The cesium-absorption unit uses technology supplied by Kurion and France’s Areva

Kurion supplied the cesium-absorption unit which needed replacement, as the radiation levels rose faster than expected at 4.7 millisieverts.

TEPCO deployed the unit as part of its plan to reduce the amount of radiation in about 28 million gallons of water in basements and trenches at the nuclear plant, reports Bloomberg.

The volume of contaminated water is expected to double by the end of the year, Tepco however did not disclose when it plans to restart the system.
