[Leakage] Radiation level jumped up over 10 times much as 2 days before OUTSIDE of reservoir No.1

According to Tepco, total β nuclides level spiked up outside of reservoir No.1. Reservoir No.1 is one of the leaking reservoirs of highly contaminated water.

It’s on the South West side of the reservoir. The sample is drain hole water.

At 12:05 of 4/26/2013 (JST), they measured 41,000 Bq/Kg of the total β nuclide.

At 12:05 of 4/28/2013, it jumped up to be 1,100,000 Bq/Kg, which is over 10 times much as the previous reading.

Tepco hasn’t verified the reason yet.

[Fuites] Le niveau de radioactivité s’est multiplié par 10 en 2 jours A L’EXTÉRIEUR du réservoir N°1

 

Selon Tepco, le total de β nucléides monte en flèche à l’extérieur du réservoir N°1.
Le réservoir N°1 est l’un de ceux qui fuient une eau extrêmement radioactive.

C’est au Sud-Ouest du réservoir. L’échantillon provient du trou de vidange.
Le 26 avril 2013 à 12:05 (JST), ils relevaient 41 000 Bq/kg en total des β nucléides.
Le 28 avril 2013 à 12:05, c’est passé à 1 100 000 Bq/kg, c’est plus de 10 fois le relevé précédent.
Tepco n’en a pas encore vérifié la cause.

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.
