Design Features of a Spent Fuel Transfer Device between Spent Fuel Storage Pools in NPPs

This paper introduces the SFTD which will be newly applied in domestic nuclear power plants, and describes its design features including plant arrangement, component layout and sequences of fuel transfer. As described above, the SFTD is developed to allow the underwater transportation of spent fuel assemblies between spent fuel storage pools, and is also planned to be applied for domestic nuclear power plants being under construction. Through the SFTD, the spent fuel can be transferred easily and stably to a designated location while maintaining its vertical position within the refueling canal. It is expected that the SFTD can be useful equipment for transferring the spent fuel between spent fuel storage pools
