We present calculations of ionization balance and radiative power losses for tungsten in magnetic fusion plasmas. The simulations were performed within the framework of Non-Local Thermodynamic Equilibrium (NLTE) Code Comparison Workshops utilizing several independent collisional-radiative models. The calculations generally agree with each other; however, a clear disagreement with experimental ionization distributions at low temperatures 2 keV<T{sub e}<3 keV is observed. Comparison is made with other calculations. The obtained results can be used in planning new experiments in magnetic confinement fusion.
