DEMO Divertor Target Mock-Ups With Tungsten-Fiber-Reinforced Tungsten Monoblocks

F. Crea, S. Roccella, D. Caprini, M. Cerocchi et autres

Within the EUROfusion Consortium, in the context of the workpackage materials (WPMATs), tungsten-fiber-reinforced tungsten composite (Wf/W) materials have been developed to overcome the intrinsic brittleness of pure W as a potential plasma-facing material (PFM) for the European demonstration fusion power plant (EU-DEMO). …

Overview of the ASDEX Upgrade results

T. Pütterich, Felix Albrecht, Edoardo Alessi, Sehoon An et autres

Abstract After a 26-month vent ASDEX Upgrade (AUG) went back in operation with a newly designed upper W-divertor suitable for alternative divertor configurations (featuring in-vessel coils and cryo-pump). Parameter scans and an extensive set of measurements were obtained and their interpretation is …

Effect of neutron irradiation on the fracture behaviour of tungsten fibre-reinforced tungsten composites

J. Riesch, Aleksandr Zinovev, E. Gaganidze, H. Ries et autres

• Fracture mechanics tests of neutron irradiated W fibre-reinforced W composites • Bulk material produced by chemical vapour deposition (CVD) and powder metallurgy (PM) • Short fibre material produced by PM shows degradation but keeps limited toughness • Long fibre material produced …
