A spray pump, that was about to be shipped off to Vietnam, is instead being used at Fukushima Daiichi nuclear plant.

The Vietnamese company that bought the pump, gave Japan permission to use the pump to help fight the nuclear disaster.

The pump is designed to pour concrete for construction of high rise buildings. It is equipped with a 50 meter (175 feet) arm, and can accurately reach targets from a distance. It is being used on reactor 4.
