Japan pauses world's largest nuclear plant hours after restart
Japan suspended operations at the Kashiwazaki-Kariwa plant, the world's largest by capacity, just hours after restarting reactor six when an alarm sounded during start-up; Tepco says the reactor is stable with no radiological impact outside the plant and is investigating the cause. The seventh reactor is not expected to resume until 2030, and five other reactors could be decommissioned, leaving far less capacity than before Fukushima.
