Tokyo Electric Power Company retrieved the debris removal device that was used at  Fukushima Daiichi nuclear power plant.

TEPCO retrieved the device on September 25, a week after the camera mounted on the device stopped working, forcing the operator to suspend the debris removal process.

The operator believes there was a defect in the camera, and said it will further investigate the matter.

It has not been able to set a date for the resumption of the debris removal work.
