NRA “Groundwater contamination is possibly spreading. It can be directly leaking from reactor1 turbine building”

In the working group of 1/24/2014, NRA (Nuclear Regulation Authority) pointed out the possibility that Tritium is spreading underground of seaside of reactor1.


In two boring holes beside reactor1 turbine building, Tritium density has been increasing since last November. Tepco has no clear answer about this.

Last November, Tepco admitted the coolant water is leaking out from reactor1 vessel. (cf, [Video] Reactor1 confirmed leaking out the coolant water / 2.0 Sv/h [URL])

NRA suggested the possibility that highly contaminated water is leaking from reactor1 turbine building to underground too. This suggests the vessel coolant water is possibly leaking to the sea directly, however it hasn’t been verified since last summer.

La NRA : “La contamination souterraine s’étend. Ça peut fuir directement de la turbine du réacteur 1”

Au cours de la réunion du groupe de travail du 24 janvier 2014, la NRA (Nuclear Regulation Authority) a mis en avant que du tritium se répand probablement dans le sous-sol du côté mer du réacteur 1.

Dans deux trous de forage à côté du bâtiment de la turbine du réacteur 1, la radioactivité en tritium augmente depuis novembre dernier. Tepco n’a pas apporté réponse claire à ce sujet.
En novembre dernier, Tepco a reconnu que le liquide de refroidissement s’échappe de l’enceinte du réacteur 1. (cf.[Vidéo] Fuite confirmée au réacteur 1 pour le liquide de refroidissement : 2 Sv/h)
La NRA fait aussi une hypothèse de fuite d’eaux extrêmement radioactives en sous-sol du bâtiment de la turbine du réacteur 1. Ceci suggère que le liquide de refroidissement s’écoule directement en mer bien que ce n’ait pas été vérifié depuis l’été dernier.

Merci de lire le Fukushima Diary. Votre soutien est l’énergie de mon travail opiniâtre.

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.
