18,000 tons of radioactive water treated at Fukushima nuclear plant

The decontamination system co-developed by Areva and Veolia Water for the Fukushima Daiichi nuclear plant has just reached the milestone of 18,000 tons of highly-radioactive water treated to date, representing 15 percent of the accumulated volume.

The system was designed, constructed and launched in two months and is an essential element to stabilize the situation of the nuclear plants. It will improve the access of workers to strategic parts of the site and allow Tokyo Electric Power Co. to re-circulate the water that is used for cooling the reactors.

Constructed and commissioned by Areva and Veolia, the system reduces the water radioactivity level by a factor of 10,000 and can treat up to 50 tons of contaminated water per hour.

Altogether, more than 200 AREVA and 60 Veolia experts from France, Germany, the United States, Japan and Sweden were mobilized non-stop on this project.
