Liberty Leading the People

Liberty Leading the People (La Liberté guidant le peuple ) is a painting of the Romantic era by the French artist Eugène Delacroix, commemorating the July Revolution of 1830 that toppled King Charles X. A bare-breasted woman of the people with a Phrygian cap personifying the concept and Goddess of Liberty leads a varied group of people forward over a barricade and the bodies of the fallen, holding aloft the flag of the French Revolution – the tricolour, which again became France's national flag after these events – in one hand and brandishing a bayonetted musket with the other. The figure of Liberty is also viewed as a symbol of France and the French Republic known as Marianne. The painting is sometimes wrongly thought to depict the French Revolution of 1789.

Liberty Leading the People is exhibited in the Louvre in Paris.

History
By the time Delacroix painted Liberty Leading the People, he was already the acknowledged leader of the Romantic school in French painting. Delacroix, who was born as the Age of Enlightenment was giving way to the ideas and style of romanticism, rejected the emphasis on precise drawing that characterised the academic art of his time, and instead gave a new prominence to freely brushed colour.

Delacroix painted his work in the autumn of 1830. In a letter to his brother dated 21 October, he wrote: "My bad mood is vanishing thanks to hard work. I've embarked on a modern subject—a barricade. And if I haven't fought for my country at least I'll paint for her." The painting was first exhibited at the official Salon of 1831.

Symbolism
Delacroix depicted Liberty as both an allegorical goddess-figure and a robust woman of the people. The mound of corpses and wreckage acts as a kind of pedestal from which Liberty strides, barefoot and bare-breasted, out of the canvas and into the space of the viewer. The Phrygian cap she wears had come to symbolize liberty during the first French Revolution, of 1789. The painting has been seen as a marker to the end of the Age of Enlightenment, as many scholars see the end of the French Revolution as the start of the Romantic era.

The fighters are from a mixture of social classes, ranging from the bourgeoisie represented by the young man in a top hat, a student from the prestigious École Polytechnique wearing the traditional bicorne, to the revolutionary urban worker, as exemplified by the boy holding pistols. What they have in common is the fierceness and determination in their eyes. Aside from the flag held by Liberty, a second, minute tricolore can be discerned in the distance flying from the towers of Notre-Dame.

The identity of the man in the top hat has been widely debated. The suggestion that it was a self-portrait by Delacroix has been discounted by modern art historians. In the late 19th century, it was suggested the model was the theatre director Étienne Arago; others have suggested the future curator of the Louvre, Frédéric Villot; but there is no firm consensus on this point.

Several of the figures are probably borrowed from a print by popular artist Nicolas Charlet, a prolific illustrator who Delacroix believed captured, more than anyone else, the peculiar energy of the Parisians.

Purchase and exhibition
The French government bought the painting in 1831 for 3,000 francs with the intention of displaying it in the throne room of the Palais du Luxembourg as a reminder to the "citizen-king" Louis-Philippe of the July Revolution, through which he had come to power. This plan did not come to fruition and the canvas hung in the palace's museum gallery for a few months, before being removed due to its inflammatory political message. After the June Rebellion of 1832, it was returned to the artist. According to Albert Boime,

"Champfleury wrote in August 1848 that it had been 'hidden in an attic for being too revolutionary.' Although Louis-Philippe's Ministry of the Interior initially acquired it as a gesture to the Left, after the uprising at the funeral of Lamarque in June 1832 it was never again openly displayed for fear of setting a bad example." Delacroix was permitted to send the painting to his aunt Félicité for safekeeping. After the Second Republic was established following the revolution of 1848 it was exhibited briefly in that year, and then during the Second Empire in the Salon of 1855. The recently established Third Republic finally acquired the painting in 1874 for the collection of the Musée du Louvre in Paris.

In 1974–75, the painting was the featured work in an exhibition organized by the French government, the Metropolitan Museum of Art in New York and the Detroit Institute of Arts as a Bicentennial gift to the people of the United States. The exhibition, entitled French Painting 1774–1830: The Age of Revolution, marked a rare display of the Delacroix painting, and many of the other 148 works, outside France. The exhibition was first shown at the Grand Palais from 16 November 1974 to 3 February 1975. It moved to Detroit from 5 March to 4 May 1975, then New York from 12 June to 7 September 1975.

In 1999, it was flown on board an Airbus Beluga from Paris to Tokyo via Bahrain and Calcutta in about 20 hours. The large canvas, measuring 2.99 m high by 3.62 m long, was too large to fit into a Boeing 747. It was transported in the vertical position inside a special pressurised container provided with isothermal protection and an anti-vibration device.

In 2012, it was moved to the new Louvre-Lens museum in Lens, Pas-de-Calais, as the starring work in the first tranche of paintings from the Louvre's collection to be installed. On 7 February 2013, the painting was vandalized by a visitor in Lens. An unidentified 28-year-old woman allegedly wrote an inscription ("AE911") on the painting. The woman was immediately arrested by a security guard and a visitor. A short time after the incident, the management of the Louvre and its Pas-de-Calais branch published a press release indicating that "at first glance, the inscription is superficial and should be easily removed". Louvre officials announced the next day that the writing had been removed in less than two hours by a restorer without damaging the original paint, and the piece returned to display that morning.

Legacy
Although Delacroix was not the first artist to depict Liberty in a Phrygian cap, his painting may be the best known early version of the figure commonly known as Marianne, a symbol of the French Republic and of France in general.

The painting may have influenced Victor Hugo's 1862 novel Les Misérables. In particular, the character of Gavroche is widely believed to have been inspired by the figure of the pistols-wielding boy running over the barricade. The novel describes the events of the June Rebellion two years after the revolution celebrated in the painting, the same rebellion that led to its being removed from public view.

The painting inspired Frédéric Auguste Bartholdi's Liberty Enlightening the World, known as the Statue of Liberty in New York City, which was given to the United States as a gift from the French a half-century after Liberty Leading the People was painted. The statue, which holds a torch in its hand, takes a more stable, immovable stance than that of the woman in the painting. An engraved version of part of the painting, along with a depiction of Delacroix, was featured on the 100 franc note from 1978 to 1995.

The painting has had an influence on classical music. George Antheil titled his Symphony No. 6 After Delacroix, and stated that the work was inspired by Liberty Leading the People. The imagery was adapted by Robert Ballagh to commemorate Ireland's independence struggle on an Irish postage stamp in 1979, the centenary of the birth of Pádraig Pearse, and the painting was used for the band Coldplay's 2008 album cover Viva la Vida or Death and All His Friends, with the words Viva La Vida written in white. Rigoberta Bandini references the painting in the chorus of her 2021 song Ay mamá. The cover of the 2010 book Enough is Enough: How to Build a New Republic by Fintan O'Toole references the painting, but with Kathleen Ni Houlihan holding the Irish tricolour in Dublin while the leaders of the three main political parties at the time (Brian Cowen, Enda Kenny and Eamon Gilmore) lie on the ground.

During the 20 October 2011 episode of the BBC Radio 4 series In Our Time, host Melvyn Bragg led a panel discussion of the painting.

Liberty Leading the People made an appearance in the 11th episode ("EDGELORD – Revolution of the 14-Year-Olds") of the Netflix animation series Ghost in the Shell: SAC 2045.

The painting was featured in Vincenzo, a 2021 South Korean TV series starring Song Joong-ki in episode 7. The series is also available on Netflix.

A photograph of Aed Abu Amro taken during the 2018–2019 Gaza border protests by Mustafa Hassona on 22 October 2018, was considered by some a personification of the Liberty Leading the People.

Libery Leading the People makes a prominent appearance in the 2023 film John Wick Chapter 4, starring Keanu Reeves. Near the end of the second act, main antagonist, Marquis Vincent de Garmont (Bill Skarsgård) is seen standing before Liberty Leading the People inside the Louvre Museum, which was famously closed to the public for the filming of the scenes.

Criticism
Liberty Leading the People is considered a republican and anti-monarchist symbol, and as such was sometimes criticized by royalists and monarchists.

Nuclear and radiation accidents and incidents

A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or a reactor core melt. The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011.

The impact of nuclear accidents has been a topic of debate since the first nuclear reactors were constructed in 1954 and has been a key factor in public concern about nuclear facilities. Technical measures to reduce the risk of accidents or to minimize the amount of radioactivity released to the environment have been adopted, however human error remains, and "there have been many accidents with varying impacts as well near misses and incidents". As of 2014, there have been more than 100 serious nuclear accidents and incidents from the use of nuclear power. Fifty-seven accidents or severe incidents have occurred since the Chernobyl disaster, and about 60% of all nuclear-related accidents/severe incidents have occurred in the USA. Serious nuclear power plant accidents include the Fukushima nuclear disaster (2011), the Chernobyl disaster (1986), the Three Mile Island accident (1979), and the SL-1 accident (1961). Nuclear power accidents can involve loss of life and large monetary costs for remediation work.

Nuclear submarine accidents include the K-19 (1961), K-11 (1965), K-27 (1968), K-140 (1968), K-429 (1970), K-222 (1980), and K-431 (1985) accidents. Serious radiation incidents/accidents include the Kyshtym disaster, the Windscale fire, the radiotherapy accident in Costa Rica, the radiotherapy accident in Zaragoza, the radiation accident in Morocco, the Goiania accident, the radiation accident in Mexico City, the Samut Prakan radiation accident, and the Mayapuri radiological accident in India.

The IAEA maintains a website reporting recent nuclear accidents.

In 2020, the WHO stated that "Lessons learned from past radiological and nuclear accidents have demonstrated that the mental health and psychosocial consequences can outweigh the direct physical health impacts of radiation exposure." "

Nuclear plant accidents

The world's first nuclear reactor meltdown was the NRX reactor at Chalk River Laboratories, Ontario, Canada in 1952.

The worst nuclear accident to date is the Chernobyl disaster which occurred in 1986 in the Ukrainian SSR, now Ukraine. The accident killed approximately 30 people directly and damaged approximately $7 billion of property. A study published in 2005 by the World Health Organization estimates that there may eventually be up to 4,000 additional cancer deaths related to the accident among those exposed to significant radiation levels. Radioactive fallout from the accident was concentrated in areas of Belarus, Ukraine and Russia. Other studies have estimated as many as over a million eventual cancer deaths from Chernobyl. Estimates of eventual deaths from cancer are highly contested. Industry, UN and DOE agencies claim low numbers of legally provable cancer deaths will be traceable to the disaster. The UN, DOE and industry agencies all use the limits of the epidemiological resolvable deaths as the cutoff below which they cannot be legally proven to come from the disaster. Independent studies statistically calculate fatal cancers from dose and population, even though the number of additional cancers will be below the epidemiological threshold of measurement of around 1%. These are two very different concepts and lead to the huge variations in estimates. Both are reasonable projections with different meanings. Approximately 350,000 people were forcibly resettled away from these areas soon after the accident. 6,000 people were involved in cleaning Chernobyl and 10,800 sqmi were contaminated.

Social scientist and energy policy expert, Benjamin K. Sovacool has reported that worldwide there have been 99 accidents at nuclear power plants from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define major energy accidents that must be reported), totaling US$20.5 billion in property damages. There have been comparatively few fatalities associated with nuclear power plant accidents. An academic review of many reactor accident and the phenomena of these events was published by Mark Foreman.

Nuclear reactor attacks
The vulnerability of nuclear plants to deliberate attack is of concern in the area of nuclear safety and security. Nuclear power plants, civilian research reactors, certain naval fuel facilities, uranium enrichment plants, fuel fabrication plants, and even potentially uranium mines are vulnerable to attacks which could lead to widespread radioactive contamination. The attack threat is of several general types: commando-like ground-based attacks on equipment which if disabled could lead to a reactor core meltdown or widespread dispersal of radioactivity; and external attacks such as an aircraft crash into a reactor complex, or cyber attacks.

The United States 9/11 Commission found that nuclear power plants were potential targets originally considered as part of the September 11 attacks. If terrorist groups could sufficiently damage safety systems to cause a core meltdown at a nuclear power plant, or sufficiently damage spent fuel pools, such an attack could lead to widespread radioactive contamination. The Federation of American Scientists have said that if nuclear power use is to expand significantly, nuclear facilities will have to be made extremely safe from attacks that could release radioactivity into the environment. New reactor designs have features of passive nuclear safety, which may help. In the United States, the NRC carries out "Force on Force" (FOF) exercises at all Nuclear Power Plant (NPP) sites at least once every three years.

Nuclear reactors become preferred targets during military conflict and have been repeatedly attacked during military air strikes, occupations, invasions and campaigns over the period 1980–2007. Various acts of civil disobedience since 1980 by the peace group Plowshares have shown how nuclear weapons facilities can be penetrated, and the group's actions represent extraordinary breaches of security at nuclear weapons plants in the United States. The National Nuclear Security Administration has acknowledged the seriousness of the 2012 Plowshares action. Non-proliferation policy experts have questioned "the use of private contractors to provide security at facilities that manufacture and store the government's most dangerous military material". Nuclear weapons materials on the black market are a global concern, and there is concern about the possible detonation of a small, crude nuclear weapon or dirty bomb by a militant group in a major city, causing significant loss of life and property.

The number and sophistication of cyber attacks is on the rise. Stuxnet is a computer worm discovered in June 2010 that is believed to have been created by the United States and Israel to attack Iran's nuclear facilities. It switched off safety devices, causing centrifuges to spin out of control. The computers of South Korea's nuclear plant operator (KHNP) were hacked in December 2014. The cyber attacks involved thousands of phishing emails containing malicious codes, and information was stolen.

In March 2022, the Battle of Enerhodar caused damage to the Zaporizhzhia Nuclear Power Plant and a fire at its training complex as Russian forces took control, heightening concerns of nuclear contamination. On September 6, 2022, IAEA Director General Rafael Grossi addressed the UN Security Council, calling for a nuclear safety and security protection zone around the plant and reiterating his findings that "the Seven Pillars [for nuclear safety and security] have all been compromised at the site."

Radiation and other accidents and incidents

Serious radiation and other accidents and incidents include:
 * 1940s
 * May 1945: Albert Stevens was one of several subjects of a human radiation experiment, and was injected with plutonium without his knowledge or informed consent. Although Stevens was the person who received the highest dose of radiation during the plutonium experiments, he was neither the first nor the last subject to be studied. Eighteen people aged 4 to 69 were injected with plutonium. Subjects who were chosen for the experiment had been diagnosed with a terminal disease. They lived from 6 days up to 44 years past the time of their injection. Eight of the 18 died within two years of the injection. Although one cause of death was unknown, a report by William Moss and Roger Eckhardt concluded that there was "no evidence that any of the patients died for reasons that could be attributed to the plutonium injections. Patients from Rochester, Chicago, and Oak Ridge were also injected with plutonium in the Manhattan Project human experiments.
 * 6–9 August 1945: On the orders of President Harry S. Truman, a uranium-gun design bomb, Little Boy, was used against the city of Hiroshima, Japan. Fat Man, a plutonium implosion-design bomb was used against the city of Nagasaki. The two weapons killed approximately 120,000 to 140,000 civilians and military personnel instantly and thousands more have died over the years from radiation sickness and related cancers.
 * August 1945: Criticality accident at US Los Alamos National Laboratory. Harry Daghlian dies.

 * 21 May 1957: Mayak, former Soviet Union. Criticality accident in the factory number 20 in the collection oxalate decantate after filtering sediment oxalate enriched uranium. Six people received doses of 300 to 1,000 rem (four women and two men), one woman died.
 * 29 September 1957: Kyshtym disaster: Nuclear waste storage tank explosion at the same Mayak plant, Russia. No immediate fatalities, though up to 200+ additional cancer deaths might have ensued from the radioactive contamination of the surrounding area; 270,000 people were exposed to dangerous radiation levels. Over thirty small communities were removed from Soviet maps between 1958 and 1991. (INES level 6)
 * October 1957: Windscale fire, UK. Fire ignites a "plutonium pile" (an air cooled, graphite moderated, uranium fuelled reactor that was used for plutonium and isotope production) and contaminates surrounding dairy farms. An estimated 33 cancer deaths.
 * 1957-1964: Rocketdyne located at the Santa Susanna Field Lab, 30 miles north of Los Angeles, California operated ten experimental nuclear reactors. Numerous accidents occurred including a core meltdown. Experimental reactors of that era were not required to have the same type of containment structures that shield modern nuclear reactors. During the Cold War time in which the accidents that occurred at Rocketdyne, these events were not publicly reported by the Department of Energy.
 * 1958: Fuel rupture and fire at the National Research Universal reactor (NRU), Chalk River, Canada.
 * 10 February 1958: Mayak, former Soviet Union. Criticality accident in SCR plant. Conducted experiments to determine the critical mass of enriched uranium in a cylindrical container with different concentrations of uranium in solution. Staff broke the rules and instructions for working with YADM (nuclear fissile material). When SCR personnel received doses from 7,600 to 13,000 rem. Three people died, one man got radiation sickness and went blind.
 * 15 October 1958: Vinča, Yugoslavia. There was a criticality incident in a newly installed reactor. Six young researchers received high doses of radiation, and were subsequently treated at "Kiri" institute in Paris where one of them died.
 * 30 December 1958: Cecil Kelley criticality accident at Los Alamos National Laboratory.

 * July 1959: Santa Susana Field Laboratory, Los Angeles, California. Partial meltdown.
 * October 15, 1959, a B-52 carrying two nuclear weapons collided in midair with a KC-135 tanker near Hardinsburg, Kentucky. One of the nuclear bombs was damaged by fire but both weapons were recovered.
 * 1960's
 * 7 June 1960: the 1960 Fort Dix IM-99 accident destroyed a CIM-10 Bomarc nuclear missile and shelter and contaminated the BOMARC Missile Accident Site in New Jersey.
 * 24 January 1961: the 1961 Goldsboro B-52 crash occurred near Goldsboro, North Carolina. A B-52 Stratofortress carrying two Mark 39 nuclear bombs broke up in mid-air, dropping its nuclear payload in the process.
 * July 1961: soviet submarine K-19 accident. Eight fatalities and more than 30 people were over-exposed to radiation.
 * July 6, 1962 Sedan nuclear test accidentally released 33 PBq of radioactive iodine-131 and other radioactive material.
 * 21 March–August 1962: radiation accident in Mexico City, four fatalities.
 * 23 July 1964: Wood River Junction criticality accident. Resulted in 1 fatality
 * 1964, 1969: Santa Susana Field Laboratory, Los Angeles, California. Partial meltdowns.
 * 1965 Philippine Sea A-4 crash, where a Skyhawk attack aircraft with a nuclear weapon fell into the sea. The pilot, the aircraft, and the B43 nuclear bomb were never recovered. It was not until the 1980s that the Pentagon revealed the loss of the one-megaton bomb.
 * October 1965: US CIA-led expedition abandons a nuclear-powered telemetry relay listening device on Nanda Devi
 * 17 January 1966: the 1966 Palomares B-52 crash occurred when a B-52G bomber of the USAF collided with a KC-135 tanker during mid-air refuelling off the coast of Spain. The KC-135 was completely destroyed when its fuel load ignited, killing all four crew members. The B-52G broke apart, killing three of the seven crew members aboard. Of the four Mk28 type hydrogen bombs the B-52G carried, three were found on land near Almería, Spain. The non-nuclear explosives in two of the weapons detonated upon impact with the ground, resulting in the contamination of a 2 km2 (0.78 square mile) area by radioactive plutonium. The fourth, which fell into the Mediterranean Sea, was recovered intact after a 2$1/2$-month-long search.
 * 21 January 1968: the 1968 Thule Air Base B-52 crash involved a United States Air Force (USAF) B-52 bomber. The aircraft was carrying four hydrogen bombs when a cabin fire forced the crew to abandon the aircraft. Six crew members ejected safely, but one who did not have an ejection seat was killed while trying to bail out. The bomber crashed onto sea ice in Greenland, causing the nuclear payload to rupture and disperse, which resulted in widespread radioactive contamination.
 * May 1968: Soviet submarine K-27 reactor near meltdown. 9 people died, 83 people were injured.
 * In August 1968: Soviet nuclear ballistic missile submarine development program Project 667A. Nuclear-powered Yankee class submarine K-140 was in the naval yard at Severodvinsk for repairs. On August 27, an uncontrolled increase of the reactor's power occurred following work to upgrade the vessel. One of the reactors started up automatically when the control rods were raised to a higher position. Power increased to 18 times its normal amount, while pressure and temperature levels in the reactor increased to four times the normal amount. The automatic start-up of the reactor was caused by the incorrect installation of the control rod electrical cables and by operator error. Radiation levels aboard the vessel deteriorated.
 * 10 December 1968: Mayak, former Soviet Union. Criticality accident. Plutonium solution was poured into a cylindrical container with dangerous geometry. One person died, another took a high dose of radiation and radiation sickness, after which he had two legs and his right arm amputated.

Worldwide nuclear weapons testing summary

Between 16 July 1945 and 23 September 1992, the United States maintained a program of vigorous nuclear weapons testing, with the exception of a moratorium between November 1958 and September 1961. By official count, a total of 1,054 nuclear tests and two nuclear attacks were conducted, with over 100 of them taking place at sites in the Pacific Ocean, over 900 of them at the Nevada Test Site, and ten on miscellaneous sites in the United States (Alaska, Colorado, Mississippi, and New Mexico). Until November 1962, the vast majority of the U.S. tests were atmospheric (that is, above-ground); after the acceptance of the Partial Test Ban Treaty all testing was regulated underground, in order to prevent the dispersion of nuclear fallout.

The U.S. program of atmospheric nuclear testing exposed a number of the population to the hazards of fallout. Estimating exact numbers, and the exact consequences, of people exposed has been medically very difficult, with the exception of the high exposures of Marshall Islanders and Japanese fishers in the case of the Castle Bravo incident in 1954. A number of groups of U.S. citizens — especially farmers and inhabitants of cities downwind of the Nevada Test Site and U.S. military workers at various tests — have sued for compensation and recognition of their exposure, many successfully. The passage of the Radiation Exposure Compensation Act of 1990 allowed for a systematic filing of compensation claims in relation to testing as well as those employed at nuclear weapons facilities. As of June 2009 over $1.4 billion total has been given in compensation, with over $660 million going to "downwinders".

Trafficking and thefts
For intentional or attempted theft of radioactive material, See Crimes involving radioactive substances

The International Atomic Energy Agency says there is "a persistent problem with the illicit trafficking in nuclear and other radioactive materials, thefts, losses and other unauthorized activities". The IAEA Illicit Nuclear Trafficking Database notes 1,266 incidents reported by 99 countries over the last 12 years, including 18 incidents involving HEU or plutonium trafficking:

 * Security specialist Shaun Gregory argued in an article that terrorists have attacked Pakistani nuclear facilities three times in the recent past; twice in 2007 and once in 2008.
 * In November 2007, burglars with unknown intentions infiltrated the Pelindaba nuclear research facility near Pretoria, South Africa. The burglars escaped without acquiring any of the uranium held at the facility.
 * In February 2006, Oleg Khinsagov of Russia was arrested in Georgia, along with three Georgian accomplices, with 79.5 grams of 89 percent enriched HEU.
 * The Alexander Litvinenko poisoning in November 2006 with radioactive polonium "represents an ominous landmark: the beginning of an era of nuclear terrorism," according to Andrew J. Patterson.

Nuclear meltdown
A nuclear meltdown is a severe nuclear reactor accident that results in reactor core damage from overheating. It has been defined as the accidental melting of the core of a nuclear reactor, and refers to the core's either complete or partial collapse. A core melt accident occurs when the heat generated by a nuclear reactor exceeds the heat removed by the cooling systems to the point where at least one nuclear fuel element exceeds its melting point. This differs from a fuel element failure, which is not caused by high temperatures. A meltdown may be caused by a loss of coolant, loss of coolant pressure, or low coolant flow rate or be the result of a criticality excursion in which the reactor is operated at a power level that exceeds its design limits. Alternately, an external fire may endanger the core, leading to a meltdown.

Large-scale nuclear meltdowns at civilian nuclear power plants include:

 * the Three Mile Island accident in Pennsylvania, United States, in 1979.
 * the Chernobyl disaster at Chernobyl Nuclear Power Plant, Ukraine, USSR, in 1986.
 * the Fukushima Daiichi nuclear disaster following the earthquake and tsunami in Japan, March 2011.

Other core meltdowns have occurred at:
 * NRX (military), Ontario, Canada, in 1952
 * BORAX-I (experimental), Idaho, United States, in 1954
 * EBR-I, Idaho, United States, in 1955
 * Windscale (military), Sellafield, England, in 1957 (see Windscale fire)
 * Sodium Reactor Experiment, Santa Susana Field Laboratory (civilian), California, United States, in 1959
 * Fermi 1 (civilian), Michigan, United States, in 1966
 * Chapelcross nuclear power station (civilian), Scotland, in 1967
 * the Lucens reactor, Switzerland, in 1969.
 * Saint-Laurent Nuclear Power Plant (civilian), France, in 1969
 * A1 plant, (civilian) at Jaslovské Bohunice, Czechoslovakia, in 1977
 * Saint-Laurent Nuclear Power Plant (civilian), France, in 1980
 * Several Soviet Navy nuclear submarines have had nuclear core melts: K-19 (1961), K-11(1965), K-27 (1968), K-140 (1968), K-222 (1980), and K-431 (1985).

Criticality accidents
A criticality accident (also sometimes referred to as an "excursion" or "power excursion") occurs when a nuclear chain reaction is accidentally allowed to occur in fissile material, such as enriched uranium or plutonium. The Chernobyl accident is not universally regarded an example of a criticality accident, because it occurred in an operating reactor at a power plant. The reactor was supposed to be in a controlled critical state, but control of the chain reaction was lost. The accident destroyed the reactor and left a large geographic area uninhabitable. In a smaller scale accident at Sarov a technician working with highly enriched uranium was irradiated while preparing an experiment involving a sphere of fissile material. The Sarov accident is interesting because the system remained critical for many days before it could be stopped, though safely located in a shielded experimental hall. This is an example of a limited scope accident where only a few people can be harmed, while no release of radioactivity into the environment occurred. A criticality accident with limited off site release of both radiation (gamma and neutron) and a very small release of radioactivity occurred at Tokaimura in 1999 during the production of enriched uranium fuel. Two workers died, a third was permanently injured, and 350 citizens were exposed to radiation. In 2016, a criticality accident was reported at the Afrikantov OKBM Critical Test Facility in Russia.

Decay heat
Decay heat accidents are where the heat generated by radioactive decay causes harm. In a large nuclear reactor, a loss of coolant accident can damage the core: for example, at Three Mile Island Nuclear Generating Station a recent shutdown (SCRAMed) PWR reactor was left for a length of time without cooling water. As a result, the nuclear fuel was damaged, and the core partially melted. The removal of the decay heat is a significant reactor safety concern, especially shortly after shutdown. Failure to remove decay heat may cause the reactor core temperature to rise to dangerous levels and has caused nuclear accidents. The heat removal is usually achieved through several redundant and diverse systems, and the heat is often dissipated to an 'ultimate heat sink' which has a large capacity and requires no active power, though this method is typically used after decay heat has reduced to a very small value. The main cause of the release of radioactivity in the Three Mile Island accident was a pilot-operated relief valve on the primary loop which stuck in the open position. This caused the overflow tank into which it drained to rupture and release large amounts of radioactive cooling water into the containment building.

For the most part, nuclear facilities receive their power from offsite electrical systems. They also have a grid of emergency backup generators to provide power in the event of an outage. An event that could prevent both offsite power, as well as emergency power is known as a "station blackout". In 2011, an earthquake and tsunami caused a loss of electric power at the Fukushima Daiichi nuclear power plant in Japan (via severing the connection to the external grid and destroying the backup diesel generators). The decay heat could not be removed, and the reactor cores of units 1, 2 and 3 overheated, the nuclear fuel melted, and the containments were breached. Radioactive materials were released from the plant to the atmosphere and to the ocean.

Transport
Transport accidents can cause a release of radioactivity resulting in contamination or shielding to be damaged resulting in direct irradiation. In Cochabamba a defective gamma radiography set was transported in a passenger bus as cargo. The gamma source was outside the shielding, and it irradiated some bus passengers.

In the United Kingdom, it was revealed in a court case that in March 2002 a radiotherapy source was transported from Leeds to Sellafield with defective shielding. The shielding had a gap on the underside. It is thought that no human has been seriously harmed by the escaping radiation.

On 17 January 1966, a fatal collision occurred between a B-52G and a KC-135 Stratotanker over Palomares, Spain (see 1966 Palomares B-52 crash). The accident was designated a "Broken Arrow", meaning an accident involving a nuclear weapon that does not present a risk of war.

Equipment failure
Equipment failure is one possible type of accident. In Białystok, Poland, in 2001 the electronics associated with a particle accelerator used for the treatment of cancer suffered a malfunction. This then led to the overexposure of at least one patient. While the initial failure was the simple failure of a semiconductor diode, it set in motion a series of events which led to a radiation injury.

A related cause of accidents is failure of control software, as in the cases involving the Therac-25 medical radiotherapy equipment: the elimination of a hardware safety interlock in a new design model exposed a previously undetected bug in the control software, which could have led to patients receiving massive overdoses under a specific set of conditions.

Human error
Some major nuclear accidents were attributable in part to operator or human error. At Chernobyl, operators deviated from test procedure and allowed certain reactor parameters to exceed design limits. At TMI-2, operators permitted thousands of gallons of water to escape from the reactor plant before observing that the coolant pumps were behaving abnormally. The coolant pumps were thus turned off to protect the pumps, which in turn led to the destruction of the reactor itself as cooling was completely lost within the core.

A detailed investigation into SL-1 determined that one operator (perhaps inadvertently) manually pulled the 84 lb central control rod out about 26 inches rather than the maintenance procedure's intention of about 4 inches.

An assessment conducted by the Commissariat à l'Énergie Atomique (CEA) in France concluded that no amount of technical innovation can eliminate the risk of human-induced errors associated with the operation of nuclear power plants. Two types of mistakes were deemed most serious: errors committed during field operations, such as maintenance and testing, that can cause an accident; and human errors made during small accidents that cascade to complete failure.

In 1946 Canadian Manhattan Project physicist Louis Slotin performed a risky experiment known as "tickling the dragon's tail" which involved two hemispheres of neutron-reflective beryllium being brought together around a plutonium core to bring it to criticality. Against operating procedures, the hemispheres were separated only by a screwdriver. The screwdriver slipped and set off a chain reaction criticality accident filling the room with harmful radiation and a flash of blue light (caused by excited, ionized air particles returning to their unexcited states). Slotin reflexively separated the hemispheres in reaction to the heat flash and blue light, preventing further irradiation of several co-workers present in the room. However, Slotin absorbed a lethal dose of the radiation and died nine days later. The infamous plutonium mass used in the experiment was referred to as the demon core.

Lost source
Lost source accidents, also referred to as orphan sources, are incidents in which a radioactive source is lost, stolen or abandoned. The source then might cause harm to humans. The best known example of this type of event is the 1987 Goiânia accident in Brazil, when a radiotherapy source was forgotten and abandoned in a hospital, to be later stolen and opened by scavengers. A similar case occurred in 2000 in Samut Prakan, Thailand when the radiation source of an expired teletherapy unit was sold unregistered, and stored in an unguarded car park from which it was stolen. Other cases occurred at Yanango, Peru where a radiography source was lost, and Gilan, Iran where a radiography source harmed a welder.

The International Atomic Energy Agency has provided guides for scrap metal collectors on what a sealed source might look like. The scrap metal industry is the one where lost sources are most likely to be found.

Experts believe that up to 50 nuclear weapons were lost during the Cold War.

Comparisons
Comparing the historical safety record of civilian nuclear energy with other forms of electrical generation, Ball, Roberts, and Simpson, the IAEA, and the Paul Scherrer Institute found in separate studies that during the period from 1970 to 1992, there were just 39 on-the-job deaths of nuclear power plant workers worldwide, while during the same time period, there were 6,400 on-the-job deaths of coal power plant workers, 1,200 on-the-job deaths of natural gas power plant workers and members of the general public caused by natural gas power plants, and 4,000 deaths of members of the general public caused by hydroelectric power plants  with failure of Banqiao Dam in 1975 resulting in 170,000-230,000 fatalities alone.

As other common sources of energy, coal power plants are estimated to kill 24,000 Americans per year due to lung disease as well as causing 40,000 heart attacks per year in the United States. According to Scientific American, the average coal power plant emits 100 times more radiation per year than a comparatively sized nuclear power plant in the form of toxic coal waste known as fly ash.

In terms of energy accidents, hydroelectric plants were responsible for the most fatalities, but nuclear power plant accidents rank first in terms of their economic cost, accounting for 41 percent of all property damage. Oil and hydroelectric follow at around 25 percent each, followed by natural gas at 9 percent and coal at 2 percent. Excluding Chernobyl and the Shimantan Dam, the three other most expensive accidents involved the Exxon Valdez oil spill (Alaska), the Prestige oil spill (Spain), and the Three Mile Island nuclear accident (Pennsylvania).

Nuclear safety
Nuclear safety covers the actions taken to prevent nuclear and radiation accidents or to limit their consequences and damage to the environment. This covers nuclear power plants as well as all other nuclear facilities, the transportation of nuclear materials, and the use and storage of nuclear materials for medical, power, industry, and military uses.

The nuclear power industry has improved the safety and performance of reactors, and has proposed new safer (but generally untested) reactor designs but there is no guarantee that the reactors will be designed, built and operated correctly. Mistakes do occur and the designers of reactors at Fukushima in Japan did not anticipate that a tsunami generated by an earthquake would disable the backup systems that were supposed to stabilize the reactor after the earthquake. According to UBS AG, the Fukushima I nuclear accidents have cast doubt on whether even an advanced economy like Japan can master nuclear safety. Catastrophic scenarios involving terrorist attacks are also conceivable.

In his book Normal Accidents, Charles Perrow says that unexpected failures are built into society's complex and tightly coupled nuclear reactor systems. Nuclear power plants cannot be operated without some major accidents. Such accidents are unavoidable and cannot be designed around. An interdisciplinary team from MIT have estimated that given the expected growth of nuclear power from 2005 to 2055, at least four serious nuclear accidents would be expected in that period. There have been five serious accidents (core damage) in the world since 1970 (one at Three Mile Island in 1979; one at Chernobyl in 1986; and three at Fukushima-Daiichi in 2011), corresponding to the beginning of the operation of generation II reactors. This leads to on average one serious accident happening every eight years worldwide.

When nuclear reactors begin to age, they require more exhaustive monitoring and preventive maintenance and tests to operate safely and prevent accidents. However, these measures can be costly, and some reactor owners have not followed these recommendations. Most of the existing nuclear infrastructure in use is old due to these reasons.

To combat accidents associated with aging nuclear power plants, it may be advantageous to build new nuclear power reactors and retire the old nuclear plants. In the United States alone, more than 50 start-up companies are working to create innovative designs for nuclear power plants while ensuring the plants are more affordable and cost-effective.

Impact on land
Isotopes released during a meltdown or related event are typically dispersed into the atmosphere and then settle on the surface through natural occurrences and deposition. Isotopes settling on the top soil layer can remain there for many years, due to their slow decay (long half-life). The long-term detrimental effects on agriculture, farming, and livestock, can potentially affect human health and safety long after the actual event.

After the Fukushima Daiichi accident in 2011, surrounding agricultural areas were contaminated with more than 100,000 MBq km−2 in cesium concentrations. As a result, eastern Fukushima food production was severely limited. Due to Japan's topography and the local weather patterns, cesium deposits as well as other isotopes reside in top layer of soils all over eastern and northeastern Japan. Luckily, mountain ranges have shielded western Japan.

The Chernobyl disaster in 1986 exposed to radiation about 125,000 mi2 (320,000 km2) of land across Ukraine, Belarus, and Russia. The amount of focused radiation caused severe damage to plant reproduction: most plants could not reproduce for at least three years. Many of these occurrences on land can be a result of the distribution of radioactive isotopes through water systems.

Fukushima Daiichi accident
In 2013, contaminated groundwater was found in between some of the affected turbine buildings in the Fukushima Daiichi facility, including locations at bordering seaports on the Pacific Ocean. In both locations, the facility typically releases clean water to feed into further groundwater systems. The Tokyo Electric Power Company (TEPCO), the entity that manages and operates the facility, further investigated the contamination in areas that would be deemed safe to conduct operations. They found that a significant amount of the contamination originated from underground cable trenches that connected to circulation pumps within the facility. Both the International Atomic Energy Agency (IAEA) and TEPCO confirmed that this contamination was a result of the 2011 earthquake. Due to damage like this, the Fukushima plant released nuclear material into the Pacific Ocean and has continued to do so. After 5 years of leaking, the contaminates reached all corners of the Pacific Ocean, from North America and Australia to Patagonia. Along the same coastline, Woods Hole Oceanographic Institution (WHOI) found trace amounts of Fukushima contaminates 100 miles (150 km) off the coast of Eureka, California in November 2014. Despite the relatively dramatic increases in radiation, the contamination levels still satisfy the World Health Organization's (WHO's) standard for clean drinking water.

In 2019, the Japanese government announced that it was considering the possibility of dumping contaminated water from the Fukushima reactor into the Pacific Ocean. Japanese Environmental Minister Yoshiaki Harada reported that TEPCO had collected over a million tons of contaminated water, and by 2022 they would be out of space to safely store the radioactive water.

Multiple private agencies as well as various North American governments monitor the spread of radiation throughout the Pacific to track the potential hazards it can introduce to food systems, groundwater supplies, and ecosystems. In 2014, the United States Food and Drug Administration (FDA) released a report stating that radionuclides, traced from the Fukushima facility, were present in the United States food supply, but not to levels deemed to be a threat to public health – as well as any food and agricultural products imported from Japanese sources. It is commonly believed that, with the rate of the current radionuclide leakage, the dispersal into the water would prove beneficial, as most of the isotopes would be diluted by the water as well as become less radioactive over time, due to radioactive decay. Cesium (Cs-137) is the primary isotope released from the Fukushima Daiichi facility. Cs-137 has a long half-life, meaning it could potentially have long-term harmful effects, but as of now, its levels from 200 km outside of Fukushima show close to pre-accident levels, with little spread to North American coasts.

Chernobyl accident
Evidence can be seen from the 1986 Chernobyl event. Due to the violent nature of the accident there, a sizable portion of the resulting radioactive contamination of the atmosphere consisted of particles that were dispersed during the explosion. Many of these contaminates settled in groundwater systems in immediate surrounding areas, but also in Russia and Belarus. The ecological effects of the resulting radiation in groundwater can be seen in various aspects in the area affected by the sequence of environmental consequences. Radionuclides carried by groundwater systems have resulted in the uptake of radioactive material in plants and then up the food chains into animals, and eventually humans. One of the most important mechanisms of exposure to radiation was through agriculture contaminated by radioactive groundwater. Again, one of the greatest concerns for the population within the 30 km exclusion zone is the intake of Cs-137 by consuming agricultural products contaminated with groundwater. Thanks to the environmental and soil conditions outside the exclusion zone, the recorded levels are below those that require remediation, based on a survey in 1996. During this event, radioactive material was transported by groundwater across borders into neighboring countries. In Belarus, just north of Chernobyl, about 250,000 hectares of previously usable farmland were held by state officials until deemed safe.

Off-site radiological risk may be found in the form of flooding. Many citizens in the surrounding areas have been deemed at risk of exposure to radiation due to the Chernobyl reactor's proximity to floodplains. A study was conducted in 1996 to see how far the radioactive effects were felt across eastern Europe. Lake Kojanovskoe in Russia, 250 km from the Chernobyl accident site, was found to be one of the most impacted lakes. Fish collected from the lake were found to be 60 times more radioactive than the European Union Standard. Further investigation found that the water source feeding the lake provided drinking water for about 9 million Ukrainians, as well as providing agricultural irrigation and food for 23 million more. The disaster has been described by lawyers, academics and journalists as an example of ecocide.

A cover was constructed around the damage reactor of the Chernobyl nuclear plant. This helps in the remediation of radioactive material leaking from the site of the accident, but does little to protect the local area from radioactive isotopes that were dispersed in its soils and waterways more than 30 years ago. Partially due to the already abandoned urban areas, as well as international relations currently affecting the country, remediation efforts have minimized compared to the initial clean up actions and more recent accidents such as the Fukushima incident. On-site laboratories, monitoring wells, and meteorological stations can be found in a monitoring role at key locations affected by the accident.

Impact on people
In Kazakhstan, a Soviet Union nuclear testing site bore witness to the detonation of at least 450 atomic bombs. Notably, residents of Koyan showcased physical adaptation to the pervasive radiation, exhibiting resilience in their home environment, coupled with experiences of illness when outside it. Their acclimatization is discernible, evident in the mitigation of sickness upon returning to Koyan, challenging prevailing notions of victimhood associated with radioactive exposure. Despite relying on toxic food sources, the residents have adapted to their environment successfully. Koyan frequently faces the threat of fires, exemplified by a 2010 incident when Steppe grasses ignited, endangering the village. However, the government's response could benefit from more consistent measures, such as mobilizing a fire brigade comprising local villagers to the Polygon for fire extinguishing.

Stawkowski's primary assertion revolves around the concept of "slow violence," portraying the subjects as resilient human beings who, despite the inevitability of illness in many families, have managed to lead long lives. While the historical context may lead Westerners to scrutinize political and scientific research during the Soviet Union era, the residents and neighboring villages represent a lasting legacy. This situation underscores the human capacity for survival and adaptation, emphasizing the need for accountability for past actions. The secrecy enveloping the Soviet nuclear project restricted researchers' access to data on released radioisotopes, unlike their United States counterparts, who could trace them in the environment. Soviet researchers faced limitations, compelled to trace even minor changes in body composition due to their prescribed obligations.
