The reason the buildings are still sitting there today is because of the radioactive contamination. Each buildings situation is unique and has been/
is being addressed differently. I'm not saying they aren't doing everything they possibly can, but there are problems with containing it, removing
fuel rods, melted cores and cleanup.
The amount of fuel in these monsters is huge. Hundreds of tons of melted stuff that apparently is still hot and fissioning. That pic of the day of the
steaming ocean is proof there is still activity in these stricken plants.
Something is still generating enough heat to do that. Thats proof there is still fission going on somewhere in there. If they were to put a lid on
that, seal it up, then hydrogen gas from that ongoing fission would begin to build up and could result in more explosions.
The "cover" on number one building is supposed to be controlling the release of these gases from its melted core. Filters are capturing the gases
before venting to the atmosphere. How that is working and what to do with all the contaminated filters is another matter. Sealed up, the gasses would
build until some electric arc in a relay or solenoid would explode the "cover". Other buildings there are just being allowed to vent to the air. That
has been occurring since day one.
The fuel rods present another problem in that to remove them, the damaged apparatus like over head cranes and water trenches have to be rebuilt
enough to allow for removal. All the fuel rods that were ever used in these reactors were being stored on site when the earthquake struck. They didn't
have any place else to store them...
then, and I don't know about now. So the cooling in place continues which, since the pools and cores are damaged is (leaking) and being pumped out
into storage tank farms. I heard that they are at 90 % of capacity for those tank "farms".
The water in these tank farms is still on site because nobody has worked out how to clean it yet or the process is so slow, that the amount of water
is building faster than they can "clean" it (whatever that means).
To build a dam or barrier of some sort down below ground water table--- Wait, what? Think about that for a minute. Even if that were possible somehow,
the whole site would fill up to become a giant swimming pool and eventually run over/under anyway.
Water does that.
Sorry about the doom and gloom, I'm not saying there isn't a solution to this, just looking at the current problems with what they are telling and
