Cooling systems on the Fukushima Daiichi nuclear power plant suffered a power outage yesterday, plant operator Tepco has confirmed.
At 6.57pm 18 March local time power supplies at the facility’s main anti-earthquake building stopped. This led to the suspension of units one, three and four of the spent fuel cooling systems.
Unit one has since been restored and units three and four are expected to be restored by Tuesday evening.
Tepco is in the process of decommissioning Fukishima Daiichi nuclear power units one to four to allow evacuees to return to their homes after the 2011 earthquake.
The magnitude 9.0 earthquake and subsequent 14m high tsunami on 11 March 2011 flooded the Fukushima nuclear power station in north eastern Japan, triggering a meltdown and the evacuation of 150,000 people.
