The power failure did not cause an accident, but a report by the International Atomic Energy Agency in Vienna discovered that senior engineers from Korea Hydro and Nuclear Power, which runs the reactor, had neglected the safety problems for more than a month after the loss of power. In June, after a safety check, the IAEA gave the green light for Kori-1 to resume operation. Korea’s Nuclear Safety and Security Commission (NSSC) approved the restart on 4 July, but activists and local residents remain strongly opposed to restarting the reactor. At first, the Korean Ministry of Knowledge Economy, which oversees energy policy, had said that the restart would be delayed to alleviate anxiety. But the government changed its mind as a result of a nationwide heatwave that has put a strain on the country’s electricity supply in recent days."
