1986 – The worst nuclear disaster in history occurs in Chernobyl
Considered the worst nuclear disaster in history, both in terms of cost and casualties, Chernobyl disaster was a nuclear accident that occurred at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR on this day in on 1986. It is also 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 Daiichi nuclear disaster in Japan. The initial emergency response, together with later decontamination of the environment, ultimately involved more than 500,000 personnel and cost an estimated 18 billion Soviet rubles—roughly US$68 billion in 2019, adjusted for inflation.
