JSME construction standard for superconducting magnet of fusion facility "Fabrication, installation, NDE and testing"

Nakahira, Masataka*; Niimi, Kenichiro; Irie, Hirosada*

A standard of fabrication, installation, NDE and testing for superconducting magnets for fusion facility was developed. For construction of TF coil, a "Fabrication and Installation" standard FM-4000, accompanying a mandatory Appendix 41 "Welded Joint" and a "Nondestructive Examination" standard FM-5000 accompanying a mandatory Appendix 51 for "Ultrasonic Examination Method" and a "Pressure and Leak Testing" standard FM-6000 have been developed, based on other JSME standards for nuclear power plant (JSME S NB1) and also ASME Sec.III ND, NF or Sec.VIII-div.2 Since TF coil structure does not include radioactive materials but is operated under high stress produced by high magnetic field, it is not safety-relevant-barrier. The requirements to construction should be relaxed comparer with a fission reactor.
