Hinkley Point B is a nuclear power station near Bridgwater in Somerset. The station was the first Advanced Gas-cooled Reactor to generate electricity to the grid in the UK. When it finished generating in August 2022 it was the most productive nuclear power station the UK has ever had.
Hinkley Point B decommissioning
Hinkley Point B stopped generating electricity in August 2022 after 46 years of service. Over the next few years EDF will remove the used fuel from the reactors and prepare for the decommissioning of the nuclear power station.
Decommissioning will involve dismantling and demolition of plant and buildings on the Hinkley Point B site and will be carried out by Magnox, which is part of the Nuclear Decommissioning Authority.

Hinkley Point B generated 311TWh, enough to power every home in the South West for 33 years

Marking the end of 46 amazing years of generation at Hinkley Point B nuclear power station
As we mark the end of 46 amazing years of generation at Hinkley Point B, our employees have been talking about what has made the nuclear power station so special.
From the community spirit of those who work there to the amount of energy supplied to the UK, there is so much to celebrate and be proud of.

How do you decommission a nuclear power station?
By 2030 all seven of EDF’s AGR nuclear power stations are expected to have ended power generation and be at various stages of decommissioning.
How we generate our power
As Britain's biggest generator of zero carbon electricity(1) we generate power from wind + nuclear + solar.
Hinkley Point C
Hinkley Point C nuclear power station is currently under construction and is the first nuclear power station to be built in the UK in a generation. The twin unit UK EPR reactors will be capable of generating 3,260MW of secure, low-carbon electricity for 60 years.
