STEP WP5 - Fusion Power Plant - Diverter Heat Exchanger Design Challenge

Manging the heat exhaust from a fusion reactor is one of the most pressing challenges facing those seeking to realise a commercial power plant design. A fusion reactor heat exhaust is handled via a divertor, which needs to handle large heat fluxes (>10 MWm-2) especially in the divertor target. For spherical tokamak designs such as STEP, the compact nature of the device potentially increases the heat fluxes on the plasma-facing components, such as the divertor target, and restricts the space for incorporating coolin...
