Fukushima Reactor 6 has lost 7 tons of water. Reactor 4 water pipes burst from being frozen
Tokyo Electric Power Company has found water leaks in 14 locations at the Fukushima Daiichi nuclear plant.
The utility says the leaks apparently occurred after frozen water ruptured the pipes and the leaked water did not contain any radioactive materials.
Tokyo Electric said about 40 liters of water leaked from a cooling system for a spent fuel pool at the No.4 reactor on Sunday, but the flow stopped when workers closed the valve.
The company said the leak forced the system to stop for one hour and 40 minutes, but the pool's temperature did not rise.
Tokyo Electric said 7 tons of water had leaked from the No.6 reactor.
The temperature fell to minus 8 degrees Celsius on Sunday morning near the damaged plant.
Ruptured pipes caused 3 water leaks on the previous day.
Tokyo Electric official Junichi Matsumoto admitted that the utility failed to take sufficient steps to prevent frozen pipes. He said it will take quick action to protect the pipes from the cold weather.
