TRANSP - TGLF predictions for ITER*

The GLF23 [1] and TGLF [2] quasilinear gyrofluid transport simulation models have been installed in TRANSP for analysis of experiments and for generating self-consistent integrated predictions [3]. A new parallel module PT-SOLVER was developed [4] for efficient solution of these and other numerically challenging transport models. A new spectral shift paradigm was added to TGLF [5] to strengthen the physics basis of toroidal rotation and flow shear simulations. Predictions of density, temperatures, and toroidal rotation are being verified and validated [6,7] with experimental data from JET and DIII-D. Verification and validation results, and predictions for ITER H-mode and hybrid plasmas are given. The ITER predictions are compared with previous TRANSP predictions [8] using the GLF23 model.\\[4pt] [1] R. Waltz, {\it et al.,} Phys. Plasmas {\bf 4} (1997) 2482\\[0pt] [2] G.M.
