10-kilometre and 30-kilometre Zones. The Exclusion Zone was established on 2 May 1986 soon after the Chernobyl disaster, when a Soviet government commission headed by Nikolai Ryzhkov [ 8]: 4 decided on a "rather arbitrary" [ 6]: 161 area of a 30-kilometre (19 mi) radius from Reactor 4 as the designated evacuation area.
A security checkpoint in the Chernobyl Exclusion Zone, 2010. The Chernobyl disaster in 1986 released large quantities of radioactive material from the Chernobyl Nuclear Power Plant into the surrounding environment. [9] The area in a 30 kilometres (19 mi) radius surrounding the exploded reactor was evacuated and sealed off by Soviet authorities.
The New Safe Confinement ( NSC or New Shelter) 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 ...
