DUAL COOLANT LIQUID METAL BREEDER BLANKET

A blanket concept for a fusion DEMO-reactor combining self-cooling of the liquid metal breeder zone with helium-cooling of the first wall is described. Main emphasis has been placed on high safety and reliability features and on a simple, stiff blanket structure. Results of the analysis in the fields of neutronics, thermal-hydraulics and magneto-hydro-dynamics are reported.
