Silt fence within Fukushima nuclear plant port disconnected, highly contaminated fish discharged

From 4/6 to 4/7/2013, a strong storm hit eastern Japan.

(cf, Storm coming to JP for this weekend, the maximum instantaneous wind speed is 30m/s [URL])

On 4/8/2013, Tepco announced the silt fence was damaged. They reported this,

At around 10:10 today, April 8, a corporate company worker found disconnection of the silt fence at the Unit 5/6 intake canal, and the silt fence at the shallow draft quay which was tied up to prevent fish from moving out.

Since the wave height is currently too high for strong wind to work around the area, we will repair the silt fence after the weather has quiet down.

We will conduct additional sampling in front of the Unit 6 intake canal today.

There are no significant changes with the monitoring post data.

La barrière de vase du port de la centrale nucléaire de Fukushima est rompue, des poissons hautement radioactifs sont sortis


Entre le 6 et le 7 avril 2013, une forte tempête a frappé l’Est du Japon. (cf. Une tempête sur le Japon ce week-end, vitesse maximale instantanée des vents à 30 m/s (= 108 km/h))

Le 8 avril 2013, Tepco annonce que la barrière de vase est endommagée. Ils le rapportent ainsi :

Aujourd’hui, 8 avril vers 10:10, un travailleur d’une entreprise a découvert une brèche dans la barrière de vase du canal d’entrée vers les unités5 et 6 et sur l’ébauche de quai de faible hauteur qui était arrimé pour em^$echer les poissons de sortir.
Comme la hauteur des vagues est actuellement trop grande et les vents trop forts pour travailler autour de la zone, nous réparerons la barrière de vase après que le temps se soit calmé.
Nous ferons des échantillonnages additionnels devant le canal entrant de l’unité 6 aujourd’hui.
Il n’y a aucun changement significatif dans les données des bornes de surveillance.

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.
