» TEPCO placed ice blocks in trenches to freeze radioactive water

TEPCO said that it has placed tons of ice blocks in underground trenches at the complex in an attempt to freeze highly toxic water pooled there, a step seen as necessary before constructing a 1.5-kilometer ice wall to prevent radioactive water from further increasing.

Amid concerns about the spread of ocean pollution by the toxic water, TEPCO is struggling with the unprecedented attempt to freeze 1.5-km of soil around basement areas of the Nos. 1 to 4 reactor buildings.

In April, TEPCO inserted frozen ducts in the trenches to try to freeze water but has failed to do so after more than three months.

According to TEPCO, a total of some 11,000 tons of highly toxic water has flowed into the trenches through the Nos. 2 and 3 reactor turbine buildings.

As an additional measure, TEPCO started putting 15 tons of ice per day into the trenches since late July, with the cumulative amount reaching 58 tons. But TEPCO is also not sure whether it will work or not.
