Manufacture and Acceptance Test of the Full Size ITER PF5 Conductor Sample
In the R&D; process of the International Thermonuclear Experimental Reactor (ITER) Poloidal Field (PF) coils, 16 m PF5 Cable-in-Conduit Conductor (CICC) was integrated at Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). The manufacture process of the qualification conductor was according to the ITER design. As required by the ITER Procurement Arrangement (PA), full size PF5 qualification conductor sample was manufactured and delivered to SULTAN facility (CRPP Villigen, Switzerland) for acceptance test. The PF5 conductor sample was made of two legs by one conductor bending, bottom hairpin box, upper terminations, support clamps, insulation, cryogenic piping and instrumentations. The concept of hairpin box and comb-type terminations configuration for ITER PF conductor sample which was co-contributed by ENEA and CEA was successfully verified by the first China PF2 conductor sample tested in SULTAN facility May 2010. The PF5 conductor sample test was initiated at the end of Feb. 2011. The test program included DC performance, cyclic loading, AC loss and MQE test. The conductor manufacture process, conductor sample assembly and test results were presented in this paper.
