Understanding transport of deuterium and tritium
In this PhD dissertation, integrated modelling of multiple ion plasmas is studied. Understanding the transport of deuterium and tritium is essential to predict and inform the control of the fusion burn. Multiple impurities will unavoidably be present in the plasma and the scope of their impact ranges from plasma performance and heat exhaust to disruptivity and helium accumulation. Self-consistent modelling of impurities provides useful insight in such processes. The main tools utilized are the integrated modelling suite JINTRAC, with first-principle-based QuaLiKiz as the reduced turbulent transport model, and the high-fidelity gyrokinetic code GENE for targeted validations. The overarching strategy consists of observing a phenomenon in experiments, reproducing it within integrated modelling, identifying the crucial physics underlying the observations and validating it with higher fidelity standalone modelling.
