Fifteen years after the Sizewell C nuclear power station was proposed, the government will announce a £14.2bn commitment to the Suffolk site.
Chancellor Rachel Reeves is set to confirm the funding at the GMB union conference ahead of the spending review on Wednesday, which will set departmental budgets until 2029.
Energy Secretary Ed Miliband will call it a “golden age” of nuclear to boost the UK’s energy security.
The funding will go towards creating 10,000 jobs, the government will say, including 1,500 apprenticeships, and will support thousands more jobs across the UK.
On Monday, it was revealed Britain’s nuclear power sector grew by a quarter in 2024 to £20bn compared with three years ago, underpinned by a record workforce which has increased by a third, according to research by the Nuclear Power Association.
About 87,000 people now work in the industry, with the rise largely driven by new nuclear power projects at Sizewell C and Hinkley Point C in Somerset.
Sizewell C was initially proposed by French energy company EDF and China General Nuclear Power Group, but in 2022 the Conservative government bought the Chinese company out and the state now owns 83.5% of the project with EDF.

The green light for construction to begin was given in January 2024 under the Conservative government, and at last autumn’s budget, Ms Reeves announced a £2.7bn commitment to Sizewell C and said a final commitment would be announced in the 2025 spending review.
Construction is expected to take between nine and 12 years and when it is complete, it will provide around six million homes with nuclear energy.
A total of £330m of contracts have been signed with local companies, with 70% of all contracts expected to go to 3,500 British suppliers.
Ms Reeves said: “Today we are once again investing in Britain’s renewal, with the biggest nuclear building programme in a generation. This landmark decision is our Plan for Change in action.
“We are creating thousands of jobs, kickstarting economic growth and putting more money in people’s pockets.”
HS2 all over again?
Campaign group Stop Sizewell C called it “HS2 mark 2” after the high-speed train line that has faced high costs, delays and parts of it being axed.
They questioned how much money the government will ultimately invest in the nuclear power station as they said no information has been provided about the expected total costs.

Why did the PM visit a nuclear-armed submarine?
Alison Downes, from Stop Sizewell C, said: “Where is the benefit for voters in ploughing more money into Sizewell C that could be spent on other priorities, and when the project will add to consumer bills and is guaranteed to be late and overspent just like Hinkley C?
“Ministers have still not come clean about Sizewell C’s cost and, given negotiations with private investors are incomplete, they have signed away all leverage and will be forced to offer generous deals that undermine value for money. Starmer and Reeves have just signed up to HS2 mark 2.”
Or vital step towards domestic clean energy?
But the funding was called a “vital step toward delivering the secure, domestic clean energy” the UK needs by “pro-growth” campaign group Britain Remade.
Sam Richards, CEO of the Conservative thinktank, added: “The government must go much further.”
He called for less red tape to speed up the planning process and to show a “real commitment” to building nuclear power stations.
