50-50 chance of catastrophic radiation leak?

CNN has confirmed the translation. If the Japanese cabinet minister was correct, then the last 50 have been pulled from the plant due to excessive exposure risks.

This is exactly what couldn't happen. I'm not complaining...I understand the risk they were taking to be there, I had just hoped that the levels would stay low enough to allow them to continue without obvious risk of life.

Jim Walsh is almost speechless on CNN. He doesn't understand it. He realizes that there is no one left to mind the ship. If the workers have indeed left, we have three hot reactors with no automated cooling control and no one present to guide manual control. Walsh is fairly adamant that we don't understand something about the situation. He seems to think that this is just a very temporary move or that they are going to cycle in smaller teams to try to maintain cooling and venting.

Sounds like to me they are leaving and not coming back. Said they even stopped minimal duties and are leaving.

Tuned in to CNN based on the above and repeating this hope that there is someting lost in translation.

What about the spent fuel rods?? With them gone, does that mean that they lose water also and be exposed?

Apparently reactor 3 is producing a significant amount of steam, and the source is not fully understood. It wouldn't shock me if this was a big part of the reasoning to evacuate the 50.

NOTE: If you are watching CNN now, recognize that CNN just flipped over to there AC360 replay. Note it no longer says "Live." So, this information will be several hours out-dated.

Not necessarily, at least not on a fast timetable - unless it gets very, very hot inside the secondary containment. It depends on how damaged the ponds and their water management systems are. A big concern is reactor 4 where if another fire occurs, the spent fuel rods could become exposed (further exposed??), leading to failure of the spent fuel rods.

I have heard concerns expressed over the spent fuel that *may* (there are conflicting reports on this) be at reactors 1, 2, and 3, but I have not seen any solid reports that suggest they are in imminent danger.

MSNBC says they left for 45 minutes due to spike in radiation, then went back.

The bad news is, what caused the spike?

That is very good news if true from a meltdown standpoint. The fear, of course, is that if that spike can happen...how many more will happen and how radioactive might it become?

This is an epic freaking disaster. You can see the place burning. They need to shut down any plant like this near any major fault line here in the US asap

Wow. That fire has to be put out. You have to wonder now how much is the hydrocarbon fire from the pumps and how much might be a zircaloy fire.

CNN said this company has a bad history of lieing about safety of plants. Makes you wonder what they are not telling.

there was a guy on foxnews last night who was saying that there was unequivocally no way that the western US would be threatened by radiation ... I'm not sure you can say that

The latest report (11:00 local time on the 16th) doesn't show any change to the water levels in the reactor vessels:

Reactor 1 - Around half of the fuel is uncovered
Reactor 2 - Level is beginning to recover after being DRY
Reactor 3 - Around half of the fuel is uncovered

These may just be rubber-stamp inputs because they don't have any updates, but if true, this means that fuel is being left exposed for hours and hours. If they have to leave again, you have to think the risk of these levels dropping goes up.

Is there anyway they can pull this out?? Every hour it keeps getting worse it seems like. Also, can I ask where you get your info?? Seem to know alot.

Also one thing I wonder about is the workers. How much can they physically take?? You know they aren't sleeping and there are problems with all 6 plants. They are running around a big area trying to solve all these issues. How much food and water do they have and how much radiation have they already been exposed to??

They're doing it already, but uranium isn't like a forest fire at all.

I know that lol. I have a Tennessee Tech degree. I'm sure they have smarter minds than mine on it. I was just wondering about the system of getting the water there and the amount they could dump on it.

They are giving their lives right now.

There is a way, but I am a lot less hopeful than I was two days ago. It's all about buying time now and trying to cool the fuel as much as possible. Worst case is they have to walk away long term and let them meltdown. Then, we just have to cross our fingers that primary containment holds most of it and that any releases to secondary containment are slow and not explosive.

That info came from the same source that Daddy Gee posted earlier. My other info comes from reading various news outlets and from some contacts I have.

More than I have at the moment. They're flooding the area with sea water and then venting the steam when the pressure builds up. There's no way to keep pressure down until the automated cooling systems are back up and running. That would allow the water to flow and cool, instead of sit, cool, steam. As I understand it, since they flooded the chamber then there's no way they can restart automated cooling.
