It consisted of the nuclear assets of the South of Scotland Electricity Board, which were later absorbed into the 1996 founded companies – Magnox Electric and British Energy.
On 1 April 1990, the nuclear generation assets (Hunterston A, Hunterston B and Torness Power Stations) of SSEB were vested with a new private company – Scottish Nuclear. The chairman of the company was Sir James Hann.
The remainder of the SSEB assets were privatised as ScottishPower in 1991.
In 1996, the older Magnox reactor – Hunterston A was transferred to Magnox Electric – established to own and operate a proportion of the old Magnox nuclear stations of Nuclear Electric.[2][3][4] The assets of Magnox Electric were later combined with BNFL in 1998, and eventually operated and managed by US-based EnergySolutions through its June 2007 acquisition of the BFNL subsidiary – Reactor Sites Management Company.[5]
The remaining two advanced "AGR" nuclear plant assets of the company were combined with the assets of Nuclear Electric; and became a part of the newly formed and soon to be privatised British Energy (now EDF Energy).[1][6][7]
Through the breakup, both the companies – Scottish Nuclear and Nuclear Electric became defunct; but is still extant through a descendant company – EDF Energy.
