I'm starting to get a feeling that these guys are getting overwhelmed and don't have the resources to fix the problem.

Huge problem actually. Its estimated that the Fukushima Daiichi plant may contain over 600,000 spent fuel rods.

The fuel rods must be kept submerged in water. Why? Outside of the water bath, the radioactivity in the used rods can cause them to become so hot they begin to catch fire. These fires can burn so hot the radioactive rod contents are carried into the atmosphere as vaporized material or as very small particles.

There saying it would be like Chernobyl on steroids. Chernobyl contamination settled upon people and nations thousands of miles from that reactor’s location. How far would “Chernobyl on steroids” travel?

No need to worry tho, I am sure they will get the fire put out.... grabs lead suit and runs...

What isnt clear is what is burning....If its the spent fuel its pretty disasterous!

Yeah I dont think there are many workers left from what I hear. If GE designed it you would think they would have a team to help or spare parts, something for god sakes.

you mean nuclear fission?

The fire was noticed by an employee in the control room of Reactor 4. It is thought to have been caused by water level dropping in the spent fuel pool, then a similar hydrogen explosion to the other explosions. According to NHK, they currently cannot put the fire out, due to increased radiation in the pool.

That being said, as long as this fire is contained within the concrete building, it shouldn't be a huge risk...

scratch that, NHK just confirmed there is a hole in the roof, into which they will attempt to help-drop water to extinguish the fire / cool the spent fuel.

Note that I'm just posting this as I hear it from NHK.

Oh that's cool. So the radiation levels are too high for them to put out the fire, but the fire could potentially be releasing much more radiation every second?

Goodie. Time to order your iodine pills!

I fail to see how it will just go out naturally, this has gone on so long now I think all the power company is trying to do is gain more time before the inevatable happens (whatever that may be).

The guys working round the clock must be physically and metally exhausted!

At some point someone is going to have to man up and manually fill these cooling tanks via firetruck hose.
