Radioactive water leaks from plant
The operator of Japan's crippled nuclear power plant has revealed that highly radioactive water leaked from a purification device over the weekend, and some may have drained into the ocean.
The leak came as Tokyo Electric Power aims to bring the damaged Fukushima Dai-ichi plant to a cold shutdown by the end of the year.
A pool of radioactive water was discovered around a decontamination device, the firm said in a statement. After the equipment was turned off, the leak appeared to stop.
Later, workers found a crack in a concrete barrier leaking the contaminated water into a gutter that leads to the ocean.
The company estimates that about 300 litres leaked out before it was blocked with sandbags.
Officials were checking whether any water had reached the ocean.
