Chernobyl disasterThe Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. Called the world's worst-ever civil nuclear incident, it is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear disaster in Japan.
Ghost townA ghost town, deserted city, or abandoned city is an abandoned village, town, or city, usually one that contains substantial visible remaining buildings and infrastructure such as roads. A town often becomes a ghost town because the economic activity that supported it (usually industrial or agricultural) has failed or ended for any reason (e.g. a host ore deposit exhausted by metal mining). The town may also have declined because of natural or human-caused disasters such as floods, prolonged droughts, extreme heat or extreme cold, government actions, uncontrolled lawlessness, war, pollution, or nuclear disasters.
Chernobyl exclusion zoneThe Chernobyl Nuclear Power Plant Zone of Alienation is an officially designated exclusion zone around the site of the Chernobyl nuclear reactor disaster. It is also commonly known as the Chernobyl Exclusion Zone, the 30-Kilometre Zone, or The Zone. Established by the Soviet Armed Forces soon after the 1986 disaster, it initially existed as an area of radius from the Chernobyl Nuclear Power Plant designated for evacuation and placed under military control. Its borders have since been altered to cover a larger area of Ukraine.
Chernobyl Nuclear Power PlantThe Chernobyl Nuclear Power Plant (ChNPP; Чорнобильська атомна електростанція; Чернобыльская атомная электростанция) is a nuclear power plant undergoing decommissioning. ChNPP is located near the abandoned city of Pripyat in northern Ukraine northwest of the city of Chernobyl, from the Belarus–Ukraine border, and about north of Kyiv. The plant was cooled by an engineered pond, fed by the Pripyat River about northwest from its juncture with the Dnieper.
Chernobyl New Safe ConfinementThe New Safe Confinement (NSC or New Shelter, rarely Arka) 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 reactor immediately after the disaster. The New Safe Confinement is designed to prevent the release of radioactive contaminants, protect the reactor from external influence, facilitate the disassembly and decommissioning of the reactor, and prevent water intrusion.
Chernobyl (miniseries)Chernobyl is a 2019 historical drama television miniseries that revolves around the Chernobyl disaster of 1986 and the cleanup efforts that followed. The series was created and written by Craig Mazin and directed by Johan Renck. It features an ensemble cast led by Jared Harris, Stellan Skarsgård, Emily Watson, and Paul Ritter. The series was produced by HBO in the United States and Sky UK in the United Kingdom. The five-part series premiered simultaneously in the United States on May 6, 2019, and in the United Kingdom on May 7.
Nuclear fission productNuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons, the release of heat energy (kinetic energy of the nuclei), and gamma rays. The two smaller nuclei are the fission products. (See also Fission products (by element)). About 0.2% to 0.4% of fissions are ternary fissions, producing a third light nucleus such as helium-4 (90%) or tritium (7%).
Russian invasion of UkraineOn 24 February 2022, in an escalation of the Russo-Ukrainian War which began in 2014. The invasion has killed tens of thousands on both sides. Russian forces have been responsible for mass civilian casualties and for torturing captured Ukrainian soldiers. By June 2022, about 8 million Ukrainians had been internally displaced. More than 8.2 million had fled the country by May 2023, becoming Europe's largest refugee crisis since World War II. Extensive environmental damage, widely described as ecocide, contributed to food crises worldwide.
ChernobylChernobyl (tʃɜːrˈnoʊbəl , UKalsotʃɜːrˈnɒbəl ; Чернобыль, tɕɪrˈnobɨlj) or Chornobyl (Чорнобиль, tʃorˈnɔbɪlj) is a partially abandoned city in the Chernobyl Exclusion Zone, situated in the Vyshhorod Raion of northern Kyiv Oblast, Ukraine. Chernobyl is about north of Kyiv, and southwest of the Belarusian city of Gomel. Before its evacuation, the city had about 14,000 residents (considerably less than neighboring Pripyat).
KyivKyiv, also spelled Kiev, is the capital and most populous city of Ukraine. It is in north-central Ukraine along the Dnieper River. As of 1 January 2022, its population was 2,952,301, making Kyiv the seventh-most populous city in Europe. Kyiv is an important industrial, scientific, educational, and cultural center in Eastern Europe. It is home to many high-tech industries, higher education institutions, and historical landmarks. The city has an extensive system of public transport and infrastructure, including the Kyiv Metro.
