  摘  要:

  Integrated modeling is an essential activity which ensures the right understanding of multiscale (in space and time) magnetically confined plasmas.  The essential physics that such activity must address is heat and particle transport, heat and particle sources, heating  and current drive, plasma equilibrium or current diffusion.A significant effort has been carried out in CEA/IRFM towards this direction since many years ago. For that purpose, the coupling of codes covering multiscale physics into a transport solver  lead to the creation of the CRONOS suite of codes, which has been an international reference in the integrated modeling domain. This activity has been particularly useful for predicting ITER and DEMO future plasmas, analyzing turbulent transport in different tokamaks such as JET or analyzing the synergy between different heating mechanisms.

  In addition to this activity, and with the aim of speeding-up the calculations while maintaining a similar level of physics detail, several techniques have been applied   such as the creation of neural networks for the quasi-linear code qualikiz (also developed in CEA/IRFM) or the creation or a simplified 0.5 version of CRONOS called METIS.An evolution of CRONOS is now being developed in the framework of an EUROfusion/ITER collaboration: Integrated Modelling Analysis Suite (IMAS) which will heritage not just the main CRONOS features but as well the that of many other different codes worldwide used.

  The possibilities for modelling EAST and CFETR will be discussed
