A disassembly test machine using a cubic boron nitride (CBN) cutting-off wheel was designed and manufactured, and as a result of carrying out a disassembly test using a simulated fuel assembly based on the disassembly procedure, it was confirmed that the fuel assembly can be disassembled, and data for practical application were collected and problems were arranged.
