12 tones of water leaked to the sea containing beta nuclides

12 tones of highly radioactive water leaked to the sea again. It leaked from the part after desalination unit, but because it can’t filter beta nuclides, Sr-90 and other nuclides have already leaked to the sea.
However, the leaked water contained 16.7E+6Bq/m3 of cesium too.

The flow from desalination unit to the tank increased by 140% at 0:06~0:13 4/5/2012, it automatically stopped.
At 0:50~1:10 4/5/2012, because a nuclear worker tried to restart the facility for 3 times, 3~4 tones of additional water leaked. Around at 2:20 4/5/2012, water leakage was stopped, Tepco reports.

The joint of the pipes was taken off to leak water. Tepco states, they are going to change the joint parts to the ones with bolt, made of polyethylene. The joint parts are made by kanaflex corporation co, used for every joint part of the pipes. There are a few thousands of joints in the site.

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.
