COUPLED CORE AND EDGE IMPURITY MODELLING IN HIGH-RADIATION- FRACTION TOKAMAK SCENARIOS
DIFFER (Dutch Institute for Fundamental Energy Research) is one of the NWO institutes and focuses on a multidisciplinary approach to energy research combining physics, chemistry, engineering and materials science. The institute is based on two main strands, solar fuels for the conversion and storage of renewable energy and fusion energy as clean and unlimited source of energy. DIFFER is developing and supporting a national network on fundamental energy research and is closely collaborating with academic institutions, research institutes and industry.
This project focuses initially on JET modelling using the JINTRAC suite of codes. JINTRAC combines core transport with semi-empirical or first-principle-based turbulence models, neoclassical transport, and edge coupled fluid and Monte-Carlo neutral modelling for the SOL and divertor (EDGE2D-Eirene). The core and edge are coupled through boundary conditions at the separatrix. Experiments are analysed, where light (e.g. N) and heavy (e.g. Kr) impurities are puffed into tokamaks to tailor the edge and core radiation profile profiles necessary for heat exhaust control vital in future machines, while avoiding H-L back-transitions. Extensive visits to the JINTRAC team at JET is envisaged for training and analysis tasks.
