Seaside Trench Filled with Cement at Unit 3 of Fukushima Daiichi

On February 5, the Tokyo Electric Power Co. (TEPCO) began to fill the seaside trench of Unit 3 at the Fukushima Daiichi Nuclear Power Station with special cement (see photo).

The work was carried out as part of the larger project to remove the contaminated water that had accumulated there.

Contaminated water in trenches must be removed before frozen-soil shielding walls can be built. Similar work is underway at the Unit 2 seaside trench.

At Unit 3, TEPCO poured cement into the seaside trench right from the beginning as the first step – a change from the previous method. A total of one million cubic meters, as planned, was poured on the day.
