I can do one! At one point they send in three people in scuba suits to drain the water out of the suppression pool. It is said that if the core falls into the water, a steam explosion with the force of (I believe it was) 4 megatonnes would occur, rendering Europe uninhabitable for decades.
Well, it turns out that if you postulate a fully liquid chernobyl fuel core and take its heat capacity and use that to vaporize an infinite supply of water (an easy worst-case thermodynamic calculation), you can see that this estimate was off by roughly 5 orders of magnitude. Someone said it best along the lines of: "if that were true, Hawaii would be blown off the face of the map multiple times daily."
Yeah, that was unfortunate. An engineer really did say that at a similar meeting but they were very wrong and everybody quickly realized they were wrong.

Classic scare-mongering dramatic BS.
