Tsunami, Japan
-
That was a terrible event. Hopefully the Japanese people will have the strength to recover from this disaster.
-
My daughter was scheduled to fly home the day after the earthquake, and my brain turned to mush after her email message that she was at a subway station, and transit halted. Thereafter her phone system went down.
-
I am wishing for the best that she is safe with friends, and that communications can be restored, soon.

MY PRAYERS FOR YOUR DAUGHTERS SAFE RETURN

Hope you get good news soon.

Be strong and may she return quickly and safely to her home.

From the station, she walked to her hotel (subway was down). The day of her flight, her bus to the airport was canceled (she thinks broken roads), and she had to catch a train. Because of the train's route, it took longer to get to Narita, and she missed her flight. She camped out at the airport waiting for the next flight. Only good thing was that her Japanese cel came on line and she was able to email me. My daughter is a triple
Dragon. Her Grand Mother, and Mother were born under the same sign. What are the odds for that. Anyway, she got a seat on United 880, 24 hours later without a reservation. How lucky can you get.Her father, me, can now think logical about the threat of reactor radiation. Can I?

When I was about 15, a Tsunami swept through Hilo, Hawaii, the small town I lived in. I remember waking up to the sound of explosions, and the flash of fireworks outside. My first thought, "I am missing the 4th again", and ran to the back door. In the dim of the night I saw a red house where a white one use to be.
It's a vision forever etched in my mind.

Oh man. I really hope that everything works out okay for you.
My best friend Richard (and godfather of my two daughters) works and lives in Tokyo. Damage there apparently is minimal (thanks to the Japanese attention to structural detail in an earthquake zone). The real problem there is lack of transport and 3-hour powercuts everyday. If she's not near the affected northern coast, she's probably fine.
Also you need to remember, when it comes to nuclear power, the Japanese are amongst the most advanced at it in the world. Russia at the time was on the brink of the collapse of the Soviet Union. There was absolutely no investment into the power stations at Chernobyl. Japan on the other hand is one of the worlds richest countries, so they do have the infrastructure to rebuild their country- although it's going to take some time. They of course have the dual experiences of both Hiroshima and Nagasaki, I don't think they would take safety lightly.
So I really doubt that we are about to witness another Chernobyl 
You're probably being haunted more by your memories than the actual reality right now. Hang in there, it'll be okay.

I understand from current news reports that radiation leakage was minimal. However, any leakage is significant.
I am glad to see that your daughter has contacted you. -

My wife taught elementary school in Hilo and for awhile lived with a woman who had been in the Tsunami that hit in 1946. Even my wife's description of hearing about it made me shudder.
I'm glad your daughter is safe.

Alas radioactivity and fusion is now the first problem inside the all disaster!
At 200 kms on an amercicain aircraft carrier radioactivity's doses were so strong
that is must take back!
It was an absurdity to build over and near seismic fractures!
Radioactivity has no frontier!
We are all on the same bath!The second problem will be the next "big one"! There are now 200 kms of seismic plates not yet broken due the first!
That is really a true planetary disaster!
I hope for your familly, and all peole that will be secure!
Very darks days will come!

There is a significant difference, from what has been reported, between Chernobyl and Fukushima. They were unable to shut down the reactor at Chernobyl, whereas the The Japanese reactors have been shut down.When the earthquake occurred sensors cause safety mechanisms to automatically insert control rods into the reactor to halt the nuclear chain reaction. The fuel rods will still be physically and radioactively hot, and must be kept cool for ? (a week or so I have read and discussed). If they are not cooled, then the rods do actually "melt down",and release radiation.
The problems in Japan began when the Tsunami destroyed the diesel backup generators at the plant, forcing them to their battery backup which is only good for hours. If the level of water goes down, because pumps can't be kept up, and the rods are exposed to air, then they over heat, and when they are again flooded the zirconium sheathing around the rods will oxidize releasing hydrogen which builds up in the concrete containment building. This was probably ignited by sparks. They are now pumping seawater laced with boron into the reactors to cool them. The boron absorb neutrons released during the fission of Uranium. It is also a good part of the control rods used to shut down the reactors, and also helps to bring down the temperature.
The worst case scenario is a failure to keep cooling the rods which would cause them to melt and fall to the reactor containment vessel floor.
This is a boiling water style of reactor, and the criticism on this type of reactor is that there is a chance the rods could burn through the floor of the containment vessel. This is where the similarity to Chernobyl exists, because that is what happened there.
The difference is that Chernobyl had no containment vessel, and the core contained graphite, which when it burned sent the radioactive ash plume into the environment.
Therefore the prediction is, that if this should take place, radioactivity will be released into the environment, but would be much more limited than Chernobyl.
The argument rages over what this actually means, but since any radiation has serious health effects on the environment, and by extension, us, then....
What I wonder is, what was said at the high level meeting that decided on the location of this particular plant,(and who knows how many more).
I also often hear the assertion that we will be able to come up with Technology to deal with the carbon emissions we seem so free to deploy, and I wonder if we will ever learn that we can't out engineer nature. -
Hi,
I apologize for my English. Much of what I runs through my head is difficult fore me to express in the English language.
I have looked at the pictures of the tsunami. I found them fascinating and terrifying. It shows again how powerless the humans are against these elements.
What touched me the most is how many people have lost their lives there.
Even with the nuclear power plants was always stressed that they are safe. As one particularly in Japan, from experience, plans earthquake-safe.
There are no nuclear plants which have a hundred percent security. And the danger is not over. The people living there have to bear the consequences.
Even here in Germany nuclear power plants were built directly in an earthquake zone (Upper Rhine trench).
This shows that many events that are difficult or impossible to control. I hope again that people will become reasonable.
Charly

Yes, a tragical lesson one more time!

In Japan do they have a choice other than not to build nuclear power stations?

So this is a good analogy with all choices.
They made the choice. These are the consequences.
(Who are they? And why are they trusted with these choices? Who pays for their choices?) -
We must take risks! Think of all the good that has already been done.
Yes, this is a setback- and a big one too, but without risks, we will perish. I don't ever want to go there.

Someone said the other day that the deaths per kWh of electricity generation are minimal for nuclear power [even with Chernobyl] compared with hydroelectricity - where over the history of electricity generation the several 'burst dams' have killed many thousands !
However, I still think I'd prefer to be killed immediately in a flood than maybe die some months [or years] later from a radiation induced cancer...
BUT... actually I'd prefer not to die at all... or at least if I do die, to die at a time somewhat of my own choosing or action/inaction, and NOT at the whim of some grade-B engineer who fudged his calculations...
[I'm an expert too and I know how easy it is to convince yourself of your own infallibility - although I don't think anyone died from one of my Ruby scripts [YET!] [if so, see my lawyer!] ]

Yes : absolutly right!
but ...what is the life of radioactive waste in years?
We give a wonderland to our children!
Open your eyes! And mind!
