A new water leak, possibly from the effort to cool a crippled reactor, has been detected on the first floor of a reactor building at the Fukushima No. 1 nuclear power plant, Tokyo Electric Power Co. said Jan. 18.
TEPCO said workers discovered by a video feed that water was leaking on the first floor of the wrecked No. 3 reactor building earlier in the day.
The utility added that the water was flowing into the basement of the reactor building and not outside the structure. It is investigating the source of the leak.
TEPCO suggested the possibilities that the water was leaking from a pipe that is sending cooling water to the reactor or from the reactor containment vessel.
