Abstract
Within the framework of a R and D program on the possible configuration of the superconducting cable that can be used on the NET (Next European Torus), ENEA (Italian Commission for Nuclear and Alternative Energy Sources) has decided to start the project of a model coil using CICC (Cable-In-Conduit Conductors) turns. The CICC is a cable configuration (HOENIG,1985) first utilized by Westinghouse for the construction of one of the six coils of LCT (Large Coil Task). The ENEA CICC will be composed of 135 Nb3Sn strands (each of them with 19 wires) sandwiched between two Cu+CuSn stabilizing elements, clamped on a copper tube, encased in a steel jacket and filled, during operation, with supercritical helium at 4.5 K and 0.8 MPa. This paper describes the stress analysis of the superconducting coil under the effect of Lorentz forces. Due to the high number of turns (286) in the coil and the conductor complexity (geometry, materials, and loads), the analysis was performed by taking advantage of the SUPERELEMENT code option recently introduced in the 4.7 ABAQUS version. The results of this analysis are compared with the results obtained using ordinary material homogenization techniques.
