The operator of the crippled Fukushima Daiichi nuclear power plant says it may take several days before a system to decontaminate highly radioactive water accumulating in the facility can be restarted.

Tokyo Electric Power Company put the system into full operation on Friday night, but had to halt it 5 hours later as the radiation level of a cesium absorption device rose higher than expected.

The device is also designed to remove oil and technetium.

TEPCO says it may have absorbed larger-than-expected amounts of radioactive materials along with oil. The utility is now working on measures to solve the issue.

TEPCO says the effort will require time. In addition, depending on the situation, it may have to reconsider the working of the entire system and examine the effect of radioactivity emitted from nearby pipes.

There are concerns that the highly radioactive water may overflow in around one week if no measures are taken.
