Chernobyl New Safe Confinement

The New Safe Confinement (NSC or New Shelter; Ukrainian: Новий безпечний конфайнмент, romanized: Novyy bezpechnyy konfaynment) is a structure put in place in 2016 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. The structure also encloses the temporary Shelter Structure (sarcophagus) that was built around the reactor immediately after the disaster.
