Violent fluctuations of hydrogen concentration in reactor1

Hydrogen concentration of reactor 1 has been fluctuating violently since 6/3/2012.

On the daily press conference of 6/4/2012, Tepco explained hydrogen gas is heterogeneous inside of PCV, the indicator captured the mass of high concentration by chance.

However, it dropped once on 6/9 and it picked up on 6/10 again.

There are 2 indicators for hydrogen concentration, system A and B. Both are in the same trend.

If hydrogen concentration goes over 4% (Oxygen 5%), there is the possibility of hydrogen explosion. Tepco is injecting nitrogen to control the hydrogen concentration.

  1. Correct me if I am wrong, but that chart is showing concentrations of .1 %, but you say explosions can happen at 4%. Got a ways to go before it gets even close to that bad..

    Also, doesn’t the presence hydrogen mean criticality is still occurring?

  2. how does a reactor that has melted out of it’s Containment vessel trap hydrogen?

    1. @pat b, the building has been entombed (the new structure) is my ‘uneducated’ guess, it has been covered, perhaps if it is a contained atmosphere it might become pressurized? maybe…

  3. I am very impressed with the work of Iori Mochizuki. In fact, as a nonprofit public service, I have created a week-by-week chart series titled “`Aerial Dance of Mass Death and Genetic Destruction’ Week-by-week Fukushima radiation and fallout projections and companion articles” whose table of contents is at http://tinyurl.com/3wm3rkw. One can also link to this series from my home pages at http://www.americafirstbooks.com and http://www.americafirstinstitute.com.

    I am trying to help the public make chronological connections between plume forecasts and news coming out of Japan and spikes in radiation readings in North America and Europe. Perhaps this approach will help many people overcome their state of denial who have resisted waking up by other means.

    I like the way Mr. Mochizuki not only reports on important technical details about status of Fukushima reactors and radiation readings throughout Japan, but also provides invaluable insights regarding the human dimensions within Japanese society. I would like to link to his articles and reference them as much as possible in the articles section for Japan for each week of the chart series, subject to any comments that Mr. Mochizuki may wish to make to me by personal email.

    I have created an author archive web page for Leuren Moret at http://tinyurl.com/64m37tq. She spent quite a lot of time in Japan prior to the Fukushima catastrophe trying to warn people about the dangers of nuclear power. Please see her 23 May 2004 article “Japan’s Deadly Game of Nuclear Roulette” published at japantimes.co.jp at http://www.japantimes.co.jp/text/fl20040523x2.html.

    I agree with Ms. Moret that the Japanese people have been victimized by external influences, to include strong evidence for HAARP and Stuxnet virus attacks and the likelihood of misdirection by the U.S. Department of Energy.

    I have helped transcribe Ms. Moret’s interviews with Dr. James Fetzer on his Real Deal Talk Show that provide important background on these issues. For example, please see the 18 July 2011 interview titled “Fukushima and the Global Danger” at http://tinyurl.com/3tqv6pl.

    I have also transcribed more recent interviews Ms. Moret has conducted with Dr. Fetzer and other experts, for example, “Fukushima Radiation Horrors,” 19 Aug 2011, at http://tinyurl.com/6z9f5ca; “Fukushima Radiation and Uranium Weapon Update” 28 Oct 2011 with Dr. Chris Busby at http://tinyurl.com/3ukrghe ; and “Fallujah, Fukushima, and the Global Radiation Catastrophe,” 3 Feb 2012, with Dr. Busby at http://tinyurl.com/7comd8m.

    There is also another interview I helped organize which covers Fukushima-related major media suppression and cover-ups. It is currently available only in MP3 and features a round table discussion by Dr. Fetzer, Leuren Moret, and Dr. Majia Nadesan on 30 March 2012. The MP3 file can be downloaded at this web page: http://radiofetzer.blogspot.com/2012/03/leuren-moret-maia-madison.html.

    Last, but not least, I have created other web pages that deal with the radiation threat from other perspectives, such as an individual and group protection web page at: http://tinyurl.com/7uwf4l5, a Chernobyl web page which serves as an important “case study” at: http://tinyurl.com/6qebag3, my Fukushima summary page at: http://tinyurl.com/4924xzn; an author archive web page for Dr. Chris Busby at: http://tinyurl.com/3k4zsty, and a web page that deals with the very real possibility that we could experience our own “Fukushima” here in the United States at: http://tinyurl.com/3tb6t9u.

    Leuren Moret and Dr. Chris Busby have estimated that Fukushima could be on an order of magnitude 300 times worse than Chernobyl. Please consider that in the 25 years following the 1986 Chernobyl meltdown an estimated one million people died early deaths, and another eight million have been incapacitated. Now multiply these numbers by 300 and we get 300 million early deaths and 2.4 billion incapacitated people over the next 25 years around the Northern Hemisphere from Fukushima radiation.

    We are facing the greatest man-made disaster in history. This could plunge mankind into another Dark Age. This is a total RED ALERT situation in which the survival of the Japanese and many other peoples around the Northern Hemisphere is at stake.

    We need many different approaches to help wake up the public to the enormity of the Fukushima radiation threat and terrible suffering that has already been inflicted on the people of Japan. Everything is likely to get much worse. However, there are still actions we can take now to greatly reduce or contain the horrific damage that we face over the next few decades.

    I invite comments from Mr. Mochizuki regarding the approach that I am taking, as well as from readers of his web site. My email address is americafirstinstitute@yahoo.com. Other contact information can be found on my contact web page at: http://tinyurl.com/b4jz79. One can also find background on myself at my author archive at: http://tinyurl.com/5r3xqh.

  4. In order to accumulate hydrogen there is a hydrolysis reaction going on. That strongly suggests that the corium is a molten blob – at least white hot. If so recriticality is possible and the chance of it is probably unknown. I don’t know if high radiation also causes hydrolysis. Anybody out there help with this concept?

  5. no report that reactor has melted, nor

    the reactor broken thru containment structure,

    which is designed to contain molten reactor vessel as well

    as full inventory molten fuel

    Japan unfortunately has skimped everywhere into the ramp up of its nuke

    industry, there open air burning of contaminated debree, to wit

    world war 3 should have been started the minute earthquake hit,

    to prevent Japan from poisening the rest of the world

    Japan up to today has done nothing meaningful, just head in the sand

  6. I agree that this is a very important source of information but once some people see conspiracy theorists involved who are apparently jumping on the bandwagon in order to further their cause of proving themselves right about things like HAARP – then this source will very likely lose it’s credibility, lose readers and gain more conspiracy theorists who have a tendency to cloud everything with abuse of words like “truth” and “proof”.

    If anything the conspiracy theorists are doing the job of the very people some of them claim are conspiring against us all. There’s possibly no better weapon than allowing and cultivating nutjobs within the movement of your enemies.

  7. Maybe a language issue but I do wonder if some people get “reactor” mixed up with “fuel”. Which to me is very interesting because I’ve often noticed that the media and official messages concentrate a great deal on “reactor” rather than “fuel” yet as far as I’m aware the real problem here is the fuel. When people in the nuclear industry or those who are pro nuclear, talk about how nuclear power from fission is so much cleaner – they tend to concentrate on the technology of generation of energy and neglect to mention the massive elephant in the room which is the highly toxic fuel used. It’s almost as if nuclear fission is some kind of magic wand or a renewable energy source. “It’s clean! see” as they sit atop a growing pile of radioactive and toxic material. Very odd.

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.
