Scottish Nuclear owns and operates four advanced gas cooled reactors, two at Hunterston and two at Torness, having a design output capacity of 2640 MW(e), and generates around half of Scotland's electricity. II was formed in 1990 following the split-up of the South of Scotland Electricity Board (SSEB) prior to privatization. It has a staff of around 1700, with approximately 400 located at its East Kilbride design office.
