The twisted fuel bundles still attached to it are called Elena's hair. The design of the sarcophagus started on 20 May 1986, 24 days after the disaster. 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. The shield, called the pig's nose (Пятачок: Pyatachok) before the disaster, was afterwards named Component E and nicknamed Elena. [8] The western end of the shelter roof is supported by a wall at a point designated axis 50. [6][verification needed] The sarcophagus has over 60 bore holes to allow observation of the interior of the core. This is a large new sarcophagus over the destroyed block of ChNPP # 4. The reactor was not completely collapsed. [7] Filtration systems have been put in place so that no radioactive material will escape through these holes.[7]. On April 26, 1986, the core of a nuclear reactor at the plant … 4 in Chernobyl Nuclear Power Plant, Ukraine, 2nd October 2014 Photograph: Alamy Arthur Neslen Fri 24 Apr 2015 06.28 EDT The two "Mammoth Beams" that support the roof of the shelter rest partly on the structurally unsound west wall of the reactor building that was damaged by the accident.

The Chernobyl nuclear power plant's massive "sarcophagus," which protects its radioactive reactor, is being dismantled because it could collapse. 2 A … His slideshow from that visit offers a unique historical snapshot of the conditions and challenges inside the plant. To prevent radiation leakage from the exploded 4 reactor at the Chernobyl NPP, a special protective complex was built. Chernobyl is not the only nuclear disaster site benefitting from the RoboCrane technology. Constructed New Safe Confinement in 2016. The Soviet authorities started the concrete sarcophagus to cover the destroyed Chernobyl reactor in May 1986 and completed the extremely challenging job six months later. [5] When the building became overly radioactive, it became impossible to directly screw down the nuts and bolts or apply any direct welding to the sarcophagus, so this work was done by robots. This article is about the original containment. That cover was designed to be sturdy, but as Business Insider reports, over the years corrosion has occurred due to water finding its way in via openings in the ceilings and the building's unsealed joints. [Chernobyl Nuclear Power Plant, Ukraine 2011] From the rooftops of the nearby city of Pripyat, the first section of the New Safe Confinement can be seen. Powered and implemented by FactSet Digital Solutions. When the nuclear reactor's core exploded during a safety test in April 1986, sending poisonous plumes of radioactive waste into the air that spread to parts of Russia and Europe, thousands of workers scrambled to build a gigantic concrete and steel covering to contain the radioactive materials that included uranium and plutonium. The UBS is a disk 17.7 meters in diameter, weighing 1000 tons and consisting of 2000 cubes, each located above a fuel channel.
