At the Fukushima NPP, a hundred tons of radioactive water leaked
The operator of the Japanese nuclear power plant "Fukushima" reported that a leak of one hundred tons of radioactive water was found at the emergency station.
The leak occurred from one of the tanks, where the water used to cool the emergency reactors was stored. The beta-radiation level of the water contained in such a reservoir is "230 millions of becquerels per liter," representatives of Tepco said.
One of the reasons for the incident could be that the reservoir was filled to capacity with radioactive water. And this is one of the most acute problems at the nuclear power plant "Fukushima-1". Now about 440 thousand tons of contaminated liquid have accumulated in underground rooms and tanks. According to experts, in the technical tunnel of the station - another 15 thousand tons. The volume of polluted water in underground rooms is constant grows due to the groundwater coming from the hill.
The accident at the Fukushima-1 NPP occurred in March 2011, amid an earthquake and tsunami. The reactor cooling system was out of order, and the fuel rods overheated. Initially, sea water was used to cool the reactors, which was drained back into the ocean, but then special tanks were equipped for the polluted water. However, radioactive water was already repeatedly leaking from these tanks.
The deadline for eliminating the consequences of the accident at the Fukushima NPP is tentatively estimated at least in 40 years.
