Tritium leakage from reactor 5 and 6

On 9/21/2012, Tepco released the nuclear analysis result of radioactive materials in the sea water.

The samples were taken on 4/16 and 5/14, so their release is 5 ~ 4 months behind.

The result shows 3.8 ~ 6.0 Bq/L of tritium leakage from around reactor 5 and 6 (North of Unit 5-6 Discharge Channel).

Tepco evaluates it is from the Fukushima accident.  From April to May, the tritium amount increased.

Fuite de tritium des réacteurs 5 et 6

Le 21 septembre 2012, Tepco publie l’analyse nucléaire des éléments radioactifs dans l’eau de mer.

Les échantillons ont été pris les 16 avril et 14 mai, donc leur publication a 5 à 4 mois de retard.

Les résultats montrent de 3,8 à 6,0 Bq/L de tritium en fuite autour des réacteurs 5 et 6 (au Nord du canal de sortie/décharge des unités 5-6).

Tepco estime que ça date de l’accident de Fukushima. D’avril à mai, la quantité de tritium a augmenté.

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.
