The Iris map is quite different. BTW,I bumped your Chernobyl thread,because it is relevant to what is happening now in Japan.

Did I read right,they are now spraying from the air,to cool down the reactors?

those pilots have to be getting dosed.....lead plate my ass these people are giving there lives to try to stop this they better be getting medals for this and it better work....

Yes ..you can see operation live

Thanks Xavi..........

This is incredible. I feel sorry for those pilots.

They are heroes

0121: The helicopters are gone now, in order to minimise the crews' exposure to radiation - NHK.
0118: That's four loads of water dropped - NHK.
0117: A lead plate is attached to the bottom of each chopper and the crew are wearing protective suits - NHK.
0115: These are CH-47 Chinook helicopters. Each would normally have a crew of three: pilot, co-pilot and flight engineer.
0114: Eleven water cannon trucks are on their way to the plant - NHK.
0112: Let's recall what top US nuclear official Gregory Jaczko had to say about the risks facing the crews fighting to cool down the reactors: "It would be very difficult for emergency workers to get near the reactors. The doses they could experience would potentially be lethal doses in a very short period of time."
0110: And US nuclear experts believe there is no water left in Reactor 4's cooling pool, meaning radiation levels are extremely high there.
0108: The reason Reactor 3 got the first shower is because of escaping smoke or steam, indicating water evaporating from the cooling pool, Reuters news agency notes.
0106: This is no easy task for the chopper crews. They can't afford to hover above the reactors because of the radiation so they are making the drops in passing.
0104: Just seen a third load of water spraying from a chopper. Seems it was aimed at Reactor 4.
0102: It was feared yesterday that Reactor 3 might have released radioactive steam due to damage to its containment vessel.
0059: Can see a white curtain of water dropping on the reactor from a helicopter, live on NHK TV.
0057: There are two helicopters now working above Reactor 3 - NHK television. Each is capable of dropping 7.5 tonnes of water, it says.


I cant beleive they are still trying to cool the thing. Its time they poor in the cement imo.

reply to post by shikori


i thought they had to stop the reaction to pour in cement wont the cement and lead mixture they use not be able to solidify and last time i checked concrete curing produces epic ammounts of heat......i think they have to stop the meltdown b4 they can pour concrete but i am no expert

I don't think it is that easy to pour the concrete in EITHER.
I think that is probably very hard to do as well, and that it isn't a be all end all cure either.
I think a miracle is needed.

From my point of view, pouting concrete, which has water mixed in would not work until the rods are cooled. The rods are going the wrong direction for that to happen it seems. The water in the concrete would vaporize causing more steam and helping to spread radiation, the remainder would become sand I guess but at over 1500 - 1700 degrees sand would melt and since the temps are so high stay in a liquid form. Even if you could drop concrete and it some how solidified hte rods are still melting downwards not upwards, the problem is not solved.

So why not use liquid nitrogen?
Like a halon system,.
It would cool and remove the oxygen

Screengrab of the water dumps from NHK.

Is it just me or does it seem things are REALLY bad when they have resorted to spraying water from fly-by helicopters onto reactors in the midst of nuclear meltdown?

Any word on the attempts to bring a new power line to the reactors? It sounds like that's the last hope in this cluster---- of a situation.

with all the available generators in the world
why do they not have power to run the pumps yet?

Things ARE that bad. This is like trying to put out your burning house by taking a pee on it, I'm afraid.

As for the power line - don't hold your breath. So much stuff was damaged in the explosions that even if they get full power back on, what will work anymore?

iasked that one a while back and was told its like cold water on a hot engine and would cause boom or cracking of said rods but again no expert

I am close to Toronto area and I did not feel a thing today.

I gave that a lot of thought myself my friend. The problem is you need a cryogenic dewar to transport liquid nitrogen as it is constantly boiling off. Liquid Nitrogen boils at -321 degrees Fahrenheit, thus it would most likely vaporise long before it got anywhere near the fuel, and if it did reach by some miracle, it would vaporise too quickly to have any effect.

This might help, this is a schematic of a fuel rod; I don't know if this is the exact model used in fukushima but it helps vizualising for those of us that are nuclear-reactor-science-challenged:
