Hinkley Point B power station

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.

Since 1976 Hinkley Point B has generated 311 TWh of low carbon electricity

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.
