Chernobyl Nuclear Power Plant Chernobyl Nuclear Power Plant The Chernobyl Nuclear Power Plant or Chernobyl Nuclear Power Station (, "Chornobyls'ka Atomna Elektrostantsiya", , "Chernobyl'skaya AES") is a decommissioned nuclear power station near the city of Pripyat, Ukraine, northwest of the city of Chernobyl, from the Belarus–Ukraine border, and about 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 of Ukraine of the Exclusion Zone (Ministry of Ecology
Tihange Nuclear Power Station power plants these were already built in after the nuclear disaster in Chernobyl in 1986. Other countries followed this example, latest after the Fukushima nuclear disaster. This kind of system allows for the containment pressure to be relieved in the event of a severe accident. The non-condensible gases that cause pressure within containment to rise are released through a stack (or chimney) via a filtration system that removes large quantities of fission products from the effluent. As part of the stress tests following the Fukushima incident, this issue had already been identified to be included in the stress-test action plan
