NuclearPow: nobody fully knows what happened to the reactor
Supercrafter: Apparently, Workers of Chernobyl Nuclear Power Plant pulled a lever that pulled the control rods down. However, those rods could not go down because of steam in the reactor, and those rods went down a little bit. Because of this, reaction in the rods went really fast. Then pressure pulled this rods up, causing extreme reactions in UO2.
remove termite from the reactor ...
den_koshkin: reply to my conversation, if you even are there online!
den_koshkin: well, I was watching N24, now known as world where they started the test, got the reactor down to a safe 750 MW and then when it was going the reactor dropped in power and the first reaction was to pull the rods out, and then the power got back up but once the rods dropped the power escalated, causing extreme problems such as overheating and it melted down
You mean on the bottom control panel?
den_koshkin: destroy able lights and buttons?
Hmm, even better to say that an extremely unlikely set of circumstances occurred.
