To state the obvious , there has been considerable discussion and controversy concerning what actually happened during the frantic days after March 11th , what was the nature of the various explosions - were they merely hydrogen gas or something more menacing ? Here is a piece with a controversial point of view.
Monitoring data saturated after the nuclear explosion of reactor 3

Fukushima prefecture monitored radiation level around Fukushima plants.
On 2/7/2012, they released the monitoring data after 311. The data was taken in Ohno Ohkuma machi.
The facility is Nal scintillation spectrometer detector.
The graphs below are the spectral data.
Reactor 3 had nuclear explosion at 11:01 3/14/2011.
The bottom 2 graphs are the ones of 22:30 3/14/2011 and 10:30 3/15/2011.
The reactor 2 and 4 exploded at 6:00 3/15/2011.
Those 2 graphs are showing the saturation of low level of energy in the spectral data. It is impossible even to detect the nuclides.
and another Bank leaves Japan - are we onto a trend here....
HSBC is evacuating Japan

Following up this article..4 major Japanese corporations are evacuating to Osaka
The Hongkong and Shanghai Banking Corporation is going to withdraw from Japan.
On 2/22/2012, they announced they will close their retail banking service called HSBC premier, which they have been serving in Japan since 2008.
The customers were informed by email, sent at 20:30 2/2/2012 all of a sudden though HSBC has been denying the possibility of their withdrawal from the premier service for people who have the assets of more than 10 million yen.
They are going to close the Nagoya branch on 4/27.
Hiroo, Yokohama, Akasaka, Marunouchi, Oosaka branches will be closed on 7/31.
Marunouchi alpha, Akasaka alpha, ATMs of each branch, ATM at Narita airport, ATM at Nihonbashi HSBC building will be closed on 7/31 as well.
They already stopped opening new account on 2/23/2012.
HSBC has been involved in Japanese financial industry since over 140 years ago.
Japanese retail banking market is assumed to be 1471 trillion yen scale. HSBC has been competing with Citi group, Standard Chartered, Mizuho Bank or Mitsubishi UFJ financial group.

Cesium pollen full swing

Following up this article ..Cesium pollen started attacking Tokyo
A private weather forecasting company, weather news announced the amount of pollen in Tokyo, Kanagawa, Chiba, Saitama, Ibaraki, Tochigi and Shizuoka have gotten into the peak.
On 2/27/2012, Kanto area was sunny, dry and windy, which is the best condition for pollen to fly. More amount of pollen flew toward the evening. As it gets warmer in March, the pollen amount will increase more.

ウェザーニューズは2012年2月27日、関東で花粉飛散数が増加し、今日以降も飛散数が増える見通しであることから、本日東京都を含む1都6県が本格花粉シーズンに突入したと発表した。同社が本日花粉シーズンに突入したとしているのは東京都の他、神奈川県、千葉県、埼玉県、茨城県、栃木県、静岡県。これらの地域に在住の花粉症の方は、最新の花粉飛散情報を確認し、十分な対策を取る必要があるとしている。
ウェザーニューズは2012年2月27日、関東で花粉飛散数が増加し、今日以降も飛散数が増える見通しであることから、本日東京都を含む1都6県が本格花粉シーズンに突入したと発表した。同社が本日花粉シーズンに突入したとしているのは東京都の他、神奈川県、千葉県、埼玉県、茨城県、栃木県、静岡県。これらの地域に在住の花粉症の方は、最新の花粉飛散情報を確認し、十分な対策を取る必要があるとしている。
同社によれば、2月前半は強い寒気の影響を受けて寒い日が続き、花粉の飛散は抑えられていたという。ただ、先週からは日本海側でも雨が降るなど、寒気がいったん緩んだ状態となった。今日の関東地方は晴れて空気が乾燥し、さらに風が強く吹いているため花粉が飛散しやすい状態となり、本格花粉シーズンに突入したとのこと。関東地方は朝から花粉の飛散量が増加しており、夕方をピークにさらに飛散量は増えていく見通し。今後、3月に入る頃には一段と寒さが緩み、花粉の飛散量が増えていくと予想されている。
最新の花粉飛散情報は、同社の PC 向けサイト、携帯サイトおよびスマートフォンサイトの「花粉Ch.」で確認できる。
同社の今回の判断は、同社が全国各地1,000か所に設置している花粉観測機「ポールンロボ」の観測結果が根拠となったもの。同観測機で観測された花粉飛散数が1日あたり30個を超えると花粉症の症状が出始めるため、この数値を超えた地域を「本格花粉シーズン」に突入しているとしている。ポールンロボによって東京都、栃木県、静岡県で24日金曜日と27日午前中に観測された花粉の飛散数は次の通りだった。

A small leak was found in one of the two lines of Toshiba/IHI/Shaw's cesium absorption system "SARRY" on February 25, 2012. SARRY is housed inside the Miscellaneous Solid Waste Volume Reduction Treatment Building (so you don't need to scream "another frozen pipe!). TEPCO says the leak was about 10 liters.
TEPCO says the leak was at the welded part of the pipe, but looking at the second photograph it is from below the weld. The water is shooting out as if from a pinhole:

As TEPCO put it on their unofficial English handout for the press (2/25/2012):
[2nd Cesium adsorption apparatus (SARRY)]
・At 8:30 am Today (Feb. 25), TEPCO worker and partner companies’ worker found water leakage at welded part of piping at B line of 2nd Cesium adsorption apparatus (SARRY) placed on the 1st floor in Miscellaneous Solid Waste Volume Reduction Treatment Building (High Temperature Incinerator Building) of Fukushima Daiichi Nuclear Power Station. The leakage is just a drop per second and the amount of water leaked is approx. 10 litters [sic] (2m X 5m X 1mm). Those leaked water are stayed in barrier in the building and it did not leaked to out of the building. At 10:44 am, we stopped operation of SARRY and closed valve positioned in the upstream of leaked point to prevent further leakage of the water. We confirmed that the leakage was stopped at 11:10 am. Surface radiation is approx. 4-5mSv/h (2mSv/h in the back ground). We sampled the leaked water and analyzed the radioactivity concentration. The result is that I-131 was lower than the detectible limit, Ce-134 was 1.3×10^5 Bq/cm3 and Ce-137 was 1.8×10^5 Bq/cm310. The treatment of accumulated water is not affected by suspending the SARRY and there is no effect to the water injection to the reactor since there is a lot of purified water in the buffer tank.
("litters" is very cute.)
Luckily, since the once-highly contaminated water from the turbine buildings is not so highly contaminated like it used to, as it gets diluted by 500 tonnes/day groundwater that keeps coming every day into the basements of the reactor buildings and the turbine buildings. Still, the radioactivity of the leaked water was:
Luckily, since the once-highly contaminated water from the turbine buildings is not so highly contaminated like it used to, as it gets diluted by 500 tonnes/day groundwater that keeps coming every day into the basements of the reactor buildings and the turbine buildings. Still, the radioactivity of the leaked water was:
- I-131: ND
- Ce-134: 1.3 x 10^5 Bq/cubic centimeter
- Ce-137: 1.8 x 10^5 Bq/cubic centimeter
- Surface radiation: 4 to 5 millisieverts/hr in the 2 millisievert/hr background
When the water treatment started in June last year, the radioactivity was in the order of 10 to the power of 6 per cubic centimeter. The radioactivity is now low enough so that TEPCO doesn't need to use AREVA's co-precipitation and condensation system any more for daily operation.
TEPCO is doing what it is good at, which is small maintenance here and there for the smooth operation of a plant. The difference now is that the plant is totally broken as you see in the photos in my previous post. But tending to a bad weld that is leaking is totally within TEPCO's comfort zone, minus radiation. Strange, desolate calmness about the whole thing.
