The company's nuclear reactors have gradually gone offline amid public safety concerns in the wake of the Fukushima nuclear disaster in March 2011, with the last active one shut for a scheduled inspection on Monday. More than 40 percent of the firm's output had previously came from nuclear power, the Nikkei said, adding that despite the loss Kansai Electric is expected to maintain its annual dividend of 60 yen a share. The company will issue its financial year outlook as early as next week, Nikkei said.
