This could be very bad news. 1,000’s of tons of radioactive water mixing into the ground water and the sea. We are perhaps brewing something, rather unique, I would suppose. And that is just what is behind door #1, Bob !

What do you think about the bad structural integrity of reactor buildings? If they do crash, I suppose this could create real problems.

“The utility, known as Tepco, has so far pumped roughly 10,000 tons of water into the reactor to keep the fuel rods from overheating. Given that the pressure vessel has a capacity of 360 tons and the containment vessel can hold 7,400 tons, it appears likely that both are damaged.”

What doesn't make sense is that there are three containment vessels involved, the reactor pressure vessel, the drywell, and the containment building itself. The reactor sets inside the drywell which is inside the containment.

There was mention of an effort to flood the drywell and thus submerge the reactor. It's conceivable that the drywell could have been damaged and water is leaking into the containment building. The reactor is holding pressure. That's not an issue.

That leaves the spent fuel pools which are outside the containment building which they used the concrete trucks, fire engine's and helicopters to flood, That was the source of the radioactive water in the turbine building.
