  "account": "On August 9, Kansai Electric Power Co.'s Oi nuclear power plant near Fukui Prefecture in central Japan experienced an automatic shutdown of its No. 3 reactor. The incident occurred around 11:55 p.m. Saturday when an alarm sounded, indicating an abnormality in a device responsible for generating a magnetic field connected to the reactor's power generator, which is linked to a turbine. Kansai Electric reported that both the power generator and the reactor ceased operations automatically upon receiving the alarm. The plant has been operational for 35 years, with a planned regular checkup set to commence in October. Notably, a similar issue with a comparable device led to the automatic shutdown of the No. 2 reactor's power generator and the reactor itself at Kansai Electric's Mihama nuclear plant in Fukui in April 2000. As of now, the cause of the latest incident is under investigation, but no leakage of radioactive substances has been detected. The reactor in question is currently undergoing decommissioning.",
