You're immune to correction, eh?
The pools lost water is the studied reasoning.
Whose "studied reasoning"? And, more to the point, who among them said that they "lost water" because it leaked out of damaged pipes? Much of it is thought to have boiled off... not leaked out. And that couldn't have caused the hydrogen explosions.
We know circulation stopped. When that happened the water heated up and evaporated. Leaving the tops of the rods exposed. Really, this is all such simple physics.
Lol! Yep... it's also a complete change in your story. Thought anyone would miss that?
As to the drawing posted. One, not all the piping and valves (anti-siphon included) worked after the earthquake. Then there were explosions, cranes falling, etc.
How do you imagine that that's relevant? Nothing changes the fact that you thought of those pools as bathtubs with drain holes in the bottom that leaked out the water when the pipes were damaged. That simply wasn't true.
And look closely at the diagram. See the gates into the reactor? What happened if the gates cracked open? Yup, the water drains away.
Yep... and the bottom of those gates is above the tops of the fuel rods... so it couldn't drain below that level. More importantly... there's no possibility that those gates have been repaired... so the fact that the pools are well above that level proves that it didn't happen.
What if a valve in the bottom of the pool broke?
How can a non-existent item break?
How about a crack in the concrete after EQ and explosions, crane fall etc.
There were quite a few of us who worried about that possibility at the time... but nobody can get to such leaks to fix them... so once again, the fact that the pools are currently full already answers the question.
Surely you are not gonna say you somehow know the pools stayed slap full through all the calamity
Of course not. The point was simply that you didn't know what you were talking about. You presented a claim of exploding fuel which never happend.
