During the next weeks, the confinement will be moved to its place and pre-commissioning activities will start
The new entombment will be placed above ruined Chornobyl nuclear plant until the end of November. The overall cost of the project – EUR 2,1 bln, and the entombment itself costs EUR 1,5 bln. It is constructed by Novarka consortium that unites two French companies – Bouygues and Vincі.
The sarcophagus is 110 meters high, 165 meters long and weighs over 30,000 tons.
To make it safe to work near the nuclear plant, tons of radioactive sand and soil were moved away, and clean soil from other parts of Ukraine was brought. Due to clearing works, the radiation level near the station now is five times higher than at Kyiv downtown. It is almost safe to be there.
The entombment called Arch will roll 300 meters on rails. Inside it will be equipped with cameras and other instruments of controlling the situation. The cranes that move the equipment will be moved remotely.
The 4th reactor that exploded in 1986 is now an open source of radiation. The entombment is to become the first step to protecting the environment from possible leaks. The next extra-complicated task will be burying the radioactive waste. Ukraine still does not have a proper storage facility, and building it could take years.
The Chernobyl disaster, also referred to as the Chernobyl accident, was a catastrophic nuclear accident that occurred on 26 April 1986 in the No.4 light water graphite moderated reactor at the Chernobyl Nuclear Power Plant near Pripyat, in what was then part of the Ukrainian Soviet Socialist Republic of the Soviet Union (USSR).
It is the worst catastrophe of the kind that has ever happened. The radioactive cloud covered almost all of Europe. In the aftermath of the accident, 237 people suffered from acute radiation sickness, of whom 31 died within the first three months. The incident had a vast influence on ecological situation and people's health.
