TEPCO reports another leak at Fukushima
The operator of the Fukushima Daiichi nuclear plant has reported another leak of radioactive water, this time from a steel storage tank above ground.
Tokyo Electric Power Company officials say a worker found the leak shortly after noon on Wednesday.
The tank is one of those built at the plant since May to store contaminated water transferred from storage pools underground.
The utility built the tanks after finding a series of leaks in April in the underground pools.
TEPCO officials say the contaminated water was seeping from a joint in the tank, at a rate of one drop every 3 to 4 seconds.
They report that bolts at the joint were tightened. They stopped water transfer and are investigating the cause.
The officials say no changes were detected in radioactivity levels at monitoring points near the plant.
The tank is about 400 meters from the sea. TEPCO officials say there is no risk of contaminated water reaching the sea.
