‘The leak was the second one reported in the last few weeks. In late April, a still-unexplained power outage caused water transfer pumps at the plant to shut down. The pumps were being used to move radioactive water from one drainage channel into another after it was revealed that water had been spilling from the first channel directly into the Pacific Ocean.
When the power to the plants shut down, radioactive water resumed flowing into the sea. Approximately 100 tons of contaminated water — also exceeding the legal limit — are estimated to have escaped before power was re-established.’
