Here, sets of simulations of the main JT-60SA operation scenarios performed with the 0.5-D code METIS will be presented and discussed. METIS computes the time evolution of the global plasma quantities for given waveforms of the control parameters. It solves the current diffusion equation taking into account an approximate equilibrium evolution. Simplified treatment of the sources and of spatial dependences allow simulation of a discharge in a CPU time of the order of one minute, while keeping account of all the main non-linearities of the evolution. This approach allows completing the 0-D analysis with radial profiles and time evolutions. Evaluation of scalar parameters of a few JT-60SA scenario such as the normalized beta by METIS is found to be close those evaluated by ACCOME.
