Tokyo, Aug 22 (EFE).- The operator of the Fukushima nuclear power plant began Tuesday to complete the freezing of the wall around the damaged reactors to prevent the leaks of radioactive water.
Tokyo Electric Power Company (TEPCO) opened the valves to circulate a coolant to freeze the remaining five percent wall area, a company spokesperson told EFE.
The complete perimeter of the wall (1.5 kilometers/0.9 miles) is expected to be sealed to prevent holes or leaks by autumn in a process that began in Mar. 2016.
The ice wall, created by the frozen soil around the four reactors affected by the Mar. 2011 earthquake and tsunami, would prevent underground water from mixing with radioactive coolant in the reactors' interior and leaking into the Pacific Ocean.
According to TEPCO, 400 tons of water had seeped through the complex's interior, although it reduced to about 120-130 tons this year.
The company aims to reduce the leaks to less than 100 tons a day once the freezing mechanism is completely functioning.
More than 1,500 pipes have been planted in the soil at depths of 30-35 meters (98-115 feet) around the four reactors in order to allow minus 30 degrees Celsius (minus 22 degrees Fahrenheit) saline solution to circulate and form a frozen barrier around it. EFE
