ABSTRACT:
An apparatus incorporating a microprocessor control is provided for automatically loading nuclear fuel pellets into fuel rods commonly used in nuclear reactor cores. The apparatus comprises a split "V" trough for assembling segments of fuel pellets in rows and a shuttle to receive the fuel pellets from the split "V" trough when the two sides of the split "V" trough are opened. The pellets are weighed while in the shuttle, and the shuttle then moves the pellets into alignment with a fuel rod. A guide bushing is provided to assist the transfer of the pellets into the fuel rod. A rod carousel which holds a plurality of fuel rods presents the proper rod to the guide bushing at the appropriate stage in the loading sequence. The bushing advances to engage the fuel rod, and the shuttle advances to engage the guide bushing. The pellets are then loaded into the fuel rod by a motor operated push rod. The guide bushing includes a photocell utilized in conjunction with the push rod to measure the length of the row of fuel pellets inserted in the fuel rod. Safeguards are employed to insure that the weight and position of the fuel pellets within the fuel rod fall within certain prescribed limits. After a segment of fuel pellets has been loaded, the guide bushing disengages the fuel rod, the rod carousel transfers a new rod into position, and the entire loading operation is repeated.
