The Donald Trump administration on Tuesday, 23 June unveiled a USD 17.5 billion financing programme to rebuild the US nuclear supply chain and accelerate construction of 10 new large-scale nuclear reactors, marking one of the most ambitious commercial nuclear revivals in decades. The initiative, announced by the US Department of Energy (DOE), centres on conditional loan commitments for long-lead components based on Westinghouse's AP1000 reactor design.

What the Programme Covers

The DOE's financing will support up to five projects, each involving two reactors, for a combined capacity of more than 11 gigawatts of electricity — enough, officials said, to power nearly 10 million American homes. The loans are not intended to fund reactor construction directly. Instead, they will finance the procurement of critical long-lead items — including reactor pressure vessels, steam generators, and structural modules — components that can take years to manufacture and have historically bottlenecked new builds.

What the Government Said

US Energy Secretary Chris Wright framed the announcement as the centrepiece of a broader nuclear renaissance strategy. 'Just over one year ago, President Trump directed the Energy Department and its agency partners to unleash the next American nuclear renaissance,' Wright said. He added that the conditional loans would 'play an important role in reviving the supply chain needed for America to once again build large-scale commercial reactors' and could accelerate construction timelines by up to three years, lowering costs in the process.

Greg Beard, who heads the Energy Dominance Financing office, explained the rationale for the scale: 'The way to drive down cost in nuclear is to standardise and repeat build the same design.' He said the programme was obligating USD 17.5 billion in supply-chain financing with a target of having 10 large reactors under construction by 2030.

Private Sector Participation Required

The programme demands significant private co-investment. Westinghouse and each utility or energy-company partner must each commit approximately USD 500 million in equity before DOE financing is released — creating roughly USD 1 billion in private investment per project. Officials confirmed that seven utilities and energy companies have already signed letters of intent, though only five projects will be selected in the initial round. More than 100 companies across more than 40 US states are expected to benefit from the supply-chain build-out, according to Beard.

AI Demand and Energy Economics

Administration officials pointed to surging electricity demand from hyperscale data centres and artificial intelligence infrastructure as a key demand driver. 'The world-changing growth of AI is driving enormous demand for electricity by companies who are willing to pay more for that power,' Beard said. Wright indicated that long-term power purchase agreements from technology companies could underpin project economics without raising consumer electricity rates. 'We think this will be the start,' Wright said, adding he would 'be very surprised' if dozens more reactors were not built in the coming years.

Background and Lessons from Vogtle

Westinghouse's AP1000 design is already operational at the Vogtle nuclear plant in Georgia, where Units 3 and 4 entered service after significant delays and cost overruns. Officials said lessons drawn from those projects, combined with a standardised design and a rebuilt domestic supply chain, should improve timelines and reduce costs for future builds. Nuclear energy currently supplies approximately one-fifth of US electricity and remains the country's largest source of carbon-free power. The announcement is part of a wider Trump administration push to expand domestic energy production and strengthen US manufacturing.
