Erosion estimates for the divertor and main wall components from STEP
Nuclear Fusion, 2023 The tungsten erosion within Spherical Tokamak for Energy Production (STEP) assuming tungsten main wall and tungsten divertor has been estimated with ERO at the inner and outer divertor, at the inner and outer midplane and at the outboard baffle entrance.

Plasma edge and plasma-wall interaction modelling: Lessons learned from metallic devices
Nuclear Materials and Energy, 2017 Robust power exhaust schemes employing impurity seeding are needed for target operational scenarios in present day tokamak devices with metallic plasma-facing components (PFCs). For an electricity-producing fusion power plant at power density Psep/R>15MW/

Impact of plasma-wall interaction and exhaust on the EU-DEMO design
Nuclear Materials and Energy, 2021 In the present work, the role of plasma facing components protection in driving the EU-DEMO design will be reviewed, focusing on steady-state and, especially, on transients. This work encompasses both the first wall (FW) as well as the divertor. In fact,

Integrated modelling: Coupling of surface evolution and plasma-impurity transport
Nuclear Materials and Energy, 2020 During the interaction of the scrape off layer (SOL) plasma with the first wall the evolution of both wall and plasma are tightly coupled: The erosion of the first wall leads to an impurity concentration in the plasma which affects the particle and power
