Japanese electronics maker Toshiba has developed a system to decontaminate radioactive wastewater at the Fukushima Daiichi nuclear power plant from early August.

The system, nicknamed Sarry, was shown to media at a plant in Yokohama on Thursday. It consists of a series of 14 tanks, each 1.4 meters wide and 3.6 meters high.

Minerals put inside the tanks are to absorb radioactive cesium and strontium and reduce levels of radioactivity in contaminated water by a factor of about one million.

A decontamination system in place at the Fukushima plant since June has been accident-prone and running at 73 percent capacity, far below the target of 90 percent.

The new equipment is expected to be used in parallel with or as a supplement to the existing one.

A Toshiba official says the firm made the new system simpler than the existing one by studying problems it developed.
