Wylfa
Wylfa Site is located on a 20 hectare site on the north coast of Anglesey. It was the last and biggest of the Magnox stations to be built and shut down in 2015 having completed almost 45 years of operation, generating a total of 232 terawatt hours of electricity.
The site is now in its defuelling phase to remove spent fuel elements from the twin reactors. A remediation project is underway to remove and clean asbestos from areas within the reactor buildings and turbine hall.
Wylfa is also responsible for the Maentwrog hydroelectric station near Blaenau Ffestiniog, Gwynedd.
