The last of the Magnox-type reactors to be implemented in the UK, Wylfa has been producing electricity day in, day out since its opening in 1971. On a typical day it supplies 23 million kWh of electricity - enough to meet the needs of two cities the size of Liverpool and Manchester put together. Its 50 hectare site is located on the north coast of Anglesey, giving access to all the cooling water the plant needs directly from the sea.
