Available in PDF, EPUB and Kindle. Book excerpt: The evolution of the scrape-off layer (SOL) during a disruption in the DIII-D tokamak is modeled using the 2-D UEDGE transport code. The focus is on the thermal quench phase when most of the energy content of the discharge is rapidly transported across the magnetic separatrix where it then flows to material surfaces or is radiated. Comparisons between the simulation and an experiment on the DIII-D tokamak are made with the heat flux to the divertor plate, and temperature and density profiles at the SOL midplane. The temporal response of the separate electron and ion heat-flux components to the divertor plate is calculated. The sensitivity of the solution to assumptions of electron heat-flux models and impurity radiation is investigated.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores the possibility of performing in situ analysis for scrape-off layer plasma simulations (SOLPS). Since single SOLPS run can take up to several months and analysis proportionally long, the proposed solution promises considerable savings in analysis time and more eficient simulation runs. It alters the traditional three-step simulation approach by combining processing and post-processing into a single step. The solution extends existing B2.5 code with ParaView Catalyst co-processing library. The code uses the simulation data to create grid and attach associated field data in the VTK form that can be processed and displayed by ParaView. Co-processing is performed each time-step, thus allowing user to examine relevant data simultaneously while the simulation is running or prepare the data for post-processing in advance for the current and following runs. The implemented solution allows the user to perform analysis and debug simulation runs graphically, reduce disk usage and shorten combined simulation and analysis time without affecting simulation performance.

Available in PDF, EPUB and Kindle. Book excerpt: Damage to plasma-facing components (PFCS) from plasma instabilities remains a major obstacle to a successful tokamak concept. The extent of the damage depends on the detailed physics of the disrupting plasma, as well as on the physics of plasma-material interactions. A comprehensive computer package called High Energy Interaction with General Heterogeneous Target Systems (HEIGHTS) has been developed and consists of several integrated computer models that follow the beginning of a plasma disruption at the scrape-off layer (SOL) through the transport of the eroded debris and splashed target materials to nearby locations as a result of the deposited energy. The package can study, for the first time, plasma-turbulent behavior in the SOL and predict the plasma parameters and conditions at the divertor plate. Full two-dimensional (2-D) comprehensive radiation magnetohydrodynamic (MHD) models are coupled with target thermodynamics and liquid hydrodynamics to evaluate the integrated response of plasma-facing materials. Factors that influence the lifetime of plasma-facing and nearby components, such as loss of vapor-cloud confinement and vapor removal due to MHD effects, damage to nearby components due to intense vapor radiation, melt splashing, and brittle destruction of target materials, are also modeled and discussed.
