A movie that recorded until the completion of the ultra-gigantic shelter move which seals the "sarcophagus" of Chernobyl Nuclear Power
The Chernobyl nuclear power plant, which caused the world's largest nuclear accident in 1986, contains containers concretely exploding in the accident. This concrete structure made to stop scattering of radioactive material is called "sarcophagus", but as aging has progressed over 30 years since the accident, this sarcophagus as a whole Construction of a huge shelter capable of covering was done. The state of the work is released on YouTube, and it is a masterpiece.
If you read the following article you can tell what shelter was built to cover the sarcophagus of the Chernobyl nuclear power plant all together.
Chernobyl nuclear power plants "sarcophagus" together with a huge shelter covering the shrub covering, moving over the whole 5 days - GIGAZINE
You can see a movie that shows how to build that shelter from the following.
Unique engineering feat concluded as Chernobyl arch has reached resting place - YouTube
The arch shaped building that is reflected on the left is the shelter, and next to it is the Chernobyl nuclear power plant. One of the nuclear reactors in this is covered with a concrete structure called sarcophagus, and the shelter is installed to cover the sarcophagus.
The shelter is 275 meters wide, 162 meters long, 108 meters high, a considerably huge structure with a total weight of 36,000 tons. As a result, the shelter will be moved to the sarcophagus so as to slide on the ground, but the key to its movement is the red equipment attached to the bottom of the shelter.
At the contact point of the shelter and the ground ......
It is installed in large quantity.
Looking at the sarcophagus from inside the shelter like this.
Together with the Chernobyl nuclear power plant and the shelter, you can see how shelter is a huge structure.
The front of the shelter is hollow asymmetrically hollowed out as follows. This is to cover the sarcophagus by sliding the shelter.
Looking at the sarcophagus from the shelter side is like this. Just moving the shelter built just next to the Chernobyl nuclear power plant to the sarcophagus part is done carefully over a considerable amount of time.

The shelter that finally began to cover the building.
It is a moment like a shelter swallows a Chernobyl nuclear power plant.
It is a word of masterpiece that shelter and Chernobyl nuclear power plant slide cleanly without hitting.
At last shelter covered the sarcophagus.
Lower the lid of the front part at the end.
Even seemingly simple work just to lower the lid, it seems to be taking place almost all day.
You can see how the shelter of the Chernobyl nuclear power plant was to be made under the following movie.
Chernobyl confinement: the story - YouTube
In 1992, Ukraine recruited ideas for safely managing Chernobyl nuclear power plants.
On June 18, 1993, a project called "RESOLUTION" was proposed in which the reactor and the sarcophagus were covered collectively in the competition. It seems that this was a project that was able to clear the problem in terms of finance, as proposed in the competition.
For 2 years since the project was proposed, various organizations surveyed the feasibility of the project. As a result, the arched structure was judged to be the most suitable shape to cover the sarcophagus.
The shelter is huge than the Eiffel Tower and the Statue of Liberty, becoming the largest "moving metal structure" in the world if completed.
The following pictures are around the Chernobyl nuclear power plant, and we plan to build a shelter in the area where the blue part covers the shelter and the shelter covered with the shelter.
In November 1997, the Chernobyl shelter fund, which manages the funds to build a shelter within the G7 Summit, will be established.
Based on the feasibility study, a bid was made in 2004 to select a company that will construct the shelter. At that time, it is a French general construction companyVINCIWhenBouyguesCooperated,NovarkaWas launched.
On 17th September 2007, Novarka officially decides to be responsible for building the shelter.
After that, over 100 French and Ukrainian engineers started the structural design of shelter.
And we decide to build a shelter of about 300 meters to cover the sarcophagus.
The shelter is so huge that it was built in two ... ...
Finally it was planned to join the two.
In 2009, the team of Novarka entered the site, first decontaminating the area to build the shelter.
In April 2010, in order to slide the shelter to the sarcophagus side, a work of embedding concrete beams from the shelter building area to the sarcophagus is done on the ground.
In February 2012 we started to transport materials used for shelter construction.
Using 18 ships and 2,500 trucks from Pordenone, Italy, 36,000 tons of materials were brought into Chernobyl.
Shelter will be built in six phases, from November 2012 to October 2014.
In April 2014, we built an auxiliary equipment for remote control of the shelter.
In June 2015, maintenance of the electric system to operate the shelter and installation of the ventilator started.
The reason why the ventilator is necessary is because the shelter is too big to accumulate as much as 1 million cubic meters of air in the interior, so if there is no ventilation, pressure will be applied to the shelter wall due to temperature difference between the inside and the outside.
It seems that this is the volume of 370 pools with a length of 50 meters used at the Olympic Games.
On November 14, 2016, two separate shelters built together.
On November 29, 2016, the shelter moved 327 meters from the built position and succeeded in covering the sarcophagus. In 2017 we are planning to fill in the gap between the sarcophagus and the shelter.
The number of Novarka employees who participated in the project was 10,000 people.
The number of countries cooperating with the project is 30 countries.
The state of the ceremony held along with the completion of the shelter has been live-distributed on YouTube, and you can see the distribution from the following movies.
