The report claimed that an official of the Nuclear and Industrial Safety Agency said the crane “didn’t fall, and that safety at the nuclear plant has been maintained.”

It is understood that the crane is located on the fourth floor of the building that houses the nuclear reactor and is designed to lift the lid of the nuclear reactor’s pressure container. The lid of a pressure container and a pool for spent nuclear fuel are located below the floor. A joint in the crane was apparently damaged in the quake.

The report concluded: “The No 6 reactor was not in operation when the earthquake hit Niigata Prefecture and nearby areas on July 16.”
