The only ones I see getting outraged and panicked on here are the ones like you saying nothing is wrong.
There’s no sense of scale with your type. It’s either 100% end of the world or 100% everything’s fine.
Chances are, they're long dead. That's how old this design is.
From Reuters again (March 15, 2011, 7:20 PM) :
Radiation poses only slight risk to nervous Tokyo: U.S. experts

EXCERPT
Dozens of workers battling to control radiation at Japan’s stricken reactors face a far greater risk of developing cancer than normal, but Tokyo residents are within the safe range for exposure, U.S. nuclear experts said.
Radiation levels in Tokyo, one of the world’s most populous cities, rose 10 times above average Tuesday evening, spreading fear among many of the 33 million residents in the metropolitan area.
The best advice experts could give them was to stay indoors, close the windows and avoid breathing bad air — steps very similar to those for handling a smog alert or avoiding influenza.
While these steps may sound inconsequential, experts said the danger in Tokyo, while worrisome, is slight - at least for now.
“Everything I’ve seen so far suggests there have been nominal amounts of material released. Therefore, the risks are generally low to the population,” Jerrold Bushberg, who directs programs in health physics at the University of California at Davis, said in a telephone interview.
“There may be more significant risks for emergency workers on site. They are dealing with the occupational exposure, but not for the population at large.”
Fresh explosions Tuesday at the Fukushima plant, 180 miles north of Tokyo, released low levels of radiation, escalating a crisis triggered by last week’s massive earthquake and tsunami. With cooling systems knocked out, the fear is more blasts within the reactors at the complex could eventually cause a major radiation leak.
The levels measured around Tokyo at one point were 40 times above normal but have receded to 10 times. That amounts to roughly the same dose as a chest or abdominal CT scan.

Correct. Earlier today there were reports that 5 annd 6 were experiencing increasing heat content in their storage pool.
My understanding is that there were 6 usable reactors three of which were on line. I also read a report that they are in the process of building two more on site, so that would make 8 in total.
Thanks, just wanted to make sure I heard that right.
IAEA to send experts for environment monitoring to Japan soon...
IAEA isn’t even in Japan, yet...

“”How many reactors or on site?””
From a post I made this morning...
“There are 6 units at Fukushima 1 (Dai-Ichi) generating plant. 1, 2, and 3 were on line at the time of the earthquake, while 4, 5, and 6 were in cold shutdown for inspection. When they lost backup and off-site power, ALL units lost cooling. But with the latter 3 units already in cold shutdown, they were not nearly as critical a problem as the first 3 units.
Units 1, 2, and 6 are GE, 3 and 5 are Toshiba, and 4 is a Hitachi.
There is also a Fukushima II (Dai-Ni) generating plant. It is a separate facility about 11 KM south of Fukushima I. It has 4 generating units, approximately 1100 MW each. At that plant, units 1 and 3 are Toshiba, while 2 and 4 are Hitachi. Fukushima II never lost off-site power and therefore has been able to properly cool the 4 units after they tripped as a result of the earthquake.”
A very cheap & worthwhile investment considering.
Very easy peasy japanesy to be snide & condecending, but it sure would it be nice if this problem hadn't been added to all the others?
Thanks for the explanation!
Yeah, and I think a lot depends upon how many fires keep breaking out at No. 4.
I’m still concerned about the damage done to No. 2. There were conflicting reports this morning, but JAIF has an update noting suspected damage to containment:

Can you try that again? I don’t understand what you are trying to say.
Thanks for your post. I’ve also watched another report.
They were considering using helicopters through the roof to cool, but decided against it. So, not sure if roof integrity is a hindrance or an opportunity.
If the roof crack significance is an avenue for leakage, I would think the large holes in the walls would be enough anyway.
Perhaps it is a worry of roof collapse.
Or maybe the headline of roof crack is of little meaning other than another excuse for a headline.
I appreciate the information and effort of your post.
Re. post 110 - that’s a very informative chart. Thanks.
Maybe if they keep an updated chart like this, we can circumvent the media hysteria circus and know much better what is going on.
No matter how much it costs, in the long run it would be an infinitesimally tiny speck on their precious squirmy & slimy bottom line.
I can believe that the rods are damaged in 1 and 2 - probably unit 3 also.
The spent rod pools are at atmospheric pressure, yes?
You, sir, are a Professional. Thank you.
I think that they are, but I defer to someone with nuclear experience to give you a definate answer.
The spent fuel pool isn’t sealed. It may be covered so no one falls in, but it’s a pool. These pools need to be full of water, or really bad things can develop.
