Oldbury nuclear power station is a nuclear power station located on the south bank of the River Severn close to the village of Oldbury-on-Severn in South Gloucestershire, England. It is operated by Magnox North Limited, on behalf of the Nuclear Decommissioning Authority (NDA).
Opened in 1967, it had two Magnox reactors producing 424 megawatts (MWe) in total.
The design net power output of the station was 600 MWe, but due to steel corrosion problems from the hot carbon dioxide coolant within the reactor, operating temperature had to be reduced soon after operation started causing a large drop in power output.
The power station was due to cease operation in 2008, with decommissioning due to begin in 2009. An announcement on 18 December 2008 by the UK Nuclear Decommissioning Authority stated that the station will continue to operate for another two years.
The Nuclear Directorate has allowed one reactor at the station to operate until June 2011. The operators applyied for the same extension for the other reactor. On 29 February 2012, the last of the Oldbury Magnox reactors was finally shut down.
On 9 February 2011 the Nuclear directorate allowed Rector 2 to continue operating until 30 June 2011.
