The operator of the Fukushima Daiichi nuclear power plant has begun looking for new ways to reduce the amount of contaminated water that is hampering efforts to stabilize the damaged reactors.

Tokyo Electric Power Company sent a remote-controlled robot into the No.3 reactor building on Tuesday to take photos of the piping and measure radiation levels.

TEPCO decided to use the robot to find methods of cooling the nuclear fuel in the first 3 reactors with less water.

The utility injects about 390 tons of water into the reactors every day, but most of it becomes contaminated with radioactive materials.

TEPCO says the temperature of the No.3 reactor is relatively stable, but it needs more water than the others because of leaks and other problems.

Reducing the volume of contaminated water is the key to putting the reactors under control, but a system for treating radioactive water has been hit by a series of troubles.

TEPCO hopes to eventually send workers into the buildings to find a way to pour water directly onto the fuel rods.
