if they sent in a 'cleanup crew' to that reactor the cleanup crew would get pissed off by the crew that's currently dropping thousands of gallons of water onto the reactor from a helicopter.

well obviously that would only be in the case that the helicopters are able to stabilize the situation. they aren't going to send in a cleanup crew to an area full of radiation..... come on now.

dude... thats what im saying.
they want to send in a clean up crew which is why everyone is upset. its a god damn suicide mission.'

And, NHK reports are that pressure is rising in Reactor No.5

its not a suicide mission cause they aren't going to send in a cleanup crew if the situation gets worse....

I wonder why they don't have more effective coolants than water and the likes?
One would think liquid nitrogen or something similar would be far more effective.

The worst that could happen? Its a 30.0 richter scale earthquake causing the president to trip and fall, accidentally entering the nuclear launch codes on his 'football' causing a global nuclear war.

wooooooord nice single emoticon reply brobrooooo. why even bother making a post?
it just seems to me that you don't understand the japanese government is smart enough to know not to send a cleanup crew in immediately after a meltdown with knowledge of mass amounts of radiation in the area, which it currently seems like you think they would do such a thing.
blah i just realized im wasting my time trying to get you to understand something that doesn't even really concern you.

its because they're next to the ocean. imagine how much a pure liquid element would cost to dump onto this thing. especially compared to sea water. it just isn't practical.

not to mention the fact that dropping something that cold on a hot object would cause it to shatter and make the problem worse.

Dude. I know. We already went over all of this previously.
But why are we sitting here talking about how fast the roads got fixed. Anyone with a brain know they need roads there but thats common knowledge.
The real problem is of course the nuclear situation. Roads??
Where we're going we dont need roads...

Now stop with the road garbage!

Oh I know it would be expensive and impractical but if expensive and impractical is all that can avert disaster than I don't think its a big deal to fork out the cash.
But sea water is about 60 degrees - liquid nitrogen is about -180~ I believe... the reactor if ran without coolant could easily surpass 6,000 degrees - I doubt it would shatter it. But even if it did, perhaps that would be enough to cease fission? Isn't around 100kg of fissile material required for fission to sustain itself?

besides costs for the material itself... there are logistical issues with getting that much nitrogen, if it exists, into those reactors in japan. they can barely get that seawater in there... how are they going to get liquid nitrogen in there? invent new technology? the transmission lines will be operational soon anyway.

Well my only point is that water isn't a great coolant and there must be something better No doubt it exists though - liquid nitrogen is used and shipped on industrial scale.
And they've been using helicopters to dump buckets of water on the reactors The days of using the plant infrastructure to cool the reactors are well behind them.

Nuclear fuel IS a self-sustaining chain reaction, it's just happening slowly.
Dumping liquid nitrogen on it could cause more than a crack. It could easily cause an explosion.
Not all explosions are caused by fire. Any rapidly expanding gas can be as destructive as a bomb. That would be very bad, because another explosion at this point could spread nuclear fuel EVERYWHERE.

Meh as I see it - pouring nitrogen is far less dangerous than water - nitrogen releases nitrogen which is non-explosive... water releases hydrogen and oxygen which go BOOM. (the cause of all of the previous explosions there..)
Neither gas expands much quicker than the other as my knowledge is concerned - at least when confronted with an object pushing the thousands of degrees... simply a matter of efficiency of cooling with a -180 degree substance than a 50 degree substance.. But on the other hand you can get much more of the 50 degree substance than the -180 one.

Cooling with liquid nitrogen ISN'T efficient. In all likelihood, it'd boil off before it came anywhere close to touching the rods.
