A nuclear reactor in Anglesey off the north west coast of Wales has been taken offline.
One of the reactors at the Wylfa nuclear power station, which powers two wind turbines, had refuelling problems on Sunday. Its operators Magnox are still investigating the cause of the failure.
Recently the plant was given permission to move fuel from one reactor to another to continue generating electricity. Reports claim it will be able to produce energy until the fuel runs out.
Wylfa is the only Magnox site still generating electricity and has two nuclear reactors and four turbine generators. The plant is claimed to generate more than 40% of Wales’ electricity needs.
