Tokyo, Sept. 4: Japan has announced it will spend an estimated 473 million dollars to build a “ice wall” around the Fukushima nuclear plant to stop radioactive water leaks into the Pacific Ocean.
Senior official Yoshihide Suga said the leaks from the crippled nuclear plant are getting worse and this has convinced the government to intervene, BBC reports.
The wall of frozen earth will be created around reactors using pipes filled with coolant to prevent groundwater coming into contact with the contaminated water.
Suga also said the water treatment systems will be upgraded to tackle the build-up of contaminated water.
The plant was crippled by the March 11, 2011 earthquake-cum-tsunami that knocked out the reactors cooling systems, leading to the meltdown of at least three of them.
The Tokyo Electric Power Company (Tepco) had started storing contaminated water to cool the reactors, but the storage of large quantities has proved a challenge for the company, the BBC report added.
The number of storage tanks has been increased over the years by TEPCO, but reports of fresh leaks from the pipes has raised concern of radioactive water seeping into the ground.
Japan’s nuclear regulator had last month raised the severity level of radioactive water leak at Fukushima to three on the seven-point International Nuclear and Radiological Event Scale (INES). (ANI)
