Pshaw! They made these back in the 1990s, so surviving examples (in original boxes) are probably going for high prices to collectors on Ebay Japan.

Still, there is something spectacularly Japanesedly-perverse (and highly un-PC) in the concept of a toy allowing the small fry to learn to play Russian Roulette.

All-Time Expensive Traffic Pile-Up

, , ,


Sunday: Dead Ferraris all over the Chugoku Expressway in Shimonoseki, southwestern Japan.

8 Ferraris, a Lamborghini, three Mercedes Benz, and two Toyotas, a total of 14 vehicles bought the farm when one Ferrari driver trying to change lanes lost control, bounced off a barrier, and came spinning back into the middle of a luxury car caravan heading for an enthusiasts’ event in Hiroshima.

No one, besides the automobile insurance company executives seen leaping from high windows, was seriously injured in the accident, but a lot of very expensive metal was seriously bent.

Japanese Man Performs Solo Rescues

, , ,


Hideaki Akaiwa

The exploits of one Japanese man who took the job of rescuing his wife and mother into his own hands are being celebrated widely on the Web today.

The LATimes version:

Whereas many Japanese have adopted the nation’s unofficial mantra: Shou ga nai, or, more politely, Shikata ga nai, loosely translated as, “What can you do?,” “It’s beyond our control” or “It’s out of my hands,” [Hideaki] Akaiwa stands out as a virtual live-action hero.

Akaiwa said he was at work a few miles away when the tsunami hit, and he rushed back to find his neighborhood inundated with up to 10 feet of water. Not willing to wait until the government or any international organization did, or did not, arrive to rescue his wife of two decades — whom he had met while they were surfing in a local bay — Akaiwa got hold of some scuba gear. He then hit the water, wended his way through the debris and underwater hazards and managed to reach his house, from which he dragged his wife to safety.

“The water felt very cold, dark and scary,” he recalled. “I had to swim about 200 yards to her, which was quite difficult with all the floating wreckage.”

With his mother still unaccounted for several days later, Akaiwa stewed with frustration as he watched the water recede by only a foot or two. He repeatedly searched for her at City Hall and nearby evacuation centers.

Finally, on Tuesday, he waded through neck-deep water, searching the neighborhood where she’d last been seen. He found her, he said, on the second floor of a flooded house where she’d been waiting for help for four days.

“She was very much panicked because she was trapped with all this water around,” Akaiwa said. “I didn’t know where she was. It was such a relief to find her.”

A more colorful (and profane) account lists him as Badass of the Week.

Reactor Containment Chambers and Samurai Swords

, , , , , ,

George Monbiot (the original moonbat), the very last person in the world whom you would ever expect to become pro-nuke, says that events in Fukushima have caused him to stop worrying and love nuclear power.

You will not be surprised to hear that the events in Japan have changed my view of nuclear power. You will be surprised to hear how they have changed it. As a result of the disaster at Fukushima, I am no longer nuclear-neutral. I now support the technology.

A crappy old plant with inadequate safety features was hit by a monster earthquake and a vast tsunami. The electricity supply failed, knocking out the cooling system. The reactors began to explode and melt down. The disaster exposed a familiar legacy of poor design and corner-cutting. Yet, as far as we know, no one has yet received a lethal dose of radiation.

—————————————

The effectiveness of the containment at Fukushima is based on single-piece steel containment chambers, built by Japan Steel Works, (株式会社日本製鋼所, Kabushikigaisya Nihon Seikōsho), a steel manufacturer founded in Muroran, Hokkaidō, Japan in 1907, which traces its technological heritage directly back to the native Japanese steel-making tradition which produced the Japanese samurai sword.

Justin Hyde:

As fears rise in Japan about nuclear disaster at the Fukushima plant, the first and best line of defense are the reactor’s six inch thick steel-walled chambers, made by a company that still forges samurai swords by hand.

Japan Steel Works is the world’s only volume builder of nuclear reactor vessels, the steel container that holds radioactive fuel, and in case of a meltdown, prevents that fuel from leaking and triggering a catastrophe. Founded in 1907 and rebuilt following World War II, it supplied nearly all of the vessels used in Japan’s 54 nuclear power plants, including the containers at the Fukushima Daiichi plants designed by General Electric and Toshiba.

While those vessels were made from steel plates bolted and welded together, modern designs require Japan Steel Works to forge containers from a single ingot that can weigh up to 600 tons. It’s a slow process that takes months at a time, using the company’s 14,000-ton press to shape a special steel alloy that’s been purified to maximize its strength. These methods also minimize seams that can give way in case of a meltdown, where nuclear fuel can reach 2,000 degrees Celsius.

Although Japan Steel Works is a major corporation with 5,000 employees, it also maintains a samurai sword blacksmith, in a small shack on a hill above the factory in Muroran, where a single craftsman still hammers steel into broadswords, as the company has done since 1917.

—————————————

Japan Steel Works founded its smithy in 1918 by recruiting Taneaki Horii, whose teacher Taneyoshi Horii (c. 1820-1903), had studied under Gassan Sadayoshi (1800-1870), founder of the Osaka Gassan school, and under Taikei Naotane (c. 1777-1857).

Naotane was himself the pupil of Suishinshi Masahide (1750-1825) of Edo, the founder of the Shinshinto (New Revival) period of sword-making. Masahide criticized the showiness and practical defects of the Shinto sword, and advocated the building instead of the fukko-to, “the Restoration sword,” by returning to the sword-making techniques and styles of the Heian and Kamakura periods.

MIT Scientist: Fukushima Came Close to Meltdown, But Did Shutdown Safely

, ,


Nuclear power plant explosion at Fukushima

CORRECTION: Yesterday’s original photograph (found at Business Insider) was actually a natural gas facility at Chiba, not the Fukushima reactor. Thanks to K for catching this.

Ignore the screaming headlines on Drudge produced by the mainstream media. Josef Oehmen, an MIT research scientist with a doctorate in Mechanical Engineering, explains that the operators of the Japanese nuclear power plant at Fukushima were very unlucky and suffered a hydrogen gas explosion. It came close to the limits of its safety design, but did actually remain within them.

I am writing this text (Mar 12) to give you some peace of mind regarding some of the troubles in Japan, that is the safety of Japan’s nuclear reactors. Up front, the situation is serious, but under control. And this text is long! But you will know more about nuclear power plants after reading it than all journalists on this planet put together.

There was and will *not* be any significant release of radioactivity.

By “significant” I mean a level of radiation of more than what you would receive on – say – a long distance flight, or drinking a glass of beer that comes from certain areas with high levels of natural background radiation.

I have been reading every news release on the incident since the earthquake. There has not been one single (!) report that was accurate and free of errors (and part of that problem is also a weakness in the Japanese crisis communication). By “not free of errors” I do not refer to tendentious anti-nuclear journalism – that is quite normal these days. By “not free of errors” I mean blatant errors regarding physics and natural law, as well as gross misinterpretation of facts, due to an obvious lack of fundamental and basic understanding of the way nuclear reactors are build and operated. I have read a 3 page report on CNN where every single paragraph contained an error. …

At some stage during this venting, [an] explosion occurred. The explosion took place outside of the third containment ([the] “last line of defense”), and the reactor building. Remember that the reactor building has no function in keeping the radioactivity contained. It is not entirely clear yet what has happened, but this is the likely scenario: The operators decided to vent the steam from the pressure vessel not directly into the environment, but into the space between the third containment and the reactor building (to give the radioactivity in the steam more time to subside). The problem is that at the high temperatures that the core had reached at this stage, water molecules can “disassociate” into oxygen and hydrogen – an explosive mixture. And it did explode, outside the third containment, damaging the reactor building around. It was that sort of explosion, but inside the pressure vessel (because it was badly designed and not managed properly by the operators) that lead to the explosion of Chernobyl. This was never a risk at Fukushima. The problem of hydrogen-oxygen formation is one of the biggies when you design a power plant (if you are not Soviet, that is), so the reactor is build and operated in a way it cannot happen inside the containment. It happened outside, which was not intended but a possible scenario and OK, because it did not pose a risk for the containment.

So the pressure was under control, as steam was vented. Now, if you keep boiling your pot, the problem is that the water level will keep falling and falling. The core is covered by several meters of water in order to allow for some time to pass (hours, days) before it gets exposed. Once the rods start to be exposed at the top, the exposed parts will reach the critical temperature of 2200 °C after about 45 minutes. This is when the first containment, the Zircaloy tube, would fail.

And this started to happen. The cooling could not be restored before there was some (very limited, but still) damage to the casing of some of the fuel. The nuclear material itself was still intact, but the surrounding Zircaloy shell had started melting. What happened now is that some of the byproducts of the uranium decay – radioactive Cesium and Iodine – started to mix with the steam. The big problem, uranium, was still under control, because the uranium oxide rods were good until 3000 °C. It is confirmed that a very small amount of Cesium and Iodine was measured in the steam that was released into the atmosphere.

It seems this was the “go signal” for a major plan B. The small amounts of Cesium that were measured told the operators that the first containment on one of the rods somewhere was about to give. The Plan A had been to restore one of the regular cooling systems to the core. Why that failed is unclear. One plausible explanation is that the tsunami also took away / polluted all the clean water needed for the regular cooling systems.

The water used in the cooling system is very clean, demineralized (like distilled) water. The reason to use pure water is the above mentioned activation by the neutrons from the Uranium: Pure water does not get activated much, so stays practically radioactive-free. Dirt or salt in the water will absorb the neutrons quicker, becoming more radioactive. This has no effect whatsoever on the core – it does not care what it is cooled by. But it makes life more difficult for the operators and mechanics when they have to deal with activated (i.e. slightly radioactive) water.

But Plan A had failed – cooling systems down or additional clean water unavailable – so Plan B came into effect. This is what it looks like happened:

In order to prevent a core meltdown, the operators started to use sea water to cool the core. I am not quite sure if they flooded our pressure cooker with it (the second containment), or if they flooded the third containment, immersing the pressure cooker. But that is not relevant for us.

The point is that the nuclear fuel has now been cooled down. Because the chain reaction has been stopped a long time ago, there is only very little residual heat being produced now. The large amount of cooling water that has been used is sufficient to take up that heat. Because it is a lot of water, the core does not produce sufficient heat any more to produce any significant pressure. Also, boric acid has been added to the seawater. Boric acid is “liquid control rod”. Whatever decay is still going on, the Boron will capture the neutrons and further speed up the cooling down of the core.

The plant came close to a core meltdown. …

The plant is safe now and will stay safe.

Japan is looking at an INES Level 4 Accident: Nuclear accident with local consequences. That is bad for the company that owns the plant, but not for anyone else.

Some radiation was released when the pressure vessel was vented. All radioactive isotopes from the activated steam have gone (decayed). A very small amount of Cesium was released, as well as Iodine. If you were sitting on top of the plants’ chimney when they were venting, you should probably give up smoking to return to your former life expectancy. The Cesium and Iodine isotopes were carried out to the sea and will never be seen again.

There was some limited damage to the first containment. That means that some amounts of radioactive Cesium and Iodine will also be released into the cooling water, but no Uranium or other nasty stuff (the Uranium oxide does not “dissolve” in the water). There are facilities for treating the cooling water inside the third containment. The radioactive Cesium and Iodine will be removed there and eventually stored as radioactive waste in terminal storage.

The seawater used as cooling water will be activated to some degree. Because the control rods are fully inserted, the Uranium chain reaction is not happening. That means the “main” nuclear reaction is not happening, thus not contributing to the activation. The intermediate radioactive materials (Cesium and Iodine) are also almost gone at this stage, because the Uranium decay was stopped a long time ago. This further reduces the activation. The bottom line is that there will be some low level of activation of the seawater, which will also be removed by the treatment facilities.

The seawater will then be replaced over time with the “normal” cooling water.

The reactor core will then be dismantled and transported to a processing facility, just like during a regular fuel change.

Fuel rods and the entire plant will be checked for potential damage. This will take about 4-5 years.

The safety systems on all Japanese plants will be upgraded to withstand a 9.0 earthquake and tsunami (or worse).

Latest Problem Attributable to Global Warming

, ,

The Japanese earthquake and consequent tsunami!

Christopher Mims has the word from prominent druids and witchdoctors experts.

So far, today’s tsunami has mainly affected Japan — there are reports of up to 300 dead in the coastal city of Sendai — but future tsunamis could strike the U.S. and virtually any other coastal area of the world with equal or greater force, say scientists. In a little-heeded warning issued at a 2009 conference on the subject, experts outlined a range of mechanisms by which climate change could already be causing more earthquakes, tsunamis, and volcanic activity.

“When the ice is lost, the earth’s crust bounces back up again and that triggers earthquakes, which trigger submarine landslides, which cause tsunamis,” Bill McGuire, professor at University College London, told Reuters.

Melting ice masses change the pressures on the underlying earth, which can lead to earthquakes and tsunamis, but that’s just the beginning. Rising seas also change the balance of mass across earth’s surface, putting new strain on old earthquake faults, and may have been partly to blame for the devastating 2004 tsunami that struck Southeast Asia, according to experts from the China Meteorological Administration.

Even a simple change in the weather can dramatically affect the earth beneath our feet.

I thought I had a new one for Warmlist, but “earthquakes” was already on the list, from as far back as 2004 citing NASA no less.

The problem with the application of the glaciers-melting-and-lightening-the-load-so-up-pops-the-tectonic-plate theory in this case is that no melting glaciers are located on the ocean bed of the Pacific east of Honshu, Japan.

Edo-Period Japan Still Present Today


Suzuki Harunobu, Title Unknown, woodblock print, c. 1768.

Henry Tricks, the Economist’s Tokyo bureau chief, finds Japan’s Edo-period past “shimmering just below the surface of modernity.”

It is mid-September, the heat is just leaking out of the end of summer, and Japan is enjoying a rare public holiday. A holiday, that is, in the uniquely Japanese sense of the word, which means the GPS hardwired into every citizen is sending thousands upon thousands to the same fashionable boutiques near my home in Tokyo to shop. It is more crowded than a commuter train at rush hour. Policemen shepherd the multitude along the streets with flashing orange batons. Yet there is something peaceful about the way the Japanese drift together in a crowd; they carry a tiny aura of personal space with them, no bigger than one of their Louis Vuitton handbags, and every bit as precious. They hardly touch, like those shoals of translucent fish that dart from one direction to another without colliding. The policemen use their batons like conductors, keeping everything harmonious. But if you try to defy them, those batons will block your way faster than they can say “Dame desu”—which is about as final as “Not on your life.”

Such are the means by which order and harmony are maintained in Japan. There is a deep-rooted respect for others, so ingrained that ground staff at Narita airport bow to departing planes as they taxi to the runway. And there is a subtle coercion, like an invisible hand on society’s collar, based on centuries of ancestor worship that has made many customs immutable. The attitudes have been shaped partly by the physical landscape of Japan, which packs one of the most crowded populations on earth onto narrow plains, bounded by sea and inhospitable mountains. For centuries the main activity has been rice farming, which requires communal planting, weeding, watering and harvesting, rather than the rugged individualism of American and European agriculture.

I have been mesmerised by life here since I arrived a year ago, floating on a wave of adoration of most things Japanese, yet getting in everyone’s way and doing everything wrong. I would jog around the Imperial Palace in a clockwise direction, only to find everyone else running anti-clockwise, bearing down on me as if I didn’t exist. I wore short sleeves in early autumn, and couldn’t work out why, when it was still blazing hot outside, everyone had put on their jackets and ties again. After swimming with dolphins on the island of Mikurajima this summer, my family and I went to a café to have lunch, still in our damp bathing costumes. Our hostess was so livid that at first I thought we must have set the place alight, not left a few damp seats where our bottoms had been. Living as a foreigner in Japan, for all its attractions, has many such small humiliations. You may be on a noble quest to plumb the depths of the Japanese soul, but you will take so many wrong turns you end up wondering whether you are indeed too brutish to make sense of it.

You may also be struck by how few of the locals have a matching interest in you and your culture. That is because it increasingly seems as if the outside world—with its sharper elbows, fattier food and shoddy dress sense—is kept at arm’s length. Fewer young Japanese are travelling abroad, fewer are studying English (this year, the main English-language school went bust), and fewer are taking places at leading academic institutions overseas such as Harvard Business School. Bosses at Japan’s legendary export businesses complain they cannot find youngsters who are prepared to work abroad. Two clever young Japanese friends, just posted to excellent jobs in America, told me that Japan is so comfortable they find it hard to leave.

Yet as those friends are the first to admit, it is a cotton-wool comfort that keeps out alien germs–like the surgical facemasks that many Japanese wear, so at odds with the rest of their perfect attire. To the outsider, it can lend the society an air of feeble vulnerability. At times it is downright maddening. Foreign ATM cards don’t work in most Japanese banks, Japanese movies—even the classics—rented at the ubiquitous Tsutaya video store don’t offer the option of foreign-language subtitles. Japanese mobile-phone technology is so idiosyncratic that analysts talk of “the Galapagos effect”, because it has grown up in a unique eco-system that makes it unsuitable for use anywhere else.

At times it feels as if the outside world does not exist. …

[I]t is the Edo era, the peculiar two-and-a-half-century time capsule from 1603 to 1868, that casts the longest shadow. It was the time when a newly unified Japan turned its back on the outside world, shut its borders to almost all foreigners, stopped its people travelling abroad and forbade Japanese émigrés from returning to the country on pain of death. Each person was given his exact rank in society–in descending order: samurai, farmer, craftsman, merchant and outsider—and Japan went for 265 years without wars or revolutions. Much of this era is known as the sakoku jidae or “closed-country period”, and it was centred on Edo, now Tokyo, while the emperor was cloistered in Kyoto. At first glance, it seems like the epitome of the dark ages—a medieval equivalent of North Korea or Pol Pot’s Cambodia, ruled by an all-powerful family of shoguns, or military dictators, named Tokugawa. They handed on power for 14 generations, and kept the citizens in line through a byzantine network of spies and informants. The execution grounds can still be visited in Tokyo. Ordinary criminals might be crucified, boiled, burned or chopped in half: only the lucky samurai got to disembowel themselves.

The gore, of course, has gone, but it seems to me that something of the Edo era shimmers just below the surface of modern Japan.
