Tokyo Electric Power Co. removed a steel beam from a spent nuclear fuel pool on Thursday at the crippled Fukushima Daiichi nuclear plant, using a remote-controlled crane, the utility said.
The 7-meter steel beam weighing 470 kilograms dropped into the water-filled pool in the No. 3 reactor building in September when the plant’s operator TEPCO used a similar crane to remove debris from the upper portion of the building.
Another steel beam was found during a later camera survey in addition to a 30-ton fuel exchanger and concrete pieces, which dropped into the pool when a hydrogen explosion occurred at the building after the March 2011 earthquake and tsunami crippled the plant.
