Fast Ions and the Integrity of the ITER First WallDoc. Taina Kurki-Suonio Aalto University taina.kurki-suonio-miumau-hut.fi The overall goal of the project is to ensure that the final design of the ITER first wall will be free of any known weaknesses as far as energetic particles and hydrocarbons containing tritium are concerned. This can be accomplished by providing the international fusion community with true-to-life quantitative predictions of fast ion power loads to the wall and by resolving the unknown mechanisms related to impurity migration at the tokamak edge. Realistic fast ion power loads can only by obtained by true 3D simulations that also include transport due to microturbulence and MHD activity. The subtleties of carbon transport will be addressed with new simulation tools that avoid the shortcomings of the fluid approach usually applied to this problem. The primary research tool is The detailed goals of the ASCOT Upgrade research programme are: - developing numerical models to account for fast ion transport due to turbulence and various MHD phenomena - validating the numerical models against experimental results in JET and AUG tokamaks- predictive simulations of fusion alpha and NBI ion wall power loads for different ITER scenarios - international networking and researcher training: experiments at - raising the public awareness on energy issues and on fusion in particular The code development efforts are expected to make the |
