The Chernobyl Nuclear Power Plant is a decommissioned nuclear power station near the city of Pripyat, Ukraine. Reactor No. 4 was the site of the Chernobyl disaster in 1986 and the power plant is now within a large restricted area known as the Chernobyl Exclusion Zone. On April 26, 1986, a disaster occurred at Reactor N. 4, caused by a catastrophic power increase resulting in core explosions and open-air fires. This caused large quantities of radioactive materials and airborne isotopes to disperse in the atmosphere and surrounding land. The disaster has been widely regarded as the worst accident in the history of nuclear power in the world.

A giant steel shelter was slid into position over Chernobyl’s crumbling radioactive ruins. The New Safe Confinement (NSC) was deployed in November 2016 to contain radiation from doomed the nuclear power plant for 100 years. The local scenery on the ground is as follows.
