The Chernobyl Nuclear Power Plant or Chernobyl Nuclear Power Station is a nuclear power station under decommissioning near the city of Pripyat, Ukraine, 14.5 km (9.0 mi) northwest of the city of Chornobyl, 16 km (9.9 mi) from the Belarus–Ukraine border, and about 110 km (68 mi) north of Kiev. 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. Both the zone and the former power plant are administered by the State Agency in Administration of Exclusion Zone (Ministry of Ecology and Natural Resources).
The nuclear power plant site is to be cleaned by 2065. On January 3, 2010, a Ukrainian law stipulating a programme toward this objective came into effect.
On Saturday, April 26, 1986, a disaster occurred at Reactor No. 4, which has been widely regarded as the worst accident in the history of nuclear power in the world. As a result, Reactor No. 4 was completely destroyed and is being enclosed in a concrete and lead sarcophagus to prevent further escape of radioactivity. Large areas of Europe were affected by the accident. The radioactive cloud spread as far away as Norway.
