Tepco “30,000,000,000,000 Bq of Cs-137 and Sr-90 leaked to the Pacific” / 30,000,000,000 Bq still leaking per day

On 8/21/2013, Tepco announced 30,000,000,000,000 Bq of Cesium-137 and Strontium-90 have leaked to the sea since May of 2011. This is over 100 times much as their management standard volume of leaking radioactive material.

Still 30,000,000,000 Bq of Cs-137 and Sr-90 are leaking to the Pacific everyday.

This estimate is based on the same assumption as when they announced 40,000,000,000,000 Bq of Tritium has leaked to the Pacific.

(cf, Tepco “40,000,000,000,000 Bq of Tritium leaked to the Pacific” / still 100,000,000,000 Bq leaking to the sea per day [URL])

Tepco assumes the largest contamination source is the trench and shaft.

Specifically, 10,000,000,000,000 Bq of Sr-90 and 20,000,000,000,000 Bq of Cs-137 are supposed to have leaked to the Pacific from 5.2011 to 8.2013.

10,000,000,000 Bq of Sr-90 and 20,000,000,000 Bq of Cs-137 are supposed to leak to the Pacific every single day.

However, this is on the assumption that Cs-137 and Sr-90 are floating in seawater instead of accumulated in the marine sediment.

The basis of this assumption is not announced.

Tepco : “30 Tera Bq de Cs 137 et Sr 90 ont fuit dans le Pacifique” / on en a toujours 30 milliards Bq/jour

 

Le 21 août 2013, Tepco annonce que 30 000 000 000 000 Bq de césium 137 et de strontium 90 ont fuit dans la mer tous les jours depuis le mois de mai 2011. C’est plus de 100 fois leur volume de fuites radioactives géré en standard.

On a toujours 30 000 000 000 (30 milliards) Bq de Cs 137 et Sr 90 qui fuient chaque jour dans le Pacifique.

Cette estimation est basée sur la même hypothèse que celle leur ayant fait annoncer que 40 000 milliards de tritium avaient fuit dans le Pacifique. (cf. Tepco : “40 Téra-Bq de Tritium ont fuit dans le Pacifique” / on en a toujours 100 milliards de Bq tous les jours qui partent en mer )

Tepco suppose que la plus grande source de contamination sont les tranchées et leurs hampes.
Spécifiquement, entre mai 2011 et et août 2013, 10 000 000 000 000 Bq de Sr 90 and 20 000 000 000 000 Bq de Cs 137 sont supposés avoir fuit dans le Pacifique.
10 000 000 000 Bq de Sr-90 et 20 000 000 000 Bq de Cs 137 sont supposés fuir chaque jour dans le Pacifique.
Cependant, c’est sur l’hypothèse que le Cs 137 et le Sr 90 flottent dans l’eau de mer au lieu de s’accumuler dans les sédiments marins.
La base de support de cette hypothèse n’est pas communiquée.

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.
