Scope and Content Turbine hall from north-east, Hunterston 'A' Nuclear Power Station, North Ayrshire Hunterston 'A' nuclear power station, a magnox reactor, was commissioned in 1955, designed 1955-7 and built 1957-64. It closed in 1990, and is being decommissioned, a process which may take up to 135 years. The reactors are housed in two glass-fronted structures with curving sides, and are surrounded by lower buildings housing further machinery and supplies. This shows four of the six 60-megawatt GEC turbo-alternators. Each unit contains high- and low-pressure steam turbines and a generator running on the same axle. A condenser on the floor below cools the steam used to turn the turbines and returns it as water to the boiler. The floor above houses the switches which transform the power for use on the National Grid. Just one of these turbo-alternators could power one million 60w light bulbs, and during the station's working life over 54.9 terawatt hours (1 terawatt = 1 million megawatts) of power were produced (enough power to light 549 million 100w light bulbs for one hour). Hunterston 'A' power station has been selected as one of Scotland's key 20th-century Modern architectural monuments. Source: RCAHMS contribution to SCRAN.
