All β density constantly increasing outside of the underground wall / Contamination rising from deep underground ?

Related to this article.. Underground wall on the seaside of reactor3 was possibly broken / Groundwater level in sync with ebb and flow [URL]


All β nuclide (including Strontium-90) density in groundwater has been increasing since this December on the seaside of reactor2 and 3.

It went up to over 10 times much within 3 months, according to Tepco. However the sampling location is outside of the underground wall, which Tepco completed the construction by December. The location therefore is separated from the reactor buildings, but facing the sea.


At another sampling location inside of the wall, All β nuclide density has not been increasing from Tepco’s data. There is no explainable path of contamination but it rose up from underground deeper than the underground wall.

Regarding this trend, Tepco hasn’t made any announcement.



Downplay it in the beginning, and quietly add more information so nobody notices it. All for not letting the cattle escape. This is their strategy.

Au delà du mur souterrain la radioactivité β augmente en permanence : Elle passe par dessous ?

Sur le côté mer des réacteurs 2 et 3, la radioactivité β (dont le strontium 90) des eaux souterraines augmente depuis décembre.

Selon Tepco, elle s’est multipliée par plus de 10 en 3 mois. Or, l’endroit échantillonné se trouve à l’extérieur du mur souterrain que Tepco a terminé en décembre. L’endroit est donc séparé des bâtiments et face à la mer.
Selon les données de Tepco, un autre échantillon pris à l’intérieur de l’enceinte du mur montre que la radioactivité β n’y a pas augmenté. Il n’y a pas d’autre explication au chemin suivi par cette radioactivité  que celui remontant après être passé par dessous ce mur souterrain.
Tepco n’a fait aucune déclaration concernant cette propension.

Le minimiser au début et ajouter tranquillement de nouvelles information pour que personne ne le remarque. Tout pour que le troupeau ne s’échappe pas. C’est leur stratégie.

  1. The geology reports show that there is no impermeable layer.

    The photos and slide shows appeared to show corium going down into the earth.

    Japan lost control of this disaster, long ago.

    1. Which photos and slide shows are you referring to, Bill? Can you supply a URL?

  2. Martin,

    TEPCO released these robot films quite some time ago. Regarding the links and elapsed time, I can probably, eventually, ‘cough them up’.

    Also the corium bright lights, clearly visible at night, on the distant, constant webcams.

    And the red, brightly glowing corium slugs, in the Fukushima Power Station yard, visible from the helicopter films.

    There was nothing secret about it, at the time.

    1. Some partial references to the corium location speculation and measurement methodologies.

      Asahi Shimbun, Jan. 24, 2014: [Tepco] has yet to learn where the nuclear fuel currently lies. The locations and amounts of the melted nuclear fuel should be identified by the time the government and TEPCO plan to start extracting it in the first half of fiscal 2020. Even if the melted fuel has escaped into the basement levels, it can still be located by installing [muon] sensors in underground holes, the scientists said.

      Kyodo News, Jan. 23, 2014: The condition of the melted nuclear fuel remains unknown […] “The (cosmic ray) measurement system can be installed easily,” said team member Hidekazu Kakuno, associate professor at Tokyo Metropolitan University. “We are ready to use it at the Fukushima Daiichi plant if TEPCO cooperates.”

      RT, Jan. 23, 2014: [Fumihiko Takasaki, a researcher at the High Energy Accelerator Research Organisation] claims that TEPCO has not yet officially confirmed that it will use the technology it is being offered.

      See also: AFP: Fears that molten fuel went into ground after melting through containment vessels at Fukushima — They still can’t find three reactor cores (AUDIO)

    2. Either the Muon results are pending or suppressed. In any event the continued Japanese cultural tendency toward mass suicide is accelerating in the 21st Century. Perhaps this is as a result, to some extent with never coming to terms with the past (dark-secrets).

      (2 YEARS ago, within weeks of meltdown, US experts urged Japanese Authorities to take immediate steps to prevent GROUNDWATER contamination, being ignored➨It was obvious to us there was great deal of groundwater intrusion http www theguardian com/ (world/2013/sep/19/future-japan-fukushima-leaks-pm )

      (Muon imaging may offer the best hope of assessing damage to the reactor cores (#Corium) and locating the melted fuel. http phys org/ (news/2013-08-core-fukushima) html )

  3. Similarly, the geology of Fukushima is a long-slog. TEPCO characteristically lied. TEPCO promoted a FICTION of an impermeable formation structure about 20 or 30 meters in depth, if memory serves.

    The geological reports CLEARLY showed that the purported ‘impermeable layer’ was highly fractured. I am not going to rewatch all those films and pore over the records, to relearn these basics. The matters are all in, or have been in, the public record. Right this instant, I am a bit more concerned with the WIPP nuclear incidents-accidents, near Carlsbad, New Mexico, than with continued documentation of Japanese Government mass suicide rituals.

    The Geology of Fukushima

      East-West cross-section (Thanks to Hiroko for her help in translation)

      This cross-section shows a ground discontinuity at a depth of around 200 m, corresponding to a change in the nature of the rock. Between ground level and -200 m, we find the geological layer of Tomioka, dating from the Neogene; the layer below it is older, it is labeled as belonging to the Paleogene – Neogene and corresponds to the Taga layer.

      The third paper presents a detailed analysis, also shown in two cross-sections, of the various geological strata inside this thick Cenozoic sedimentary coating. This is the list of the main strata, identified by letters, from the closest to the surface ground, down to the deepest. It is followed by maps, cross-sections and an analytical table:

    TOKYO | Tue Jun 4, 2013 9:44am BST

    (Reuters) – Tokyo Electric Power Co said on Tuesday it had detected radioactive caesium in groundwater flowing into its wrecked Fukushima Daiichi plant, reversing an earlier finding that any contamination was negligible. The announcement is yet another example of Tokyo Electric initially downplaying a problem, only to revise its findings because of faulty procedures. It casts further doubt over its control over the cleanup of the worst nuclear disaster since Chernobyl in 1986.

    “Once again, they’ve missed something they should be aware of,” said Atsushi Kasai, a former researcher of radiation protection at the Japan Atomic Energy Research Institute. “This shows again they lack the qualification to be managing the plant, which is the root cause of their failure to contain the March 11 disaster.”

    1. Mr. Duff writes here often, this is true.

      His comments are prolific, but in no way hijacking anything.

      His writing is rational, reasonable, sane, and literate.

      I do not agree with all he says, but I respect his thoughts and comments.

      I invite you to join in the conversation at a more dynamic level, without personal attacks.

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.
