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.

Light-water reactor nuclear fuel rod loading force measuring apparatus

Provided is an apparatus for fatigue testing a bulge tool having a WH-type skeleton, the apparatus including: a fixing bracket having tool holes penetrated through opposite sides thereof; a tool housing coupled to the tool hole of the fixing bracket and having the bulge tool inserted and installed therein; a moving rail installed at one side of the fixing bracket in a lengthwise direction of the tool housing and providing a reciprocating movement path facing the tool housing; a moving bracket reciprocating along the moving rail; a pusher protrudingly installed from the moving bracket toward the tool housing and moving in and out of the bulge tool; a measurement means installed between the pusher and the moving bracket, measuring a load applied to the bulge tool; and a drive means for generating power reciprocating the moving bracket on the moving rail.
