Fuel rod auto-loading apparatus for nuclear fuel assembly

A fuel rod auto-loading apparatus for a nuclear fuel assembly, which disposes fuel rods, each of which is assembled as a unit part, in a fuel rod case in a bundle to assemble the fuel rods into the nuclear fuel assembly, the fuel rod auto-loading apparatus comprising:

• a fuel rod storage unit having a plurality of racks stacked so that the fuel rods are horizontally stored;
• a fuel rod loading unit raised/lowered to the racks according to a bar code marked on each fuel rod and transferring the fuel rods, each of which is assembled as the unit part, and completes an acceptance test;
• a feeding unit horizontally placing the fuel rods in a row unit and loading the fuel rods into the fuel rod case in the row unit;
• a fuel rod unloading unit selectively unloading some specific fuel rods stored in the fuel rod storage unit and transferring the specific fuel rods to the feeding unit;
• a fuel rod assembly lifter which is disposed parallel to the feeding unit, and on which the fuel rod case is placed so as to be able to move upward or downward;
• and
• a controller controlling driving of the fuel rod loading unit, the feeding unit, and the fuel rod unloading unit.
