I deleted it because I forgot the water leaking out, but here's the original comment because it might be interesting.

"If I've understood everything correctly, it can't be as bad as the Chernobyl disaster. The only reason to why the radioactive material spread so far during the Chernobyl disaster was because the reactor core consisted of graphite, the graphite caught fire, and the dangerous material rose to the sky."

@jjsz The text is the same. What happened was that I deleted the comment before I saw that someone replied to it, and then it looked stupid with a good reply to a deleted comment.
