Kansai Electric's reactor shuts down 3 days after restart
FUKUI, Japan, Feb. 29, Kyodo
Kansai Electric Power Co. said Monday that a reactor at its Takahama nuclear plant shut down automatically after problems with a generator and a transformer triggered alarms, just three days after the reactor was rebooted.
The alarm was triggered when the power firm was preparing to start generating and supplying electricity after the No. 4 reactor in Fukui Prefecture reached criticality, or a state of sustained nuclear chain reaction, on Saturday following its restart the previous day.
The reactor was deactivated after the automatic alarm system prompted 48 control rods to be inserted. There is no problem with the reactor's cooling system and has been no environmental impact from the incident, the company said.
