Abstract.  An overview is presented of the work performed over the last years at Politecnico di Torino in the field of thermal-hydraulic modeling of superconducting magnets for fusion, with particular reference to present International Thermonuclear Experimental Reactor (ITER)-related activities, and to future possibilities and needs. The two-fluid Mithrandir code and its multi-conductor version, the M&M code, are used together with the cryogenic network solver Flower. We discuss the capabilities of these validated tools to simulate the evolution of thermal-hydraulic transients characterized by widely disparate time scales, from heat slug propagation to quench, both in single dual-channel conductors like that of the QUELL experiment, and in the ITER model coils (central solenoid CSMC, toroidal field TFMC).
