abstract = {This study focuses on performing a multiphysics study using
the ERO2.0 and UEDGE codes for two standard double null
configurations for the Fusion Nuclear Science Facility: (a)
$100\%$ recycling and (b) $99\%$ recycling. Results show
that the main contributor to tungsten erosion along the
divertor plates is impurities from the midplane waveguides.
In addition, the standard high-recycling case $(100\%$
recycling) shows a significantly higher buildup of
impurities along the divertor tiles during the startup
phase, which can lead to a higher increase of energy loss in
the plasma during steady-state operation. Last, for high
recycling, anomalous diffusion can dominate over parallel
field diffusion. The work performed in this study can be
iteratively applied to a full operation scenario with
additional physics such as those from neutrals, wall
shaping, and additional external fields.},
