The government has announced plans to make it easier to build mini nuclear power stations in England and Wales, as part of its efforts to boost UK economic growth.
It said it will reform the “archaic” planning rules which ministers believe have held Britain back in the global race for clean, secure and affordable energy.
Prime Minister Sir Keir Starmer said the country had been “let down and left behind” because it had not built a nuclear power station in “decades” – and the plans will create thousands of highly skilled jobs.
Unions and business groups welcomed the move, but environmentalists criticised the government, saying it had “swallowed nuclear industry spin whole”.
Nuclear power provides around 15% of the UK’s electricity but many of the country’s ageing reactors are due to be decommissioned over the next decade.
Mini nuclear power stations – or small modular reactors (SMRs) – are smaller and cheaper than traditional nuclear power plants, and produce much less power.
The plans announced on Thursday will mark the first time SMRs will be included in planning rules. A list of the only places a nuclear reactor could be built will also be scrapped. The list was made up of just eight sites.
Sir Keir said Britain’s energy security had been “held hostage” by Russian President Vladimir Putin for “too long”, which has resulted in prices “skyrocketing at his whims”.
“I’m putting an end to it – changing the rules to back the builders of this nation, and saying no to the blockers who have strangled our chances of cheaper energy, growth and jobs for far too long,” he explained.
The process of choosing to loosen rules on where nuclear reactors could be built began under Rishi Sunak’s Conservative government with a consultation in January 2024.
Ministers said Britain is considered one of the world’s most expensive countries in which to build nuclear power, and a new Nuclear Regulatory Taskforce will be established to speed up the approval of new reactor designs and stream line how developers engage with regulators.
Conservative shadow energy secretary Andrew Bowie said it was “about time” Labour followed his party’s lead in recognising the benefits “of stable, reliable, baseload nuclear power”.
But Doug Parr, policy director of Greenpeace UK, claimed the government had not applied “so much as a pinch of critical scrutiny or asking for a sprinkling of evidence”.
“The Labour government has swallowed [the] nuclear industry spin whole,” he said, adding: “They present as fact things which are merely optimistic conjecture on small nuclear reactor cost, speed of delivery and safety.”
The head of the Nuclear Industry Association, Tom Greatrex, called the reforms the “strongest signal yet” towards growth and clean power.
Gary Smith, GMB’s general secretary, said the union has repeatedly said “there can be no net zero without new nuclear”.
Referring to Sizewell C, the site on the Suffolk coast on which then prime minister Boris Johnson pledged a new nuclear reactor on in 2022, he added: “[It] stands ready and waiting for the green light to power up our country’s future.”
The government has not yet made a final decision on Sizewell C, which is not due to come until the spending review later this year. The final choice on the design of the SMRs will also come at the same time.
Currently, progress building nuclear power stations in the UK can be slow – to get from planning to “power on” can take nearly 20 years. Consultations for Sizewell took 10 years alone.
On Wednesday, joint managing director of Sizewell C, Julia Pyke, called the project “the next step” in the journey towards growth and energy security.
