A reactor at the Takahama nuclear power plant in central Japan has shut down automatically due to a malfunction, 3 days after it was restarted. Kansai Electric Power Company, operator of the plant in Fukui Prefecture, says an alarm indicating trouble inside the generator at the No.4 reactor went off shortly after 2:00 PM on Monday. The turbine and reactor then automatically deactivated. The utility says the trouble occurred during ongoing work to send power to the grid by connecting the generator to the transmission facility in the central control room.
