[en] This study develops a simple transport model which can be used predictively for tokamak negative central shear (NCS) modes, with the assistance of Lawrence Livermore National Laboratory's core plasma simulation code, CORSICA. The results show that the the Rebut-Lallia-Watkins Critical Electron Temperature Gradient Model, coupled with an NCS transport model and TRANSP data, renders a reasonably close match to experimental temperature profiles. Additionally, this research offers the first benchmark calculation indicating that the CORSICA code itself, when given transport coefficients from the analysis of experimental data, replicates the experimental profiles, indicating that both TRANSP and CORSICA together are consistent in their analysis of the plasma evolution. This means CORSICA is working properly and has no known major internal flaws. 14 refs., 12 figs
