The operator of the Fukushima No. 1 nuclear power plant is grappling to locate the source of a leak of highly radioactive water in the crippled No. 2 reactor, and will continue trying to pinpoint the cause next week.
A remote-controlled robot is now scouring the basement of the reactor building that houses the pressure suppression chamber to pinpoint the cause of the leak.
Tokyo Electric Power Co. said it was unable to identify the source of the leak when the robot inspected one of the eight vent pipes that connect the chamber with the containment vessel on Dec. 11.
