I want to write a story about a thought experiment that I have on the other day : What kind of catastrophe will happen if an asteroid, let just say about 70 meters in diameter, penetrated Earth's atmosphere and created an airburst at the altitude of 3.6 Kilometers, directly over the Qinshan Nuclear Power Plant ?
I believe the impact will flattening an area about 2000 Square Kilometers or a little less. I also did my research by read some articles about the Chernobyl Disaster, then the Kyshtym Disaster and Fukushima Daiichi Nuclear Disaster, but I think those aren't enough to answer my question.
So... I want to know what most likely will happen in the aftermath of the event...
Thank you for reading and answering my question :D
