TOKYO (AP) —
Power has been restored to a cooling system at a tsunami-damaged nuclear plant in Japan, after failing for the second time in a month.
The operator of the Fukushima Dai-ichi plant says power for the cooling system for a storage pool for fuel was restored after a two-hour break at reactor No. 3. Tokyo Electric Power Co. says there was no immediate danger from the breakdown, and that the cooling system can be turned off for two weeks before temperatures approach dangerous levels at the spent fuel storage pools.
The utility says work to put up nets to keep out rats and other animals at the plant in northeastern Japan inadvertently caused the power outage, and it's still under investigation.
A rat found dead near a switchboard is suspected of also causing the power outage last month that led to a cooling system not working for two days.
