No. Chernobyl is in Russia.
The Chernobyl Nuclear Disaster
There was no famous disaster (or anything else) at Chernobyl in Russia as there is no such place. However for the disaster that occurred in Chernobyl in the Ukraine, please see the related question.
The Chernobyl nuclear plant disaster happened in 1986, when the Ukraine was part of the Soviet Union. Now it is an independent country, though still closely related to Russia.
Russia, the nuclear plant was in the place called chernobyl :)
Chernobyl, Russia
Chernobyl is neither a capital, nor a country. Chernobyl was a city close to the Chernobyl nuclear power station. The power station actually sat close to Prypiat Ukraine, where many of the workers lived. It was close to the Ukrainian and Belarus border. It became famous for having a large nuclear disaster on 26 April 1986. The city is now abandoned and is a ghost city inside the Chernobyl exclusion zone.

Asia, specifically the Chernobyl Disaster in the former Soviet Union (Russia), in which a nuclear power plant went critical and melted down, rendering the city uninhabitable and causing radioactive clouds to travel globally.
The country that was affected most is Belarus, because it is the smallest country and 1 part of 3 is dead. Then goes Ukraine because it is bigger and it least effected. And then goes Russia because it is giant and affected least. Good luck!
