  • Implementation of 3-D effects of the ITER plasma-facing components in a 2-D real-time model-based approach for wall heat flux control on ITER [Elektronski vir]
    Anand, H. ...
    A control oriented approach including the effect of 3-D geometry of the plasma-facing components for monitoring the power flux density, based on real-time equilibrium reconstruction for ITER has been ... successfully developed. The model-based approach, in the simplest case, describes the deposited heat flux as a poloidal flux function with two parameters to be specified by the modeler: the power exhausted across the plasma boundary and the scrape-off layer width. An additional module containing weighting factors accounts for the true 3-D geometry of the first wall panels. Integration of the 3-D effect is performed by using a new GUI interface, SMITER, hosting a magnetic field line tracing code and permitting import and appropriate meshing of full CAD descriptions of the plasma-facing components. The paper reports on the typical surface heat load distributions for the ITER limiter start-up plasma phase on an inboard midplane first wall panels with a double exponential radial heat flux profile, according to the findings of recent multi-machine studies of inboard limiter plasmas. Furthermore, it discusses the heat loads on the first wall during a vertical movement of the plasma in the ITER baseline scenario with the effect of ELMs on the radial profile of the parallel heat flux.
