Japan quakes

[Lanek]

One thing that doesn't make sense to me is they are desperately trying to get the power lines up to power the generators but looking at the buildings I find it hard to believe that all the pumps, pipes, electrical systems are intact. Sure they might get some makeshift pumps in but they could only pump water on and in the reactors and pools. For this to work wouldn't all the containments have to be entact? If not wouldn't it kinda be like trying to pump up a popped balloon; it doesn't work.

what you see is the cover of the reactor ( who are open to air ), this can look impressive, don't forget they have got an Earthquake of 9.+ richter. ( now specialist have calculate it to 9.4 ).... but this have happend after the reactors cover explode due to the pressure of the Hydrogen ( water used for cool the fuel is transformed in Hydrogen, the pressure increase and .. well you understand what happend next ) ... the problem at start it's they was not able to cooldown the reactors enough and so the water have become Hydrogen ( loaded of different substance toxic and radioactivity ) ... the problem now is not the cover but the fuel bar who need be constantly cool for don't pass from Fiscion ( normal Thermo nuclear controlled operations ) to Fusion... ( uncontrolled operations, what have happend in Tschernobyl in less of some hours ) .. but if really they can't stabilise it, the only solution will be to cover down all the installation ( concrete and sand sarchophage ).. But it's not Russia.. it's an isle, and so all the life in isle in short, half and long term will be unusable... ) and the damage to the isle ( water, earth contamined and so all life in this region ) this will be so dramatic ( if it can be more ) they try now to don't go to this solution. cause you can cover it for don't get a massive cloud who will hit the peoples but you can't stop what will happend next ( the total contamination of the ground, water etc ) and this is actually impossible to revert..

I thought they said the containment vessells were cracked on some of the reactors?

on the 3 and 4, but don't forget, now the problem is no more the radioactivity released on air, but the real problem is to don't arrive to uncontrollable fusion of the fuel bar... ( the only way is to cool down the fuel bar )
As all the vessel are completelly down ( it's a bit more complicate with the reactors 4 as it's an open vessel ), the only way is to cool down the matters ( who enter in fusion in the contact with the air ),
and so don't go to a similar tcherchnobyl explosion....Whatever is the vessel is open, you need put enough water ( who evaporate in hydrogen ) for keep the bar submerged and cool..... the water can seems a " low" solution, but actually all is in the temperatures of the bar who have been push outisde the reactors ( after the earthquake, it's a securitiy system, the reactor release the bar and in the vessel who are then continuously refresh, immerged in the water, but this exactly where the problem have occur, as the all the safety system have been destroyed and bring unusable after the tsunami who have follow.... the temperature have increase and the level of Hydrogen pressure have make explode the covers of the reactors ......... )

Fission, not fusion. Not even the sun can fuse uranium.

So much for the tsunami protection walls...

Danger rating is up to 5/7 from 4.. :/

Which is still under-rating the event... 3mile was 5/7 and now we have 3 reactors and 4 reactor pools in trouble, all of which are bigger than the 3mile reactor too...

Dctokyo, the fukushima reactor webcam shows a huge cloud of steam?
Which reactor is it monitoring?
Is it dai ichi or ni?

BTW, cnns cover of this event has been terrible.
Today they showed a map where they even labeled the reactors wrong.
1 3 2 4 lol Wtf? ^^

Sorry it seems it was not of the reactor, I removed the link

I found some realtime radiation level map data, some official like stuff here:
https://cdxnode64.epa.gov/radnet-public/showMap.do

Unfortunately it's only for the us.
But it's at least a start, a good chunk of src's in the us isn't to bad...

I noticed in one of the cnn video's they were monitoring the smoke plume I think, but they didn't mention it...
I'm thinking of going to look for that data again...

Can someone interpret the levels seen in some of the California data?
I'm to lazy lol, I found the data, I'm just to lazy to figuer out how to read it.

Edit:
Oh it had hawaii too.
Can someone interpret this... ?

From that link:

Midori Horikawa in Tokyo, writes: "Ungrounded panic and paranoia about the situation in Fukushima are making Tokyo a less than liveable place at the moment. I fear that the alarmist media and reactions of foreign governments are mostly to blame for this mass paranoia. Much of the non-Japanese media's reporting is based on pure speculations, prompting foreigners to leave Tokyo... With foreigners leaving the country, however, even the Japanese are growing distrustful of 'the government stories'. I feel that the whole nuclear scare is just a side show to the very real damage brought by the earthquake and tsunami.

Hear hear...

So much for the tsunami protection walls...

Sounds easy, but a simple wall can't overcome the pressure of a tsunami.

Take the Japan tsunami as an example, the wall has to sustain more than 65000 newtons per square meter of pressure, calculated from an assumed 6m height of the tsunami.
