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 July 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 nuclear power station to generate electricity on an industrial scale.

Ownership and facilities

Sellafield was originally owned and operated by the Ministry of Supply (MoS), then from 1954 by the United Kingdom Atomic Energy Authority (UKAEA) and subsequently, following the division of UKAEA in 1971, by British Nuclear Fuels Ltd (BNFL). Since 1 April 2005, it has been owned by the Nuclear Decommissioning Authority (NDA) and is now operated by Sellafield Ltd.

In 2008, the NDA awarded Nuclear Management Partners (NMP) the position of Parent Body Organisation of Sellafield Ltd. under their standard management model for NDA sites. This consortium, composed of US company URS, British company AMEC, and Areva of France, was initially awarded a contract for five years, with extension options to 17 years.[1]

On 13 January 2015, the NDA announced that NMP would lose the management contract for Sellafield Ltd. as the "complexity and technical uncertainties presented significantly greater challenges than other NDA sites", and the site was therefore "less well suited" to the NDA's existing standard management model.[2] The new structure, which came into effect on 1 April 2016, saw Sellafield Ltd. become a subsidiary of the NDA.

Activities at the Sellafield site primarily support decommissioning of historic plants, and reprocessing fuel from UK and international nuclear reactors. Decommissioning projects include the Windscale Piles,[3] Calder Hall, historic reprocessing facilities, waste stores, as well as other clean-up projects on the site. Reprocessing plants include the THORP nuclear fuel reprocessing plant, the Magnox nuclear fuel reprocessing plant, and the Waste Vitrification Plant. The site contains several nuclear waste stores, with the Low Level Waste Repository 6 km away at Drigg. The UK's National Nuclear Laboratory also has its Central Laboratory on the Sellafield site.


Sellafield was a small rural community situated on the west (Irish Sea) coast of North-West England in the current county of Cumbria (and formerly in the pre-1974 county of Cumberland) in the parish of St Bridget Beckermet between the rivers Calder and Ehen. It consisted of High Sellafield (to the north, and which still exists) and Low Sellafield, which became incorporated in the Sellafield Royal Ordnance Factory (ROF) during its construction in the Second World War. The coming of the railway to west Cumberland in the mid-19th century, and the opening of Sellafield station and Sellafield junction (for the branch line to Beckermet and Egremont, Cumbria), provided important transport links for a remote part of England.

ROF Sellafield was constructed by John Laing & Son in 1942[4] at Low Sellafield as a Second World War ROF.[5] The nearby sister factory, ROF Drigg which produced TNT (trinitrotoluene) had been constructed in 1940, 5 km to the south-east and adjacent to the village of Drigg.[6] ROF Drigg and ROF Sellafield were built in these isolated and remote coastal sites because of the hazardous nature of the process and to minimise the risk of enemy air attack. They were both classed as Explosive ROFs specialising in high-explosive TNT (ROF Drigg) and propellant (ROF Sellafield), and production ceased at both factories immediately following the defeat of Japan.

After the war, the Sellafield site was briefly in the ownership of Courtaulds for development as a factory, but was reacquired by the Ministry of Supply to adapt the site for the production of materials for nuclear weapons, principally plutonium. Construction of the nuclear facilities commenced in September 1947. The site was renamed Windscale Works (after Windscale Nook, a bluff on the north bank of the River Calder) to avoid confusion with the Springfields uranium processing factory near Preston. The building of the nuclear plants at Windscale Works was a huge construction project, requiring a peak of 5,000 workers. The two air-cooled and open-circuit, graphite-moderated Windscale reactors (the "Windscale Piles") constituted the first British weapons grade plutonium-239 production facility, built for the British nuclear weapons programme of the late 1940s and the 1950s. Windscale Pile No. 1 was operational in October 1950 (just over three years from the start of construction at Sellafield), and Pile No. 2 in June 1951. Pile 1 was the site in 1957 of the Windscale fire, the worst nuclear accident in UK history, ranked in severity at level 5 out of a possible 7 on the International Nuclear Event Scale.

Windscale was later also the site of the prototype British advanced gas-cooled reactor.

The site in 1956

With the creation of the United Kingdom Atomic Energy Authority (UKAEA) in 1954, ownership of Windscale Works passed to the UKAEA. The first of four Magnox reactors became operational in 1956 at Calder Hall, adjacent to Windscale and across the River Calder, and the site became Windscale and Calder Works. Following the break-up of the UKAEA into a research division (UKAEA) and a production division, British Nuclear Fuels Ltd (BNFL) in 1971, the major part of the site was transferred to BNFL. In 1981 BNFL's Windscale and Calder Works was renamed Sellafield as part of a major reorganisation of the site – up to that time there was a General Manager of Windscale Works and a General Manager of Calder Works, but afterwards there was one Head of the entire BNFL Sellafield site – as well as to possibly attempt to disassociate the site from press reports about its safety. The remainder of the site remained in the hands of the UKAEA and was still called Windscale.[7]

Since its inception as a nuclear facility, Sellafield has also been host to reprocessing operations, which separate the uranium, plutonium, and fission products from spent nuclear fuel.[8] The uranium can then be used in the manufacture of new nuclear fuel, or in applications where its density is an asset. The plutonium can be used in the manufacture of mixed oxide fuel (MOX) for thermal reactors, or as fuel for fast breeder reactors, such as the Prototype Fast Reactor at Dounreay. These processes, including the associated cooling ponds, require considerable amounts of water and the licence to extract water from Wast Water, formerly held by BNFL, is now held by the Nuclear Decommissioning Authority.

On 19 April 2005, leaked radioactive waste was discovered from ThORP (Thermal Oxide reprocessing plant) through a crack into a sump chamber which may have started as early as August 2004, and was categorised as a level 3 event on the International Nuclear Event Scale, resulting in fines.

In February 2009, NuGeneration (NuGen), a consortium of GDF Suez, Iberdrola and Scottish and Southern Energy (SSE), announced plans to build a new nuclear power station of up to 3.6GW capacity at Sellafield. In October 2009, NuGen purchased an option to acquire land around Sellafield from the NDA for £70m.[9]

On 2 June 2010, Sellafield's gates were closed as a precaution in the wake of a deadly shooting spree and subsequent police manhunt, and the afternoon shift was told not to come to work. This was the first lock-down in the history of the plant.[10]

On 18 October 2010, the UK government announced that Sellafield was one of the eight possible sites it considered suitable for future nuclear power stations.[11] On 23 June 2011 the government confirmed the suitability of the site, and hoped an electricity generating company would choose to build a power station near Sellafield at Moorside by 2025.[12]

In 2003, it was announced that the Thorp reprocessing plant would be closed in 2010 (later extended to 2018 to allow completion of agreed contracts). Originally predicted to make profits for BNFL of £500m, by 2003 it had made losses of over £1bn.[15] Subsequently, Thorp was closed for almost two years from 2005, after a leak had been undetected for 9 months. Production eventually restarted at the plant in early 2008; but almost immediately had to be put on hold again, for an underwater lift that takes the fuel for reprocessing to be repaired.[16]

In November 2008, Sellafield was taken over by a new consortium (US company URS Corp., Areva and the UK company Amec) for decommissioning, as part of a 5-year £6.5bn contract. In October 2008 it was revealed that the British government had agreed to issue Sellafield an unlimited indemnity against future accidents; according to The Guardian, "the indemnity even covers accidents and leaks that are the consortium's fault." The indemnity had been rushed through prior to the summer parliamentary recess without notifying parliament.[17]

In 2009, Sellafield decommissioning accounted for 40% of the annual budget of the Nuclear Decommissioning Authority – over £1.1bn.[18]

In 2013, a critical Public Accounts Committee report stated that the private consortium managing Sellafield has failed to reduce costs and delays. Between 2005 and 2013 the annual costs of operating Sellafield increased from £900 million to about £1.6 billion. The estimated lifetime undiscounted cost of dealing with the Sellafield site increased to £67.5 billion.[19][20][21] Bosses were forced to apologise after projected clean-up costs passed the £70 billion mark in late 2013.[22] In 2014, the undiscounted decommissioning cost estimate for Sellafield was increased to £79.1 billion,[23] and by 2015 to £117.4 billion.[14] The annual operating cost will be £2 billion in 2016.[24]

Major plants

Windscale Piles

Storm Clouds over Sellafield - - 330062
The Windscale Piles (centre and right)

Following the decision taken by the British government in January 1947 to develop nuclear weapons, Sellafield was chosen as the location of the plutonium production plant, consisting of the Windscale Piles and accompanying reprocessing plant to separate plutonium from the spent nuclear fuel. Unlike the early US nuclear reactors at Hanford, which consisted of a graphite core cooled by water, the Windscale Piles consisted of a graphite core cooled by air. Each pile contained almost 2,000 tonnes (1,968 L/T) of graphite, and measured over 7.3 metres (24 ft) high by 15.2 metres (50 ft) in diameter. Fuel for the reactor consisted of rods of uranium metal, approximately 30 centimetres (12 in) long by 2.5 centimetres (1 in) in diameter, and clad in aluminium.[25] The initial fuel was loaded into the Windscale Piles in July 1950.[26][27] By July 1952 the separation plant was being used to separate plutonium and uranium from spent fuel.

On 10 October 1957, the Windscale Piles were shut down following a fire in Pile 1 during a routine maintenance check, which destroyed the core and released an estimated 750 terabecquerels (20,000 curies) of radioactive material, including 22 TBq of Cs-137 and 740 TBq of I-131 into the shafts.[28] Thanks to innovative filters installed by Nobel laureate Sir John Cockcroft 95% of the material was captured.[29] As a precautionary measure, milk from surrounding farming areas was destroyed. Following the fire, Pile 1 was unserviceable, and Pile 2, although undamaged by the fire, was shut down as a precaution.[25]

In the 1990s, the United Kingdom Atomic Energy Authority started to implement plans to decommission, disassemble and clean up both piles. In 2004 Pile 1 still contained about 15 tonnes (14.76 L/T) of uranium fuel, and final completion of the decommissioning is not expected until at least 2037.[25]

In 2014, radioactive sludge in the Pile Fuel Storage Pond (PFSP), built between 1948 and 1952, started to be repackaged in drums to reduce the "sludge hazard" and to allow the pond to be decommissioned.[30][31] Decommissioning will require retrieval of sludge and solids, prior to dewatering and deconstruction, with retrievals planned for completion in 2016.[32]

First Generation Reprocessing Plant

The first generation reprocessing plant was built to extract the plutonium from spent fuel to provide fissile material for the UK's atomic weapons programme, and for exchange with the United States through the US-UK Mutual Defence Agreement.

It operated from 1951 until 1964, with an annual capacity of 300 tonnes (295 L/T) of fuel, or 750 tonnes (738 L/T) of low burn-up fuel. It was first used to reprocess fuel from the Windscale Piles, and was later repurposed to process fuel from UK Magnox reactors, however following the commissioning of the dedicated Magnox Reprocessing Plant, it was itself recycled to become a pre-handling plant to allow oxide fuel to be reprocessed in the Magnox plant, and was closed in 1973.[33]

Magnox Reprocessing Plant

In 1964 the Magnox reprocessing plant came on stream to reprocess spent nuclear fuel from the Magnox reactors.[34] The plant uses the "plutonium uranium extraction" Purex method for reprocessing spent fuel, with tributyl phosphate in odourless kerosene and nitric acid as extraction agents. The Purex process produces uranium, plutonium and fission products as output streams.

Over the 30 years from 1971 to 2001 the Magnox Reprocessing Plant has reprocessed over 35,000 tonnes of Magnox fuel, with 15,000 tonnes of fuel being regenerated.[35] Magnox fuel is reprocessed since it corrodes if stored underwater, and routes for dry storage have not yet been proven.[36]

First Generation Magnox Storage Pond (FGMSP)

The FGMSP was built to support reprocessing of fuel from UK Magnox power stations through the First Generation Reprocessing Plant, and was used for operations between 1960 until 1986. The pond is 20m wide, 150m long and 6m deep. A confinement wall is scheduled to be built in the future to help it withstand earthquakes.

As of 2014, the First Generation Magnox Storage Pond (FGMSP) remains as a priority decommissioning project. As well as nuclear waste, the pond holds about 1,200 cubic metres of radioactive sludge of unknown characteristics and 14,000 cubic metres of contaminated water.[37] Decommissioning initially requires retrieval of the radioactive sludge into a newly built Sludge Packaging Plant 1, as well as fuel and skip retrieval. Completion of this will allow the dewatering and dismantling of the remaining structure. Future work will immobilise the sludge for long-term storage, and process solids through the Fuel Handling Plant for treatment and storage.[38]

Calder Hall nuclear power station

Calder Hall nuclear power station (11823864155)
Calder Hall, United Kingdom - The world's first commercial nuclear power station.[39] First connected to the national power grid on 27 August 1956 and officially opened by Queen Elizabeth II on 17 October 1956
Calder Hall Reactor No.4

Calder Hall, first connected to the grid on 27 August 1956 and officially opened by Queen Elizabeth II on 17 October 1956,[40][41] was the world's first power station to generate electricity on an industrial scale (four 60 MWe reactors) from nuclear energy;[42] a 5 MWe experimental reactor at Obninsk in the Soviet Union had been connected to the public supply in 1954,[43][44] and was the world's first nuclear power plant.[45] The Calder Hall design was codenamed PIPPA (Pressurised Pile Producing Power and Plutonium) by the UKAEA to denote the plant's dual commercial and military role. Construction started in 1953.[46] Calder Hall had four Magnox reactors capable of generating 60 MWe (net) of power each, reduced to 50 MWe in 1973.[47][48] The reactors also supplied steam to the whole site for process and other purposes. The reactors were supplied by UKAEA, the turbines by C. A. Parsons and Company,[48] and the civil engineering contractor was Taylor Woodrow Construction.[49] When the station closed on 31 March 2003, the first reactor had been in use for nearly 47 years.[50]

In its early life Calder Hall primarily produced weapons-grade plutonium, with two fuel loads per year; electricity production was a secondary purpose.[51] From 1964 it was mainly used on commercial fuel cycles; in April 1995 the UK Government announced that all production of plutonium for weapons purposes had ceased.

Cooling towers

Calder Hall had four cooling towers, built in 1950–56 to cool the water from the station. The towers were 88 metres in height and used the natural draught hyperboloid design. The towers stood for 50 years, creating a landmark visible from the village of Seascale. Plans for a museum involving renovating Calder Hall and preserving the towers were formulated, but the costs were too high. The cooling towers were demolished by controlled implosions on 29 September 2007, by Controlled Demolition, Inc. A period of 12 weeks was required to remove asbestos in the towers' rubble.[52]

Windscale Advanced Gas Cooled Reactor (WAGR)

The WAGR[53] was a prototype for the UK's second generation of reactors, the advanced gas-cooled reactor or AGR, which followed on from the Magnox stations. The station had a rated thermal output of approximately 100MW and 30 MW electrical. The WAGR golfball is, along with the pile chimneys, one of the iconic buildings on the Windscale site (Windscale being an independent site within the Sellafield complex). Construction was carried out by Mitchell Construction and completed in 1962.[54] This reactor was shut down in 1981, and is now part of a pilot project to demonstrate techniques for safely decommissioning a nuclear reactor.

Thermal Oxide Reprocessing Plant

Between 1977 and 1978 an inquiry was held into an application by BNFL for outline planning permission to build a new plant to reprocess irradiated oxide nuclear fuel from both UK and foreign reactors. The inquiry was used to answer three questions:

"1. Should oxide fuel from United Kingdom reactors be reprocessed in this country at all; whether at Windscale or elsewhere?
2. If yes, should such reprocessing be carried on at Windscale?
3. If yes, should the reprocessing plant be about double the estimated site required to handle United Kingdom oxide fuels and be used as to the spare capacity, for reprocessing foreign fuels?"

The result of the inquiry was that the new plant, the Thermal Oxide Reprocessing Plant (THORP) was given the go ahead in 1978, although it did not go into operation until 1994. On 14 November 2018 it was announced that operations had ended at THORP. The facility will be used to store spent nuclear fuel until the 2070s.[56]

2005 THORP plant leak

On 19 April 2005 83,000 litres of radioactive waste was discovered to have leaked in the THORP reprocessing plant from a cracked pipe into a huge stainless steel-lined concrete sump chamber built to contain leaks.

A discrepancy between the amount of material entering and exiting the THORP processing system had first been noted in August 2004. Operations staff did not discover the leak until safeguards staff reported the discrepancies. 19 tonnes of uranium and 160 kilograms of plutonium dissolved in nitric acid has been pumped from the sump vessel into a holding tank.[57]

No radiation was released to the environment, and no one was injured by the incident, but because of the large escape of radioactivity to the secondary containment the incident was given an International Nuclear Event Scale level 3 categorisation.

Sellafield Limited was fined £500,000 for breaching health and safety law. In January 2007 Sellafield was given consent to restart THORP.[57]

Highly Active Liquor Evaporation and Storage

Highly Active Liquor Evaporation and Storage (HALES) is a department at Sellafield.

It conditions nuclear waste streams from the Magnox and Thorp reprocessing plants, prior to transfer to the Waste Vitrification Plant.

Waste Vitrification Plant

In 1991 the Waste Vitrification Plant (WVP), which seals high-level radioactive waste in glass, was opened. In this plant, liquid wastes are mixed with glass and melted in a furnace, which when cooled forms a solid block of glass.

The plant has three process lines and is based on the French AVM procedure. Principal item is an inductively heated melting furnace, in which the calcined waste is merged with glass frit (glass beads of 1 to 2 mm in diameter). The melt is placed into waste containers, which are welded shut, their outsides decontaminated and then brought into air-cooled storage facilities. This storage consists of 800 vertical storage tubes, each capable of storing ten containers. The total storage capacity is 8000 containers, and 5000 containers have been stored to 2010. Vitrification should ensure safe storage of waste in the UK for the middle to long term.

Sellafield MOX Plant

Construction of the Sellafield MOX Plant (SMP) was completed in 1997, though justification for the operation of the plant was not achieved until October 2001.[58] Mixed oxide, or MOX fuel, is a blend of plutonium and natural uranium or depleted uranium which behaves similarly (though not identically) to the enriched uranium feed for which most nuclear reactors were designed. MOX fuel is an alternative to low enriched uranium (LEU) fuel used in the light water reactors which predominate in nuclear power generation. MOX also provides a means of using excess weapons-grade plutonium (from military sources) to produce electricity.

Designed with a plant capacity of 120 tonnes/year, it achieved a total output of only 5 tonnes during its first five years of operation.[58] In 2008 orders for the plant had to be fulfilled at COGEMA in France,[59] and the plant was reported in the media as "failed"[60][61] with a total construction and operating cost of £1.2 billion.[62]

On 12 May 2010 an agreement was reached with existing Japanese customers on future MOX supplies.[63] In July 2010 Areva was contracted to design and supply a new rod line to improve reliability and production rate.

On 3 August 2011 the Nuclear Decommissioning Authority announced that the MOX Plant would close, due to the loss of Japanese orders following the Fukushima Daiichi nuclear disaster.[64] Japanese orders for MOX recommenced on 17 April 2013, being supplied by the Sellafield MOX plant's main competitor, the French MOX fuel vendor COGEMA owned by Areva.[65]

Enhanced Actinide Removal Plant

Since its early days, Sellafield has discharged low-level radioactive waste into the sea, using a flocculation process to remove radioactivity from liquid effluent before discharge. Metals dissolved in acidic effluents produced a metal hydroxide flocculant precipitate following the addition of ammonium hydroxide. The suspension was then transferred to settling tanks where the precipitate would settle out, and the remaining clarified liquid, or supernate, would be discharged to the Irish Sea.

In 1994 the Enhanced Actinide Removal Plant (EARP) was opened. In EARP the effectiveness of the process is enhanced by the addition of reagents to remove the remaining soluble radioactive species. EARP was enhanced in 2004 to further reduce the quantities of technetium-99 released to the environment.[66]

Radioactive waste stores

Sellafield has several radioactive waste stores, mostly on an interim basis while a national waste repository plan is developed and implemented. The stores include: [67]

  • Legacy Ponds and Silos – Storage of historic waste
  • Sludge packaging plant – Treatment and interim storage of sludges from legacy ponds
  • Sellafield product and residue store – Site store for plutonium and plutonium residues – The plutonium stockpile now estimated (November 2013) at 100 tonnes.[68]
  • Engineered drum stores – Site stores for plutonium contaminated material
  • Encapsulated product stores – Site stores for grouted wastes
  • Vitrified product store – Vitrified high level waste

The UK's main Low Level Waste Repository for nuclear waste is 6 kilometres (3.7 mi) south east of Sellafield at Drigg. A paper published in 1989 said that 70% of the waste received at Drigg originated from Sellafield.[69]

Fellside Power Station

Fellside Power Station is a 168 MWe CHP gas-fired power station near the Sellafield site, which it supplies with steam and heat. It is run as Fellside Heat and Power Ltd, is wholly owned by Sellafield Ltd and is operated & managed by PX Ltd. It was built in 1993, being originally equally owned by BNFL and Scottish Hydro Electric (which became Scottish and Southern Energy in December 1998).

The station uses three General Electric Frame 6001B gas turbines, with power entering the National Grid via a 132kV transformer. The turbines in Fellside Power Station are natural gas fired and are also able to run on distillate (diesel) fuel. BNFL bought SSE's 50% share in January 2002.[70]

Sellafield and the local community

Sellafield directly employs around 10,000 people[71] and is one of the two largest non-governmental employers in West Cumbria (along with BAE Systems at Barrow-in-Furness),[72] with approximately 90% of the employees coming from West Cumbria.[73]

Because of the increase in local unemployment following any run down of Sellafield operations, the Nuclear Decommissioning Authority (and HMG) is concerned that this needs to be managed.[74]

Central Laboratory – National Nuclear Laboratory headquarters

The Central Laboratory at Sellafield is the headquarters of the National Nuclear Laboratory and is the flagship nuclear Research and Development facility in the UK. It supports newly built reactors, operation of reactors, operations of fuel processing plants and decommissioning and clean-up. The NNL's Central Laboratory is available to run a wide range of radioactive and non-radioactive experimental programmes.

In addition, it offers a wide range of analytical services, building on its location on the Sellafield site and considerable expertise of its resident technologists. Customers range from Government and the NDA to site licence companies, utilities, nuclear specialists and universities. The facility has been designed with flexibility and collaboration firmly at its heart. Smaller experiments can be easily set, taking advantage of the modular nature of the laboratories. Larger experiments and rigs can be assembled off site, installed and pre-tested in non-radioactive areas prior to active testing.

Sellafield Centre – Business and Information Centre

Sellafield Visitors' Centre
Sellafield Visitors' Centre

At its peak, the Sellafield Visitors' Centre attracted an average of 1,000 people per day. In recent years, its popularity deteriorated, prompting the change from tourist attraction to conference facility.

It is now the Business and Information Centre and is open Mon – Fri only. The centre is used for business events such as supplier forums and 'Meet the Buyer' events. The Visitors Centre is completely closed, and there are no areas for the public to visit.

Radiological releases

Between 1950 and 2000 there were 21 serious incidents or accidents involving off-site radiological releases that warranted a rating on the International Nuclear Event Scale, one at level 5, five at level 4 and fifteen at level 3. Additionally during the 1950s and 1960s there were protracted periods of known, deliberate discharges to the atmosphere of plutonium and irradiated uranium oxide particulates.[75] These frequent incidents, together with the large 2005 THORP plant leak which was not detected for nine months, have led some to doubt the effectiveness of the managerial processes and safety culture on the site over the years.

In the effort to build an independent British nuclear weapon in the 1940s and 1950s, the Sellafield plant was constructed; diluted radioactive waste was discharged by pipeline into the Irish Sea.[76] Greenpeace claims that the Irish Sea remains one of the most heavily contaminated seas in the world because of these discharges.[77] Ocean scientist David Assinger has challenged this general suggestion, and cites the Dead Sea as the most radioactive sea in the world.[78] The Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR Convention) reports an estimated 200 kilograms (441 lb) of plutonium has been deposited in the marine sediments of the Irish Sea.[79] Cattle and fish in the area have been contaminated with plutonium-239 and caesium-137 from these sediments and from other sources such as the radioactive rain that fell on the area after the Chernobyl disaster. Most of the area's long-lived radioactive technetium comes from the reprocessing of spent nuclear fuel at the Sellafield facility.[80]

Technetium-99 is a radioactive element which is produced by nuclear fuel reprocessing, and also as a by-product of medical facilities (for example Ireland is responsible for the discharge of approximately 11 grams or 6.78 gigabecquerels of technetium-99 each year despite not having a nuclear industry).[81] Because it is almost uniquely produced by nuclear fuel reprocessing, technetium-99 is an important element as part of the OSPAR Convention since it provides a good tracer for discharges into the sea.

In itself, the technetium discharges do not represent a significant radiological hazard,[82] and recent studies have noted "...that in the most recently reported dose estimates for the most exposed Sellafield group of seafood consumers (FSA/SEPA 2000), the contributions from technetium-99 and actinide nuclides from Sellafield (<100 µSv) was less than that from 210Po attributable to discharges from the Whitehaven phosphate fertilizer plant and probably less than the dose from naturally occurring background levels of 210Po."[83] Because of the need to comply with the OSPAR Convention, British Nuclear Group (the licensing company for Sellafield) has recently commissioned a new process in which technetium-99 is removed from the waste stream and vitrified in glass blocks.[84]

Discharges into the sea of radioactive effluents – mainly caesium-137 – from Sellafield amounted to 5200 TBq during the peak year, 1975.[85]

There has been concern that the Sellafield area will become a major dumping ground for unwanted nuclear material, since there are currently no long-term facilities for storing High-Level Waste (HLW), although the UK has current contracts to reprocess spent fuel from all over the world. Contracts agreed since 1976 between BNFL and overseas customers require that all HLW be returned to the country of origin. The UK retains low- and intermediate-level waste resulting from its reprocessing activity, and instead ships out a radiologically equivalent amount of its own HLW. This substitution policy is intended to be environmentally neutral and to speed return of overseas material by reducing the number of shipments required, since HLW is far less bulky.[86]

1983 was the year of the "Beach Discharge Incident" in which high radioactive discharges containing ruthenium and rhodium-106, both beta-emitting isotopes, resulted in the closure of beaches along a 10-mile (16 km) stretch of coast between St. Bees and Eskmeals, along with warnings against swimming in the sea.[87][88] BNFL received a fine of £10,000 for this discharge.[89] 1983 was also the year in which Yorkshire Television produced a documentary "Windscale: The Nuclear Laundry", which claimed that the low levels of radioactivity that are associated with waste streams from nuclear plants such as Sellafield did pose a non-negligible risk.[90]

Due to algae forming in the pool and a buildup of radioactive sludge, it is impossible to determine exactly how much radioactive waste is stored in the FGMSP. British authorities have not been able to provide the Euratom inspectors with precise data and the European Commission has thus sued Great Britain in the European Court of Justice.[91][92] According to Greenpeace there is an expected 1300 kg of plutonium, 400 kg of which is in mud sediments.[93]

Radiation around the pool can get so high that a person is not allowed to stay more than 2 minutes, seriously affecting decommissioning.[94] The pool is not watertight; time and weather have created cracks in the concrete, letting contaminated water leak.[95]

Organ removal inquiry

In 2007 an inquiry was launched into the removal of tissue from a total of 65 dead nuclear workers, some of whom worked at Sellafield.[96] It has been alleged that the tissue was removed without seeking permission from the relatives of the late workers. Michael Redfern QC has been appointed to lead the investigation.[97] At the same time The Observer revealed that official documents showed that during the 1960s volunteer workers at Sellafield had participated in secret Cold War experiments to assess the biological effect of exposure to radioactive substances, such as from ingesting caesium-134.[98]

The inquiry final report was published in November 2010,[99] reporting that "...body parts had been removed between 1961 and 1992. The deaths of 76 workers – 64 from Sellafield and 12 from other UK nuclear plants – were examined, although the scope of the inquiry was later significantly widened."[100] The person behind this scheme was Dr Geoffrey Schofield, who became BNFL's Company chief medical officer, and who died in 1985. Sellafield staff did not breach any legal obligation, did not consider their actions untoward, and published the scientific information obtained in peer-reviewed scientific journals. It was the hospital pathologists, who were profoundly ignorant of the law, who breached the Human Tissue Act 1961 by giving Sellafield human organs, without any consents, under an informal arrangement.[99]

Health studies on Cumbria and Seascale

In 1983, the Medical Officer of West Cumbria, is said by Paul Foot to have announced that cancer fatality rates were lower around the nuclear plant than elsewhere in Great Britain.[101] In the early 1990s, concern was raised in the UK about apparent clusters of leukaemia near nuclear facilities.

A 1997 Ministry of Health report stated that children living close to Sellafield had twice as much plutonium in their teeth as children living more than 100 miles (160 km) away. Health Minister Melanie Johnson said the quantities were minute and "presented no risk to public health". This claim, according to a book written by Stephanie Cooke, was challenged by Professor Eric Wright, an expert on blood disorders at the University of Dundee, who said that even microscopic amounts of the man-made element might cause cancer.[102]

Studies carried out by the Committee on Medical Aspects of Radiation in the Environment (COMARE) in 2003 reported no evidence of raised childhood cancer in general around nuclear power plants, but did report an excess of leukaemia (cancer of the blood or bone) and non-Hodgkin's lymphoma (NHL) (blood cancer) near two other nuclear installations including Sellafield, the Atomic Weapons Establishment Burghfield and UKAEA Dounreay. COMARE's conclusion was that "the excesses around Sellafield and Dounreay are unlikely to be due to chance, although there is not at present a convincing explanation for them".[103] In earlier reports COMARE had suggested that " single factor could account for the excess of leukaemia and NHL but that a mechanism involving infection may be a significant factor affecting the risk of leukaemia and NHL in young people in Seascale."[104]

In a study published in the British Journal of Cancer, which also did not find an increase in any other cancers other than Leukemia, the authors of which attempted to quantify the effect population mixing might have on the Seascale leukaemia cluster. In the analysis of childhood leukaemia/NHL in Cumbria, excluding Seascale, they noted that if both parents were born outside the Cumbrian area (incomers), there was a significantly higher rate of leukaemia/NHL in their children. 1181 children were born in the village of Seascale between 1950 and 1989, in children aged 1–14 during this period, the Seascale cluster of 6 observed cases of NHL were noted. Two similarly aged children, born between 1950 and 1989, outside Seascale were also diagnosed with ALL/NHL before the end of 1992. The origin of birth of 11 of the 16 parents of these eight children was known, and found to be; 3 had parents born outside Cumbria and 3 had one parent born outside the UK. The studies authors strongly supported the hypothesis that the risk of ALL/NHL, in particular in the younger age group, increases with increased exposure to population mixing during gestation or early in life. Although they determined that the exact mechanism by which it causes these malignancies, apart from Kinlen's infection aetiology[105] that was mentioned, remained unknown, concluding that the possibility of additional risk factors in Seascale remains.[106]

In an examination of all causes of stillbirth and infant mortality in Cumbria taken as a whole, between 1950 and 1993, 4,325 stillbirths, 3,430 neonatal death and 1,569 lethal congenital anomalies, occurred among 287,993 births. Overall, results did not infer an increased risk of still birth or neonatal death in Cumbria, the rate of these negative outcomes were largely in line with the British baseline rate. However, there was a cautioned connection between a small excess of increased risk of death from lethal congenital anomalies and proximity to municipal waste incinerators and chemical waste crematoriums being noted. With two examples of the latter crematoriums operating in both Barrow-in-Furness and further afield at Carlisle, crematoriums which may have emitted various chemical dioxins during their operation.[107]

Irish objections

Potassium iodate tablets
An unopened box of potassium iodate tablets, distributed to every household in Ireland in the wake of 9/11 in case of a terror attack on reprocessing plants and nuclear power stations in Britain. Upon later expert Irish examination in 2007, this was found not to have been justified.[108][109] The Irish Department of Health advises that the tablets may now be disposed of with municipal waste.[109]

Sellafield has been a matter of consternation in Ireland, with the Irish Government and some of the population concerned at the risk that such a facility may pose to the country.

The Irish government has made formal complaints about the facility, and in 2006 came to an agreement with the British Government about the matter, as part of which the Radiological Protection Institute of Ireland and the Garda Síochána (the Irish police force) are now allowed access to the site.[110]

Manx objections

The Government of the Isle of Man has also registered protests due to the risk posed by radioactive contamination, due to the proximity of the Isle of Man. The Manx government has called for the site to be shut down.[111]

The Irish and Manx governments have collaborated on this issue, and brought it to the attention of the British-Irish Council.[112]

Norwegian objections

Similar objections to those held by the Irish government have been voiced by the Norwegian government since 1997.

Monitoring undertaken by the Norwegian Radiation Protection Authority has shown that the prevailing sea currents transport radioactive materials leaked into the sea at Sellafield along the entire coast of Norway and water samples have shown up to tenfold increases in such materials as technetium-99.[113] The Norwegian government is also seeking closure of the facility.[114]

Other controversies

MOX fuel quality data falsification

The MOX Demonstration Facility was a small-scale plant to produce commercial quality MOX fuel for light water reactors. The plant was commissioned between 1992 and 1994, and until 1999 produced fuel for use in Switzerland, Germany and Japan.

In 1999 it was discovered that the plant's staff had been falsifying quality assurance data since 1996.[115] A Nuclear Installations Inspectorate (NII) investigation concluded four of the five work-shifts were involved in the falsification, though only one worker admitted to falsifying data, and that "the level of control and supervision ... had been virtually non-existent.". The NII stated that the safety performance of the fuel was not affected as there was also a primary automated check on the fuel. Nevertheless, "in a plant with the proper safety culture, the events described in this report could not have happened" and there were systematic failures in management.[116]

BNFL had to pay compensation to the Japanese customer, Kansai Electric, and take back a flawed shipment of MOX fuel from Japan.[117] BNFL's Chief Executive John Taylor resigned,[118] after initially resisting resignation when the NII's damning report was published.[119][120]

Plutonium records discrepancy

On 17 February 2005, the UK Atomic Energy Authority reported that 29.6 kilograms (65 lb) of plutonium was unaccounted for in auditing records at the Sellafield nuclear fuel reprocessing plant. The operating company, the British Nuclear Group, described this as a discrepancy in paper records and not as indicating any physical loss of material. They pointed out that the error amounted to about 0.5%, whereas International Atomic Energy Agency regulations permit a discrepancy up to 1% as the amount of plutonium recovered from the reprocessing process never precisely matches the pre-process estimates.

The inventories in question were accepted as satisfactory by Euratom, the relevant regulatory agency.[121][122]


Sellafield's biggest decommissioning challenges relate to the leftovers of the early nuclear research and nuclear weapons programmes.[123] Sellafield houses "the most hazardous industrial building in western Europe" and the second-most hazardous, which hold a variety of leftovers from the first Magnox plants in ageing ponds.[123]

Some of the problems with The second most date back to the 1972 miners' strike: the reactors were pushed so hard that waste processing could not keep up, and "cladding and fuel were simply thrown into it’s cooling ponds and left to disintegrate."[123] Some of the problems date back to the original nuclear weapons programme at Sellafield, when Piles 1 and 2 were constructed at breakneck speed, and safe disposal was not a priority. One building still houses the aluminium cladding for the uranium fuel rods of Piles 1 and 2, and is modelled on a grain silo, with waste tipped in at the top and argon gas added to prevent fires.[123]

In 2019 KBR was awarded a contract to manage the de-commissioning of the Sellafield plant.

Sellafield in popular culture


Sting's 1985 song, "We Work the Black Seam", about the UK miners' strike (1984–85), included the line, "the poisoned streams in Cumberland", amongst other references suggesting that nuclear power had led to the collapse of the coal mining industry.

In 2010 Post-Punk group Spear of Destiny wrote the song "Windscale" on their album Omega Point which referenced the fire in 1957.

In 1992, rock bands U2, Public Enemy, Big Audio Dynamite II, and Kraftwerk held a "Stop Sellafield" concert for Greenpeace to protest against the nuclear factory. Stop Sellafield: The Concert was later released that year on VHS in the UK, and all proceeds went directly to Greenpeace.

Kraftwerk mentions Sellafield in the intro of the 1991 version of the song Radioactivity together with Chernobyl, Harrisburg and Hiroshima. On their 2005 live album Kraftwerk preface a live performance of Radioactivity with a vocoder voice announcing: Sellafield 2 will produce 7.5 tons of plutonium every year. 1.5 kilogram of plutonium make a nuclear bomb. Sellafield 2 will release the same amount of radioactivity into the environment as Chernobyl every 4.5 years. One of these radioactive substances, Krypton 85, will cause death and skin cancer.[124]

Déanta, a traditional Irish band from Northern Ireland, refers to Sellafield and its nuclear dangers in their song "Cold Grey Fairyland".

Runrig A Scottish folk-rock group, mention Sellafield in their 1993 song 'Move a Mountain'.


Fallout, a 2006 drama shown on the Irish national TV station RTÉ, based on the false premise[125] that parts of Ireland would need to be evacuated following a serious accident at Sellafield,[126] following the accident there are evacuation riots, societal collapse and widespread health impacts.[127]

Sellafield was the subject of Marilynne Robinson's 1989 book, Mother Country: Britain, the Welfare State, and Nuclear Pollution, a critique of British nuclear policy.

Sellafield is the central theme of Les Barker's comic poem 'Jason and the Arguments,' and is also mentioned in other Barker works.

The Irish attitude to Sellafield forms a key plot strand in Body Breaker, a crime thriller by Mike Craven

Norman Nicholson's poem Windscale, which refers to the 1957 accident, is a commentary on the poison that Nicholson believed nuclear power had introduced to an area of natural beauty.

A595 road

The A595 is a primary route in Cumbria, in Northern England that starts in Carlisle, passes through Whitehaven and goes close to Workington, Cockermouth and Wigton. It passes Sellafield and Ravenglass before ending at the Dalton-in-Furness by-pass, in southern Cumbria, where it joins the A590 trunk road. The road is mostly single carriageway, apart from in central Carlisle, where it passes the castle as a busy dual carriageway road named Castle Way, and prior to that as Bridge Street and Church Street, where it passes close to the McVitie's or Carr's biscuit factory. The Lillyhall bypass is also dual carriageway.

The road in the Whitehaven area was laid out in the 1930s and the A595 was designated a trunk route in 1946. It was detrunked in 1998, apart from an 18-mile (29 km) section between Little Clifton and Calder Bridge. This section represents the route from Sellafield to the A66.

At Dove Ford in Grizebeck the road passes through a farmyard.

Beckermet railway station

Tracks were laid southwards from Whitehaven and Moor Row as far as Egremont by the Whitehaven, Cleator and Egremont Railway, opening to passengers on 1 July 1857.

By the 1860s the company sought to extend southwards from Egremont to meet the coastal line at Sellafield, aiming for Millom, Barrow-in-Furness and beyond. The Furness opposed this, but the two companies came to an accommodation and built the Egremont to Sellafield extension as a joint line. Beckermet railway station was the sole intermediate passenger station on the extension.

The station was on the western edge of the village, in Cumbria, England.

British Nuclear Fuels Ltd

British Nuclear Fuels Limited (BNFL) was a nuclear energy and fuels company owned by the UK Government. It was a former manufacturer and transporter 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.

Until 2003, its headquarters were at Risley, near Warrington, England. BNFL's headquarters were then moved to Daresbury Park industrial estate, also near Warrington.

On 1 April 2005, BNFL formed a new holding company and started a rigorous restructuring process which would transfer or sell most of its entire domain, divisions. In 2005, it transferred all of its nuclear sites to the Nuclear Decommissioning Authority. It then sold its Westinghouse Electric Company subsidiary in February 2006. Later, BNFL sold the separate companies that made up its major subsidiary, British Nuclear Group, leaving a decommissioning and reprocessing organisation which became Sellafield Ltd. By May 2009, BNFL had completed the sales of all its assets and had no remaining operational activities or businesses.

BNFL continued to exist only as a legal entity to meet all pension liabilities and any obligations arising from disposal programmes. However, on 14 October 2010, the Minister for the Cabinet Office, Francis Maude, announced that BNFL would be abolished along with a number of other government organisations.

Cold Fell (Calder Bridge)

Cold Fell is a hill in the west of the English Lake District. It is easily climbed from the road between Ennerdale Bridge and Calder Bridge. This road is in fact known as Cold Fell Road and is used by many Sellafield employees living in Cockermouth.

The fell is grassy and nowhere steep. The summit is very flat but offers a view of the west Cumbrian coastline and Sellafield. Cold Fell is home to a group of horses which roam freely about a number of fells in the area.

Cold Fell is the subject of a chapter of Wainwright's book The Outlying Fells of Lakeland. Unusually he does not specify a route of ascent, saying: "If, with the aid of the map only, you cannot find the top of Cold Fell, then take some good advice, old man, and pack it in." He lists the height as 955 feet (291 m).

Cumbrians Opposed to a Radioactive Environment

Cumbrians Opposed to a Radioactive Environment (CORE) is a non-political, non-profit organisation, located in Barrow-in-Furness, which since 1980 has campaigned against all aspects of the operation of Sellafield, formally Windscale and the site of the 1957 reactor fire. Issues of current interest are radioactive air and sea discharges, resultant environmental contamination, and the health detriment to local communities and wildlife. As well as preparing compensation cases for Sellafield workers, CORE has taken part in many direct action campaigns which have resulted in a string of injunctions.

Egremont, Cumbria

Egremont is a market town, civil parish and two electoral wards (North and South) in the Borough of Copeland in Cumbria, England, 5 miles (8.0 km) south of Whitehaven and on the River Ehen. Historically in Cumberland, the town, which lies at the foot of Uldale Valley and Dent Fell, has a long industrial heritage including dyeing, weaving and iron ore mining. It had a population of 7,444 in 2001, increasing to 8,194 at the 2011 Census.The town's layout today is much the same as at the time of Richard de Lucy around 1200 with its wide Main Street opening out into the market place. The remains of the Norman castle, built in the 12th century, are situated at the southern end of Main Street near the market place.

Egremont was granted a charter for a market and annual fair by King Henry III in 1266. The resulting annual Crab Fair now hosts the World Gurning Championships.The modern economy is built on services, media and tourism, together with nuclear industry at Sellafield.

Egremont railway station

Egremont railway station was built by the Whitehaven, Cleator and Egremont Railway as the first southern terminus of what would become the Moor Row to Sellafield branch. In 1878 the company was bought out by the LNWR and Furness Railway who operated the line jointly until grouping in 1923.

The station was towards the northern end of the town, in Cumbria, England.

Fallout (TV series)

Fallout is a RTÉ two-part fictional, doom laden, docudrama. It deals with the nuclear fallout following a hypothetical disaster in the Sellafield Nuclear Reprocessing Plant in Cumbria on the British coast of the Irish Sea. The docu-drama suggests that, due to a changing wind direction, Ireland would bear the brunt of the British accident. The docu-drama was based on the false premise, that such an accident as depicted in the drama could happen and that parts of Ireland would need to be evacuated following a serious accident at Sellafield. Dr Ann McGarry, chief executive of the Radiological Protection Institute of Ireland, said: "The scenario envisaged in the programme is not realistic and grossly exaggerates the amount of radioactivity that could reach Ireland. The RPII cannot envisage any realistic scenario that would cause the radiation levels in Ireland to reach the concentrations as what was depicted in the drama" Following the dramatized accident, the docu-drama depicts Irish evacuation riots, societal collapse and widespread health impacts.

Jean McSorley

Jean McSorley is long-standing anti-nuclear campaigner, who formed the group "Cumbrians Against a Radioactive Environment" (Core) from her home town of Barrow-in-Furness, England in protest at the local Sellafield plant. As well as fighting compensation cases for Sellafield workers, Core took part in direct action campaigns. It has been incorrectly reported that they earned a string of injunctions.[1] Neither CORE as a group, nor the individuals involved, have received injunctions; but Greenpeace – who Jean McSorley subsequently worked for - has been served with a number due to its actions against nuclear operations.

Ms McSorley worked as the anti-nuclear coordinator for Greenpeace throughout the 1990s and travelled to Australia and the Far East. She was the senior anti-nuclear campaigner for Greenpeace in the 2000s, and became the victim of an espionage scandal when nuclear power giant EDF committed industrial espionage against Greenpeace. In November 2011, EDF was fined £1.3m and ordered to pay £428,000 in damages to Greenpeace after being found guilty of spying on the environmental group. EDF executive Pierre-Paul François was sentenced to three years’ imprisonment. His deputy, Pascal Durieux, was sentenced to three years’ imprisonment, with two of them suspended.McSorley has contributed to several academic works on nuclear energy and wrote her own book, Living in the Shadow, in 1990. As of 2011, she still acts as a consultant to Greenpeace.Jean McSorley lived in Australia from 1990 until 2003, whilst there she was first head of Greenpeace Australia's nuclear campaign before moving to become the Campaign Coordinator for the Nuclear & Energy Campaign in Asia for Greenpeace International.She has also worked as a policy analyst for The Cabinet Office of New South Wales (Health and Aboriginal Affairs).She was a member of the Australian Federal Nuclear Committee 2000-2003. Since 2011 she has worked as an independent consultant to Greenpeace and other NGOs.

Magnox Ltd

Magnox Ltd is a nuclear decommissioning Site Licence Company (SLC) controlled by Cavendish Fluor Partnership, its designated Parent Body Organisation (PBO). It operates under contract for the Nuclear Decommissioning Authority (NDA), a government body set up specifically to deal with the nuclear legacy under the Energy Act 2004.

Magnox Ltd is responsible for the decommissioning of ten Magnox nuclear power stations in the United Kingdom. The ten sites are Berkeley, Bradwell, Chapelcross, Dungeness A, Hinkley Point A, Hunterston A, Oldbury, Sizewell A, Trawsfynydd and Wylfa. All the sites have ceased production. In addition, as part of the Trawsfynydd unit, Magnox Ltd operates a hydro-electric power station at Maentwrog.

The only Magnox power station in the UK not managed by Magnox Ltd is Calder Hall, which is part of the Sellafield site and is controlled by another SLC, Sellafield Ltd.

In September 2019 Magnox Ltd will become a subsidiary of the NDA.

Moor Row railway station

Moor Row railway station was built by the Whitehaven, Cleator and Egremont Railway. It served the village of Moor Row, Cumbria, England.

National Nuclear Laboratory

The National Nuclear Laboratory (informally NNL, formerly Nexia Solutions) is a UK government owned and operated nuclear services technology provider covering the whole of the nuclear fuel cycle. It is fully customer-funded and operates at six locations in the United Kingdom. Its customers have included the Nuclear Decommissioning Authority, Sellafield Ltd, Westinghouse, the Health and Safety Executive, the Ministry of Defence, the UK Atomic Energy Authority, VT Nuclear and British Energy. It also has extensive links with academia, including collaborative agreements on waste immobilisation and disposal with the University of Sheffield and on nuclear materials research with the University of Manchester.


NuGeneration (NuGen) is a company in liquidation that planned to build a new nuclear power station nearby the Sellafield nuclear site in the United Kingdom. The proposed site was called Moorside, and is to the north and west of Sellafield. On 8 November 2018, Toshiba announced their withdrawal from the project and intent to liquidate NuGen.

Nuclear Decommissioning Authority

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.

Although the NDA itself employs only 300 staff, its annual budget is £3.2 billion. The vast majority of the NDA budget is spent through contracts with Site Licence Companies, who also sub contract to other companies which provide special services. The NDA aims to do this by introducing innovation and contractor expertise through a series of competitions similar to the model that has been used in the United States.

In April 2017, the NDA lost a legal case in the Supreme Court regarding the procurement of a sizeable contract for the decommissioning of 12 different Magnox nuclear facilities when EnergySolutions EU Ltd. (now called ATK Energy EU Ltd.) challenged a decision in connection with ATK’s unsuccessful bid. In February 2018 the UK parliament's Public Accounts Committee (PAC) concluded that the NDA had "dramatically under-estimated" costs and "completely failed" in the procurement and management of the Magnox Ltd contract, which was one of the highest value contracts let by the government. An independent inquiry into the deal was set up.


The Radball is a 140 mm (5½") diameter deployable, passive, non electrical gamma hot-spot imaging device that offers a 360 degree view of the deployment area. The device is particularly useful in instances where the radiation fields inside a nuclear facility are unknown but required in order to plan a suitable nuclear decommissioning strategy. The device has been developed by the UK's National Nuclear Laboratory and consists of an inner spherical core made of a radiation sensitive material and an outer tungsten based collimation sheath. The device does not require any electrical supply or communication link and can be deployed remotely thus eliminating the need for radiation exposure to personnel. In addition to this, the device has a very wide target dose range of between 2 and 5,000 rads (20 mGy to 50 Gy) which makes the technology widely applicable to nuclear decommissioning applications.

Sellafield Ltd

Sellafield Ltd is a nuclear decommissioning Site Licence Company (SLC) controlled by the Nuclear Decommissioning Authority (NDA), a government body set up specifically to deal with the nuclear legacy under the Energy Act 2004. Until 2016, it was operated under licence from the NDA by a third party Parent Body Organisation called Nuclear Management Partners.

Sellafield Ltd's main aim is to manage the decommissioning of the Sellafield facility in Cumbria, England, on behalf of the NDA. The company employs more than 13,000 workers and its focus is to deliver accelerated nuclear decommissioning and clean-up programmes. It is also involved in world-leading power operations, nuclear fuel production and reprocessing, international decommissioning, and international transportation.

Sellafield railway station

Sellafield railway station serves the nuclear facility of Sellafield in Cumbria, England. It is operated by Northern which provide all passenger services. The station is a stop on the scenic Cumbrian Coast Line, 11 1⁄2 miles (18.5 km) south of Whitehaven. Some through trains to the Furness Line towards Lancaster stop there.

The station, which dates from 1850, is a busy freight location, because much of the nuclear waste for Sellafield's Thorp nuclear fuel reprocessing plant is carried there by train from the docks in Barrow-in-Furness, or from rail-connected nuclear power stations elsewhere in the UK. The facility also generates significant commuter traffic for the railway, with workers travelling by train from nearby towns & villages.The station is at the end of the single-line section from Whitehaven, which is operated using the electric key token system. From there, the line south towards Ravenglass and Barrow is double track, except for the final section between Park South Junction (south of Askam) and Barrow, which was reduced to a single track in the late 1980s.

The station configuration is unusual in that the southbound ('up' line) is bi-directional through the station and has platform faces on both sides. However, only the eastern platform face is used, the other side being fenced off. This allows trains from the south to terminate and turn back without having to enter the single-line section to St Bees. The signal box controlling the layout is located at the north end of the station, whilst the exchange sidings for the plant, and the loco depot used by DRS freight trains, are to the south. There are two water cranes at the station, one at each end.The station used to be the southern terminus of the former Whitehaven, Cleator and Egremont Railway line from Egremont, from August 1869 until the line's closure in March 1964.

Thermal Oxide Reprocessing Plant

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 (which is the site licensee company). Spent nuclear fuel from nuclear reactors is reprocessed to separate the 96% uranium and the 1% plutonium, which can be reused in mixed oxide fuel, from the 3% radioactive wastes, which are treated and stored at the plant. The uranium is then made available for customers to be manufactured into new fuel.

On 14 November 2018 it was announced that operations had ended at THORP. The facility will be used to store spent nuclear fuel until the 2070s.

Woodend railway station

Woodend railway station (formally known as "Woodend for Cleator and Bigrigg") was planned by the Whitehaven, Cleator and Egremont Railway on its Sellafield to Moor Row branch, but by the time the station opened the company had been bought out by the LNWR and Furness Railway who operated the line jointly until grouping in 1923.

The station was in the hamlet of Wood End and served the villages in its full name, in Cumbria, England.
