Tepco finally admitted the “possibility” that contaminated water penetrated to the deep layer of the ground
Tepco finally admitted the possibility that contaminated water penetrated to the deep layer of the ground. Tepco announced in the extraordinary press conference of 6/24/2014.
Fukushima Diary has been pointing out the possibility for months.
(cf, Tritium density in deep underground broke the highest record ever, 4,700,000 Bq/m3 [URL])
Tepco was stating that the contaminated water reached 15m underground, but it’s stopped by impermeable layer right underneath.
However 120,000 ~ 140,000 Bq/m3 of Tritium was measured 25m underground from the sample of 6/10/2014 as well.
Tepco is still “under investigation” for the cause, but they are stating the construction of frozen water wall might have spread the contaminated water accidentally.
If the contaminated water is penetrating to deep layer of the ground, there are few measures to stop it spreading. It can also travel underground of the ocean bed to come up to the sea offshore of Fukushima plant.
Tepco affirmait que les eaux extrêmement radioactives étaient descendues jusqu’à 15 m en sous-sol mais qu’elles avaient été arrêtées par la couche imperméable juste en dessous.
Or, dans un échantillon du 10 juin 2014, on relevait à nouveau entre 120 et 140 000 Bq/m³ de tritium à 25 m de profondeur en sous-sol.
Tepco est toujours “en investigation” pour en trouver la cause et ils affirment que la construction du mur congelé a pu accidentellement répandre la radioactivité.
Il y a peu de solutions pour empêcher la diffusion des eaux extrêmement radioactives si elles pénètrent dans les couches profondes. Elles peuvent alors voyager en sous-sol sous l’océan et ressurgir en mer bien au large de la centrale de Fukushima.

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.
