Sellafield is a nuclear reprocessing 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 is an off-shoot from the original nuclear reactor site at Windscale which is currently undergoing decommissioning and dismantling. Calder Hall, another neighbour of Windscale is also undergoing decommissioning and dismantling of its 4 nuclear power generating reactors.
Ownership and facilities
Sellafield was previously owned and operated by British Nuclear Fuels plc (BNFL), but is now operated by Sellafield Ltd and, since 1 April 2005, has been owned by the Nuclear Decommissioning Authority.
In 2008 the Nuclear Decommissioning Authority contracted the management of Sellafield Ltd to Nuclear Management Partners, a consortium of US company URS, British company AMEC, and AREVA of France. The initial contract is for five years, with extension options to 17 years.
Facilities at the site include the THORP nuclear fuel reprocessing plant and the Magnox nuclear fuel reprocessing plant. It is also the site of the remains of Calder Hall, the world's first commercial nuclear power station, now being decommissioned, as well as some other older nuclear facilities at Windscale.
In 1981 the name of the site was changed back from Windscale to Sellafield, possibly in an attempt by the United Kingdom Atomic Energy Authority to disassociate the site from recent press reports about its safety.
The Sellafield site was originally occupied by ROF Sellafield, a Second World War Royal Ordnance Factory, which, with its sister factory, ROF Drigg, at Drigg, produced TNT.[nb 1] After the war, the Ministry of Supply adapted the site to produce materials for nuclear weapons, principally plutonium, and construction of the nuclear facilities commenced in 1947. The site was renamed Windscale to avoid confusion with the Springfields uranium processing factory near Preston. The two air-cooled, graphite-moderated Windscale reactors 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 was also the site of the prototype British Advanced gas-cooled reactor.
With the creation of the United Kingdom Atomic Energy Authority (UKAEA) in 1954, ownership of Windscale Works passed to the Authority. The first of four Magnox reactors became operational in 1956 at Calder Hall, adjacent to Windscale, and the site became Windscale and Calder Works. Following the breakup 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. The remainder of the site remained in the hands of the UKAEA and is still called Windscale.
Since its inception as a nuclear facility Sellafield has also been host to a number of reprocessing operations, which separate the uranium, plutonium, and fission products from spent nuclear fuel. 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 18 October 2010 the British government announced that Sellafield was one of the eight sites it considered suitable for future nuclear power stations. On 23 June 2011, the British government confirmed plans to build a new nuclear reactor at Sellafield, to be completed before 2025.
The Windscale Piles
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, with the initial fuel loading into the Windscale Piles commencing in July 1950. By July 1952 the separation plant was being used to separate plutonium and uranium from spent 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 2000 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.
The Windscale fire
The Windscale Piles were shut down following a fire in Pile 1 on 10 October 1957 which destroyed the core and released an estimated 750 terabecquerels (20,000 curies) of radioactive material into the surrounding environment, including Iodine-131, which is taken up in the human body by the thyroid. 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, by which time UK had enough plutonium for some atomic bombs and work was progressing well at the Fast Breeder Reactor at Dounreay.
In the 1990s, the United Kingdom Atomic Energy Authority started to implement plans to decommission, disassemble and clean up both piles; the decommissioning is now partially complete. 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.
The 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. Following the commissioning of the 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.
Calder Hall nuclear power station
Calder Hall was the world's first nuclear power station to deliver electricity in commercial quantities (although the 5 MWe "semi-experimental" reactor at Obninsk in the Soviet Union was connected to the public supply in 1954). The 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. Calder Hall had four Magnox reactors capable of generating 60 MWe (net) of power each, reduced to 50 MWe in 1973. The reactors were supplied by the UKAEA and the turbines by C.A. Parsons & Company. The civil engineering contractor was Taylor Woodrow Construction. First connection to the grid was on 27 August 1956, and the plant was officially opened by Queen Elizabeth II on 17 October 1956. When the station closed on 31 March 2003, the first reactor had been in use for nearly 47 years.
In its early life, it was primarily used to produce weapons-grade plutonium, with two fuel loads per year, and electricity production as a secondary purpose. 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 of Calder Hall
Calder Hall had four cooling towers, built in 1950-1956 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 47 years, creating a landmark visible from the village of Seascale. Conflict arose over renovating Calder Hall and preserving the towers, but costs effectively defeated all attempts to do so.
The four cooling towers were demolished by controlled implosions on Saturday 29 September 2007, by Controlled Demolition Inc. A period of 12 weeks was required to remove asbestos in the towers' rubble.
Windscale Advanced Gas Cooled Reactor (WAGR)
The Windscale Advanced Gas Cooled Reactor (WAGR) 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 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. This reactor was shut down in 1981, and is now part of a pilot project to demonstrate techniques for safely decommissioning a nuclear reactor.
Magnox reprocessing plant
In 1964 the Magnox reprocessing plant came on stream to reprocess spent nuclear fuel from the Magnox reactors. The plant uses the "plutonium uranium extraction" Purex method for reprocessing spent fuel, with tributyl phosphate as an extraction agent. The Purex process produces uranium, plutonium and fission products as output streams. Over the 30 years from 1971 to 2001 B205 has reprocessed over 35,000 tonnes of Magnox fuel, with 15,000 tonnes of fuel being regenerated. Magnox fuel is reprocessed since it corrodes if stored underwater, and routes for dry storage have not yet been proven.
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.
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, however, did not discover the leak until safeguards staff reported the discrepancies. Some 19 tonnes of uranium and 160 kilograms of plutonium dissolved in nitric acid has been pumped from the sump vessel into a holding tank.
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.
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 Windscale Vitrification Plant.
The vitrification plant
In 1991 the Windscale 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.
The 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. 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. In 2008 orders for the plant had to be fulfilled at COGEMA in France, and the plant was reported in the media as "failed" with a total build and operation cost of £1.2 billion.
On 12 May 2010 an agreement was reached with existing Japanese customers on future MOX supplies. In July 2010 Areva was contracted to design and supply a new rod line to improve reliability and production rate.
Enhanced Actinide Removal Plant
In its early days, Sellafield 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 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 has recently (2004) been enhanced to further reduce the quantities of Technetium-99 released to the environment.
Radioactive waste stores
Sellafield has a number of radioactive waste stores, mostly on an interim basis while a national waste repository plan is developed and implemented. The stores include:
- 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
- Engineered drum stores - Site stores for plutonium contaminated material
- Encapsulated product stores - Site stores for grouted wastes
- Vitrified product store - Vitrified high level waste
Fellside Power Station
Fellside Power Station is a 168MWe 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 managed by PX Ltd and Doosan Babcock. 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. BNFL bought SSE's 50% share in January 2002.
Sellafield and the local community
Sellafield directly employs around 10,000 people and is one of the two largest, non-governmental, employers in West Cumbria (along with BAE Systems at Barrow-in-Furness), with approximately 90% of the employees coming from West Cumbria. 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.
Sellafield Centre - Business and Information Centre
Formerly the Sellafield Visitors' Centre, 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. It is still open to the public but only at selected times.
At its peak, the Visitors' Centre attracted an average of 1,000 people per day. In recent years, its popularity has deteriorated, prompting the change from tourist attraction to conference facility.
Environment and health issues
The site has been the subject of much controversy because of discharges of radioactive material, mainly accidental but some alleged to have been deliberate. Since the early 1970s and the rise of the environmental movement in the US and Europe, there has also been general scepticism of the nuclear industry. In part this has not been helped by the industry's early connections to the nuclear weapons programme.
Between 1950 and 2000 there have been 21 serious incidents or accidents involving some off-site radiological releases that merited 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. 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 discharged by pipeline into the Irish Sea. Some claim that the Irish Sea remains one of the most heavily contaminated seas in the world because of these discharges. 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. Cattle and fish in the area are 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. 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 6.78 gigabecquerels of technetium-99 each year despite not having a nuclear industry). 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, 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 processing plant and probably less than the dose from naturally occurring background levels of 210Po." Because of the need to comply with the OSPAR Convention, British Nuclear Group (the licensing company for Sellafield) have recently commissioned a new process in which technetium-99 is removed from the waste stream and vitrified in glass blocks.
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. However, contracts signed 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.
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 stretch of coast between St. Bees and Eskmeals, along with warnings against swimming in the sea. BNFL received a fine of £10,000 for this discharge. 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.
The open pit in building B30, named dirty thirty, is used to store radioactive leftovers from the Magnox period and renowned for its bad state. The pool is 20m wide, 150m long and 6m deep. Birds land on its surface and take small amounts of radioactive substances with them. The pool was used from 1960 until 1986. A confinement wall is scheduled to be built in the future to help it withstand earthquakes. The pool is to be emptied and dismantled in years to come.
It is impossible to determine exactly how much radioactive waste is stored in B30; algae is forming in the pool, making visual examinations difficult. British authorities have not been able to provide the Euratom inspectors with precise data. The European Commission has thus sued Great Britain in the European Court of Justice. There are expected to be about 1.3 tons of plutonium, 400 kg of which are in mud sediments. It is thought the pool also contains waste from the Tokai Mura plant (Japan).
Radiation around the pool can get so high that a person is not allowed to stay more than 2 minutes, seriously affecting decommissioning. The pool is not watertight, time and weather have created cracks in the concrete, letting contaminated water leak.
Organ removal inquiry
In 2007 an inquiry was launched into the removal of tissue from a total of 65 deceased nuclear workers, some of whom worked at Sellafield. 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. 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.
The inquiry final report was published in November 2010, 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." 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.
According to Stephanie Cooke, the British Government has been "at pains over the years to play down attempts to correlate cancers with Sellafield radioactivity, particularly when it involves individuals living near the plant but not working at it".
In 1983, the Medical Officer of West Cumbria announced that cancer fatality rates were actually lower around the nuclear plant than elsewhere in Great Britain. 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". The University of Dundee's Professor Eric Wright, a leading expert on blood disorders, challenged this claim, saying that even microscopic amounts of the man-made element might cause cancer.
Detailed 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 nuclear plants including Sellafield, AWE Burghfield and UKAEA Dounreay. COMARE's opinion is 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". In earlier reports COMARE had suggested that "..no 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."
Sellafield has been a matter of some consternation in Ireland, with the Irish Government and some members 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 recently came to a friendly agreement with the British Government about the matter, as part of which the Radiological Protection Institute of Ireland and An Garda Síochána (Irish Police Force) are now allowed access to the site. However, Irish government policy remains that of seeking the closure of the facility.
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 ten-fold increases in such materials as Technetium-99. Fears for the reputation of Norwegian fish as a safe food product have been a concern of the country's fishing industry, though the radiation levels have not been conclusively proved as dangerous for the fish. The Norwegian government is also seeking closure of the facility.
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 some quality assurance data since 1996. 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.
BNFL had to pay compensation to the Japanese customer, Kansai Electric, and take back a flawed shipment of MOX fuel from Japan. BNFL's Chief Executive John Taylor resigned, after initially resisting resignation when the NII's damning report was published.
Plutonium records discrepancy
On 17 February 2005, the UK Atomic Energy Authority reported that 29.6 kg (65.3 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.
In 2003 it was announced that the Thorp reprocessing plant would be closed in 2010. Originally predicted to make profits for BNFL of £500m, by 2003 it had made losses of over £1bn. 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.
In November 2008 Sellafield was taken over by a new US-led consortium (US company URS Corp., French firm 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.
Sellafield's biggest decommissioning challenges relate to the leftovers of the early nuclear research and nuclear weapons programmes. Sellafield houses "the most hazardous industrial building in western Europe" (building B30) and the second-most (building B38), which hold a variety of leftovers from the first Magnox plants in ageing ponds. Some of the problems with B38 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 B38's cooling ponds and left to disintegrate." 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. Building B41 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.
In 2009 Sellafield decommissioning accounts for 40% of the budget of the Nuclear Decommissioning Authority - over £1.1bn. Sellafield decommissioning and waste disposal is expected to cost the taxpayer £1.5bn per year for many years.
Sellafield in popular culture
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.
U2's performance from the "Stop Sellafield" concert was held during their Zoo TV Tour on 19 June 1992 at the G-Mex Centre in Manchester, England. Two tracks from the concert, "The Fly" and "Even Better Than the Real Thing", were later released on the band's "City of Blinding Lights" CD single and on the Zoo TV: Live from Sydney DVD.
Since 1992, German band Kraftwerk has introduced their song "Radioactivity" in their live shows with a video clip criticizing the Sellafield-2 reactor for radiation released into the atmosphere during typical operation and the dangers of reprocessing plutonium in regard to nuclear proliferation:
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.
This introduction can be heard on their 2005 live album and DVD Minimum-Maximum. Sellafield-2 was the name given by environmental groups including Greenpeace to a proposed second plant to reprocess oxide fuel (it is not obvious how seriously proposed, a public enquiry was never opened).
The Irish folk musician, Derek Warfield, wrote a song critical of Sellafield, "Sellafield Tiocfaidh Ar La", which was included in his 2001 album, Slan Abahile.
Fallout, a programme shown in 2006 on the Irish national TV station RTÉ, was a documentary-style drama showing the possible effects of a serious accident at Sellafield. The programme highlighted the fact that an accident could cause long scale contamination of Ireland's most densely populated areas, including its capital city, Dublin.
Sellafield was the subject of Marilynne Robinson's 1989 book, Mother Country, a critique of British nuclear policy.
