Cooling Restored at Fukushima Daiichi Nuclear Power Station
Japan's Nuclear Regulation Authority (NRA) has informed the International Atomic Energy Agency that cooling systems at all spent fuel pools at the Fukushima Daiichi Nuclear Power Station have resumed operation.
This follows a power outage that began at 19:00 local time on 18 March 2013, disabling spent fuel cooling systems at Units 1, 3, and 4 and the Common Spent Fuel Pool.
The NRA said the cooling system at Unit 3 was restored at 22:43 local time on 19 March, and at the Common Spent Fuel Pool at 00:12 on 20 March.
The systems at Unit 1 and Unit 4 were restarted earlier on 19 March.
The operator, Tokyo Electric Power Company, continues to investigate the cause of the power outage.
