Abstract.  Resistive pressure-gradient-driven turbulence (RPGDT) and ion-temperature-gradient-driven turbulence (ITGDT) seem to play a critical role in explaining the measured transport in tokamaks. The former at the plasma edge, and the latter at the plasma core. However, numerical calculations based on these types of instabilities have been limited to flux tube geometry or limited by numerical resolution. Here, we present results for three-dimensional calculations in the full torus geometry.
