Apart from 1986 there had been two other nuclear accidents in Chernobyl

There were two other nuclear accidents of smaller magnitude than the 1986 accident that took place in Chernobyl at the nuclear power plant before it was finally decommissioned in 2000.

In 1982, there was a smaller accident within Chernobyl’s Reactor #1, but the reactor returned to an operational state within months it was not nearly as significant.

Another accident happened in 1991. There was a fire in Reactor #2 that caused severe damage and ultimately led to the shutdown of this nuclear reactor. Reactor #4 is home to the infamous Chernobyl accident, whereas the other reactors were not permanently shutdown immediately as Ukraine was dependent upon Chernobyl for its electricity production and for the country it would not make economic sense to prematurely discontinue the use of the other reactors. Reactor #1 was permanently decommissioned in 1996 and Reactor #3 was finally retired from operation in 2000.
