[New leakage] 200,000,000 Bq/m3 was leaking for 12 hours max / Patrol didn’t notice “because it was raining”

Following up this article.. [New leakage] Contaminated water flowed to the Pacific outside of the port / Radiation level still under analysis [URL]

 

Because the leakage started when they transferred the rainwater to the tank, the leakage may have been continuing for 12 hours at the maximum according to Tepco.

They don’t know when it started nor when it ended.

They patrol the tank areas 4 times a day. The workers checked the tank in the afternoon of 10/3/2013, but they couldn’t distinguish the leakage and the rain. After all, they didn’t the leakage until 20:00 of the day.

American economic crisis is severely damaging Fukushima Diary. I’d be extremely happy if you consider donation.

Thank you very much.

[Nouvelle fuite] 200 millions de Bq/m³ ont fuit pendant au plus 12 heures : Les patrouilles n’ont rien vu “parce qu’il pleuvait”

Selon Tepco, la fuite a du se prolonger tout au plus pendant 12 heures parce que la fuite a commencé quand ils ont commencé à transvaser les eaux de pluies dans la citerne.
Ils ne savent ni quand ça a commencé, ni quand ça s’est arrêté.
Ils patrouillent 4 fois par jour dans les zones des citernes. Des employés ont contrôlé les citernes dans l’après-midi du 3 octobre 2013 mais ils ne pouvaient pas distinguer la fuite de la pluie. Ils n’ont finalement pas vu la fuite avant 20:00 ce jour-là.

La crise économique américaine nuit gravement au Fukushima Diary. Je serai extrêmement heureux si vous pouviez faire un don.

Merci beaucoup.

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.
