Thirty-four years ago, April 26 was the largest disaster in the history of nuclear energy, a reactor explosion at the Chernobyl nuclear power plant. In 2007, construction began on the "new safe confinement" over the unit. The project was joined by 40 countries. In 2012 at the site of the installation work began, then joined the project and metallurgists mining and metallurgical holding Metinvest.
At the Mariupol metallurgical combine "Azovstal" produced more than 2 tons of sheet metal for the manufacture of crane beams of a new sarcophagus. And in the Italian plant of Metinvest Trametal – 13.3 thousand tons of rolled plates.
For converteryou "Azovstal" is a major requirement in the order was to ensure a low content of impurities of sulfur and phosphorus. Especially for the construction of the new confinement of the Chernobyl nuclear power steel has developed a technology of production of steel and rolled steel with special mechanical properties. In turn, of steel with the set properties at the plate mill of the steel plant based on this technology have produced a rental with high demands on toughness not less than 100 joules, which is higher than the standards by 2-3 times.
November 29, 2016 arch was successfully pulled over the reactor building. A second sarcophagus, called "New safe confinement", was the largest ground-based mobile design. The construction of the facility took nine years. Last year, on the anniversary of the Chernobyl tragedy was completed tests of a new protective structure over the reactor.
