Sellafield Sellafield Sellafield is a nuclear fuel reprocessing and nuclear decommissioning site, close to the village of Seascale on the coast of the Irish Sea in Cumbria, England. The site is served by Sellafield railway station. Sellafield incorporates the original nuclear reactor site at Windscale, which as of 2019 is undergoing decommissioning and dismantling, and Calder Hall, a neighbour of Windscale, which is also undergoing decommissioning and dismantling of its four nuclear power generating reactors. It is the site of the world's first commercial nuclear power station to generate electricity on an industrial scale. Sellafield was originally owned and operated by
Torness Nuclear Power Station AGR station. The construction, which was undertaken by a consortium known as National Nuclear Corporation ('NNC'), began in 1980. The reactors were supplied by NNC and the turbines by GEC. Torness was the last of the United Kingdom's second generation nuclear power plants to be commissioned (25 May 1988). The station consists of two advanced gas-cooled reactors (AGR) capable of producing a peak rating of 1364 MWe. Upon deregulation of the United Kingdom's electricity generation market it passed to the state-owned Scottish Nuclear, privatised as part of British Energy which was sold to the French company EDF in January 2009,
