Basements of Fukushima with radioactive water

The Fukushima nuclear power plant continues to sow concerns. The last bad news put forward by TEPCO, the company that runs the plant, has to do with the radioactive contamination of the waters.

Let's see what's happening in the basement of the reactor number 1: a stream of underground water enters the basement of the building and get contaminated.

It is estimated that every day, 400 cubic meters of water entering the structure and mingle with the cooling system of the reactors. The water infiltrates in the basement of buildings after having been in contact with the nuclei of the reactors partially fused.

Fukushima is about 400000 tons of water laden with caesium, strontium and tritium in basements or stored in special tanks.

To try to block the entrance of groundwater in October will begin a test on the ground next to the reactor number 4.

This is to introduce metal pipes to 30 meters deep and pumping sodium chloride 40 degrees below zero, to freeze the earth around.

Japanese Industry Minister predicts end in March 2015 test and power, then build this subterranean ice wall to isolate the groundwater and central Pacific Ocean.

The cost of the works to contain the leaks is estimated at 357 million euros. The sum was approved this week by the Japanese Government: "Until now, a lot of the work has been responsibility of TEPCO. Further, if the State of emergency, the Government takes the lead and will implement all the necessary budgetary measures. We want to speed up the work that has to be done ", ensures the Minister Toshimitsu Motegi.

The Nuclear Regulatory Authority of Japan criticized the TEPCO and stated that the measuring instruments and of communication from the company are highly inappropriate and confusing.
