Britain’s nuclear power capacity was boosted by 1,500 MW yesterday when three nuclear power plants were restarted.

EDF restarted Sizewell B2 and Dungerness B21 yesterday after a seven week refuelling outage while Magnox fired up its 310 MW unit at Wyfla which had been shutdown for just over a week because of an unplanned outage.

On Friday Magnox confirmed that its two reactors at Oldbury will close next year after 44 years of operation. The whole site was originally due to shut in 2008 but it was decided to extend its life after talks with the Nuclear Decommissioning Authority and the Office for Nuclear Regulation.

Phil Sprague, Oldbury site director, said: “Oldbury has provided the UK with a vital source of power for over four decades, something that everyone who has worked at the site, past and present, should be very proud of.”
