An incident occurred in the course of the work on 22 September when a truss about seven metres long and weighing about 470 kilograms slipped into the fuel pond during remote cutting and handling.
Tepco said that efforts to remove a truss near the pond had been halted when the contractor carrying out the work realised it was connected to other adjacent pieces of steel which could not be cut. Tepco noticed that the truss had moved into an unstable position, with half of it already the fuel pond. It was decided to lift the piece away, but the tips of hydraulic forks touched the piece and it slipped all the way into the pond.
An underwater video inspection on 25 September showed the beam lying on top of dust-covered fuel racks having caused no apparent damage.
