The University of Illinois hydrodynamic burn code, AFBURN, has been used to model the performance of homogeneous D-T, D2, and catalyzed deuterium ICF targets. Yields and gains are compared for power-producing targets. AFBURN is a one-dimensional, two-temperature, single-fluid hydrodynamic code with non-local fusion product energy deposition. The initial conditions for AFBURN are uniformly compressed targets with central hot spots. AFBURN predicts that maximum D2 target gains are obtained for target ρR and spark ρR about seven times larger than the target and spark ρR for maximum D-T target gains, that the maximum D2 target gain is approximately one third of the maximum D-T target gain, and that the corresponding yields are approximately equal. By recycling tritium and 3 He from previous targets, D2 target performance can be improved by about 10%.
