The last working Magnox nuclear reactor in the world will continue running until December 2015.

Yesterday regulators gave Magnox thumbs up to prolong the Wylfa power plant’s life.

It was originally scheduled to stop generating power in 2010.

To keep Wylfa running, partially used fuel must be transferred from Reactor 2 to Reactor 1.

Stuart Law, Wylfa Site Director said: “This will be Wylfa’s final period of generation. After December 2015, we will follow in the footsteps of other Magnox sites and begin to defuel the reactor which will take up to three years.”

The company estimates the extra electricity generation could mean an extra £785 million to the UK taxpayer.
