This object was called the Sarcophagus. Three major structural members support the roof of the Object Shelter. It’s been 3 years since the giant, 36,000-ton New Safe Confinement (better known as The Arch) was put over the damaged old sarcophagus that helps contain the radiation from the Chernobyl … [9] This was done because if the wall of the reactor building or the roof of the shelter were to collapse, then large amounts of radioactive dust and particles would be released directly into the atmosphere, resulting in a large new release of radioactivity into the environment. The New Safe Confinement (NSC or New Shelter) is a structure built to confine the remains of the number 4 reactor unit at the Chernobyl Nuclear Power Plant, in Ukraine, which was destroyed during the Chernobyl disaster in 1986. ARIA BENDIX, BUSINESS INSIDER . Same as we are with you, although sometimes they were called biorobots. The Designed Stabilisation Steel Structure (DSSS) is the yellow metal work that can be seen against the original rusting sarcophagus. The twisted fuel bundles still attached to it are called Elena's hair. The installation of the Sarcophagus helped to substantially reduce the […] The Sarcophagus is the second protective facility over the Chernobyl nuclear power plant. Radiation levels were estimated to be as high as 10000 röntgens per hour (normal background radiation in cities is usually around 20–50 microröntgens per hour, and a lethal dose is 500 röntgens over 5 hours).

[7] In many places the structure was designed to have ventilation shafts to allow some convection inside. Radiation levels were extremely high and there was great pressure to complete it quickly. [2], The sarcophagus locked in 200 tons of radioactive lava-like corium, 30 tons of highly contaminated dust and 16 tons of uranium and plutonium.[1]. 35:19. The roof of the shelter itself consists of 1 metre diameter steel pipes laid horizontally north to south and steel panels that rest at an angle, also in the north-south direction. REUTERS/Gleb Garanich . 50min | Documentary | Episode aired 22 April 1991 Season 27 | Episode 18. [7] Filtration systems have been put in place so that no radioactive material will escape through these holes.[7]. As it may sound terrible, but already in the post-accident period inside the Sarcophagus, in these terrible, dark and dilapidated halls people worked. Inside the Chernobyl sarcophagus is very dangerous and now. The design of the sarcophagus started on 20 May 1986, 24 days after the disaster. [1][2] It was located within a large restricted area known as the Chernobyl Exclusion Zone. Lefaso TV . Browse more videos. The first task before construction started was to build a cooling slab under the reactor to prevent the hot nuclear fuel from burning a hole in the base. inside Chernobyl ЧАЭС sarcophagus 2016 - reactor #4 control room and lead-lined corridors. A third, more massive member, the “Mammoth Beam”, spans the largest distance across the roof from east to west and assists in supporting the roof beams and panels. Chernobyl's new sarcophagus took two decades to make. How much of radiation are in Chernobyl inside the sarcophagus? The construction process consisted of eight stages: The existing Object Shelter is primarily supported by the damaged remains of the Unit 4 Reactor Building, which are largely considered to be structurally unsound as a result of explosive forces caused by the accident. The Chernobyl Nuclear Power Plant sarcophagus or Shelter Structure (Ukrainian: Об'єкт "Укриття") was a massive steel and concrete structure covering the nuclear reactor number 4 building of the Chernobyl Nuclear Power Plant.
