Contaminated water crisis

Contaminated water was found leaking into two more tunnels

Contaminated water was found leaking into two more tunnels

Following up this article .. Tepco found 140 tones of contaminated water leaking in a tunnel under the reactor

Tepco found out contaminated water has leaked into two more tunnels on 1/12/2012.
One of the two tunnels is connected to the turbine building of reactor3, which is about 300 tones.
They measured 1.6 microSv/h from the surface, but it’s not announced how much Bq/Kg of radionuclide it contains.
About the other leakage, nothing is announced about the location, amount, or the contamination level.

Tepco asserts those tunnels are not connected to the sea, but they still haven’t investigated where the water leaked from.

福島第一原発の地下トンネルから去年１２月、大量の汚染水が見つかったことから、東京電力は全ての地下トンネルについて汚染水がないか調査を進めていますが、１２日、新たに２か所の地下トンネルに水が溜まっているのが見つかったと発表しました。

今回発見された２か所のうち、３号機のタービン建屋につながる地下トンネルの汚染水はおよそ３００トンで、表面から１時間あたり１．６マイクロシーベルトの放射線量が測定されました。

東京電力ではトンネルが海につながっていないことから、汚染水が海に流れ出る恐れはないとしていますが、引き続き、他のトンネルの調査を続けるとともに、汚染水の流入経路などについて調べることにしています。（12日20:57）

  1. Great Post!
    Every drop of radioactive polluted water that escapes into the ground and or the Pacific ocean saves TEPCO huge amounts of money! We all know this and it is a “Planetary Crime” that is now ongoing because the Japanese Gov’t. is allowing it to happen!

  2. BTW: I just finished reading “Japan’s Tipping Point” by Mark Pendergras­t which is now available as either a paperback or as an ebook! He won an Abe Fellowship for Journalist­s, (an annual grant given to selected writers who then spend six weeks in Japan); he arrived two months after 3/11 visiting their Eco-Model Cities and interviewe­d many of Japan’s Eco “Leaders” both in Government and in the private sector.

    ===>One thing I learned is that Japan’s utilities own their electrical GRID and therefore are the only ones that can “approve” of any forms of energy accessing it! If Japan is to “kick” their Nuclear reactor habit, the Utilities will have to OK that decision, which means a reduction in both Control and Market share for them!
    snip
    “I discovered­, however, that the real power in Japan lies with bureaucrat­s who have strong ties to big business. They outlast the politician­s. The Ministry of Economy, Trade, and Industry (METI) is the most powerful bureaucrac­y, with a large budget at its disposal.”

    ==> Another thing I learned is that Northern Japan has a different form of alternatin­g current than Southern Japan so that Energy cannot be easily shared Nationwide­! This is yet another roadblock to low cost energy that the Utilities promote to protect their market share in Japan!
    snip
    “Each of the regional utilities jealously guards its borders, so that there is limited cooperatio­n between them. Transmissi­on lines are not large enough to allow power to flow easily between regions. Worse still, the northeaste­rn half of Japan uses a 50 hertz frequency, while the southwest operates at 60 hertz, making it impossible to share power between them without huge transforme­rs.”

    This to me, is the real “Tipping Point”, since without a “up to date” modern (Think SMART) grid energy cannot flow to where it is needed, when it is needed, at a fair price from where it is generated! Imagine installing new solar panels and the Energy produced is not allowed to be added to the grid because the Utility wants to only sell it’s own energy!

  3. I wish you would consider adding a “TIP” or “new news” Button:

    Seen This:
    Fukushima nuclear cleanup could create its own environmental disaster
    Decontaminating the Fukushima region to remove radioactive particles will not be possible without removing large amounts of soil, leaves and plants
    http://gu.com/p/34hdn
    snip
    “Decontamination can be really effective, [but] what you have is a tradeoff between dose reduction and environmental impact,” says Kathryn Higley, a radioecologist at Oregon State University who has studied several decontamination sites in the United States. That’s because the radioactive particles the Japanese are trying to get rid of can be quite “sticky”. Removing them without removing large amounts of soil, leaves, and living plants is nearly impossible. The Ministry of Environment estimates that Fukushima will have to dispose of 15 to 31m cubic metres of contaminated soil and debris by the time the decontamination projects end. Costs are predicted to exceed a trillion yuan.

    Given these drawbacks, an International Atomic Energy Agency fact-finding mission advised the Japanese authorities to “avoid over-conservatism” in their decontamination plans — in other words, not to clean up more than necessary to protect human health. Yet the health impacts of long-term exposure to low levels of radiation are not entirely clear. Many scientists believe exposure to even very low levels can slightly increase cancer risk, and many Fukushima residents feel they should not be forced to live with that risk — or the undercurrent of fear it brings.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
