Labour bets on atomic power and American capital to turn diplomacy into jobs, investment and energy security

Prime Minister Keir Starmer will today unveil a UK–US civil nuclear energy agreement designed to accelerate the roll‑out of advanced reactors in Britain, part of a flurry of pledges timed to precede this week’s state visit by U.S. President Donald Trump. The initiative is intended to lock in new investment, sharpen the UK’s energy security and demonstrate that the Labour government’s overtures to Washington can translate into tangible economic gains.

The package, trailed by officials in London and Washington, is expected to fast‑track key aspects of safety assessments for next‑generation designs, open new channels for nuclear fuel supply and underwriting, and pave the way for a set of commercial tie‑ups to be showcased during the visit. U.S. briefings point to more than $10 billion in deals across technology and energy to be announced over the week, with civil nuclear at the centre.

Central to the plan is a commitment by British and U.S. regulators to recognise one another’s work wherever possible—allowing evidence gathered for one authority to be used by the other and, for certain advanced designs, cutting the effective time to regulatory clearance to around two years. Officials stress that neither side is compromising on safety; the aim is to remove duplication and sequence steps more efficiently.

Several commercial partnerships are expected to be folded under the umbrella of the agreement. UK energy supplier Centrica and U.S. reactor developer X‑energy are preparing plans for as many as a dozen advanced modular reactors at and around Hartlepool in northeast England. Backers say the programme could eventually power roughly 1.5 million homes and support about 2,500 skilled jobs in the region, alongside a UK‑wide fleet.

Fuel supply and industrial capacity are also in focus. London and Washington are moving to expand Western production of advanced nuclear fuels and to eliminate Russian material from their civil supply chains by the end of the decade. In Cheshire, enrichment company Urenco is building an Advanced Fuels Facility that the government says will support around 400 highly skilled jobs and help anchor next‑generation reactor projects.

Beyond electricity, ministers are keen to showcase nuclear’s role in the broader economy. Pilot projects under discussion include powering new AI‑heavy data centres with dedicated reactors in Nottinghamshire and the potential siting of a micro‑modular unit at London’s Gateway Port to support logistics operations—examples of how steady, low‑carbon baseload could be plugged directly into strategic infrastructure.

For Starmer, the timing is deliberate. President Trump arrives for a three‑day state visit that will blend royal ceremony with a business push: a state banquet at Windsor Castle on Wednesday and a working session with the prime minister at Chequers on Thursday, book‑ended by meetings with King Charles and Queen Camilla. The civil nuclear package is designed to give the week a signature economic deliverable, as both sides court investors.

“This landmark UK‑US nuclear partnership is not just about powering our homes, it’s about powering our economy,” Starmer said in prepared remarks ahead of the visit. Supporters argue the strategy could push down household bills over time by reducing exposure to volatile gas prices while delivering thousands of jobs during construction and decades of highly paid work in operations and maintenance.

Industry players have welcomed the direction. Rolls‑Royce, whose small modular reactor design is working through approvals, said closer UK‑US co‑operation and clearer timetables would make it easier for companies to raise capital and scale domestic supply chains. U.S. developers likewise see a path to deploy in Britain and export back into North America once designs have cleared regulatory hurdles on both sides.

Yet turning ambition into kilowatt‑hours will test the system. Britain is rebuilding its nuclear workforce after decades of stop‑start policy and has ageing stations due to retire. Colleges and employers are scrambling to train welders, electricians and nuclear‑grade engineers; that skills pipeline will need sustained funding. Planning and local consent remain sensitive, especially for on‑site fuel facilities and new grid infrastructure.Financing is another hinge. Large reactors like Sizewell C are being developed with a regulated asset base model that puts some construction risk on bills in exchange for a lower cost of capital. Smaller reactors will likely rely on a mix that includes contracts for difference, government support for first‑of‑a‑kind units and private balance sheets. Investors will look for clarity on revenue guarantees, waste liabilities and long‑term fuel supply.

Environmental groups urge ministers to prioritise energy efficiency and renewables, warning that nuclear projects often arrive late and over budget. The government replies that Britain needs reliable, low‑carbon baseload to complement wind and solar and to meet electrification goals in transport, industry and heating. Analysts say a diversified mix lowers overall system costs and reduces the need for fossil back‑up and imported gas.

The promise of faster approvals will be watched closely by regulators and communities. ‘Mutual recognition’ in practice can mean different things: from accepting data packages and test results produced for another authority, to running parallel rather than sequential reviews. Officials insist that any acceleration will be bounded by full legal processes, including public consultations and site‑specific permits.

Local leaders in the Tees Valley and in Nottinghamshire are already positioning for investment, citing shovel‑ready industrial land near grid nodes and ports. Supply‑chain firms—from heavy forgings and valves to digital controls and fuel‑cycle services—see multi‑year order books if Britain commits to a fleet approach rather than a handful of one‑off projects. The risk, as previous decades show, is that momentum ebbs after the headlines.

Across the Atlantic, the Biden‑era Inflation Reduction Act’s production tax credits for nuclear remain in place, and Washington has earmarked funds to restart domestic fuel production for advanced reactors. U.S. officials say deeper UK‑US alignment on standards and fuel will make it easier to finance projects in both countries and to offer an allied alternative to Russian and Chinese suppliers.

What happens next is partly choreography. The U.S. delegation, including senior officials and business leaders, will attend the state banquet on Wednesday before heading to Chequers for a working lunch and joint press conference on Thursday. Additional details of the civil nuclear framework and a wider science‑and‑technology partnership are expected to be unveiled alongside sector‑specific investment announcements.

For Labour, the calculus is political as well as economic. A visible, jobs‑first nuclear push dovetails with pledges to restore industrial capacity and deliver ‘securonomics’—using government to crowd in private capital for strategic infrastructure. For Trump, the visit offers a stage to underline U.S. leadership in energy and defence technology while showcasing American firms at the heart of Britain’s next wave of growth.

Even if the headlines this week are large, the milestones that matter are prosaic: contracts reaching financial close, skills academies turning out qualified workers, regulators publishing clear timetables, and shovels in the ground at priority sites. If those pieces click, advanced nuclear could shift from promise to production over the next few years—powering data centres and homes alike, and giving both governments a claim to durable progress.
