DC performance and AC loss of cable-in-conduit conductors for International Thermonuclear Experimental Reactor

A reliable prediction of AC loss is essential for the application of International Thermonuclear Experimental Reactor (ITER) cable-in-conduit conductors (CICCs); however, the calculation of AC loss of ITER CICCs is a cumbersome task due to the complicated geometry of the multistage cables and the extreme operating conditions in ITER. In this paper, we described the models developed for hysteresis and coupling loss calculation, which can be suitable for the construction of ITER magnetic system. Meanwhile, we compared the results of theoretical analysis with the SULTAN test result to evaluate the numerical model we used. In addition, we introduced the n-value and AC loss with transport current for CICCs based on the DC measurement results at SULTAN, which lays the foundation for the further study.
