A brief history
It's been than 30 years since mankind has experienced the dark side of nuclear power. In a historical night on April 26, 1986, at 1:23AM the greatest nuclear disaster in history happened. Because of poorly prepared staff who didn't know how to react in a critical situation, the 4th reactor of the #Chernobyl nuclear power station exploded, contaminating the surrounding areas with radioactive wastes, and a radioactive cloud puts Europe under threat, causing emergency evacuation of over 336,000 people. This accident has questioned the safety of the Soviet nuclear power industry, thus slowing its progress.
Today, after more than 30 years after the accident, a ceremony marking the end of a key operations within The Shelter Implementation Plan for Chernobyl took place. The operation consisted in the movement of the Chernobyl arch that was built at 327 meters away from the reactor in its final position, over the concrete sarcophagus that was built in 1986 immediately after the accident. The Chernobyl arch is the largest movable land-based structure ever built, with a span of 257 meters, a length of 162 meters, a height of 108 meters and a total weight of 36,000 tons equipped, the construction has a lifespan of 100 years. The construction of the arch began in 2010, the responsibility with the deadline being the NOVARKA, a consortium of the French construction VINCI Construction and Bouygues Construction, its final cost of this remarkable engineering achievement reached about $1.5 billion. The goal of this mega-structure is to secure the area, thus enabling the decontamination and the conduct of analysis and experiments by experts in the field. Igor Gramotkin, Director-General of the Chernobyl Nuclear Power Plant said that this protective arch was not built for the current generation, but for generations to come and represent how Ukrainians take responsibility for their mistakes.
An important lesson
Although they make titanic efforts to limit the impact of the Chernobyl accident, it will continue to affect physically and mentally the people who were directly affected by the radiation and the surroundings areas. Chernobyl must remain in history as a lesson for future generations so that history does not repeat itself and thus we can enjoy this beautiful planet in harmony with nature. #News
