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.

68 Year Old Fights off Samurai-Sword-Wielding Bandits With Bottle of Sherry

, , , ,

The Belfast Telegraph reports an unusual case of self defence in the United Kingdom.

A grandfather today told how he fought off masked men wielding Samurai swords as they tried to rob his post office.

The two balaclava-wearing intruders took turns at slashing Alan Garratt with the three-foot long weapons at the Leicestershire branch, he said.

But they fled empty-handed after the 68-year-old, who had previously undergone surgery for a triple heart bypass, fought back with a sherry bottle.

The raid was captured on a CCTV camera, which was installed after a burglary at the post office, in Knipton, Leicestershire, just days earlier.

Mr Garratt needed eight stitches in his left arm after Monday evening’s attack.

He told the Leicester Mercury: “I don’t think they thought anyone would tackle them.

“I didn’t really feel it when I was cut on the arm and hand until afterwards. There was blood everywhere.

“The only thing I could find to arm myself with was a bottle of sherry.

Home Defense With Katana

,

The NRA’s Armed Citizen column in American Rifleman has for many years published accounts of successful cases of self defense with firearms. But how often do you read a story of someone defending his home with a samurai sword?

Muncie Star Press:

Muncie man is in jail with samurai sword injuries after allegedly breaking into another man’s home to get his wife back.

Joseph M. Hartman, 28, and his friends Bobby Joe Overbay, 18, and Matthew Michail Wilson, 23, all from Muncie, broke into the home of Jessy Mann, 26, 1910 S. May Ave., early Saturday morning to “take Hartman’s estranged wife by force,” according to the Muncie Police Department.

In a telephone interview on Saturday, Mann gave this version of the incident:

The three men knocked at the door and refused to leave when Mann asked them to do so. Then they entered the home and began throwing objects at him, including an alarm clock and furniture. Mann grabbed a collectible sword to defend himself and swung at the three men, hitting Hartman in the head and chest and Overbay in the forehead.

“It was crazy,” Mann said. “It was like something you would see in a movie.”

At one point, Mann said Hartman found his wife, from whom he is separated, in the bedroom calling the police, and he grabbed her by the hair.

“They were saying ‘Just let us take her, just let us take her.’ I was like ‘You ain’t taking nobody from my house,” Mann said.

Hartman and his friends left the home without his wife. Before fleeing, they got into a Jeep Cherokee and ran into the house three times and then drove away.

The police arrested the suspects and took them to Ball Memorial Hospital before booking them into the Delaware County Jail with no bond. …

Mann said he never intended to use the sword as a weapon and he was glad no one was killed.

“I just like swords,” he said. “I just have them around for novelty. I never expected I’d have to do some crazy stuff like that.”

Tameshigiri (Senbongiri)

, , , , ,

Circulating in martial arts circles this morning are a pair of videos from Japanese television of an attempt by someone whose name I couldn’t catch trying to make his mark in the Guinness Book of Records in Tameshigiri, the cutting with a sword of makiwara (targets) made from tatami (rush floor mats) rolled around a bamboo shaft.

The particular feat being attempted is Senbongiri, 1000 cuts in as short a time as possible.

Katsujin-ken Satsujin-to

, , , , , ,

Dan Simpson‘s editorial is an unfortunately typical expression of the excessive and exaggeratedly phobic attitudes of members of our over-domesticated, metrosexual intelligentsia toward firearms.

Guns are regarded as detestable and intrinsically dangerous objects which need to be kept under official control at all times, ideally in bank vaults. Their complete removal from American society is so unquestionably desirable that even house-to-house searches, and the shredding of the Bill of Rights, would be a perfectly acceptable price.

Obviously, this kind of policy proposal represents not a practical response to a real problem, but rather an irrational and emotional outburst, indifferent to benefits and costs, oblivious to process and law, expressive of an overwhelming combination of fear and aversion so profound as to dispense completely with practicality, proportionality, and cause and effect.

This kind of hostility toward firearms, this hoplophobia, needs to be recognized as the kind of irrationalism that it is.

In a sane society, familiarity and skill with arms, possession of the ability to defend oneself and others would be looked upon as essential components of every man’s education.

In dojos offering training in kendo and aikido, the following phrase written in the grass script on a scroll is commonly hung for purposes of admonition and inspiration.

These Japanese radicals are pronounced Katsujin-ken Satsujin-to (sometimes, Katsujinken satsujinken) meaning “The sword which kills is the sword which gives life.”

They are often rendered more explicitly in English as “The sword which cuts down evil is the sword which preserves life.”

This adage is attributed to the masters of YagyÅ« school, the Tokugawa shoguns’ personal instructors in swordsmanship.

And those Yagyū school sword sensei-s were right. The rightful use of weapons is essential in an imperfect world to defend innocent lives against unjust violence.

A wider commitment to skill at arms and a more common readiness to defend the innocent would be infinitely more effective at saving the lives of victims of attacks by madmen and criminals than a totalitarian program attempting to enforce universal disarmament.

Katsu-tempo satsu-tempo.

At Virginia Tech, a gun in the hands of the right bystander could have been the gun which destroyed evil and the gun which preserved life.

Japanese Sword Cutting Bottle

It’s very short and has no sound track, so I was not going to blog it, but everyone who has seen it seems to love this video of a Japanese sword slicing through a plastic bottle. Sharp, isn’t it?

Closing Down This Year’s Dai Token Ichi (Great Japanese Sword Show)

,

Close of 19th Dai Token Ichi (leading Japanese Sword Show) held October 27-29, 2006 at the Tokyo Bijutsu Club – Pt. 1 – 2:57 video — Pt. 2 – 0:51 video

Yes, it’s just a pair of videos of the Japanese dealers packing up their merchandise at the show’s end in preparation for departure, but we didn’t get to go this year, and it is intriguing for Nihonto enthusiasts to catch even a glimpse of the swords offered for sale at this event.

Aotsu Yasutoshi Collection Exhibition

, , ,


Aotsu Yasutoshi (1893-1984)

Mr Richard Turner, one of Australia’s leading Nihonto collectors and authorities, has started a blog (Tosogu.com) devoted to the discussion of Japanese sword furniture which will undoubtedly prove of great interest to collectors and connoisseurs.

The first posting announces the exhibition at the Sukagawa City Museum in Fukushima of the collection of the tosogu (Japanese sword furniture) of the late Aotsu Yasutoshi, who left an extraordinary collection, assembled over seventy years of collecting, including some 420 tsuba (swordguards) of extremely high quality and aesthetic interest.

The current exhibition is available on-line. There is no translation, but the viewer needs only to click on the left/right arrows to navigate the site.


Ko-Katchushi (Armor-maker made) tsuba, probably mid-Muromachi (c. 1392-1467 AD) – design motif: snowflakes
