Chernobyl is about northeast of Kiev, and approximately southwest of the Belarusian city of Gomel and 16 km [10 mi] from Ukraine’s border with Belarus. The city was the administrative center of Chernobyl Raion (district) from 1923 until it was disestablished in 1988. Before its evacuation, the city had about 14,000 residents. The city was evacuated on 27 April 1986, 30 hours after the Chernobyl disaster at the Chernobyl Nuclear Power Plant which was
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
