Hunterston A nuclear power station was a Magnox power station located at Hunterston in Ayrshire, Scotland, adjacent to Hunterston B and is currently being decommissioned. ==History== Construction of the power station, which was undertaken by a consortium of GEC and Simon Carves,〔(UK Consortia ) NEI Magazine, August 2009〕 began in 1957 and the facility was opened by Her Majesty Queen Elizabeth, the Queen Mother on 22 September 1964. Hunterston A had two Magnox reactors capable of generating 180 MWe each.〔(Nuclear Power Plants in the UK - Scotland and Wales )〕 The reactors were supplied by GEC and the turbines by C.A. Parsons & Company.〔 The main civil engineering contractor was Mowlem.〔 The Magnox reactors used natural uranium fuel (in magnox alloy 'cans') within a graphite core, and were cooled by carbon dioxide gas. Each reactor, which consisted of more than 3000 fuel channels, was enclosed in a steel pressure vessel. Eight boilers, known as Steam Raising Units, were located around each reactor. An outer building, mainly of glass, provided weather protection. The six 60 MW generators were located in an adjoining turbine hall. The Hunterston A reactor design was unique in that each was raised up to a height of over 10 metres to enable refuelling to take place from underneath. This meant that gravity assisted the process of used fuel removal, and avoided the need for lifting machinery to be inserted into the active core for on-load refuelling.〔(Magnox North: site history )〕 In later years of operation the reactors were derated to 150 MWe each. This was to slow the corrosion of steel components which, at the original higher temperatures, could have compromised reactor life. The construction of Cruachan Power Station, a pumped-storage hydroelectric dam and power station, was linked to that of Hunterston A, to store its surplus night-time generated electricity. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hunterston A nuclear power station」の詳細全文を読む スポンサード リンク
