Japan will shut down another of its nuclear reactors leaving only eight of the resource-poor country's 54 reactors in operation.
Kansai Electric Power, operator of the Mihama Nuclear Power Plant in Fukui, western Japan, announced on Wednesday that operations at its number two reactor will be suspended manually due to cooling water valve problems.
Once the plant is suspended, only 15-percent of the country's nuclear energy capacity will be in operation amid fears over the safety of nuclear power in Japan.
The country previously depended on nuclear energy for a third of its electricity needs.
Meanwhile, rice containing radioactive cesium above the government's safety limit has been detected in another city in Fukushima Prefecture showing that a wider area of the northern Japan prefecture has been affected after the nuclear accident in March.
