46 years on, Hinkley Point B changes hands. The job now is taking it apart

What happened

On 1 October 2026, Hinkley Point B nuclear power station in Somerset transferred from EDF to the Nuclear Decommissioning Authority. The NDA is the public body responsible for cleaning up Britain's old nuclear sites. Day-to-day work will be done by its subsidiary, Nuclear Restoration Services. Hinkley Point B generated electricity for 46 years. It started up in 1976 and stopped generating in 2022. Over that time, the NDA says the station created more than £15 billion in economic value. Around 250 EDF staff moved across to Nuclear Restoration Services as part of the handover. The site now sits alongside two neighbours. Hinkley Point A, an older station, is already managed by Nuclear Restoration Services. Hinkley Point C is being built on adjacent land. Hinkley Point B is not the only station making this journey. It is part of the UK's fleet of advanced gas-cooled reactors, known as AGRs, and all of them are due to transfer in turn. Hunterston B transferred in April 2026. Dungeness B is expected before the end of the decade. Hartlepool, Heysham 1, Heysham 2 and Torness will follow. The money for this does not come out of the general NDA budget. Decommissioning of the AGR fleet is paid for from the Nuclear Liabilities Fund, which is ring-fenced for the purpose. NDA Group chief executive David Peattie said: 'We're proud to draw on decades of expertise, applying proven skills to safely decommission the AGR fleet.' For some sense of local scale, the NDA's 2024/25 estimates put Hinkley Point A's contribution at £31 million locally and £61 million across the UK.

Why this matters

Most energy news is about building things. This is about the opposite, and it is a far bigger job than most people realise. Taking a nuclear power station apart is not demolition. It is a decades-long engineering programme. Fuel has to be removed and sent away. Radioactive parts have to be allowed to cool, sometimes for many years. Buildings come down in a planned order. Waste has to be sorted, packaged and stored in forms that will stay safe for a very long time. The NDA describes it as a complex, long-term undertaking. That is not corporate caution. Some stages of this work will be finished by engineers who have not been born yet. There is a jobs story here too, and it is a more cheerful one than it sounds. When a power station stops generating, the obvious fear in the local area is that the work goes with it. In this case, 250 people moved from one employer to another and stayed on site. Decommissioning keeps skilled engineering and project work in coastal communities for decades after the last unit of electricity is sold. The third reason it matters is that it is already paid for. The Nuclear Liabilities Fund was set up so that the cost of cleaning up these stations was put aside while they were still earning. Whether it is enough is a question the National Audit Office and others keep asking. But the principle, money set aside in advance for a bill that arrives later, is a sound one.

What the evidence actually says

A few of the figures in this announcement deserve a closer look. **The £15 billion.** This is described as economic value created by Hinkley Point B between 1976 and 2024. Figures like this come from economic modelling. They usually include wages, supplier spending and the knock-on effects of both. They are useful for showing scale, but they are estimates, and different methods produce different totals. Treat it as 'very large' rather than as a precise accounting figure. **The 46 years.** This is solid. Generation ran from 1976 to 2022. Hinkley Point B was originally expected to run for far less than that; its life was extended more than once after inspections of the graphite cores. **The timescales.** The NDA has published strategies for AGR decommissioning, and they are measured in decades. There is no date in this announcement for when Hinkley Point B will be fully cleared, and that is normal rather than evasive. Programmes of this length do not have reliable end dates at the start. **The transfer itself.** This is a change of ownership and responsibility, not a change in the physical state of the site. The reactors have already stopped. Defuelling work has been under way. The announcement marks the point at which the NDA takes charge, not the point at which something new begins happening on the ground. One thing worth saying clearly, because it is the question most people actually have: a station transferring to the NDA is not a sign of a safety problem. Every AGR in Britain is scheduled to make this transition at the end of its generating life. This is the system working as designed.

Practical advice

There is nothing here that requires a household to do anything. But if you live near a nuclear site, or you are interested in the work, a few things are genuinely useful to know. **Nuclear sites publish their own local information.** Nuclear Restoration Services runs site stakeholder groups, which are public meetings where residents can ask questions about work on site. Details are on the NDA and NRS pages on gov.uk. **Environmental monitoring around nuclear sites is public.** The Environment Agency and the Food Standards Agency jointly publish an annual report called Radioactivity in Food and the Environment, covering samples taken around UK nuclear sites. Anyone can read it. **If you want this kind of work as a career, decommissioning is hiring for a long time.** The AGR programme will run for decades and needs engineers, project managers, health physicists, welders and electricians. Nuclear Restoration Services and the NDA advertise through gov.uk and their own recruitment pages. **Be wary of alarming claims online.** Nuclear sites attract a lot of confident misinformation in both directions. The regulators here are the Office for Nuclear Regulation and the Environment Agency, and both publish their findings. Go to them rather than to a social media thread. **If you are a supplier, the supply chain opportunities are published.** The NDA group publishes contract opportunities, and the AGR transfers bring a long pipeline of work with them.

What to know

Hinkley Point B in Somerset transferred from EDF to the Nuclear Decommissioning Authority on 1 October 2026, to be managed by Nuclear Restoration Services. Around 250 EDF staff moved with it. The station generated from 1976 to 2022, a 46-year run, and the NDA estimates it created more than £15 billion in economic value. It joins Hinkley Point A, already in NRS hands, next door to Hinkley Point C under construction. Hunterston B transferred in April 2026. Dungeness B, Hartlepool, Heysham 1, Heysham 2 and Torness are still to come. The work is funded from the ring-fenced Nuclear Liabilities Fund, and it will take decades. The short version: this is the planned end of a power station's life, not a problem. It keeps skilled work in a coastal community long after the electricity stopped, and the bill was set aside in advance.
