One hundred tonnes of highly contaminated water has leaked out of a tank at the Fukushima nuclear plant, the worst incident since last August, when a series of radioactive water leaks sparked international alarm.
Tokyo Electric Power Co told reporters the latest leak was unlikely to have reached the ocean. But news of the leak at the site, devastated by a 2011 earthquake and tsunami, further undercut public trust in a utility rocked by a string of mishaps and disclosure issues.
"We are taking various measures, but we apologise for worrying the public with such a leak," said Masayuki Ono, a spokesman for the utility, also known as Tepco.
"Water is unlikely to have reached the ocean as there is no drainage in that tank area."
Tepco said water overflowed from a large storage tank at the site late on Wednesday after a valve had remained open by mistake and sent too much contaminated water into a separate holding area.
