[Article] Thermal-Hydraulic Analysis of the EU DEMO Helium-Cooled Pebble Bed Breeding Blanket Using the GETTHEM Code

The GEneral Tokamak THErmal-hydraulic Model – GETTHEM has been updated to the most recent version of the EU DEMO Helium-Cooled Pebble Bed (HCPB) Breeding Blanket (BB) design. The GETTHEM results are first benchmarked in a controlled case against the results of 3D Computational FluidDynamics computations, showing an acceptable accuracy despite the inherent simplifications in the GETTHEM model. G...

Status of development of the EU He-cooled divertor for DEMO

A modular He-cooled divertor concept for DEMO is being investigated at Forschungszentrum Karlsruhe (FZK) within the framework of the EU power plant conceptual study. The design goal is to reach a heat flux of at least 10 MW/m. The reference design HEMJ (helium-cooled modular divertor with jet cooling) consists of a hexagonal tungsten tile which is brazed to a thimble made of W-1%La2O3. The cool...

Breeding blanket concepts for fusion and materials requirements

This paper summarizes the design and performances of recent breeding blanket concepts and identifies the key material issues associated with them. An assessment of different classes of concepts is carried out by balancing out the potential performance of the concepts with the risk associated with the required material development. Finally, an example strategy for blanket development is discusse...
