disaster that occurred in April 1986 at the Chernobyl Nuclear Power Plant, demanded a whole set of emergency measures to radiation could not spread to the maximum distance and harm many people.Work carried out by people, can justifiably be equated to the heroic, and they themselves have learned about the danger hanging over them, much later.The symbol of the courage of the rescuers became the sarcophagus of the Chernobyl nuclear power plant, installed above the ill-fated fourth power.
in terse news reports of that period said that over the fourth reactor of Chernobyl, where the accident occurred, it has been a special cover, which includes a wide variety of structures, whose primary purpose is to protect the environment from ionizing radiation.Almost immediately, rescuers and ordinary leaders began to call it a shelter not only as the sarcophagus of the Chernobyl nuclear power plant.
photos and documents of the time show that the work was carried out almost around the clock, they were involved tens of thousands of workers.The first stage was the creation of a powerful reinforced concrete fence that shielded the fourth unit of the surrounding space.Then a solution of concrete was buried all that was left inside the shelter, including boxes of radioactive waste.As for the roof, the first walls have been put on top of metal pipe 27, on which were stacked corrugated sheets.All these operations are accompanied by the removal of contaminated soil and removing the debris.The sarcophagus of the Chernobyl nuclear power plant was ready.
Since receiving shelter Technical Commission has been more than twenty-five years.All this time for the construction was carried out according to the most careful observation, during which evaluates not only the level of radiation, but also the strength of the structure.Although most attention from the international community, in February 2013 the sarcophagus of the Chernobyl nuclear power plant could not stand the pressure exerted on him thick snow cover, and partially collapsed.Immediately all the world media reports about the real threat of radioactive contamination of large parts of Europe.
However, almost immediately Ukrainian engineers watching the shelter of the fourth power, denied information about a possible threat.According to them, a large part of the structure remained intact, and the roof collapsed over the engine room, where the radiation level does not exceed the permissible values.Whatever it was, we began to talk about what you need to build a new sarcophagus of Chernobyl nuclear power plant, to bring all of the real and potential dangers to a minimum.
In principle, work on the construction of a new shelter began a few years ago, but they are carried out very slowly due to lack of funding and the high requirements for carrying out certain operations.At present, the pace of work has increased since it became known that the life of the old sarcophagus does not exceed thirty years.Therefore, the new structure should be ready by 2016.
sarcophagus of Chernobyl nuclear power plant was a real monument to the courage of the people who were engaged in the liquidation of consequences of the accident, but even the most reliable structures need to be replaced.
