Mainichi (Kyodo)| April 21, 2015
TOKYO (Kyodo) — Tokyo Electric Power Co. said Tuesday it has found all of the eight water transfer pumps halted at its stricken Fukushima Daiichi nuclear power station, leaving radiation-contaminated water to leak into the Pacific Ocean.
The utility is now checking why the pumps for a drainage path have stopped and how much water has leaked into the ocean.
TEPCO began to pump up contaminated water from the path only last Friday, after finding in late February that radioactive water was continuing to leak from the path into the ocean, following the March 2011 earthquake-tsunami disaster that devastated the plant.
The pumps, designed to move contaminated water from the path to another one that leads to a bay facing the station surrounded by fences, were confirmed to be working Monday afternoon but found stopped at 8:45 a.m. Tuesday.
The utility unveiled earlier this year that it had found water samples from the drainage last May containing more radioactive materials than the legally allowable limit.
