UK and US to Sign Landmark Nuclear Power Partnership During Trump Visit

Britain and the United States are set to sign a landmark nuclear power deal during U.S. President Donald Trump’s state visit this week, the UK government announced. The partnership is designed to accelerate investment in new nuclear plants, improve energy security, and cut project approval timelines.

The UK has launched a major nuclear expansion push, pledging £14 billion ($19 billion) to build Sizewell C and supporting Rolls-Royce in developing the nation’s first small modular reactors (SMRs). The new U.S.-UK tie-up will enhance collaboration on regulation, allowing both nations to share safety approvals and cut licensing times from up to four years to just two.

Key investments are expected to be unveiled, including a deal between U.S.-based X-Energy and Britain’s Centrica to build as many as 12 advanced modular reactors in northeast England. Another project worth £11 billion ($15 billion), led by Holtec International, EDF, and Tritax, will create advanced data centres powered by SMRs at the former Cottam coal station in central England.

UK Prime Minister Keir Starmer called the commitments a step toward a “golden age of nuclear,” promising lower household bills and stronger energy resilience. U.S. Energy Secretary Chris Wright added that the deal will unlock greater commercial access across both nations.

Industry leaders welcomed the plans. Centrica CEO Chris O’Shea highlighted the move as vital for building a low-carbon energy future, while X-Energy’s J. Clay Sell pointed to Hartlepool as a key hub. Holtec’s Kris Singh emphasized job creation, and EDF UK chief Simone Rossi underlined benefits for energy security.

Rolls-Royce also announced it has entered the U.S. regulatory process for its SMR, opening the door to further investment and jobs. Meanwhile, UK-based Urenco will supply advanced low-enriched uranium to the U.S. market.
