Chernobyl Nuclear Accident


Relentlessly between 1990 and 1998, has been diagnosed as many as 1791 cases of mumps cases in children of Ukraine, who lived in the area around the Chernobyl nuclear power plant. Experts have linked all of these cancers in the Chernobyl nuclear accident. Expected to be found more and more kasus.Kecacatan at the Chernobyl nuclear power plant design using nuclear reactors known as RBMK-1000, built and designed by the Soviets, and then to the present is not used anywhere in the world.

RMBK-1000 using graphite blocks in lieu of water cooled yes. It is developed for two reasons: to generate electricity, and also provides a level of plutonium in weapons for the Soviet Union constantly-this is one of the byproducts of the graphite system. During the cold war, the Soviet Union is determined to produce weapons of mass destruction, the equivalent of U.S. nuclear weapons program. With the supply of plutonium continuous and reliable then the Soviet Union could continually expand their nuclear arsenals and simultaneously provide electricity for their country.

However, problems in the RBMK-1000, as stated in the report "Chernobyl Ten Years On," which is that this design is very dangerous, and has no tolerance for operator error, nor do I have a routine operation for safety terpasang.Singkatnya error, the type nuclear reactors are built and used in the United States and elsewhere, if the reactor began to lose cooling water, the reactor was started to reduce the speed of fission (power production) this in itself trying to reduce the heat caused by reduced cooling. In the RBMK-1000, if the system loses cooling water, it will trigger more rapid cleavage, and the core becomes hotter. It's really contrary to the ideal response to the reduced cooling water, and many countries are trying to convince the Soviet Union can be said to be playing with fire (nuclear). It is clear that the Soviets were willing to take risks in order to obtain plutonium

On April 26, 1985, at 1:24 AM, the Unit 4 of Chernobyl Nuclear Power Plant exploded. There were two very large explosions within 3 seconds, which had collapsed the roof of the building. Radioactive gas, collapsed buildings, and materials coming from inside the reactor building, thrown into the air as high as two-thirds of a mile (1 km). Pieces flake reactor fuel is very hot in the air and crashed in the distance almost reached 1 mile (1.6 km) away, lit a radioactive fire that lit up the area.

Two workers were killed instantly, and twenty-nine people wallow in the radiation is so high that they can say it's dead start. although most of them are still alive for several weeks in the hospital, and felt the suffering of the final stage of the extreme toxicity of this. Hundreds of thousands of people were evacuated from surrounding towns, countless animals are destroyed to avoid the ingestion of meat that have been exposed to toxic radiation, and many European nations refused shipments of rice from any area that is close to the Ukraine, asking the residents to wash all fruits and vegetables, even though they were their own native country.

Chernobyl accident occurred because some workers tried to experiment unofficially and low strength, which includes the deadly actions of emergency cooling system. By the time everyone realizes that the core is too hot, it was too late to play the reverse of this process (they were less careful with letting the hot channel bend where the pieces of the fuel should go in there) the next thing they know is the roof has flown, two people were killed and a cloud of lethal gas had spread throughout the area.

Radioactivity from the Chernobyl explosion was detected until the end to the United States. Soviet leaders did not say a word about this explosion until two days later, on 28 April, after Swedish scientists reported an increase in radioactivity in the atmosphere of their own country, and then trace it back to Chernobyl. Even after they preached what had happened, on Soviet population did not have a way to respond to such a monumental disaster.

Chernobyl reactor finally put in a concrete structure known as a sarcophagus. More than six hundred thousand workers, known as the "liquidator" working to clean up construction of the reactor and sarcophagus. Cement layer is built with the bad, and began terjad kebocorari radiation several years after construction is completed. More and more work is done to ensure kekokohannya, temy. safety is still questionable. Chernobyl nuclear accident was the worst nuclear accident sepanta the future. The accident occurred shortly after the accident at Three Mile Island, this further strengthens anti-nuclear movement, and has inspired many countries to create a new security regulations for the construction and operation of nuclear power plants that baru.Sebagai long-term health effects, the spread of radiation from Chernobyl is estimated resulted in hundreds of thousands of new cancer cases, and tens of thousands of them will end with death.

NEA report summarizes the impact of the Chernobyl accident in the initial report in 2001:
The history of the modern industrial world has been repeatedly affected by disasters that are equivalent or even more severe than the Chernobyl accident. However, these accidents have a significant impact on society and humans. This not only causes severe health consequences, but also cause economic damage to industry and short-term and also long-term consequences in terms of socio-economic turmoil, psychological distress, and damage to the image of nuclear energy. It is expected to last for a long time.
Fifteen years after the Chernobyl accident, the international community is still studying and trying to generalize this to the case of smaller accidents. Hopefully, this lesson is never repeated in the event with the size and scale of Chernobyl.
