The release of a large amount of radiation, the death of about 50 firefighters and plant staff, the evacuation of the neighbouring town and area.
No. Chernobyl is in Russia.
At the power plant at Chernobyl in the Ukraine

The nuclear plant explosion of 1986
Yes, it did.

When and what explosion? One of the nuclear test shots. If so which?Remember Chernobyl was not a nuclear explosion, it was a steam explosion and graphite fire.
Chernobyl
No
The bombs dropped in Japan were designed to produce a large nuclear explosion which produced heat and blast waves. At Chernobyl an operating reactor lifted its top off due to a surge in pressure, and this flung out radioactive debris, not as a result of a nuclear explosion but due to mechanical forces. There was approx. 400 times the amount of radiation released from Chernobyl than there was from the two bombs dropped on Japan.
I believe your mistaking Russia with Ukraine in which case it would be Chernobyl. Hope that's it.
The both ultimately resulted in the release of radioactive material from a nuclear reactor into the environment.
