Tepco is planning to cover the bottom of sea with solidifying clay


In the press conference of 1/24/2012, Tepco announced they are going to solidify the bottom of sea with the mixture of clay and concrete.

They are planning to start it from early February, end it by April.

It is not to spread concrete to cover the sea ground but cover it with heavy clay slowly so hot particles in the sea will not come up.

The areas around intake of reactor 1 ~ 6 will be covered.

They still have not assessed the influence for the marine environment.



After the press conference, MEXT released the data of contamination level on of sea ground.

Ag-110m has been measured constantly from December.



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.
