Mechanical test on the ITER CC and Feeder jacket

This paper focuses on mechanical tests on the ITER correction coils (CC) and Feeder jacket 316L stainless steel material. During manufacture, the conductor will be compacted and spooled after cable insertion. Therefore, sample jackets were prepared under compaction in order to simulate the status of conductor during manufacturing. Yield strength (0.2% offset), ultimate tensile strength, Youngʹs modulus and elongation at failure shall be reported. The mechanical properties of materials were measured at 300 K and low temperature (<7 K). The cryogenic test results show that the present jackets have very high properties. It is concluded that the results meet the ITER requirement.
