    The COMPASS tokamak, a mid-sized flexible device with ITER-like shape, which can operate in H-mode, is starting its re-established operation at the Institute of Plasma Physics in Prague. A new 600kW, 40 keV neutral beam injection (NBI) system is foreseen as a major upgrade. Reported here are predictive simulations with the ASTRA transport code, in which the FAFNER Monte-Carlo NBI code is, for the first time, self-consistently integrated. These simulations are carried out for several typical COMPASS scenarios with different magnetic fields, plasma currents and shapes. We compare ohmic scenarios with NBI-heated scenarios and show that NBI is able to significantly improve the plasma performance, particularly to attain Ti~=Te, which is the primary goal of the NBI system. The NBI performance is discussed in detail. The chosen energy of 40 keV is shown to be in many aspects optimum.
