The writer of this post starts with
"Relax: this is not another Chernobyl or Three Mile Island, and I'll tell you exactly why. The only thing to fear is the sensationalist reporting that has the world panicked."
and in his update he writes this
"The frustrating part about writing on this stuff is that people don’t seem to have any middle setting between “everything is fine” and “run in circles scream and shout”. So saying “no, it’s not Chernobyl” is interpreted as “it’s nothing.”
So let’s go ahead and make this clear: no, it’s still not Chernobyl. But no, it’s not nothing."
It's a long read, but if you are interested in this nuclear explosion it's worth it
