In 1959 the Journal of Nuclear Materials (JNM) was founded and is now celebrating its
Diamond Anniversary year. The present paper is part of a series in which single JNM …

In fusion reactors, surfaces of plasma facing components (PFCs) are exposed to high heat
and particle flux. Tungsten and Copper alloys are primary candidates for plasma facing …

The interaction processes between the burning plasma and the first wall in a fusion reactor
are diverse: the first wall will be exposed to extreme thermal loads of up to several tens of …

The tungsten (W) material in the high heat flux regions of the ITER divertor will be exposed
to high fluxes of low-energy particles (eg H, D, T, He, Ne and/or N). Combined with long …

Component development for operation in a large-scale fusion device requires thorough
testing and qualification for the intended operational conditions. In particular environments …

Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads
to tolerable heat and particle loads on the wall is a major challenge. The new European …

The Magnum-PSI facility is unique in its ability to produce and even exceed the heat and
particle fluxes expected in the divertor of a fusion reactor, combined with good access to the …

In ITER and future tokamaks, recrystallization has been identified as an important issue
which may reduce the strength of tungsten plasma-facing component and deteriorate its …

Tungsten-potassium (WK) alloys are regarded as one of the candidates for plasma-facing
materials (PFMs) intended for the divertor and first wall of future fusion reactors. Determining …

The effect of helium (He) plasma exposure, and associated surface modifications, on the
thermal shock resistance of tungsten (W) under ITER relevant steady state and transient …
