Point is, if our DOE is studying robotic applications in arenas such as nuclear reactors, you can be certain the Japanese are as well. Thrye still having sizeable and earth moving aftershocks AND separate earthquakes on an entirely different fault line as discussed in this very important thread and could be the precursor of yet more tectonic releases in the area.

Ok I agree upto certain extent but does this mean that you let the other reactors run and not shut them down just because there is impending earth quakes? How do you shut the reactors(atleast the one's that are not damaged) down if there are no individuals at the Nuclear Plant?

It is just amazing to me at times that many countries brag and create a big hoopla about posessing cutting edge technology to pretty much tackle anything and everything that could be man made calamity. However when SHTF which is man made (nuclear reactor) there is always a dilemma. Wouldn't the Engineers would have thought about the Worst Case Scenario for a nuclear power station? Just curious.

How much of the run on iodide tablets is panic and how much of it is meth?
I wonder if the real run on iodine tablets is the meth heads finding a use for it. I know they made strong iodine solutions illegal b/c of them. Just sayin.

The media is really pushing this idea of US panic. Some of it might be folks just wanting it for survival kits too.

I think maybe their assessment of what a worst case scenario would be was a bit flawed or they wouldn't build nuclear reactors right next to the pacific on a subduction zone. Or at the very least they wouldn't have had their diesel backup generators right by the water.

Engineers are notoriously conservative in estimations alon with being known for "over-engineering" tolerances.

Unfortunately, it seems that they were also quite short of the mark when the designed for around a 7.5 maximum or so where earthquakes are concerned. It's nigh impossible to wrap ones head around the amount of energy released in the megathrust quake, so some thought must be given to how you might build to withstand that. About the only thing that comes to mind are the great pyramids and I don't know how those would withstand suh earth shaking.

Seems like someone dropped the ball during the design phase. I heard yesterday that one of the government staff of Japan was using profanities while conversing with Top TEPCO officials expressing displeasure with the entire situation with the plants.

Assuming by the laws of physics and chemistry, the pyramids will crack and partially crumble.

I saw a segment on CNN last night where they were showing the Japanese robots. One is a snake with a camera that can crawl thru rubble, one that goes up uneven stairs, etc. No telling where the robots are housed and it may have been difficult to get them to the scene - just saying. But with all the technology it would be good to put then to use.

Could this one handle a fire house?

Somewhere in all this - talking about design/preparedness flaws- I heard that when they brought in the deisel generators to use for cooling - a early failsafe- that the PLUGS weren't the right shape.

I don't have a source, that's one of those things I've read so far back I can't remember where I read it. But come ON. That's like not having an extension cord on a crash cart to power the defibrillator with.

Isnt that a shame? Something doesnt seem right with the amount of information coming out of Japan and the Government.

I can see over engineering tolerances for the appearance and size of a particular design. I would never try to underestimate the worst case scenario when it comes to safety.

The US is advising its citizens living within 80km (50 miles) of Fukushima to evacuate or stay indoors.

80km - sounds like they're being a lot more cautious than the Japanese!

has there been any aftershocks lately? the ones yesterday around fiuji where really a little scary. any info?

It gets worse and worse with every hour. A big chunk on Japan is gone for thousands of years, that's for sure.

I think I heard that electronic circuitry gets destroyed in heavy radiation.

I believe the Tokyo Bay area is now diminishing its energy gradually. I wouldn't be too surprised to see some mag 6-7 quakes in the Bay in the near future. However my next concern is watching the pattern on the USGS map.
Along the Megathrust fault you can see to the North there's a large area of area unaffected by aftershocks which propegate into the main sequence, I have a particular strong feeling this region will be seeing something in the magnitude of a +8 if not within this week left to come.

I'm starting to lose track....

Is there still a fire at number 4 reactor? Any more news on the temps at 5 and 6?

They are developing robots to deal with radiation looks like American scientists in this case though.

I don't know how old that story is or how it worked out for the robots.
