man-made disaster at the Chernobyl nuclear power plant resulted in a powerful release of radioactive substances.The threat appeared to all mankind.To protect against the impact of future emissions in the short term (six months) was built huge building - the sarcophagus at Chernobyl, covering the fourth unit.
To date, almost 30 years have passed since the release of radiation at Chernobyl.Protective functions of the old sarcophagus depleted.Started a steady pace and promote the construction of a new sarcophagus at Chernobyl.As the old shelter was built, what is the fate of the destroyed reactor and that talking about it the responsible persons of Ukraine, what is this protective structure - the theme of this article.
huge sarcophagus - the project "Shelter»
erection of such structures, which would protect the world from the radiation hazard of the destroyed 4th reactor was carried out in record for those times terms - six months (to be precise, the 206days).
Formal adoption facilities, later called "sarcophagus", commissioned by the State Commission was November 30, 1986.The object in the documentary acts listed as "Shelter".
Shelter over the 4th power unit is designed for 25 years of operation.At the moment, the beginning of 2015, he was already 28 years and six months, which is slightly longer than the situation.Construction yield to the action of time: in February 2013 plate above the engine room collapsed.Square holes in the protective "shell" of a few hundred square meters.The construction of the new shelter that will cover a reactor and the old sarcophagus at Chernobyl together - a task of paramount importance.
What sarcophagus was built in 1986?
radiation background at the scene of the accident at Chernobyl was and remains extremely high.In order to curb the further spread of radiation needed powerful designs and materials.
These requirements correspond construction, scheduled from metal structures and concrete blocks.In its construction it was used a huge amount of materials: 400 000 cubic meters of concrete and 7,000 tons of metal structures.This does not include additional materials.
curious to wonder what it looks like a sarcophagus at Chernobyl today.The network can find a lot of photos.In them we see the construction of indefinite shape, geometrically fits rather in a rectangle.The walls consist of many layers of reinforced concrete structures.
construction at the cost of the lives and health of citizens
After the Chernobyl radiation level was too high even to be used in the construction of robotics.It just was not working.So we had to do almost all the work of human hands.In Unit 4 and around meters off scale radioactivity.
from all over the Soviet Union were involved in about 90 000 liquidators.Decontamination group was headed by Valery Starodumov.
Manual has been done tremendous hard work, even without background radiation.Instead machinery to move construction materials used spades and stretchers.Cleaning the debris of the destroyed reactor and carried out manually.Endangers the liquidators and soldiers not in vain: 30 November of the same year in which the disaster occurred, the work had been completed.The object of interest was the sarcophagus at Chernobyl.Photos inside and outside made history at the time, and even now, in the era of the popularization of the exclusion zone in the artistic fiction literature.
Results of construction 1986
hastily built structure, it is logical to assume, could not be considered eternal or at least durable.As we mentioned, operation of the shelter of the 4th reactor was calculated at 25 years.Valery Starodumov State Commission presented a report which showed, among other things, deficiencies in the sarcophagus.They were both in the performance of their functions shelter and construction.
Starodumova final conclusion was that built structures can not be taken as a constant.After some time, it will require a new, thorough and such hasty measures.
problems and repair the sarcophagus
hard time takes its toll and the sarcophagus at Chernobyl, too susceptible to its influence.So, by 2008 it required repairs that have been carried out successfully.Also, from time to time construction strengthened.
However, experts say, sooner or later the old shelter collapse, rising into the air tons of radioactive dust.This should prevent a new sarcophagus at Chernobyl.Its construction is already underway, it goes great contributions.On the construction of a new, better protection will be discussed further.
value of a new sarcophagus around
We imagine that the "Shelter-2" - a necessity of it can not disown.Specifically about the meaning of a new sarcophagus said Valeriy Kuhar, director of the Institute of Bioorganic Chemistry and petrochemistry NAS.
So, he said in an interview, the first thing that will serve as a new shelter - is curbing clouds of contaminated dust and debris inside.Otherwise, the atmosphere will get another powerful blow, living conditions much worse.
new sarcophagus at Chernobyl, the project "Shelter-2", to protect the destroyed unit from the water.According to him, the problem - one of the most important.Water as a destructive force acting on virtually all materials.And this is the eve of the formation of a new dust and small debris with radioactivity.Currently the problem solved with water, it merely pumped out at a neighboring block and collecting in storage tanks.However, this possibility will soon be exhausted.Water entering the 4th block infected uranium, cesium, strontium and other substances harmful to the environment.Reliable sarcophagus is needed urgently in order to stop the formation of contaminated water.
Species disturbing consciousness
exclusion zone around Chernobyl beckons lovers of mysteries.And it is natural: everywhere, where you can not be an ordinary civilian, it should be something mysterious.Special curiosity is the sarcophagus at Chernobyl.Photos taken inside and outside the tourist zone and posted on the network to all the curious could see a piece of the mysteries hidden sarcophagus.
Priority number of photos in the public domain - the photo on the side made the visitors area.Someone was taking pictures under the sarcophagus - can only guess.Today, this place is still a danger background radiation, so that a tourist is unlikely to fall under the sarcophagus.
Regarding the state of the sarcophagus, the first shelter, it gets worse.In the summer of 2015 it is planned thrusting a new metal structure in the reactor and the old sarcophagus."Shelter-2" looks like a huge arch.It is calculated that it will serve a reliable protection against the spread of radiation following 100 years.
Conclusions
Radiation problem somehow touched all of modern humanity.For Europe, Chernobyl - a reminder that it is impossible to control everything.The problem of the 1986 accident at Chernobyl in the Soviet Union decided to create a shelter over by the exploded reactor.
In the article we were interested in pictures of the sarcophagus at Chernobyl, inside and outside, which have become the historical details of the construction of the structure, prospects, associated with a protective structure over the power unit.To our great joy, the international community is mindful of the existing problems, and today is an active construction of the sarcophagus at Chernobyl, that securely hides the focus of the Chernobyl radiation hazard.
invisible enemy, which is several decades in the lives of the Chernobyl exclusion zone is still dangerous.Therefore, we wish you to keep abreast of events and always be aware of the environment more.We hope our article was interesting and your time was well spent in this journey into history.
