Contaminated water crisis

Potential Strontium-90 density increased 22 times much in 3 days at 24m from the sea

According to Tepco, all β nuclides jumped up 22 times higher in 3 days. All β nuclides include Strontium-90.

The locations is Boring No.2, where is on the east side of reactor2. It’s 24m from the sea.

On 7/15/2013, all β nuclide reading was 49,000 Bq/m3. It became 1,100,000 Bq/m3 on 7/18/2013.

The reason is not announced.

Le strontium 90 a sans doute été multiplié par 22 à 24 m de la mer en 3 jours

 

Selon Tepco, les β nucléides se sont multipliés par 22 en 3 jours. Les β nucléides incluent le strontium 90.

C’est au forage n°2 qui est à l’est du réacteur 2 et à 24 m de la mer.
Le 15 juillet 2013, les relevés en β nucléides étaient à 49 000 Bq/m³. C’est passé à 1 100 000 Bq/m³ le 18 juillet 2013.
La raison  n’en est pas donnée.

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.
