The Kyshtym disaster refers to a significant nuclear accident that occurred on September 29, 1957, at the Mayak nuclear fuel reprocessing plant near Kyshtym in the Soviet Union (now Russia). This incident is considered one of the worst nuclear disasters in history, although it is less well known than the Chernobyl and Fukushima disasters. The disaster was caused by the failure of a storage tank containing radioactive waste, which led to a non-nuclear explosion.
