Hmmmm... I'm not sure what to make of that...
“Everything in their system is built to build consensus slowly,” said one American official who would not be quoted by name because of the delicacy of discussions with Japan. “And everything in this crisis is about moving quickly. It’s not working.”
rhody said:From the NY Times piece above, simply stated, this is the undepinning reason things are rapidly spinning out of control, with potentially dire consequences for Japan and the world.
Astronuc said:Yes, the consequences are different if one is directly affected. If one is on the plane that crashes, or one's family member or friend is lost, then I would imagine one would be quite emotional.
This Wall of Shame is being assembled by various people, many of whom are on the ground in Japan as residents, not temporarily assigned journalists, who are sick of the sensationalist, overly speculative, and just plain bad reporting that has gone on since the Tohoku quake in Japan last Friday (March 11). We feel that contacting each and every publication and reporter every time a bad report shows up is not effective, and it is our sincere hope that this will encourage journalists to aspire to a higher (some would say minimal) level of responsibility in their reports. If you would like to add a report of your own, feel free.
WhoWee said:Watching these efforts to carry water and pump from trucks makes me wonder why they couldn't couple a few hundred feet of oil pipe together - to be attached to fire hose - and drug into position by the helicopter - maybe weigh-down the end to keep in position over pool. This would allow a continuous supply of water pumped from the bay.

Faith in the safety nuclear power plants or aircraft is only as good as the practices. As long as there are not accidents, then there is confidence. An accident challenges that confidence, according to the severity. The performance is only as good as the training and dedication of those operating the plants or flying the aircraft.
As far as I know, the book doesn't cover the situation after they lose EDGs and emergency power supply. Now they are outside of their emergency operating procedures (EOPs) and more or less flying by the seat of their pants.Proton Soup said:one normally expects the japanese to do everything by the book. so, I'm curious as to whether you think the plant operators have have succeeded on that metric, and also whether they may have been hindered by a lack of ability to improvise when the situation becomes SNAFU'd.

The problem is lack of information.BobG said:That's becoming pretty obvious. Yet, TEPCO is pretty persistent that they're capable of handling this problem themselves - to the point they're not even willing to share much info on what's actually happening at the facility.
One thing that's bothered me is that they can't run their normal cooling system because of lack of power for their pumps, but they were able to pump in seawater?
Or is it that they don't have the power necessary to run the condensers to cool the water in the closed system, so have to find water from an open system to cool the system indirectly (externally instead of internally), which is a lot less effective.
Or is the seawater a passive system that can only be used for a short term problem (since there's no way to pump the water back out to the sea)?
After a week, they still haven't provided enough information to even know what they've actually done.

What really gets at me is some of the jokes people are making about this.
For instance, one person claims that it's a scam because everything looks fine on google streetview. I think that was meant as an ironic joke.
I also heard some people saying that the earthquake was karma getting a japan for the attack at pearl harbour. Which makes no sense.
I guess some people find it amusing.

Same here. It's funny in the same say a dead baby joke is funny.lisab said:Thankfully those who hold such opinions are in the extreme minority, extrapolating from the circle of people I associate with. Such attitudes sicken me.
Yeah, I know. The reason the logic falls through is because Pearl Harbour was a military installation, and the US destroyed two major cities with a vast civilian population using nuclear devices.jhae2.718 said:Wait, what??!

Moving on though, how are they flying supplies in? The main airport if I remember correctly was built on a man made island.
Astronuc said:The problem is lack of information.
I expect the seawater pumps are small and are being run by portable power generators that were brought in. I heard 'fire hoses' mentioned, but I don't understand the context. I don't really know where the seawater is being introduced, or at what rate.
The physics is just about match flow rate with heat generation rate - matching them so the water in the core doesn't get too hot.
I don't know how open the primary system is - in other words, besides the steam coming off - is there water 'leaving' containment? Is it going into the ocean?
There is a mass balance (a la continuity equation). If Δm or dm/dt in the system = 0, if dm (water)/dt = dm (steam), then there's no net gain/loss of water in the system, and steam is coming out with activity. If dm (seawater)/dt > dm (steam), but Δm = 0 in the primary system/containment, where is the water going? The ocean?
Has the inflow of water to the cores in the RPV been sufficient to cool the fuel? Has the water inflow into containment been sufficient?
The what about the spent fuel pools - particularly the one in Unit 4?
One terrible irony of risk management is the better you do, the more your techniques will come under attack, Kabay said. The longer we go without a dangerous nuclear event, the more safety engineers are accused of overspending.
"The better precautionary measures do, the less effective they appear,” Kabay said. “...There is an exceptional psychological tendency to narrow your functional view and forget the earlier conditions we have improved.” That's why funding for preventative measures against major disasters tend to vacillate over a half-generation. The recent memory of a bridge collapse leads to tougher civil engineering laws; a distant memory leads to accusations of overkill and overbuilding. "Many people start thinking ‘we're wasting money here, we've been wasting all this money on backup systems we never need.’"

FlexGunship said:Likely because of the association with "nuclear weapons." I'm sure a guy named Joe Hitler running for president would have really bad luck but not because of his political views.

nismaratwork said:Besides, Ivan is anti-nuclear, but he knows the difference between 'sizzle' and 'KABOOM'. I want to know why informed and rational people hold a view that I don't understand... the nuts I get, and the people who just hear 'atom' and think 'Ivy Mike', but not others.
FlexGunship said:Here is one of Ivan's previous posts. I'm not sure if his views have changed since then, but he WAS concerned about intentional misuse of a nuclear reactor. (As opposed to intentional misuse of oil.) https://www.physicsforums.com/showpost.php?p=2883023&postcount=13
nismaratwork said:edit: To be fair, ANFO can do a lot of damage (Oklahoma City)... a pony nuke or dirty bomb would be FAR worse, economically, psychologically, and practically. The cleanup... oh man.
FlexGunship said:Well, there's the question of intentional damage and unintentional damage. History has shown that there is much more intentional damage done by misuse of oil. Additionally, history has shown that there it much more unintentional damage done by oil. The same is true of coal.
Oddly, no one has found a way to misuse solar power to cause damage... or have they?

FlexGunship said:Not to be overly utilitarian, but if you're discussing the dangers of power generation (which is not the purpose of the thread) shouldn't you count it in terms of watt-hours per death. Obviously, higher would be better! More power with fewer deaths.
Since I invented the unit, I'd like to call it the "toasty" (symbol is the Jesus fish, ichthys).
-Wind is pretty bad at 6.66 teratoasties.
-Rooftop solar is horrible at 2.27 teratoasties.
-Hydro is okay if you ignore Banqiao (the Chernobyl of hydroelectric) at 10 teratoasties, but a crappy 0.71 teratoasties if you include it.
-Nuclear has the best ratio at 25 teratoasties if you INCLUDE Chernobyl. If you don't include Chernobyl then it has a rating of 1875 teratoasties. That's 1.875 petatoasties! (That number includes a single death that was attributed to radiological exposure of a plant worker. There is still debate over that.)
For comparison, coal is only 0.006 teratoasties, and oil is 0.028 teratoasties.
Banqiao was responsible for 26,000 deaths directly, and 150,000 from famine and disease after. Chernobyl was responsible for 56 deaths directly and 19 more later were attributed to it. I vote we stop talking about Chernobyl entirely, forever, in the context of nuclear safety. It essentially works out to a rounding error for coal or oil.

BobG said:Or a simple truck spraying oil on dirt roads to eliminate dust.
This is an image of the Route 66 State Park in Missouri. If you look close, you'll notice the trees seem to grow in lanes. That's because the park used to be a small city called Times Beach. The lanes are the old dirt roads that had to be oiled to keep the dust down.
The person hired to do the oiling was a guy named Russell Bliss. Aside from hauling waste and oiling roads, he also subcontracted with a company called IPC to dispose of some of their waste. ICP was being paid $3,000 a load to haul toxic waste from a chemical company called Northeastern Pharmaceutical and Chemical Company and they would then turn around and pay Bliss $100 a load to dispose of it.
He disposed of it by mixing it with the oil he used to spray roads, stables, etc for miscellaneous customers, including the city of Times Beach. He dumped so much dioxin on the city roads that the federal government bought up the entire town, moved the residents, and then dug up a layer of topsoil, roads, etc to be incinerated.
Now the spot where the town used to be is the Route 66 State Park.
It doesn't take a terrorist - just some ignorant old guy that never finished high school that has no idea of what he's disposing of (of course, the fact that he mixed it with engine oil to dispose of it suggests he knew more than he ever admitted).

Sitting silent in their classroom, the 30 children whose parents have not come to collect them after tsunami swept away their town

Even amid the carnage and despair of Japan's tsunami victims, the plight of the 30 children at Kama Elementary School is heartbreaking.
They sit quietly in the corner of a third-floor classroom where they have waited each day since the tsunami swept into the town of Ishinomaki for their parents to collect them. So far, no one has come and few at the school now believe they will.
Teachers think that some of the boys and girls, aged between eight and 12, know their fathers and mothers are among the missing and will never again turn up at the gates of the school on the eastern outskirts of the town, but they are saying nothing.

A group of boys turns misfortune into good deeds by spearheading relief efforts for quake and tsunami victims.
A group of boys has taken it upon themselves to scavenge for food and supplies among the debris in Taro, where their village once stood.
They have been able to provide some relief to hundreds of survivors sheltered at a nearby Buddhist temple.
