International Nuclear Services (INS) is a United Kingdom company involved in the management and transport of nuclear fuels. INS is based near Whitehaven, in Cumbria [1] and is operated by Nuclear Transport Solutions, a wholly owned subsidiary of the UK Government's Nuclear Decommissioning Authority (NDA).
INS began as the Spent Fuel Services division of British Nuclear Fuels (BNFL). As part of the restructuring of BNFL, 49% of the business was transferred to the NDA in 2006. It was renamed International Nuclear Services in 2007 and in April 2008, as BNFL was wound up, the NDA acquired the remaining 51% of INS. [2]
INS offers management, consultancy and transport services covering uranium, MOX fuel, irradiated fuel and nuclear waste. It also acts as the NDA's commercial arm, managing contracts for services provided from the NDA's Sellafield and Dounreay sites. As part of this role it works alongside the NDA's Direct Rail Services subsidiary, which transports nuclear materials in the UK by rail. [3]
INS conducts most of its transport operations through specialist nuclear materials shipping company Pacific Nuclear Transport Limited (PNTL), in which it has a controlling 62.5% stake. PNTL's remaining shares are owned by Areva (12.5%) and a consortium of Japanese nuclear companies (25%). PNTL's fleet is dedicated to carrying nuclear materials and transports most of its cargoes between Europe and Japan.
The fleet of three ships is managed by Serco, which also operates two ships for INS. [4] The vessels are armed for self-defence, and carry a contingent of the Civil Nuclear Constabulary on board to operate the armament.
An armed merchantman is a merchant ship equipped with guns, usually for defensive purposes, either by design or after the fact. In the days of sail, piracy and privateers, many merchantmen would be routinely armed, especially those engaging in long distance and high value trade.
Sellafield, formerly known as Windscale, is a large multi-function nuclear site close to Seascale on the coast of Cumbria, England. As of August 2022, primary activities are nuclear waste processing and storage and nuclear decommissioning. Former activities included nuclear power generation from 1956 to 2003, and nuclear fuel reprocessing from 1952 to 2022.
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 programme in Britain. The name refers specifically to the United Kingdom design but is sometimes used generically to refer to any similar reactor.
Great British Nuclear, officially British Nuclear Fuels Ltd is a nuclear energy and fuels company owned by the UK Government. It is a non-departmental public body sponsored by the Department for Energy Security and Net Zero.
Direct Rail Services (DRS) is a rail freight company in Great Britain, and is one of the publicly owned railway companies in the United Kingdom.
The United Kingdom Atomic Energy Authority is a UK government research organisation responsible for the development of fusion energy. It is an executive non-departmental public body of the Department for Energy Security and Net Zero (DESNZ).
Dounreay is a small settlement and the site of two large nuclear establishments on the north coast of Caithness in the Highland area of Scotland. It is on the A836 road nine miles west of Thurso.
Chapelcross nuclear power station is a former Magnox nuclear power station undergoing decommissioning. It is located in Annan in Dumfries and Galloway in southwest Scotland, and was in operation from 1959 to 2004. It was the sister plant to the Calder Hall nuclear power station plant in Cumbria, England; both were commissioned and originally operated by the United Kingdom Atomic Energy Authority. The primary purpose of both plants was to produce weapons-grade plutonium for the UK's nuclear weapons programme, but they also generated electrical power for the National Grid. Later in the reactors' lifecycle, as the UK slowed the development of the nuclear deterrent as the cold war came to a close, power production became the primary goal of reactor operation.
The Civil Nuclear Constabulary (CNC) is a special police force responsible for providing law enforcement and security at any relevant nuclear site and for security of nuclear materials in transit within the United Kingdom. The force has over 1,500 police officers and support staff. Officers within the force are authorised firearms officers due to the nature of the industry the force protects.
The Nuclear Decommissioning Authority (NDA) is a non-departmental public body of the Department for Energy Security and Net Zero 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.
Sellafield Ltd is a British nuclear decommissioning Site Licence Company (SLC) controlled by the Nuclear Decommissioning Authority (NDA), a UK government body set up specifically to deal with the nuclear legacy under the Energy Act 2004. From 2008–2016, it was operated under licence from the NDA by a third party Parent Body Organisation called Nuclear Management Partners (NMP). Since the termination of the NMP contract it has been brought back under direct governmental control by making it a subsidiary of the NDA.
The Thermal Oxide Reprocessing Plant, or THORP, is a nuclear fuel reprocessing plant at Sellafield in Cumbria, England. THORP is owned by the Nuclear Decommissioning Authority and operated by Sellafield Ltd.
EnergySolutions, headquartered in Salt Lake City, Utah, is one of the largest processors of low level waste (LLW) in America, making it also one of the world's largest nuclear waste processors. It was formed in 2007 when Envirocare acquired three other nuclear waste disposal companies: Scientech D&D, BNG America, and Duratek.
