Here’s the latest I can confirm from public updates up to April 2026.
- Rolls-Royce SMR Ltd has been advancing the UK’s generic design assessment (GDA) for its 470 MWe small modular reactor design, with Step 2 already completed and Step 3 underway as of mid-2024. The process is expected to conclude by the end of 2026, after which site-specific approvals would follow. This information comes from UK nuclear regulatory and industry updates on the GDA timeline and status [No2NuclearPower article, 2024; ElectricityInfo article, 2024].[1][2]
- In 2025, the UK government publicly selected Rolls-Royce SMR as the preferred bidder to develop the country’s first SMRs as part of a broader strategy to secure low-carbon energy, under a partnership framework with Great British Energy - Nuclear. The announcement highlighted the competitive, two-year procurement process and potential strategic tech development partnerships, reinforcing the UK’s position in the global SMR race [UK government press release, 2025].[4]
- There have been ongoing industry updates indicating momentum behind Rolls-Royce SMR’s deployment plans, including contract activity and regulatory progress. A 2026 Markets Screener item notes Rolls-Royce SMR securing a contract related to the UK’s SMR program with Great British Energy - Nuclear, dated April 12, 2026, signaling continued activity in the project’s development phase [Marketscreener summary, 2026].[3]
- Rolls-Royce SMR maintains a dedicated information hub and press releases detailing progress, milestones, and regulatory interactions. The company’s own press room and official SMR pages emphasize the aim of delivering a factory-built, affordable nuclear power plant and ongoing engagement with regulators and stakeholders [Rolls-Royce SMR press, 2026; Rolls-Royce SMR official site, 2023–2026].[7][9]
Illustrative note
- If you’re looking for a snapshot of the regulatory milestone: Step 2 GDA statements were granted, and Step 3 began, with the overall GDA program projected to wrap up in 2026, enabling site-specific approvals thereafter. This is the clearest, most consistent thread across multiple sources.[2][1]
Would you like a concise timeline (milestones by year) or a quick comparison of GDA status vs. government procurement events? I can also pull the exact statements from the cited sources if you want precise quotes.
