[Out of control] Tritium measured outside of 4 from 5 reservoirs, max reading 1.9 times much as 1 week ago

According to Tepco, radioactive water Tritium was measured outside of most of the reservoirs.

Among 7 reservoirs, highly contaminated water is stocked in 5 reservoirs. Tritium was detected from 4 of those 5 reservoirs.

The sample is drain hole water. Detecting Tritium from drain hole water means it’s already leaked to outside of the reservoirs.

Sampling date was 4/24/2013. Tepco didn’t take longer than 8 days to release the data though it’s in a holiday season in Japan.

On 4/25/2013, Fukushima Diary reported the first Tritium detection from the reservoirs.

(cf, [Out of control] Tritium leaked from 4 of 7 reservoirs, “1,100,000,000Bq/m3 from reservoir No.1″ [URL])

Last time, the highest reading of Tritium leaking outside of the reservoirs was 2,100,000 Bq/m3. (Drain hole water, Northeast side of reservoir No.1) This time, the highest reading was 3,900,000 Bq/m3 from the same location. It’s 1.9 times much as last time.

[Hors contrôle] Du tritium relevé en-dehors de 4 des 5 réservoirs, record de radioactivité doublé en une semaine

 

Selon Tepco, ils ont relevé du tritium dans l’eau radioactive prise à l’extérieur des réservoirs .

De l’eau extrêmement radioactive est stockée dans 5 des 7 réservoirs. Du tritium a été détecté sur 4 de ces 5 réservoirs.
L’échantillon est pris au trou de vidange de l’eau. Détecter du tritium dans le trou de vidange signifie qu’elle a déjà fuit en dehors du réservoir.
L’échantillonnage est du 24 avril 2013. Tepco n’a pas mis plus de 8 jours pour publier ces résultats bien qu’on soit en période de vacances au Japon.
Le 25 avril 2013, le Fukushima Diary rapportait la première détection de tritium hors des réservoirs. (cf. [Perte de contrôle] Le tritium fuit de 4 des 7 réservoirs : 1 100 000 000 Bq/m³ au réservoir N°1)
La dernière fois, le relevé en tritium maximum hors des réservoirs était de 2 100 000 Bq/m³. (trou de vidange, nord-est du réservoir  N°1) Cette fois-ci, il est à 3 900 000 Bq/m³ au même endroit. C’est 1,9 fois plus.

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.
