  • Patent number: 12159725
    Abstract: A light-water reactor nuclear fuel rod loading apparatus, which comprises a spacer grid holder and a loading power device installed with a traction module configured to reciprocally move toward the spacer grid holder. The loading apparatus further comprises a hollow cladding tube sample and a pulling bar comprising one end part and an opposite end part. The one end part passing in use through a cell of a spacer grid held by the spacer grid holder and configured to couple to the hollow cladding tube sample. The opposite end part is coupled to the traction module. The loading apparatus further comprises: a measuring device installed on the pulling bar and configured to measure loading force of the traction module loading the pulling bar; a holder cap; and a holder comprising an end part configured to in use pass through the cladding tube sample and couple to the holder cap.
