Construction work for "ice wall" at Fukushima plant to start Mon.
TOKYO, May 30, Kyodo
The operator of the crippled Fukushima Daiichi nuclear power plant said Friday it plans to start building a huge underground ice wall around four reactor buildings on Monday as a step to address the toxic water buildup at the plant.
The announcement was made after Tokyo Electric Power Co. and general contractor Kajima Corp. were able to convince nuclear regulators that the unprecedented project will not trigger significant sinking of the ground supporting the buildings.
Under the government-funded project, 1,550 pipes will be inserted deep into the ground to circulate coolant and freeze the nearby soil. The ice wall is expected to prevent groundwater from becoming heavily contaminated by seeping into the buildings.
