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. [1]
From its creation in 1971 to 2010, it functioned as a manufacturer of nuclear fuel (notably MOX), ran reactors, generated and sold electricity, reprocessed and managed spent fuel (mainly at Sellafield), and decommissioned nuclear plants and other similar facilities.
It was resurrected in July 2023 under the trading name Great British Nuclear, to coordinate the UK nuclear industry to help achieve government net-zero targets. [2]
British Nuclear Fuels Limited (BNFL) was set up in February 1971 from the demerger of the production division of the UK Atomic Energy Authority (UKAEA). In 1984, BNFL became a public limited company as British Nuclear Fuels plc, wholly owned by the UK government.
Its US subsidiary BNFL, Inc. was established in 1990 and specialised in decontamination and decommissioning of nuclear sites.
In 1996, seven advanced gas-cooled reactors (AGR) and one pressurised water reactor (PWR) were privatised as British Energy, raising £2.1 billion. [3] The oldest reactors, the Magnox sites, were not attractive for commercial operations and remained in public ownership as Magnox Electric. On 30 January 1998, Magnox Electric was merged into BNFL as BNFL Magnox Generation. [4] [5]
In 1999, it was discovered that BNFL staff had been falsifying some MOX fuel quality assurance data since 1996. [6] A Nuclear Installations Inspectorate (NII) investigation concluded that "the level of control and supervision ... had been virtually non-existent." [7] BNFL had to pay compensation to the Japanese customer, Kansai Electric, and take back a flawed shipment of MOX fuel from Japan. [8] BNFL's Chief Executive John Taylor resigned, [9] after initially resisting resignation when the NII's damning report was published. [10] [11]
As a consequence of this crisis, a possible partial privatisation of BNFL was delayed by two years. [12] [13] [14]
In 1999, BNFL acquired Westinghouse Electric Company, the commercial nuclear power businesses of CBS (Westinghouse acquired CBS in 1995 and reoriented itself as a broadcaster), for $1.1 billion. Westinghouse's businesses are fuel manufacture, decommissioning of nuclear sites and reactor design, construction and servicing. [15] Westinghouse was acquired as a possible core for the privatisation of a portion of BNFL. [16]
In 2000, BNFL also purchased the nuclear businesses of ABB for £300 million. This company, which was merged into Westinghouse, had nuclear interests in the United States, Europe and Asia. [17] In June 2000, BNFL took a 22.5% stake in Pebble Bed Modular Reactor (Pty) Ltd in South Africa. [18]
In January 2003, the research and development arm of BNFL was relaunched as Nuclear Sciences and Technology Services (NSTS).
However, BNFL's financial difficulties increased, and the prospect of partial privatisation diminished. [16] [19] [20]
On 1 April 2005, the company was reorganised as part of the restructuring of the wider nuclear industry. BNFL became British Nuclear Group (BNG) and a new holding company was established and adopted the British Nuclear Fuels name. [21] This new BNFL operated largely through its major subsidiaries of Westinghouse and BNG as well as Nexia Solutions, its commercial nuclear technology business formed out of NSTS. [22]
The Nuclear Decommissioning Authority (NDA) was established on 1 April 2005 and took ownership of all of BNFL's nuclear sites, including the Sellafield site. The NDA then opened up the decommissioning of the different sites to tender to drive down costs. BNFL became one of a number of decommissioning contractors through BNG. BNFL's nuclear waste transfer companies, Direct Rail Services and International Nuclear Services, were also both transferred to the NDA. [23]
On 19 April 2005, BNFL, Inc. was renamed BNG America and made a subsidiary of BNG. [24]
In July 2005, BNFL confirmed it planned to sell Westinghouse, then estimated to be worth $1.8bn (£1bn). However the bid attracted interest from several companies, including Toshiba, General Electric and Mitsubishi Heavy Industries and when the Financial Times reported on 23 January 2006 that Toshiba had won the bid, it valued the company's offer at $5bn (£2.8bn). [25] On 6 February 2006, Toshiba confirmed it was buying Westinghouse Electric Company for $5.4bn and announced it would sell a minority stake to investors. [15] [26]
On 3 February 2006, BNFL announced it had agreed to sell BNG America to Envirocare to form EnergySolutions. [27]
In March 2006, BNFL announced its intention to sell BNG. With the sale of Westinghouse, BNG America and BNG this was to effectively bring BNFL to an end. Mike Parker, CEO of BNFL, said: "By the end of 2007... there will be little need for the BNFL corporate centre from this time". [28] On 22 August 2006, BNFL announced that instead of selling BNG as a going concern it would instead sell it off piece by piece. [29]
In January 2007, BNFL announced that it would sell BNG's Magnox reactor sites operating business, Reactor Sites Management Company Ltd. [30] It was later sold in June 2007, along with its subsidiary that held the operating contracts with the NDA, Magnox Electric, to EnergySolutions. [31] [32] All UK Magnox power stations were due to cease operation by the end of 2015.
BNG Project Services, BNG's specialist nuclear consulting business, was sold in January 2008 to VT Group, which was itself later acquired in 2010 by Babcock International Group.[ citation needed ]
BNG was renamed Sellafield Ltd and became the NDA's Site Licence Company (SLC) for the decommissioning contract at Sellafield. In November 2008, the NDA contracted the management of Sellafield Ltd to Nuclear Management Partners Ltd, a consortium of URS, AMEC and Areva. [33]
In July 2006, the UK Government stated its intention to preserve and develop key research and development capabilities potentially as part of a National Nuclear Laboratory (NNL). In October 2006, Secretary of State for Trade and Industry, Alistair Darling confirmed the NNL would be formed out of Nexia Solutions and the British Technology Centre at Sellafield. [34] The NNL was launched in July 2008 as a Government-owned company, and initially was managed under contract by a consortium of Serco, Battelle and the University of Manchester; this is known as a GOCO (Government-Owned, Contractor-Operated) arrangement. [35]
Control of BNFL's one third stake in Urenco was transferred to the Shareholder Executive in April 2008 through Enrichment Holdings Ltd while the government explored the possibility of selling the stake. [36]
BNFL's one third stake of AWE Management Ltd was sold to Jacobs Engineering Group in December 2008. [37] AWE is responsible for the support and manufacturing of the UK's nuclear deterrent.
As BNFL was wound down it was converted back to a private limited company on 31 December 2008 and regained its original name, British Nuclear Fuels Limited. [38] The final sale transactions for BNFL's former businesses were completed in May 2009.
Despite this, the company itself was not wound up and continued as a legal entity. [39]
In February 2023, plans to wind up the company within two years were still active. By this point the company had not traded in 13 years. [40]
However, on 18 July 2023, BNFL was resurrected as Great British Nuclear, with the aim of delivering the government's long-term nuclear programme and supporting its ambition to deliver up to 24 GW of nuclear power in the UK by 2050. [2]
GBN is led by Gwen Parry-Jones as interim chief executive officer, who is also the CEO of Magnox Ltd. [41]
Its chair is Simon Bowen. [42]
BNFL formerly had operations at 18 sites in the UK:
The former BNFL logotype was created in 1996 by Lloyd Northover, the British design consultancy founded by John Lloyd and Jim Northover.
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.
Westinghouse Electric Company LLC is an American nuclear power company formed in 1999 from the nuclear power division of the original Westinghouse Electric Corporation. It offers nuclear products and services to utilities internationally, including nuclear fuel, service and maintenance, instrumentation, control and design of nuclear power plants. Westinghouse's world headquarters are located in the Pittsburgh suburb of Cranberry Township, Pennsylvania. Brookfield Business Partners, a Canadian private equity fund and a subsidiary of Brookfield Asset Management is the majority owner of Westinghouse.
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.
The Dungeness nuclear power stations are a pair of non-operational nuclear power stations located on the Dungeness headland in the south of Kent, England.
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 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.
Wylfa nuclear power station is a Magnox nuclear power station undergoing decommissioning. Wylfa is situated west of Cemaes Bay on the island of Anglesey, off the northwestern coast of Wales. Construction of the two 490 MW nuclear reactors, known as Reactor 1 and Reactor 2, began in 1963. They became operational in 1971. Wylfa was located on the coast because seawater was used as a coolant.
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.
The Magnox Reprocessing Plant is a former nuclear reprocessing facility at Sellafield in northern England, which operated from 1964 to 2022. The plant used PUREX chemistry to extract plutonium and uranium from used nuclear fuel originating primarily from Magnox reactors. The plant was originally constructed and operated by the United Kingdom Atomic Energy Authority (UKAEA), but in 1971 control was transferred to British Nuclear Fuels Limited (BNFL). Since 2005 the plant has been 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.
Nuclear power in the United Kingdom generated 16.1% of the country's electricity in 2020. As of August 2022, the UK has 9 operational nuclear reactors at five locations, producing 5.9 GWe. It also has nuclear reprocessing plants at Sellafield and the Tails Management Facility (TMF) operated by Urenco in Capenhurst.
The Sizewell nuclear site consists of two nuclear power stations, one of which is still operational, located near the small fishing village of Sizewell in Suffolk, England. Sizewell A, with two Magnox reactors, is now in the process of being decommissioned. Sizewell B has a single pressurised water reactor (PWR) and is the UK's newest nuclear power station. A third power station, to consist of twin EPR reactors, is planned to be built as Sizewell C.
Oldbury nuclear power station is a Magnox nuclear power station undergoing decommissioning. It is located on the south bank of the River Severn close to the village of Oldbury-on-Severn in South Gloucestershire, England. The ongoing decommissioning process is managed by Magnox Ltd, a subsidiary of the Nuclear Decommissioning Authority (NDA).
Hunterston A nuclear power station is a former Magnox nuclear power station located at Hunterston in Ayrshire, Scotland, adjacent to Hunterston B. The ongoing decommissioning process is being managed by Nuclear Decommissioning Authority (NDA) subsidiary Magnox Ltd.
Springfields is a nuclear fuel production installation in Salwick, near Preston in Lancashire, England. The site is currently operated by Springfields Fuels Limited, under the management of Westinghouse Electric UK Limited, on a 150-year lease from the Nuclear Decommissioning Authority. Since its conversion from a munitions factory in 1946, it has previously been operated and managed by a number of different organisations including the United Kingdom Atomic Energy Authority and British Nuclear Fuels. Fuel products are produced for the UK's nuclear power stations and for international customers.
Trawsfynydd nuclear power station is a former Magnox nuclear power station situated in Snowdonia National Park in Gwynedd, Wales. The plant, which became operational in 1965, was the only nuclear power station in the UK to be built inland, with cooling water that was taken from the man-made Llyn Trawsfynydd reservoir which also supplies the hydro-electric Maentwrog power station. It was closed in 1991. Its ongoing decommissioning by Magnox Ltd was expected to take almost 100 years, but in 2021 the Welsh government arranged for the power station to be redeveloped using small-scale reactors.
Magnox Ltd is a British nuclear decommissioning Site Licence Company (SLC) under the Nuclear Decommissioning Authority (NDA), a UK government body set up specifically to deal with the nuclear legacy under the Energy Act 2004. In September 2019, it became a direct subsidiary of the NDA.
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 and is operated by Nuclear Transport Solutions, a wholly owned subsidiary of the UK Government's Nuclear Decommissioning Authority (NDA).
Calder Hall Nuclear Power Station is a former Magnox nuclear power station at Sellafield in Cumbria in North West England. Calder Hall was the world's first full-scale commercial nuclear power station to enter operation, and was the sister plant to the Chapelcross plant in Scotland. 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.
