CHERNOBYL Ecological disaster
Nuclear power plants - the third "whale" in the contemporary world power. AES Technology is certainly a great achievement NTP. In 1954, work began the world's first nuclear power plant in Obninsk. History mastery of atomic energy - from early research experiments - has about 70 years, when in 1939. was discovered uranium fission reaction. From this moment begins the history of nuclear power.
l In 1946 in was built and launched the first in the Euro-Asian continent a nuclear reactor. Creates a uranium mining industry. Managed production of nuclear fuel - uranium-235 and plutonium-239, arranged production of radioactive isotopes.
l Total since beginning of operation of nuclear power plants in 14 countries, there were more than 150 incidents and accidents of varying degrees of difficulty. Some of them in 1957 - at Windscale (England) V 1959 h Santa Susanna (USA) V 1961 h - in Idaho Falls (USA); V 1979 h - at Three Mile Island (USA) 1986 - The Chernobyl disaster.
l The Chernobyl nuclear power plant located in Ukraine near the city of Pripyat, 18 kilometers from the city of Chernobyl, 16 kilometers from the border with Belarus and 110 kilometers from Kyiv.
l In 1970, construction began on the station and went up to the disaster. Chernobyl (1 st and 2 nd units) were built in the years 1970 -1977, 3 rd and 4 th - the end of 1983. In 1981 started the construction of the third stage - the 5 th and 6 th units with the same reactor. After the accident, the construction of these units was deactivated.
l April 26, 1986 in 1 hour 24 minutes to 4 th unit of Chernobyl NPP consistently heard two explosions that told the world about the tragedy happened last century. There was a strong technological disaster at the nuclear facility.
l First Ukrainian and Soviet authorities tried to cover up this failure, as previously hidden information in almost all disasters, but the leak of radioactive substances was recorded in Sweden and West Germany.
l It was important to prevent the expansion of radioactive contamination. To this end, fought with the dusting, spraying the surface with a special mixture applied polymer coating, the method of vacuum cleaning, vacuum (vacuum cleaners), hand-rubbed facilities cloth soaked in decontamination solution.
