Tepco to discharge 2,000 ~ 3,000 Bq/ml of tritium to the sea, “50 times much as legal limit”
Tepco is going to discharge contaminated water to the sea. (cf, Tepco officially announced to discharge contaminated water into Pacific ocean [URL])
Tepco states the discharged water will be purified by the purifying facility “Alps”, but it can’t filter out the nuclide called “tritium”. Tritium is radioactive water.
It is estimated that the water contains 2,000 ~ 3,000 Bq/ml of tritium even after purification, which is 33 ~ 50 times much as the legal limit to discharge.
Tepco comments they will dilute it before discharging but the total amount of tritium would be the same.
Tepco va décharger en mer les eaux contaminées. (cf. Tepco annonce officiellement qu’ils vont décharger les eaux contaminées dans l’océan Pacifique [Lien])
Tepco affirme que les eaux larguées seront d’abord purifiées par le système de purification “Alps” mais il ne filtre pas le nucléide nommé “tritium”. Le tritium est de l’eau radioactive.
On estime que l’eau contient de 2 000 à 3 000 Bq/ml de tritium même après purification, soit entre 33 et 50 fois la limite légale pour les rejets.
Tepco dit qu’ils la dilueront avant le largage mais le total en tritium restera le même.
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.
