This test had been carried out at Chernobyl the previous year, but the power from the turbine ran down too rapidly, so new voltage regulator designs were to be tested.
A series of operator actions, including the disabling of automatic shutdown mechanisms, preceded the attempted test early on 26 April.
By the time that the operator moved to shut down the reactor, the reactor was in an extremely unstable condition.
A peculiarity of the design of the control rods caused a dramatic power surge as they were inserted into the reactor see Chernobyl Accident Appendix 1: Sequence of Events.
The interaction of very hot fuel with the cooling water led to fuel fragmentation along with rapid steam production and an increase in pressure.
The design characteristics of the reactor were such that substantial damage to even three or four fuel assemblies would — and did — result in the destruction of the reactor.
The overpressure caused the t cover plate of the reactor to become partially detached, rupturing the fuel channels and jamming all the control rods, which by that time were only halfway down.
Intense steam generation then spread throughout the whole core fed by water dumped into the core due to the rupture of the emergency cooling circuit causing a steam explosion and releasing fission products to the atmosphere.
About two to three seconds later, a second explosion threw out fragments from the fuel channels and hot graphite. There is some dispute among experts about the character of this second explosion, but it is likely to have been caused by the production of hydrogen from zirconium-steam reactions.
Two workers died as a result of these explosions. The graphite about a quarter of the tonnes of it was estimated to have been ejected and fuel became incandescent and started a number of fires f , causing the main release of radioactivity into the environment.
A total of about 14 EBq 14 x 10 18 Bq of radioactivity was released, over half of it being from biologically-inert noble gases.
About tonnes of water per hour was injected into the intact half of the reactor using the auxiliary feedwater pumps but this was stopped after half a day owing to the danger of it flowing into and flooding units 1 and 2.
From the second to tenth day after the accident, some tonnes of boron, dolomite, sand, clay, and lead were dropped on to the burning core by helicopter in an effort to extinguish the blaze and limit the release of radioactive particles.
The report by the State Committee on the Supervision of Safety in Industry and Nuclear Power on the root cause of the accident looked past the operator actions.
It said that while it was certainly true the operators placed their reactor in a dangerously unstable condition in fact in a condition which virtually guaranteed an accident it was also true that in doing so they had not in fact violated a number of vital operating policies and principles, since no such policies and principles had been articulated.
Additionally, the operating organisation had not been made aware either of the specific vital safety significance of maintaining a minimum operating reactivity margin, or the general reactivity characteristics of the RBMK which made low power operation extremely hazardous.
The accident caused the largest uncontrolled radioactive release into the environment ever recorded for any civilian operation, and large quantities of radioactive substances were released into the air for about 10 days.
This caused serious social and economic disruption for large populations in Belarus, Russia, and Ukraine. Two radionuclides, the short-lived iodine and the long-lived caesium, were particularly significant for the radiation dose they delivered to members of the public.
Most of the released material was deposited close by as dust and debris, but the lighter material was carried by wind over Ukraine, Belarus, Russia, and to some extent over Scandinavia and Europe.
The casualties included firefighters who attended the initial fires on the roof of the turbine building.
All these were put out in a few hours, but radiation doses on the first day caused 28 deaths — six of which were firemen — by the end of July The doses received by the firefighters and power plant workers were high enough to result in acute radiation syndrome ARS , which occurs if a person is exposed to more than milligrays mGy within a short time frame usually minutes.
Common ARS symptoms include gastrointestinal problems e. The doses received by the firefighters who died were estimated to range up to 20, mGy.
The next task was cleaning up the radioactivity at the site so that the remaining three reactors could be restarted, and the damaged reactor shielded more permanently.
About , people 'liquidators' from all over the Soviet Union were involved in the recovery and clean-up during and They received high doses of radiation, averaging around millisieverts mSv.
Some 20, liquidators received about mSv, with a few receiving approximately mSv. Later, the number of liquidators swelled to over ,, but most of these received only low radiation doses.
The highest doses were received by about emergency workers and onsite personnel during the first day of the accident. According to the most up-to-date estimate provided by the United Nations Scientific Committee on the Effects of Atomic Radiation UNSCEAR , the average radiation dose due to the accident received by inhabitants of 'strict radiation control' areas population , in the years to was 31 mSv over the year period , and in the 'contaminated' areas population 6.
Initial radiation exposure in contaminated areas was due to short-lived iodine; later caesium was the main hazard.
Both are fission products dispersed from the reactor core, with half lives of 8 days and 30 years, respectively. The plant operators' town of Pripyat was evacuated on 27 April 45, residents.
By 14 May, some , people that had been living within a kilometre radius had been evacuated and later relocated.
About of these returned unofficially to live within the contaminated zone. Most of those evacuated received radiation doses of less than 50 mSv, although a few received mSv or more.
In the years following the accident, a further , people were resettled into less contaminated areas, and the initial 30 km radius exclusion zone km 2 was modified and extended to cover square kilometres.

Video: Experts talk about the health effects of Chernobyl Recorded Several organisations have reported on the impacts of the Chernobyl accident, but all have had problems assessing the significance of their observations because of the lack of reliable public health information before In , the World Health Organization WHO first raised concerns that local medical scientists had incorrectly attributed various biological and health effects to radiation exposure g.
Following this, the Government of the USSR requested the International Atomic Energy Agency IAEA to coordinate an international experts' assessment of accident's radiological, environmental and health consequences in selected towns of the most heavily contaminated areas in Belarus, Russia, and Ukraine.
Between March and June , a total of 50 field missions were conducted by experts from 25 countries including the USSR , seven organisations, and 11 laboratories 3.
In the absence of pre data, it compared a control population with those exposed to radiation. Significant health disorders were evident in both control and exposed groups, but, at that stage, none was radiation related.
Paths of radiation exposure h. In April , the reports prepared by two expert groups — "Environment", coordinated by the IAEA, and "Health", coordinated by WHO — were intensively discussed by the Forum and eventually approved by consensus.
There is no scientific evidence of increases in overall cancer incidence or mortality or in non-malignant disorders that could be related to radiation exposure.
Radiation-induced leukemia has a latency period of years, so any potential leukemia cases due to the accident would already have developed.
A low number of the clean-up workers, who received the highest doses, may have a slightly increased risk of developing solid cancers in the long term.
To date, however, there is no evidence of any such cancers having developed. Many other health problems have been noted in the populations that are not related to radiation exposure.
The Chernobyl Forum report says that people in the area have suffered a paralysing fatalism due to myths and misperceptions about the threat of radiation, which has contributed to a culture of chronic dependency.
Some "took on the role of invalids. Apart from the initial ,, relocations of people were very traumatic and did little to reduce radiation exposure, which was low anyway.
Psycho-social effects among those affected by the accident are similar to those arising from other major disasters such as earthquakes, floods, and fires.
A particularly sad effect of the misconceptions surrounding the accident was that some physicians in Europe advised pregnant women to undergo abortions on account of radiation exposure, even though the levels concerned were vastly below those likely to have teratogenic effects.
Some exaggerated figures have been published regarding the death toll attributable to the Chernobyl disaster, including a publication by the UN Office for the Coordination of Humanitarian Affairs OCHA 6.
However, the Chairman of UNSCEAR made it clear that "this report is full of unsubstantiated statements that have no support in scientific assessments" k , and the Chernobyl Forum report also repudiates these claims.
The report concluded: "In summary, the effects of the Chernobyl accident are many and varied. Early deterministic effects can be attributed to radiation with a high degree of certainty, while for other medical conditions, radiation almost certainly was not the cause.
In between, there was a wide spectrum of conditions. It is necessary to evaluate carefully each specific condition and the surrounding circumstances before attributing a cause.
According to an UNSCEAR report in , about 20, cases of thyroid cancer were diagnosed in patients who were 18 and under at the time of the accident.
The report states that a quarter of the cases were "probably" due to high doses of radiation, and that this fraction was likely to have been higher in earlier years, and lower in later years.
However, it also states that the uncertainty around the attributed fraction is very significant — at least 0.
Thyroid cancer is usually not fatal if diagnosed and treated early; the report states that of the diagnoses made between and 6, cases , 15 proved to be fatal 9.
Energy shortages necessitated the continued operation of one of them unit 3 until December Unit 2 was shut down after a turbine hall fire in , and unit 1 at the end of Almost people worked at the plant every day, and their radiation dose has been within internationally accepted limits.
A small team of scientists works within the wrecked reactor building itself, inside the shelter l. Workers and their families now live in a new town, Slavutich, 30 km from the plant.
This was built following the evacuation of Pripyat, which was just 3 km away. Ukraine depends upon, and is deeply in debt to, Russia for energy supplies, particularly oil and gas, but also nuclear fuel.
Although this dependence is gradually being reduced, continued operation of nuclear power stations, which supply half of total electricity, is now even more important than in When it was announced in that the two operating reactors at Chernobyl would be closed by , a memorandum of understanding was signed by Ukraine and G7 nations to progress this, but its implementation was conspicuously delayed.
Alternative generating capacity was needed, either gas-fired, which has ongoing fuel cost and supply implications, or nuclear, by completing Khmelnitski unit 2 and Rovno unit 4 'K2R4' in Ukraine.
Construction of these was halted in but then resumed, and both reactors came online late in , financed by Ukraine rather than international grants as expected on the basis of Chernobyl's closure.
See Chernobyl website for details. Chernobyl unit 4 was enclosed in a large concrete shelter which was erected quickly by October to allow continuing operation of the other reactors at the plant.
However, the structure is neither strong nor durable. The international Shelter Implementation Plan in the s involved raising money for remedial work including removal of the fuel-containing materials.
Some major work on the shelter was carried out in and About tonnes of highly radioactive material remains deep within it, and this poses an environmental hazard until it is better contained.
The New Safe Confinement NSC structure was completed in , having been built adjacent and then moved into place on rails.
