The potential of liquid-metal 3D-printed heat shields for fusion reactors

In 2020, the European DEMO fusion reactor completed its pre-conceptual design stage. This reactor succeeds ITER (first demonstration of net fusion energy, construction in full swing), and is scheduled for construction around 2040. Nevertheless, several design issues must be urgently resolved. One of these lies in the design of the plasma facing heat shields, the so-called Divertor.

A baseline divertor is being developed which can already withstand extraordinary heat flux densities. Yet, this design might still be instantly destroyed in case of an uncontrolled plasma instability. An alternative is therefore proposed: a liquid metal divertor (LMD). In this seminar we discuss how 3D-printed porous tungsten substrates for liquid metal accelerated LMD research at DIFFER, and the status of LMD concept development and testing for the EU-DEMO.
