Trawsfynydd nuclear power station is a disused Magnox power station situated at Trawsfynydd in Gwynedd, Wales.

History

The power station was designed by Basil Spence. The construction, which was undertaken by a consortium involving Crompton Parkinson, International Combustion, Fairey Engineering and Richardsons Westgarth, and known as the Atomic Power Constructions (APC),^[1] began in July 1959, and both of the reactors were in operation by March 1965, with the station opening fully in October 1968, at a cost of £103 million.^[2] It had two Magnox reactors producing 470 megawatts (MW) in total.^[2] The reactors were supplied by APC and the turbines by Richardsons Westgarth.^[2] The civil engineering work was undertaken by Holland, Hannen & Cubitts^[3] and Trollope & Colls.^[4] The architectural consultant for the buildings was Sir Basil Spence and the landscape architect was Sylvia Crowe.^[5]

Both have been shut down since 1991; the site is in the process of being decommissioned by the Nuclear Decommissioning Authority.
