Reactor3 seawater tunnel layout drawings differ from Tepco’s maps

High level of radioactive material is detected on the seaside of reactor3 as well.

(cf, 180,000 Bq/m3 of all β including Sr-90 detected at 4m from the sea without impervious wall [URL])

Tepco assumed it’s from the retained water in the tunnel called “seawater trench” underground. It’s also assumed that the retained contaminated water is being exchanged with seawater, so the distance from the sea is the important information.

On 8/2/2013, Tepco submitted the report about the groundwater contamination to Nuclear Regulation Authority.

However in the report, two maps show different locations of the issued seawater trench on the seaside of reactor3.

The map below shows the comparison of the two drawings.

The top one indicates the locations of the newly planned borings. The bottom one indicates the depth of the trench, which is frequently published.

The bottom one shows the seawater trench (Green line) is relatively far from the sea. On the other hand, the top one shows it’s quite close to the sea, and it’s under another trench for the power cable.

In order to indicate the boring locations, the top one seems more accurate about the layouts of plant structures.

Truth is not truth because everyone believes in it. It’s the truth because it’s consistent and can’t be rebutted.

Les positions des tunnels d’eau de mer du réacteur 3 diffèrent selon les plans de Tepco


On relève une radioactivité extrême aussi du côté mer du réacteur 3. (cf. 180 000 Bq/m³ de β-nucléides dont le strontium 90 relevés à 4 m de la mer sans mur souterrain étanche)

Tepco suppose qu’elle est dans l’eau retenue dans le tunnel nommé “tranchée d’eau de mer”. Ils supposent aussi que les eaux extrêmement radioactives qui y sont retenues se mélangent avec celles de la mer, donc la distance à la mer est une information importante.

Le 2 août 2013, Tepco a soumis à la Nuclear Regulation Authority un rapport sur la contamination souterraine.
Or, on trouve dans ce rapport deux plans donnant des positions différentes pour cette tranchée d’eau de mer à l’Est du réacteur 3.

Le plan ci-dessous fait la comparaison entre les deux : En haut, le plan des nouveaux forages prévus. En bas, celui souvent utilisé pour donner la profondeur de la tranchée.
Celui du bas présente la tranchée d’eau de mer (en vert) comme étant relativement loin de la mer.
Celui du haut l’en rapproche beaucoup et la positionne sous une autre tranchée, celle des câbles électriques.

Celui du haut semble plus juste sur l’agencement des structures de la centrale pour indiquer la position des forages.

Ce n’est pas la vérité parce que tout le monde y croit. C’est la vérité parce que c’est cohérent et irréfutable.

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.
