Keeping Memory of the Great Heroic Deed of the Participants in the Liquidation of the Consequences of the Chernobyl Nuclear Power Station Disaster
34 years ago, on April 26, 1986, an explosion took place at the 4th power unit of the Chernobyl nuclear power station, which completely destroyed the reactor. The building of the power unit had been partially collapsed. A fire started in various rooms and on the roof. Subsequently, the remains of the core melted. A mixture of molten metal, sand, concrete, and fuel particles spread through the sub-reactor rooms. In the destroyed nuclear reactor, uncontrolled nuclear and chemical reactions (from the burning of graphite reserves) continued with the release of heat and the eruption from the break for many days of products of combustion of highly radioactive elements and their contamination of large areas.
