Fukushima plant radiation increasing due to the rising contaminated groundwater / “Covering with lead plate”

Related to this article.. Tepco gave up pumping up the rising contaminated groundwater on the seaside of reactor3 / “No tank capacity” [URL]


The atmospheric dose of the seaside of Fukushima plant is increasing due to the rising contaminated groundwater, according to Tepco.

Tepco is building the underground wall on the coastal line, but the exposure dose of the workers is going up.

Tepco states as they build the underground wall, highly contaminated groundwater is coming up to the surface of the ground.

In order to keep building walls, the workers are operating on the “stand” to be as far from the ground as possible and also use the lead plate.





I reject the international mass media to read this site without taking a contact with me.I know some of the mass media corporations read Fukushima Diary to understand the trend so they know when to report about Fukushima as if they were independently following it for a long time.
In short, they make you individual readers pay for this site while they pay nothing, and when they publish the “authorized news”, you pay for the “secondhand news”, which is nothing new for us.
This site is free for the individual readers, but not for corporations.In the world, this site is nearly the only source about Fukushima. I came here alone without any supporting organizations, background or anything. I’m not pleased to be exploited by the corporations that didn’t even properly report about Fukushima when 311 took place.

I demand them to take a contact with me BEFORE reading this site whatever the purpose is.

La radioactivité augmente dans la centrale de Fukushima à cause de la montée des eaux souterraines : “Couvrir avec une plaque de plomb”

Selon Tepco, sur le côté mer de la centrale de Fukushima la dose augmente à cause de la montée des eaux souterraines.
Tepco construit un mur souterrain le long du rivage mais la dose d’exposition des travailleurs augmente.
Tepco affirme que les eaux souterraines remontent vers la surface pendant qu’ils réalisent ce mur souterrain.
Les ouvriers sur le “stand” doivent travailler en étant aussi loin du sol que possible et en utilisant des plaques de plomb pour pouvoir continuer la construction.


J’interdis à la grande presse internationale de lire et d’utiliser ce site sans préalablement prendre contact avec moi. Je sais que certaines grandes sociétés de presse lisent le Fukushima Diary pour comprendre la tendance et trouver quand rendre compte de la situation de Fukushima comme s’ils la suivaient indépendamment depuis longtemps.
En résumé, ils vous font payer à vous, simples lecteurs, ce qu’ils prennent gratuitement dans ce site et lorsqu’ils publient des “nouvelles de première main” vous payez pour des “nouvelles resucées”, qui n’ont rien de nouveau pour nous.
Ce site est gratuit pour les lecteurs individuels, pas pour les sociétés. Ce site est pratiquement la seule source au monde sur Fukushima. Je viens ici seul sans aucun soutien d’organisation quelconque, ni références, ni rien. Je n’apprécie pas de me faire exploiter par ces sociétés qui n’ont même pas été foutues de relater correctement ce qui se passait à Fukushima quand a eu lieu le mois de mars 2011.

Je leur demande de prendre contact avec moi AVANT de lire ce site dans quelque but que ce soit.

  1. I do not know, if decision makers are reading the commentaries here at Fukushima Diary. Just in case they do, I would like them to proof, what I have written under

    “Tepco started pumping up the groundwater around the leaked tank
    Posted by Mochizuki on November 26th, 2013” (commentary number 9)

    If TEPCO pumps the radioactive (ground)water into oil tankers the tanks on the soil are not needed any more. The big oil tankers have a capacity up to 4 million barrels, that is approximately 476 thousand cubic meters.

    One of the big tankers alone can take up all the radioactive water, that is stored at the tanks on the soil.


    Furthermore, if TEPCO does not pump up the ground water, the area around and under Fukushima Daiichi Nuclear Power Plant becomes more and more muddy and more and more radioactive. At one point in time nobody can work any more at the facility (not on the ground) and the stability of the ground becomes so weak that the reactor buildings could collapse.



    Btw.: I appreciate your work Iori 😉

  2. As the ground around the plant becomes increasingly saturated and as radiation levels continue to rise, is there not a risk that ever-expanding areas of the plant will become no-go zones? And that the plant will eventually have to be abandoned, with all that implies?

  3. Uh oh..

    And they can’t pump up the contaminated groundwater because they’ve run out of tank capacity?

    Is there no more space for additional tanks?

    And didn’t Tepco just say that the radiation level of the groundwater is “low enough”?
    But I guess that’s not the case, huh.

    International Radiation Protection Association: “After a core meltdown accident it cannot be completely ruled out that the melt will reach, and partly penetrate, the concrete foundation. The amounts of some radionuclides leached out by the passing groundwater are estimated. The transport of dissolved radionuclides in groundwater is simulated by an analytical dispersion model […] a core meltdown accident could well cause the melt to penetrate into the reactor foundation and pass through it down to the bottom side of the foundation within five days. Even if the passing groundwater were to prevent complete melt-through, there would still be a direct contact of the groundwater with the re-solidified melt surface through fissures, cracks, etc., which could cause the fission products to be leached. […] Figure 1a shows the concentration in the groundwater and in the river water 500 m away from the reactor between 100 days and 100,000 days. The groundwater was assumed to be discharged into the river water 500 m from the reactor […] The highest radionuclide concentration of approx. 10^10 Bq/m3 [10 billion Bq/m3] is reached by Sr-90 after some 5,000 days.”

    Study identified by ENENews

    1. The radioactive Strontium 90 (SR-90) entering the Pacific should reach a PEAK Concentration level in about 11 more years.

      Using the study as a guidepost.

      That kinda sucks

  5. The SR-90 contamination of the Pacific will decline to insignificance in only about 270 more years. Again, according to the graph.

    For context and reference purposes, 1743 A.D. was two hundred and seventy years ago, James Watt invented the first reliable steam engine in 1775. Thomas Savery and Thomas Newcomen constructed some functional steam pumps prior to that. The Boulton and Watt steam engine powered the Industrial Revolution.

    George III (George William Frederick; 4 June 1738 – 29 January 1820) was crowned King of Great Britain and King of Ireland on 25 October 1760. He and Parliament had not yet angered the 13 American Colonies.

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.
