This water tank is located in the west of the immune system. Results of the analysis of polluted water between the internal and external waterproofing sheets showed a radioactive concentration of about 6,000 becquerel / cm ³ .

Because this polluted water is water after it has been abolished ceasium, TEPCO thinks that 'the level of environmental impact is low'.

According to TEPCO, the 14,000-ton radioactive water tank is now full of water. Because the structure is half underground, the underground surface of the tank is lined with 3 layers of waterproofing to prevent water leakage into the ground.

The leak is thought to have happened around 10 am April 5.

Also at this power plant, the amount of polluted water remains 260,000 tons. In the factory there are about 7 water tanks like this and the leaked tank this time began to be used in February.

TEPCO believes that because the preservation of polluted water has now reached its limit, the factory is considering the possibility of discharging treated water to the sea.
