Abstract.  The GLF23 and Multi-Mode (MMM) transport models are used along with models for the H-mode pedestal to predict the fusion performance for the ITER, FIRE, and IGNITOR tokamak designs. The drift-wave based predictive models GLF23 and MMM reproduce the profiles in the plasma core in a wide variety of tokamak discharges, even though they differ significantly in their response to temperature gradient (stiffness). Recent gyro-kinetic simulations of ITG/TEM and ETG modes have been used to renormalize the GLF23 model. The normalizing coefficients on the ITG/TEM modes are reduced by a factor of 3.7 and the ETG mode coefficient is increased by factor of 4.8 in comparison with the original model. The models for the pedestal temperature and density in type I ELMy H-modes are based on ballooning mode stability and theory-motivated scalings for the pedestal width. In these pedestal models, which were calibrated against more than 500 data points from the International Pedestal Database, the pedestal density is proportional to the average density and the pedestal temperature is inversely related to density. *Work supported by U.S. DOE grants DE-FG03-95ER54309, DE-FG03-92ER54141, DE-FG02-92ER5414.
