<P> 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 . It is located within a large restricted area known as the Chernobyl Exclusion Zone . The original Russian name is `` Obyekt Ukrytiye '' ( Объект `` Укрытие '' ) , which means `` sheltering '' or `` covering '' , as opposed to sarcophagus . The sarcophagus locked in 200 tons of radioactive corium , 30 tons of highly contaminated dust and 16 tons of uranium and plutonium . </P>
