Chernobyl. Chernobyl is considered the world's worst nuclear disaster to date. It occurred on April 26, 1986, when a sudden surge in power during a reactor systems test resulted in an explosion and fire that destroyed Unit 4. Massive amounts of radiation escaped and spread across the western Soviet Union and Europe A failed cooling system at a military nuclear waste reprocessing facility caused a steam explosion that released 70-80 tons of highly radioactive material into the environment. Impact on local population is not fully known The April 1986 disaster at the Chernobyl a nuclear power plant in Ukraine was the product of a flawed Soviet reactor design coupled with serious mistakes made by the plant operators b. It was a direct consequence of Cold War isolation and the resulting lack of any safety culture. The accident destroyed the Chernobyl 4 reactor, killing 30. In October of 1957, the UK faced its worst nuclear power accident in history. [1] The accident ranked a high level of 5 on the International Nuclear Event Scale. [3] It all started with a routine annealing process that was carried out to regulate the levels of Wigner energy stored in the graphite moderators Today Japan's nuclear safety agency has raised the nuclear alert level for Japan from four to five - making it two levels lower than the Chernobyl disaster in 1986
