The TETRA tokamak systems code is used to compare designs for the International Thermonuclear Experimental Reactor (ITER) that use Nb{sub 3}Sn and NbTi superconductor magnets. Similar minimum-cost devices are found with both types of conductors when superfluid helium (He-2) is used in conjunction with the NbTi. The cost of using NbTi with He-1 cooling is much higher than that of using Nb{sub 3}Sn or NbTi with He-2 cooling. Generally, the minimum-cost devices occur for peak fields at the toroidal field coil of about 11.5-13 T, depending on the physics requirements. Sensitivities to the allowable stress level indicate strong cost increases when the stress is reduced from the nominal 600-MPa level and weaker cost benefits when the stress is allowed to reach higher levels. 8 refs., 5 figs., 1 tab.
