United Kingdom Country in Europe

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world. The Irish Sea separates Great Britain and Ireland. The United Kingdom's 242,500 square kilometres (93,600 sq mi) were home to an estimated 66.0 million inhabitants in 2017.

Nuclear Decommissioning Authority non-departmental public body of the United Kingdom

The Nuclear Decommissioning Authority (NDA) is a non-departmental public body of the Department for Business, Energy and Industrial Strategy, formed by the Energy Act 2004. It evolved from the Coal and Nuclear Liabilities Unit of the Department of Trade and Industry. It came into existence during late 2004, and took on its main functions on 1 April 2005. Its purpose is to deliver the decommissioning and clean-up of the UK’s civil nuclear legacy in a safe and cost-effective manner, and where possible to accelerate programmes of work that reduce hazard. The NDA does not directly manage the UK's nuclear sites. It oversees the work through contracts with specially designed companies known as Site Licence Companies. The NDA determines the overall strategy and priorities for managing decommissioning.

Sellafield nuclear reprocessing site in Cumbria, England

Sellafield is a large nuclear fuel reprocessing, nuclear waste storage, nuclear decommissioning and former nuclear power generating site, close to Seascale on the coast of Cumbria, England. The site covers an area of two square miles and comprises more than 200 nuclear facilities and more than 1,000 buildings. It is Europe’s largest nuclear site and has the most diverse range of nuclear facilities in the world situated on a single site.

Magnox obsolete type of nuclear power reactor

Magnox is a type of nuclear power/production reactor that was designed to run on natural uranium with graphite as the moderator and carbon dioxide gas as the heat exchange coolant. It belongs to the wider class of gas cooled reactors. The name comes from the magnesium-aluminium alloy used to clad the fuel rods inside the reactor. Like most other "Generation I nuclear reactors", the Magnox was designed with the dual purpose of producing electrical power and plutonium-239 for the nascent nuclear weapons program in Britain. The name refers specifically to the United Kingdom design but is sometimes used generically to refer to any similar reactor.

British Nuclear Fuels Ltd former nuclear energy and fuels company owned by the UK Government

Dounreay is on the north coast of Caithness, in the Highland area of Scotland and west of the town of Thurso. Dounreay was originally the site of a castle and its name derives from the Gaelic for 'fort on a mound.' Since the 1950s it has been the site of two nuclear establishments, for the development of prototype fast breeder reactors and submarine reactor testing. Most of these facilities are now being decommissioned.

Nuclear decommissioning process whereby a nuclear power plant site is dismantled

Nuclear decommissioning is the process whereby a nuclear facility is dismantled to the point that it no longer requires measures for radiation protection. The presence of radioactive material necessitates processes that are potentially occupationally hazardous, expensive, time-intensive, and present environmental risks that must be addressed to ensure radioactive materials are either transported elsewhere for storage or stored on-site in a safe manner. The challenge in nuclear decommissioning is not just technical, but also economical and social.

Oldbury Nuclear Power Station
