 The combination process merged operations of UK's eight most advanced nuclear plants – seven Advanced Gas Cooled Reactor (AGR) and one Pressurised Water Reactor (PWR) – into a new private company founded in 1996, 'British Energy'.The splitting process created a separate company in 1996 called 'Magnox Electric' – which would hold a proportion of the old CEGB's nuclear stations, its older Magnox reactors.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 BNFL subsidiary – Reactor Sites Management Company.
