The government has released an Advanced Nuclear Framework on Wednesday 4 February 2026, pitched as the move from pilot ideas to bankable projects. The priority is straightforward: bring private capital into advanced and small modular reactors that can power factories and AI data centres while protecting billpayers with clean, homegrown energy.

From March 2026 developers can apply to join a new pipeline if they meet readiness tests on technology status, developer capability and financing plans. Successful applicants gain an in‑principle government endorsement and a concierge‑style service to navigate planning, regulation and fuel questions, with the aim of crowding in private investment rather than leaning on the state balance sheet.

Support is designed to improve bankability, not write blank cheques. The framework signals revenue support once plants are operational and narrowly defined risk protections for extremely rare events. Projects are expected to be privately financed, but with targeted tools that reduce tail risks and lower the cost of capital for credible schemes.

Named corporate plans give the policy immediate shape. X-energy and Centrica are preparing up to 12 advanced modular reactors at Hartlepool, which Centrica says could support around 2,500 jobs. Holtec, EDF and Tritax intend to deploy Holtec’s SMR-300 at the former Cottam coal site in Nottinghamshire, directly supplying clean, secure power to data centres on the site. TerraPower is working with KBR to explore the UK deployment potential of its Natrium technology.

For energy‑intensive compute, the attraction is firm, low‑carbon power with scope for direct supply. Advanced reactors operate at higher temperatures, creating options for both electricity and usable heat for industrial processes or data centre cooling. Co‑location can reduce grid connection delays, making long‑dated private power purchase agreements more viable than in previous nuclear cycles.

The technology set spans advanced, small and micro modular reactors manufactured in factories. Standardised modules should shorten build schedules, spread skilled work across multiple regions and bring more predictable costs than one‑off gigawatt‑scale plants. Government officials frame this as a route to deliver capacity at pace without compromising safety.

Capital formation sits at the centre of the plan. The National Wealth Fund can step in as a catalytic investor where projects meet its criteria, helping to de‑risk early equity and anchor follow‑on finance. Great British Energy‑Nuclear will run a disciplined process that, in the words of its CFO Neil Cooper, is evidence‑led rather than optimism‑led, giving developers and lenders a single point of contact.

Fuel and sites are being addressed in parallel. A new Statement on Civil Nuclear Fuel Use sets expectations for uranium‑based fuels to align with energy security, environmental protection and long‑term waste management. The Nuclear Decommissioning Authority is releasing surplus land for clean energy projects at Chapelcross in Scotland, Pioneer Park in Cumbria and Trawsfynydd in Wales.

The framework builds on recent decisions, including the go‑ahead for Sizewell C in Suffolk and the selection of Wylfa in North Wales for the UK’s first small modular reactors. Industry figures, including EDF and the Nuclear Industry Association, argue that clear project recognition, UK‑US corporate partnerships and proposed regulatory reforms from the recent Fingleton review should improve financeability.

Timelines remain ambitious. Developers are targeting the mid‑2030s for the first advanced modular reactors to enter service in Britain, subject to licensing, siting and financing milestones. Near term, the marker to watch is March 2026, when pipeline submissions open and the first endorsements can start shaping order books and supply‑chain commitments.

For investors, the key questions are practical. How firm will revenue support be, and will it reward availability and output without shifting undue risk onto billpayers? What precisely counts as a “rare event” for risk cover, and who provides it? How will fuel supply and spent‑fuel obligations be priced? These design choices will set the cost of capital more than any headline announcement.

For operators planning AI data centres or high‑heat industrial processes, this is a planning window rather than a finished deal. Co‑location at sites such as Cottam or Hartlepool could lock in predictable, inflation‑linked energy if projects progress. Equally, delays in consenting or fuel rules would push delivery to the right. We’ll be tracking which consortia convert today’s intent into shovel‑ready projects and how quickly offtake agreements materialise.
