Tepco gave up pumping up contaminated water beside 4 crippled reactors to discharge to the sea

Tepco is going to give up discharging the contaminated water pumped up from “sub-drain”, they announced in the press conference of 10/29/2014.

They revised the retained water processing plan on the assumption that they cannot use “sub-drain”.

 

Tepco restricted the stakeholders to be only the local fishing industry excluding other normal citizens so that they can obtain the discharging approval easily.

They expected to discharge from this November.

However having high level of radioactive material continuously detected, local fishing industry did not give Tepco the approval to discharge.

 

It was stated that it would have reduced the daily contaminated water flowing to the plant buildings by 200 t discharging the contaminated water pumped from “sub-drain”. Without “sub-drain”, over 100,000 t of the contaminated water would remain to be partially purified in the tanks by the end of 2014.

Tepco abandonne le pompage à côté des 4 réacteurs dévastés de l’eau radioactive destinée à être déversée en mer

Lors de la conférence de presse du 29 octobre 2014, Tepco annonce qu’ils vont abandonner les déversements en mer des eaux radioactives pompées dans les “sous-drains”.
Ils ont revu leur plan de traitement des eaux retenues sur l’hypothèse qu’ils ne pourront pas utiliser les “sous-drains”.

Tepco avait limité les parties concernées aux seuls membres de l’industrie locale de la pêche à l’exclusion de tous les autres habitants en pensant ainsi obtenir un accord plus facile.
Ils prévoyaient de commencer les déversement en novembre.
Néanmoins, relevant l’augmentation continue d’une radioactivité énorme,  les pêcheries locales n’ont pas donné leur accord à Tepco pour ces déversements.

Ils avaient affirmé que ça aurait réduit le volume quotidien d’eau inondant les bâtiments de 200 tonnes en déversant les eaux pompées des “sous-drains”. Sans ces “sous-drains”, fin 2014 on aura plus de 100 000 tonnes d’eau radioactive partiellement filtrées dans les citernes.

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.
