Power restored at Fukushima NPP

Cooling systems were restored for four fuel storage pools at Japan’s tsunami-damaged nuclear plant, more than a day after a power outage halted the supply of fresh cooling water and raised concerns about the safety of the facility.

Tokyo Electric Power Co. said the cooling system at the last pool at the Fukushima Dai-ichi plant was repaired early Wednesday. It said pool temperatures were well within safe levels and the reactors were unaffected.

TEPCO spokesman Yoshikazu Nagai said workers were still trying to determine the cause of the cooling failure, which began when a brief power blackout hit the plant Tuesday evening.
