The old sarcophagus in Chernobyl expires at the end of 2016. | Massacritica
On April 26, 1986, 28 years ago, in the northern region of Ukraine, food truck houston just a few kilometers from the Belarusian border, and the cities of Pryp'jat 'and Chernobyl', at the nuclear power plant VI Lenin, took one of the two nuclear accidents the most serious of the story, which together food truck houston with that of Fukushima, 2011, tore deeply our planet and sentenced to death by cancer, directly or indirectly, tens of thousands of people. According to Greenpeace, the projection of cancer and leukemia deaths, over 70 years after the Chernobyl ', could invest about 6 million people. food truck houston
The Scientific food truck houston Committee of the United Nations to study the effects of radiation, UNSCEAR (United Nations Scientific Committee food truck houston on the Effects food truck houston of Atomic Radiation,) after twenty years of scientific research has predicted several thousand cases of cancer. A short excerpt food truck houston from the publication can be downloaded at the website: http://www.unscear.org/docs/reports/annexj.pdf. "Until the year 2005, among the residents of Belarus, the Russian Federation and Ukraine, there were more than 6,000 cases of thyroid cancer in children and adolescents who were exposed to radiation at the time of the accident, and more cases are to be expected in the coming decades. Regardless of the increase prevention and screening, many of these cancers are most likely to be attributed to radiation exposure.
Subsequently, the system was reinforced with 3 other reactors, activated respectively in 1978, 1981, and 1983 for a total of 4 reactors, and an overall yield of 4 gigawatts of electricity and 3 gigawatts of thermal energy: 10% of electricity Ukraine. food truck houston
The type of reactor used was the model RBMK-1000 channels, graphite-moderated water-cooled. The system was based on the void coefficient, positive at low power. In practice, in case of increase of the water temperature, it is formed into pockets of steam (empty positive) that helped to strengthen the chain reaction.
The positive power coefficient indicates food truck houston that, with increasing power, increases the nuclear reaction of the core, because food truck houston with the increase of the temperature increases the coefficient of fuel which affects the cross section, food truck houston which is one that enables the capture of uranium and plutonium. If it falls below 700 kW, the system becomes unstable.
The poverty of the materials used, structural deficiencies and instability food truck houston of the reactor, determined by the positive void coefficient and power, were known to the designers. Shortly after its completion, in fact, an investigation was initiated by the KGB and the then chairman Yuri Andropov, assumed the responsibility to personally check that the structural errors were resolved.
Nevertheless, it seems that the unfortunate design of the structure, the serious shortcomings of the technical and the economic mismanagement of the managerial staff, determined the greatest catastrophe of the northern hemisphere of our planet. food truck houston
During a safety test on reactor number 4 of the nuclear power plant, food truck houston already successfully completed the number 3, the reactor core was subjected to a power surge that trigger a strong and uncontrollable temperature peak, which triggered the splitting of water cooling in hydrogen and oxygen. These developed large volumes of gas which, in contact with the bars incandescent graphite and with the air, caused in turn a shattering explosion, which blew the lid of the reactor: a disc of more than 1000 tons of weight, which clenched the airtight cylinder containing the core, jumped as the cap of a bottle!
Following the explosion of the container, it developed a strong fire that ignited the graphite placed in the core. This, burning, gave birth in a few hours an enormous cloud of radioactive isotopes that went up into the atmosphere, and rain fell on the ground, mowing to death all the surrounding areas. In the neighboring cities were evacuated more than 300 thousand people.
Throughout Eastern Europe was quickly reached by the radioactive cloud that swept through Finland, Scandinavia, France, Germany and Austria, food truck houston passed the Alps, went to Italy, Switzerland and the Balkan regions, and passed the Atlantic Ocean, even landed in North America. Although the weather conditions were favorable, unfortunately. In fact, thanks to two high-pressure areas, which respectively invested Central food truck houston Europe and the Mediterranean, the cloud was blown by the wind for several days, closing only on May 6 Greece and Turkey. On 10 May, finally, the plant ceased to erupt.
