The operator of the Fukushima Daiichi nuclear power plant says a new method has failed to locate radioactive water leaking from one of the reactors. Identifying the leaks is a key step towards decommissioning the plant.
Tokyo Electric Power Company said workers used an infrared camera on Tuesday to search for the leaks in the suppression chamber at the No.2 reactor.
It was hoped that the infrared images would reveal the leakage spots by showing the temperature difference between the water and the air.
But the images failed to show a big gap in temperatures.
TEPCO says it will devise other ways to find the locations.
The utility has been injecting water into the reactor to cool melted fuel rods to prepare for their removal. But some of the radioactive water is leaking from unidentified places.
