Synthesis, characterization, and properties of carbide dispersion-strengthened tungsten alloys for use as a plasma-facing material in nuclear fusion reactors
Tungsten is the material of choice for plasma-facing components in future plasma-burning fusion reactors because of its high melting point, high sputter threshold, and low hydrogenic species retention. However, tungsten is an intrinsically brittle material, displaying no room temperature ductility …

Sputter deposition and plasma modification of tungsten alloys for nuclear fusion applications
… device to demonstrate net fusion power. Critical plasma-facing components in the reactor will be made of tungsten, but helium plasma irradiation is known to embrittle tungsten metal. A future reactor will therefore need an alternative material to extend the lifetime of the components. This thesis …

Experimental and numerical analysis of thermoelectric magnetohydrodynamic driven liquid lithium flow in open channels for fusion applications
The concept of using molten metal as a plasma facing material (PFM) has been widely considered, and liquid lithium, among many choices, has attracted a lot of research interests in recent years. Compared to the traditional solid plasma facing component (PFC) a liquid lithium PFC may effectively …

The design and development of hydrogen isotope extraction technologies for a limit-style liquid lithium loop
As lithium has grown in popularity as a plasma-facing material, efforts have been placed on examining its viability as a first wall candidate. Lithium has proven over numerous studies to improve core confinement, while allowing access to operational regimes previously unattainable while using …

Thermal shock behaviour of different tungsten grades under varying conditions
… most critical issues is the field of in-vessel materials and components, in particular the plasma facing materials (PFM). PFMs that will be used in a device like ITER have to withstand severe environmental conditions in terms of steady state and transient thermal loads as well as high particle …
