Studsvik AB: Swedish nuclear services and fuel technology firm that has signed an MoU with Rolls-Royce SMR and acquired Karnfull Next, a Swedish SMR project developer that filed Sweden's first new nuclear site application in over 50 years. Operates in the same Nordic SMR ecosystem and overlaps in fuel qualification and plant life management.
