FBaggins,
As you know, Arnie Gundersen is a first-class IDIOT.
I remember his video in which he claimed that the Unit-3 explosion was a "nuclear explosion". I can give you a whole litany of why he was 100% WRONG about it being a nuclear explosion.
However, one part of his explanation, the above picture certainly disproves. Gundersen claimed that the Unit 3 fuel pool had to be empty / dry. The reason he came to that conclusion was because the mushroom cloud of the Unit 3 explosion had a stem with material moving upwards.
IDIOT Gundersen claimed that could only happen if it was "focused". He said that the explosion had to take place deep down inside an empty / dry Unit 3 fuel pool, and that an explosion at the bottom of the pool was "focused" upwards by the vertical walls of the fuel pool.
Gundersen is a DAMN IDIOT masquerading as someone who is scientifically competent.
Mushroom clouds are the hallmark of a Raleigh-Taylor instability that you get whenever you have an explosion. Mother Nature doesn't like to push more dense fluid with less dense fluid. When you have an explosion, you have hot, less dense air sitting under the cooler, more dense air above the explosion. The air underneath has to support the air above. Hence you have less dense fluid exerting a force on a more dense fluid. When that happens; you get a mushroom cloud.
If anyone thinks about it; we got mushroom clouds when we exploded nuclear weapons high on metal towers in the Nevada desert with nothing around. Where were the focusing walls in the Nevada desert.
If you are not a scientist, and don't know your science; and you hear Arnie Gundersen saying anything technical; your best bet is to consider that anything that IDIOT says is 100% WRONG.
This is just another in a long litany of things that Gundersen has been proven wrong on. Anybody that believes him in the future, has got to be as abjectly STUPID as Gundersen.
