Considerations
- When fossil fuel costs fell in the 1980's, demand for nuclear energy wained with the fears of radiation and nuclear proliferation by rogue countries. Nuclear weapons became larger and deadlier in the throws of the Cold War, ultimately enough nuclear weapons were present to destroy the planet many times over. Other countries began to develop nuclear power for use and the IAEA began to monitor those countries to prevent the creation of weapons grade plutonium. Nuclear reactors had been being installed in submarines and naval ships in NATO and the Soviet Union for years, creating whole fleets running on nuclear energy.
Features
- The largest push back against nuclear power came after two events rattled public awareness of the dangers potentially posed by this form of power. In 1979, the nuclear reactor at Three Mile Island had a partial core meltdown which resulted in the release of a substantial amount of radioactive krypton. The lack of information by government sources during the initial panic, led many to question the future of nuclear energy.
The most disastrous event in took place at the Chernobyl nuclear power plant in 1986 in the Soviet Union. Reactor number four exploded at 1:23 AM, releasing a plume of radioactive fallout larger than that left in the wake of the Hiroshima bombing. Initially, only two people died, but over a half million civilians were exposed to the radioactive fallout, making exact figures impossible to determine. The IAEA attributes fifty-six people directly killed by the blast with a possible additional 4,000 individuals with cancer.
Misconceptions
- After the effects of Three Mile Island and Chernobyl, the worldwide community questioned the safety of nuclear energy. Beyond the obvious worries of accidents, the questions about what to do with spent plutonium has yet to be determined. 95% of spent fuel can be reprocessed with modern technologies, however, the remaining 5% creates a burden of storage, as the spent fuel is deadly for thousands of years. Attempts to create a storage facility on Yucca Mountain have stalled and deals are trying to be made to store large amounts of spent fuel in Siberia with Russian assistance.
Timeline: Nuclear power in the United Kingdom
Key events in the history of nuclear power in Britain1956 The Queen opens the first two 65MW dual purpose reactors at Calder Hall at Windscale (later Sellafield). The government says Britain has become "the first station anywhere in the world to produce electricity from atomic energy on a full industrial scale".1957 The government promises a nuclear power building programme that would achieve 5,000-6,000MW capacity by 1965.The world's first nuclear power accident occurs at Windscale in west Cumbria, when a fire in the reactor results in a release of radioactivity. The then prime minister, Harold Macmillan, told the cabinet that he was suppressing the report that detailed the full extent of the disaster, defects in organisation and technical shortcomings. The facts were not made public for 30 years.1960 Government white paper scales back nuclear building plans to 3,000MW, acknowledging that coal generation is 25% cheaper.1962 Berkeley nuclear power station, situated on the bank of the River Severn, in Gloucestershire, begins generating electricity.1964 The Government white paper, The Second Nuclear Programme, says 5,000MW of new plants will be built between 1970-76.This begins the era of advanced gas-cooled reactors (AGR) after other designs are rejected. Minister for power Fred Lee tells the House of Commons: "We have won the jackpot this time - we have the greatest breakthrough of all times."Magnox reprocessing plant opens at Windscale for the dual purpose of producing plutonium for nuclear weapons and fast-breeder reactor fuel.1965 Proposed building programme for AGRs increased to 8,000MW.1966 First AGR construction begins.1977 Last of seven AGR stations is ordered for Heysham, Lancashire, to complete the 8,000MW programme. The Central Electricity Generating Board describes them as "one of the major blunders of British industrial policy."1979 Energy secretary David Howell announces 10 new pressurised water reactors (PWR) to be built, calling nuclear power "a cheaper form of electricity generation than any known to man".1983 Planning inquiry for the first PWR at Sizewell in Suffolk starts, lasting two years.Government forced to abandon dumping of low and intermediate-level nuclear waste in the Atlantic following pressure from environmental groups.1986 The world's worst nuclear accident occurs at Chernobyl in Ukraine, then part of the Soviet Union.1987 Plans for Sizewell B approved.1988 Construction begins on Sizewell B, the first of a family of four PWRs that are planned but later abandoned.The government decides to privatise electricity production and a "nuclear tax" is proposed.1989 Magnox reactors are withdrawn from electricity privatisation. The city refuses to buy the older stations because of decommissioning costs and the taxpayer is left with the bill.AGRs and Sizewell B are withdrawn from privatisation because city investors discover that the cost of generating nuclear power is far greater than that of coal.1990 Nuclear levy is introduced to cover the difference between the cost of generating nuclear energy and coal, adding 11% to electricity bills.The cost of building Sizewell B increases from £1.69bn to £2.03bn.1991 Government announces plans for a nuclear waste repository costing between £2.5bn and £3.5bn that would be completed by 2005.1992 International Atomic Agency says the building up of vast stocks of plutonium at reprocessing plants poses "a major political and security risk".1993 It is revealed that the 11% nuclear levy on electricity bills has not been put aside for dealing with decommissioning costs and waste, but spent on building Sizewell B. Economists estimate that the projected income from the levy between 1990-98 will represent a £9.1bn subsidy for the nuclear industry.1994 Government announces nuclear reviews, one into whether new nuclear stations can be built and the seond into whether the industry can be privatised.1995 Government decides to make a second attempt to privatise AGRs and the still-to-be-completed Sizewell B.1996 Sell-off of the newer nuclear stations goes ahead. Despite calls for its cancellation because of delays and cost overruns, Sizewell B opens.1997 Two nuclear waste stores are to be built at Sellafield, to take intermediate-level waste for the next 50 years. Another 10 are planned for the future.1998 Deputy prime minister John Prescott signs agreement to progressively reduce concentrations of radioactive substances in the marine environment as a result of emissions from Sellafield.2000 In February, the British Nuclear Fuels chief executive, John Taylor, resigns over a scandal relating to faked safety records at the Sellafield plant in Cumbria.2002 Bradwell power station is shut down after 40 years of operation.2003 The government's 2003 energy white paper highlights the lack of planned new nuclear plants to replace decommissioned ones, but rejects the technology, saying "its current economics make it an unattractive option for new, carbon-free generating capacity".September 2004 The European commission launches legal action against the government over "unacceptable" failings in dealing with nuclear waste at Sellafield.May 2005 A leak of highly radioactive nuclear fuel forces the closure of Sellafield's Thorp reprocessing plant.October 2005 The government's chief scientific adviser, Sir David King, voices his support for a nuclear power revival, saying there are economic as well as environmental reasons for a new generation of reactors.November 2005 The then prime minister, Tony Blair, commissions a second white paper on energy policy and confirms that a new generation of nuclear power station's is to be considered. He says nuclear power is once again a serious option because "the facts have changed over the last couple of years".March 2006 The Sustainable Development Commission warns Tony Blair that there is "no justification" for a new nuclear programme.April 2006 The government's environment audit committee warns that a new generation of nuclear power stations would not be able to avert a serious energy crisis. The government has become "too focused" on nuclear energy, it says.May 2006 Tony Blair endorses a new generation of nuclear power stations in a speech to business leaders. He says the issue of a new generation of stations is back on the agenda "with avengeance". He is backed up again by King.July 2006 The new white paper confirms that nuclear power is back on the agenda. It says a mix of energy supplies is essential and that new nuclear power stations could make a significant contribution. The review says it will be up to the private sector to cover the costs of investment, decommissioning and storage of nuclear waste.Major power generators such as E.ON and EDF welcome what they call an "important milestone".October 2006 Greenpeace launched a court action claiming that the government's consultation was "legally flawed".February 2007 Greenpeace wins its case and governmen launches a new consultation, which includes plans to treble the amount of electricity from renewable sources and signals a return to the government's nuclear agenda.A Guardian/ICM poll shows opponents of nuclear energy narrowly outnumber supporters, by 49% to 44%.November 2007 New prime minister, Gordon Brown, calls for an acceleration of nuclear power in a speech to business leaders.January 2008 The government announces its nuclear plans.

An 11th site at Dungeness was turned down because of the "adverse effect" it could have on the local ecosystem.December 2009 The operator of Sellafield, Britain's biggest nuclear complex, is fined £75,000 following safety lapses which led to the radioactive contamination of staff in July 2007.March 2010 The government announces a £170m funding package for the British nuclear manufacturer Sheffield Forgemasters, who will build a 15,000-tonne press to make large forgings used in modern reactors.May 2010 The Liberal Democrats abandon opposition to the development of new nuclear plants, with new energy secretary Chris Huhne saying a construction programme would be acceptable "without new public subsidy".The Health and Safety Executive is cracking down on Sellafield's operators, Nuclear Management Partners, after a series of radioactive leaks and safety blunders.June 2010 Huhne reveals Britain is facing a £4bn black hole in unavoidable nuclear decommissioning and waste costs.The government cancels a proposed loan of £80m to Sheffield Forgemasters approved by the previous government.August 2010 The Health and Safety Executive says the schedule for the UK's nuclear reactor building programme has slipped behind, as the two proposed designs await approval.A report prepared for the government by the British Geological Surveyidentifies the Lake District as the area of Cumbria most geologically suitable for nuclear waste disposal.January 2011 Huhne announces plans to raise the amount nuclear operators will have to pay towards the cost of any accident in the UK to £1bn.March 2011 In an Observer interview, Huhne says Britain may back away from the use of nuclear energy because of safety fears and a potential rise in costs after the Fukushima disaster.Sir David King, the former government chief scientist, says the UK's nuclear industry is in no shape to cope with a large-scale reactor building programme and must be overhauled if the coalition wants to push ahead with its nuclear expansion plans.April 2011 Government plans to build a new programme of nuclear power stations in England will be delayed by at least three monthswhile a report into what the UK can learn from Fukushima is published.May 2011 The UK government's advisory committee COMARE clears nuclear power plants of causing childhood cancers.A report by the energy and climate change select committee criticises the government for planning to award covert subsidies to nuclear power, betraying the coalition promise that the taxpayer would not foot the bill for a new generation of reactors.In an interim report following Fukushima, Mike Weightman, the nuclear chief inspector, says the UK is not at risk of similar disaster, and there is no need to alter plans for new nuclear plants.The government approves a controversial scheme to dump 250,000 tonnes a year of nuclear waste at King's Cliffe, a traditional landfill site near Peterborough.June 2011 Huhne confirms the list of eight new sites for the next generation of nuclear power stations.July 2011 Fergus Ewing, Scotland's energy minister, says the SNP government is "open" to extending the use of the country's two existing nuclear plants, Hunterston and Torness, in a move away from SNP opposition to nuclear power.The government publishes its plans on reform of the electricity market, which will rely heavily on nuclear power.Despite local opposition, officials give the go-ahead for work to begin on Hinkley C in Somerset, the first new nuclear power station for 20 years.The History of Nuclear TechnologyBefore the second world war some important investigations in nuclear physics led to the discovery of the nuclear fission of heavy nuclei. The first proven nuclear fission was performed by Otto Hahn in Germany in 1939.
The political situation in the world during the second world war demanded the rapid development of nuclear weapons technology in the United States.
On 2 December 1942researchers under the leadership of Enrico Fermi managed to maintain thefirst controlled nuclear chain reaction in an experimental device calledChicago Pile 1. This was a very huge composite of uranium and graphite. The reaction was maintained for 28 minutes.
In the first years after the discovery of the chain reaction, nuclear energy was used only for military purposes. Only after the war was development turned in the direction of the peaceful use of nuclear energy for the production of electricity.
In 1946 the Americain Congress passed the very important Atomic Energy Act which enabled the development of nuclear power for peaceful purposes.
In December 1951 the first four electric bulbs were illuminated by electricity which was produced by the nuclear reactor EBR-1 in Idaho Falls in the United States. This was the first experimental breeder reactor.
There was a parallel development of the pressurized water reactor, which was first designed for the propulsion of submarines. It was successfully tested in 1953. The first nuclear submarines were the Nautilus and the Seawolf.
In the 1954 in Obininsk in the Soviet Union the firstnuclear power plant in the world was successfully started: APS-1. It produced only 5 MW of electric power. It was graphite moderated and marks the beginning of the later RBMK type reactors.
On 17 July 1955 the experimental boiling reactor BORAX-III produced for the first time enough electricity to illuminate the city of Arco in Idaho, United States.
On 17 October 1956 thefirst gas-cooled nuclear power plant was started in Calder Hall in Great Britain. This was the beginning of the British nuclear programme.
In 1956 the first commercial nuclear power plant, Shippingport in the USA was started. The second one, Yankee-Rowe was built in 1960 in Massachusetts. They both used pressurized water reactors and were constructed by Westinghouse.
In 1960 the General Electric company started the firstcommecial boiling water nuclear power plant, Dresden near Chicago in the United States of America.
In 1962 the first Canadian nuclear power plant, NPDwas started. It used natural uranium and heavy water.
The first nuclear power plant in France was built under American licence in 1965.
The first power plants started the era of commercial use of the nuclear fission for the production of electricity.More about history at ourexhibition.
