The operator of the Fukushima Daiichi nuclear power plant has suspended part of the activity of the radioactive water decontamination system as a liquid substance was found leaking from the device.

Tokyo Electric Power Company, or TEPCO, said that it stopped the system on Sunday morning. The liquid was found leaking from the hose for injecting chemicals to break down radioactive materials in the French-made device.

About 50 liters of liquid is believed to have leaked.

TEPCO said it is examining whether the liquid was the chemicals or radioactive water, as well as the cause of the leak. The company added that it is doing its best to resume the operation as soon as possible.

The system to recycle decontaminated water is the key to cooling reactors.

But TEPCO has to shut down the system frequently as it has been having continued problems since the start of its use on June 27th.

The utility has only one week left until July 17th, when it is scheduled to complete the first stage of the plan to bring the facility under control.

But the operating rate of the system during the week through last Tuesday was below the target, showing the difficulty the firm is facing.
