Chernobyl Nuclear Power Plant sarcophagus The Chernobyl Nuclear Power Plant sarcophagus or Shelter Object (Ukrainian: Об'єкт "Укриття") is a massive steel and concrete structure covering the nuclear reactor No. 4 building of the Chernobyl Nuclear Power Plant. It was designed to limit radioactive contamination of the environment following the 1986 Chernobyl disaster, by encasing the most dangerous area and protecting it from climate exposure.[1][2] It is located within a large restricted area known as the Chernobyl Exclusion Zone. The original Russian name is "Obyekt Ukrytiye" (Объект "Укрытие"),[3] which means "sheltering" or "covering", as opposed to sarcophagus.[2] The sarcophagus locked in 200 tons of radioactive corium, 30 tons of highly contaminated dust and 16 tons of uranium and plutonium.[1]
