UK Government Takes Control of Hunterston B as Landmark Nuclear Decommissioning Begins
Transfer to public ownership marks first step in dismantling ageing reactor fleet, with Hunterston B leading a decade-long transition
The United Kingdom government is preparing to take control of the Hunterston B nuclear power station in Scotland, marking a significant milestone in the country’s long-term strategy to dismantle its ageing reactor fleet.
The North Ayrshire site, which ceased generating electricity in 2022, is set to transfer from EDF to the Nuclear Decommissioning Authority on 1 April 2026. The move will formally place the facility under public ownership, enabling full-scale decommissioning to begin.
Regulatory approval has already been secured, with the Office for Nuclear Regulation granting a new site licence to Nuclear Restoration Services, a subsidiary of the authority.
This licence will take effect at the point of transfer, shifting legal responsibility for the site and its operations away from EDF and into the hands of the government’s decommissioning body.
Hunterston B will become the first of the UK’s advanced gas-cooled reactor stations to undergo this transition.
Officials have indicated that six additional sites will follow in a phased programme over the coming decade, as the country completes the retirement of its second-generation nuclear infrastructure.
More than two hundred and forty skilled workers are expected to transfer with the site, ensuring continuity of expertise as the focus shifts from electricity generation to dismantling and environmental remediation.
The process will involve the removal of remaining structures, treatment and storage of radioactive materials, and eventual preparation of the site for long-term monitoring.
Fuel has already been removed from the reactors, a crucial step that allows the next phase of decommissioning to proceed safely.
The site is now entering a complex and multi-decade programme that will include initial dismantling followed by a prolonged period of care and maintenance.
The transition reflects broader changes in the UK’s energy landscape, as older nuclear stations reach the end of their operational life while new projects and alternative energy sources are developed.
Hunterston B, which operated for more than four decades and supplied electricity to millions of homes, now stands at the forefront of a nationwide effort to manage the legacy of nuclear power responsibly.
Government officials have described the transfer as a critical step in ensuring that decommissioning is carried out safely, efficiently, and with sustained oversight, as the UK enters a new phase in its nuclear lifecycle.
