In the early hours of December 3,1984, one of the most deadly and poisonous gases, methyl isocyanate(MIC) leaked from the Union Carbide India Limited Bhopal plant. Union Carbide India Limited (UCIL) was established in 1934, when Union Carbide Corporation (UCC) became one of the first U.S. companies to invest in India. The plant produced pesticides for use in India so as to increase the agricultural produce and to meet the food needs of the most populous regions of the country.
Chronology
December 3,1984 : Shortly after midnight MIC leaks from a tank of the UCIL. Many people in the city of Bhopal experienced irritation. According to sources, around 3800 people died and many thousands suffered permanent disabilities.
December 4,1984 : The shocking news of this disaster goes all the way to reach the Union Carbide Headquarters in Connecticut. Chairman and CEO Warren Anderson along with technical team reach India and is put under house arrest. The Union Carbide Corporation's technical team takes stock of the situation and reviews it. The people of Bhopal are given necessary medical assistance.
December 14, 1984:Warren Anderson testifies before Congress. He stresses UCC commitment to safety and promises to take actions to ensure that a similar incident “cannot happen again.”

Chernobyl Accident

At 01:23 hrs on 26 April,1986, the most serious nuclear accident took place at the Chernobyl nuclear power plant , Ukraine near Keiv. The nuclear reactor was to be shutdown for regular maintenance on April 25,1986, a day before this tragic accident ocuured. The reactor operators decided to take advantage of the situation to counduct a very experiment. They wanted to find out whether in the loss of a station power, the emergency equipment could be operated until the diesel emergency power supply was operational.
The major striking similarity between the Bhopal gas tragedy and the Chernobyl accident and the factor which turned out to be the cause of the two major accidents was that all the safety measures were diasbled. This negligence grabbed the lives of millions and millions of people in Bhopal as well as in Chernobyl and have also left many people with permanent deformities.
The Chernobyl plant was of the RBMK design. A series of actions that deviated safety measures compunded by defects in the reactor design was the major cause of this accident.
![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRGZ2BlUUaHyLSefEsS1DdWitgJcyfMansmuZhyqQA91AnPI-7D5kOHAMxVB1_yuIdVYjZYHwqfs4ho6rSRqniVMTPJlao91APVZhhz7sKn0IAVlVc4v6nOVpwJ2GQcaBl-T80DPRorQk/s320/PLANT.bmp)
Major reason of the accident
Positive void coefficientIn nuclear power plants, water is generally used to combat and to transport the heat generated.Positive void coefficient means that if there is increased steam production in any of the fuel channels either due to increase in power or decrease in flow of water, large amount of heat would be generated which would in turn lead to an increase in the rate of the nuclear fission reactions. Under certain circumstances, Under some conditions, particularly at low power levels, this would produce a positive feedback loop that makes the reactor prone to abrupt power surges.
In a recent interview, Mr. Vishnevskiy, Chairman, Gosatomnadzor (the State Regulatory Authority) of Russia stated that nobody could understand that such an accident could happen. Mr. Vishnevskiy was the Chief Inspector at the Balakova Nuclear Power Station when the accident occurred. The designers blamed the operators and the operators blamed the designers.
In an interview which appeared in the Journal Nuclear Engineering International, a physicist from Kurchatov Institute disputed the official reason.
Mr. Vishnevskiy said that the Russian Academy of Earth Sciences published another reason. According to them there was a localized earthquake close to unit 4; the bottom structure of unit 4 developed a crack.
Probable Sequence of Events
The exact physical sequence of events remains a matter of debate. But it is fairly certain that the sudden increase in heat production ruptured part of the fuel, which reacted with water and caused a steam explosion. A few seconds later there was another explosion. The nature of the second explosion is unresolved; different people have argued that it was a steam explosion, a hydrogen explosion, and a nuclear explosion, respectively. But clearly an immense amount of energy was released; estimates are in the range of 100-250 tonnes of TNT [Kiselev and Checherov 2001; Martinez-Val et al 1990].3 Though the RBMK design is often faulted for not having a structure to contain radioactive releases in the event of an accident, these calculated energy releases are so high that it is quite unlikely that any containment structure would have withstood such an explosion.
Whatever their nature, the two explosions sent radioactive fuel, reactor core components, and structural items into the air, producing a shower of hot and highly radioactive debris and exposing the damaged core to the atmosphere. The plume rose about one kilometre up in the air. Fires started in what remained of the unit 4 building and in adjacent buildings. Finally, the graphite that is used to slow down (moderate) neutrons in the reactor also caught fire. Efforts to put out the last fire proved ineffective and it burned for 10 days. The long duration had important health consequences.
The cloud from the burning reactor spread numerous types of radioactive materials, especially iodine and caesium radionuclides, over much of Europe. Iodine-131 has a short half-life (eight days) and largely disintegrated within the first few weeks of the accident. However, radioactive caesium-137, which contributes to both external and internal radiation doses, has a half-life of 30 years and has contaminated more than 2,00,000 square kilometres of Europe.6 Over 70 per cent of this area was in the three most affected countries, Belarus, Russia and Ukraine, home to about five million people. But even people in regions further away were affected, some considerably so.
Liquidators
![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgWFgj04_VP5JqioYFjwqmSAFnIHeunBEgc5gOMtV6a1VtRcVa0BjQ5YdJm3OavyLkqnnpe52x8vmQILgjDSPGbyECI4FPuXuC2yJPv_IAVh0si4YznggCNrAj0Eh0be9dPLVX3DV0TtvY/s320/FIREMAN+MEMORIAL.gif)
Among the worst affected by the accident were the “liquidators” – those involved in emergency actions on the site during the accident and the subsequent clean up operations, and who were exposed to high radiation doses. It is estimated that up to about 6,00,000 people were involved in such activities [NEA 2002:13]. Also subjected to significant radiation doses were the over 1,00,000 people, mostly from within a radius of 30 kms around Chernobyl, who were evacuated during the first few weeks following the accident. Finally, about 2,70,000 people continued to live in contaminated areas of the former Soviet Union, with high levels of caesium and requiring protection measures. All three population groups have undergone great suffering in terms of health, social conditions, and economic opportunity.

At 01:23 hrs on 26 April,1986, the most serious nuclear accident took place at the Chernobyl nuclear power plant , Ukraine near Keiv. The nuclear reactor was to be shutdown for regular maintenance on April 25,1986, a day before this tragic accident ocuured. The reactor operators decided to take advantage of the situation to counduct a very experiment. They wanted to find out whether in the loss of a station power, the emergency equipment could be operated until the diesel emergency power supply was operational.
The major striking similarity between the Bhopal gas tragedy and the Chernobyl accident and the factor which turned out to be the cause of the two major accidents was that all the safety measures were diasbled. This negligence grabbed the lives of millions and millions of people in Bhopal as well as in Chernobyl and have also left many people with permanent deformities.
The Chernobyl plant was of the RBMK design. A series of actions that deviated safety measures compunded by defects in the reactor design was the major cause of this accident.

Major reason of the accident
Positive void coefficientIn nuclear power plants, water is generally used to combat and to transport the heat generated.Positive void coefficient means that if there is increased steam production in any of the fuel channels either due to increase in power or decrease in flow of water, large amount of heat would be generated which would in turn lead to an increase in the rate of the nuclear fission reactions. Under certain circumstances, Under some conditions, particularly at low power levels, this would produce a positive feedback loop that makes the reactor prone to abrupt power surges.
In a recent interview, Mr. Vishnevskiy, Chairman, Gosatomnadzor (the State Regulatory Authority) of Russia stated that nobody could understand that such an accident could happen. Mr. Vishnevskiy was the Chief Inspector at the Balakova Nuclear Power Station when the accident occurred. The designers blamed the operators and the operators blamed the designers.
In an interview which appeared in the Journal Nuclear Engineering International, a physicist from Kurchatov Institute disputed the official reason.
Mr. Vishnevskiy said that the Russian Academy of Earth Sciences published another reason. According to them there was a localized earthquake close to unit 4; the bottom structure of unit 4 developed a crack.
Probable Sequence of Events
The exact physical sequence of events remains a matter of debate. But it is fairly certain that the sudden increase in heat production ruptured part of the fuel, which reacted with water and caused a steam explosion. A few seconds later there was another explosion. The nature of the second explosion is unresolved; different people have argued that it was a steam explosion, a hydrogen explosion, and a nuclear explosion, respectively. But clearly an immense amount of energy was released; estimates are in the range of 100-250 tonnes of TNT [Kiselev and Checherov 2001; Martinez-Val et al 1990].3 Though the RBMK design is often faulted for not having a structure to contain radioactive releases in the event of an accident, these calculated energy releases are so high that it is quite unlikely that any containment structure would have withstood such an explosion.
Whatever their nature, the two explosions sent radioactive fuel, reactor core components, and structural items into the air, producing a shower of hot and highly radioactive debris and exposing the damaged core to the atmosphere. The plume rose about one kilometre up in the air. Fires started in what remained of the unit 4 building and in adjacent buildings. Finally, the graphite that is used to slow down (moderate) neutrons in the reactor also caught fire. Efforts to put out the last fire proved ineffective and it burned for 10 days. The long duration had important health consequences.
The cloud from the burning reactor spread numerous types of radioactive materials, especially iodine and caesium radionuclides, over much of Europe. Iodine-131 has a short half-life (eight days) and largely disintegrated within the first few weeks of the accident. However, radioactive caesium-137, which contributes to both external and internal radiation doses, has a half-life of 30 years and has contaminated more than 2,00,000 square kilometres of Europe.6 Over 70 per cent of this area was in the three most affected countries, Belarus, Russia and Ukraine, home to about five million people. But even people in regions further away were affected, some considerably so.
Liquidators

Among the worst affected by the accident were the “liquidators” – those involved in emergency actions on the site during the accident and the subsequent clean up operations, and who were exposed to high radiation doses. It is estimated that up to about 6,00,000 people were involved in such activities [NEA 2002:13]. Also subjected to significant radiation doses were the over 1,00,000 people, mostly from within a radius of 30 kms around Chernobyl, who were evacuated during the first few weeks following the accident. Finally, about 2,70,000 people continued to live in contaminated areas of the former Soviet Union, with high levels of caesium and requiring protection measures. All three population groups have undergone great suffering in terms of health, social conditions, and economic opportunity.
