    The BWR/6 reactor operating manuals from GE have been on the internet since March 2011. There is no mention of total electrical failure in them either, emergency power is assumed to be available, which did not happen. They also assumed that due to design for seismic activity, coolant pipes to the reactor vessel would remain intact following an earthquake, which did not happen according to workers on site at the time.

    Lots of assumptions...too many for my liking.

    Perhaps they can compare wasabi vs. natto next?

    @ubikwit - GM sold it's stake in Subaru to raise cash, and Toyota bought some of it. Subaru make Camrys for them at their Indiana factory, giving them more work at a loss-making plant. They were also interested in Subaru's boxer engine, drive train and other technologies for the proposed Toyobaru FT86 sports car, a successor to the AE86. Subaru also got the marketing for the appalling DEX, a sort of sporty Kei Car based on the Toyota bB and Daihatsu COO/ Materia minicar.

    @marcels - maybe people are just sick of sport tournaments and their expensive tickets? Just a never-ending stream of baseball/ tennis/ golf/ olympics/ football/ athletics/ world cups/ paralympics/ asian games/ commonwealth games/ etc.. With the same media companies/ corporate sponsors/ drink and shoe companies advertising everywhere in the hope that people will buy their products, while the execs look on from their air-conditioned VIP boxes and limousines...

    More business for the Foreign Buyers Club of Kobe, who also cater to those who crave home foods, and can't read the local labels.

    @willib - JAL 123 from Haneda to Itami never flew upside down, but it had to steer using it's engine thrust as it was missing the rudder, after the rear bulkhead failed. It flew for 32 minutes before crashing.

    @viking68 - thanks for correction - yes, centripetal is the inward force, while centrifugal is the outward force, with respect to the centre of rotation.

    Reactor one currently is radiating 34 Sv/ Hr (34,000 mSv) in the dry well (DW), spiked at 300+ Sv/ hr on 27th September, and around 675 mSv/ Hr in the suppression chamber (SC), unlike reactors two and three, where the corresponding figures are 8.9 Sv/ hr (DW) and 6.9 Sv/ hr (SC), and reactor three 3.39 Sv/ hr (DW) and 0.3 Sv/ hr (SC). Source //atmc.jp.

    That would suggest that the situation in reactor one is quite different to the others, with a lot of the melted fuel rods outside of the reactor vessel. Radiation is too intense to allow inspection by both silicon-based robots or carbon-based workers. Whether it has leaked further outside of the dry well is not known, but it could account for the high levels of radiation in the cooling water. All 'educated guesswork' of course!

    Guess few people here have heard of centrifugal forces, which would keep people in their seats, and not notice the severity of the manoeuvre, especially in the dark. Planes at the old Hong Kong Kai Tak airport used to regularly tilt over on approach, but it never affected the passengers, except to give them a great view of Hong Kong people&s washing lines.

    However a close look at cockpit design and ergonomics is required, if one ANA pilot can make this mistake, so could others.

    It's not exactly a Captain Bligh-style lashing with a cat o'nine tails, it is more of a ritual humiliation; the whipper must keep a copy of the Koran wedged between his arm and his body, preventing large strokes.

    Still one step forward, two steps back for women in Saudi Arabia. Progress: Saudi -style...

    @farmboy - don't think bioremediation works at the atomic level, it has no effect on isotope degradation and subsequent release of radiation. In addition, heavy metals such as the isotopes involved are not readily absorbed or captured by organisms. Finally, how do you get rid of the organisms which have ingested any of the radioactive substances, when they are still radioactive?

    @crazy joe - I think you mean Fuji Heavy for the wings, parent company of Subaru, and longtime descendant of Nakajima Aircraft Co, who built some very reliable WW2 bombers.

    Some issues with steel/ fibre/ resin bonding and the glue/ process, leading to wings needing to be re-made, caused part of the delay.

    The Typhoon/ Eurofighter has been a disaster with the UK Royal Air Force, who now rue getting rid of the Tornados, Buccaneers and Harriers in order to be able to afford them. Good performance over a short distance, meaning that they can't fight effectively without a tankering capability; maintenance intensive, full of add-on packages to do the jobs that should have been built in from the start; and short of parts despite the fact that UK's own BAE is a primary manufacturer of it. The Brits were drooling over the war in LIbya to advertise what it could do, despite the fact that a Cruise Missile from one of their old Navy subs sitting in the Med could do the job at a fraction of the price, or even a scrapped Harrier off one of their now scrapped carriers. With the Typhoon you are not just paying for the plane, you are paying to keep 1,000s of BAE employees in jobs, and keep their skills and experience.

    It seems that most of the "growth" of the last 20~30 years has been based on dubious paper or electronic dealings such as derivatives and other esoteric financial instruments, leading to more and more of the world's wealth being concentrated in the hands of the financiers, who are the only ones who can understand them. They in turn leant this 'wealth' to governments and corporations, whose fate is now determined by shareholder value, and their ability to pay back their debts.

    It is now apparent that this is all valueless, the house built on and out of sand is due to collapse...

    Plenty of time to shred any remaining evidence, produce false documentation, prepare witnesses... He'll be found innocent of course.

    @sillygirl - there have been a number of whistleblowers at TEPCO and other utilities, from Itoh who exposed the incorrect manufacture and his own falsification of QC data of one of the reactor vessels resulting in a non-cylindrical shape, he was rewarded with a 3M Yen bonus at that time; to the WB who exposed the "editing" of the sodium fire at Monju. Kei Sugaoka, a Japanese-American, who worked for GE in Japan is probably the most famous, fired for reporting structural damage to reactors and then being told to cover up the damage.

    Are these checked and calibrated against a known radioactive source?

    Otherwise they are just useless.

    Chubu's problem is not the sea, it is the fault lines nearby. If a quake ruptures the pipes that carry cooling water, and the emergency scram cooling, to the actual reactor vessel, the unit is going to meltdown, as happened at the Fukushima NPP, despite all the attempts to blame everything on the tsunami.

    Some kindly utility-sponsored academic shortened the fault lines on the application, reducing the threat, but going against the advice of more experienced geologists, and of course when the residents took the case to court, the judge threw it out.

    Then there is the lesser issue of falsified inspection and QC data, and the proper repair of heat exchanger pipes, after a loose cover smashed a bunch of them when it came off, leading to inflow of radioactive material into the external cooling loop.

    And thus starts the end of the Noda government.... after 8 days! Wait for the LDP and others to start calling for Noda's resignation next, to take responsibility for appointing him.

    The pathetic circus that passes for Japanese politics plays on...
