Massive Earthquake and Tsunami strikes Japan

Looks like nuclear scientists are mostly unemployed nowadays. They spend a lot of time posting their knowledge and advices for their colleagues to see, but on video games forums...
 
The problem is that the mass of nuclear material in a power plant dwarfs the mass of nuclear material in a bomb. Spread it around and there's a great deal more radiation and heavy metal poisoning.
Underlined part wrong. There would be more heavy metal poisoning--and less radiation. Because what's producing the radiation is the fact that the fuel rods are in close proximity to one another. Separate the fuel rods and the radiation goes down.
 
Great new article from Reuters: Special Report: Mistakes, misfortune, meltdown: Japan's quake.

US monitoring resources has arrived in the air above Fukushima.

msnbc said:
NBC's sources said the Japan nuclear site and its surroundings are being monitored by a variety of U.S. aircraft, including:

* U-2 spy planes. The U-2s, flying out of Okinawa, have "radiation suites" that can take readings at various altitudes.
* Global Hawk drone.The Global Hawk remote-controlled plane, now on its second run, has multispectral imaging capabilities, including thermal infrared and synthetic aperture radar. Kyodo News Service quoted Japanese government sources as saying that the Global Hawk was taking images of the inside of the reactor buildings.
* WC-135 Constant Phoenix aircraft. One radiation-sniffing WC-135, basically a converted Boeing 707 jet, is on its way from Offutt Air Force Base in Nebraska to the area around Japan, where it will take atmospheric readings.

Clearly a big admission from Japan to allow these resources into 'their' operation. And frankly a great relief to see them admitting that they could use the assistance.
 
I think that's part of the Japanese psyche. They screwed up (or at least didn't succeed, which is just as bad), so now they will humble themselves, ask for help, but the shame will make them ensure that they never screw up like this again. Admirable traits, really, if the morality did not also traditionally include ritual suicide.

So Christians with a tendency to disembowel themselves?
 
Think again.


Communications are severely impaired in ALL earthquakes. Underground cables get snapped by shifting rock, above-ground cables get snapped when the telephone poles fall over, cell phones go offline when the cell towers topple. Plus, whatever networks remain operational tend to get overloaded and crash when millions of people make phone calls at the same time trying to reach loved ones.

So, yes. Japan in 2011. Infallible technology is a fantasy incurred from watching too much Star Trek.

The explosions in question happened a couple days later. Do you honestly think they wouldn't have at least one phone line between the Prime Minister and the company reponsible for the plant by that point? Furthermore, if there wasn't a line up yet, why would the Prime Minister be mad that they didn't call him? If they were unable to call him, he should know that.
 
How's the situation going with the survivors of the tsunami and earthquake? While the nuclear issue is important, I'm beginning to feel that the press is starting to not give enough coverage of the growing humanitarian crisis with the survivors, because you basically have hundreds of thousands of people with dwindling supplies.
 
Why don't we take the fuel rods and push them somewhere else?

I vote for China. :D

I always liked the Japanese people. Their culture fascinates me, and their conduct during this unprecedented disaster impresses me. I've always found myself rooting for them. And they are our best friend in Asia. We should do everything we can to help them.

Look at the pictures in this link. There little statue of liberty replica kind of touched my heart in a way. I'm not sure why.

Good article. I'm especially amazed and depressed at how those schoolkids are just sitting there calmly while they probably are beginning to understand that their parents are most likely dead, and how everyone else is trying so hard not to give them any false hope. I've seriously now have more respect for Japanese culture now. It must be very, very hard.
 
Punch Q & A on Japan and the nuclear disaster

The Punch put some questions to one of the nation’s nuclear experts - Dr Gerald Laurence. Dr Laurence is a Radiation Safety Adviser and an Adjunct Associate Professor at the University of Adelaide’s School of Chemistry and Physics.

Q) How scared should people in Japan be about the nuclear situation?

A) Not a great deal – the 20-year total of deaths from Chernobyl (from the UN 20-year report) suggests that the radiation related deaths are of the order of a few thousand at most; of the thyroid cancers, mostly in the young 99 per cent were treated & cured (note all the data in the report are strongly disputed by environmental and progessive groups who claim that WHO & IAEA are under the influence of the nuclear industrial complex).

In Japan so far it is spent fuel rods that were removed from the core in November, so iodine-131 (which has an eight-day half life) is not a major risk. The most serious fission product that will be released will be caesium-137 with a 30-year half life.

The possibility of food (rice, milk, etc.) being contaminated because of contaminated fields is real, but public health measures (testing and so on) should mean such produce should not reach the public. Local contamination (houses, towns) will clear at rates dependent on the weather (dissolved in rain, etc.). Local weather also disperses & dilutes the plume (and I assume the Japan Met Bureau can model this very well).

Q) How scared should people outside Japan be?

A) South of the equator – not at all. Air transfer across the equator at sub-stratospheric heights is very slow. Northern hemisphere – the contamination will travel west to east with the normal weather pattern cycles of highs & lows, (it will not reach the jet stream) which means dilution and days for transfer. Levels in North America & Europe will be much less than in areas adjacent to Chernobyl.

Q) Do you think this disaster should be thought off as a once-off occurrence or a chance to rethink nuclear?

A) It depends on your views on risk assessment and risk-benefit analysis. This quake (and tsunami) was possibly the worst ever in Japan – a one in 1000 year or more event. Now we might re-design to cover such an event, but that it could be covered I have no doubt. This was not an immediately human-induced failure like Chernobyl, but design elements that were insufficient to accommodate the extreme natural events.

Q) Are there many misunderstandings in the public about the situation and if so, what’s the biggest?

A) Some misunderstandings about radiation risk are long standing, some currently due to misinformation (see USA Surgeon-General urging people to take iodine supplements, so there is reportedly not an iodine-tablet to be found in some states.[The point here is that iodine to be effective must be taken within a small window of time before exposure to iodine-131. It does not offer general “protection against radiation (see stories of Chinese buying up iodised salt!) and as I suggested above iodine-131 may be only a small component of the contamination mix.

Use of words like “radiation leaking from ...” – radioactive material (contamination) may “leak” – that distinction and the ones about doses and dose rates, scales of comparison and so on are unfortunate, and linked to the long-established public fears of radiation (compared with other harmful materials and exposures).

Q) How do you think this will influence the nuclear power debate in Australia?

A) It will be seen by the opponents of nuclear power as another powerful (pun!) argument against an Australian power program and against uranium exports (racism has shown up in statements from extreme elements such as “if this happens in Japan how much worse it will be in India”). I would prefer a situation in which the public could properly understand all sorts of risks but that is an idealist position.

Q) Reports from Japan have been conflicting – do you think this is intentional obfuscation or a result of the changing situation on the ground?

Probably a mixture of both (here in Oz we know that we can have conflicting reports on matters from leading members of governments of whatever political type!).

Analysis of the “obfuscation index” needs an expert on Japanese politics, the relationship between Tokyo Electric & the regulatory body, the smooth moves of civil servants from regulator to corporate positions, etc. On the ground measurements are not easy, interpretation probably even more difficult (not just total quantities of fall-out per hectare but the detailed nuclide (isotopic) composition etc.)

Q) What is the best case scenario? What is the worst case scenario?

Best case: Spent fuel rods recovered with water quickly, good meteorological conditions limit immediate spread, and people can deal with the tsunami/quake after-effects. Sadly the world has largely forgotten the thousands dead and selfishly, if understandably, concentrated on “how will I be affected”.

Worst case: Spent fuel rods cannot be water covered; spent fuel from the other reactors become involved, increasing the size of fallout contamination. A nuclear fission driven excursion like Chernobyl is not probable (different design, etc.). Real bad case – long-term psychological damage to the locals, bad enough following Chernobyl, but now with tsunami added. Perhaps the different social traditions between Ukraine & Japan will lead to a different community outcome. I hope so.

People, there is absolutely zero chance for this to be as bad as Chernobyl. It's a completely different reactor design in a country with a completely different political landscape with a completely different cause.
 
We're not worried about the reactors, we're worried about those spent fuel rods in that pool right now. I think the reactors will be okay.
 
The thing is, the more time passes, the less likely a meltdown will occur. Each passing second means more the of rod's energy is dissipated, more of Japan's infrastructure is put back online, and more information is provided to the people on the field. If a meltdown was gonna happened, it was most likely right after the cooling systems failed.
 
How's the situation going with the survivors of the tsunami and earthquake? While the nuclear issue is important, I'm beginning to feel that the press is starting to not give enough coverage of the growing humanitarian crisis with the survivors, because you basically have hundreds of thousands of people with dwindling supplies.

The situation is quite bad, I'd say even much worse than that of the people living close to the plants.
Most of these people are now homeless and live, when they can, in community centers, schools or such, with few food and clothes. Basic infrastructure (for electricity, roads...) is slowly built back, but it takes time. Beside, snow came back recently along with cold...

Yeah, that's basically what the news has been saying if it mentions it at all. (And I guess now that the nuclear panic is dying down a bit, they're starting to talk about it again?) I wish I could go around pointing fingers against someone, but the infrastructure is pretty screwed up anyways that it makes it difficult for anything to be rebuilt and for supplies to be delivered.
