In ITER, isotopic exchange is considered a potential method for recovering tritium that becomes trapped in components facing the plasma during deuterium-tritium plasmas. This involves creating plasmas fed solely by deuterium to replace the tritium trapped in the walls with deuterium…

The plasma-facing components of the divertor in a magnetic confinement fusion device such as WEST, and later ITER, consist of tungsten elements assembled onto a copper alloy cooled by water circulation. These centimeter-sized, parallelepiped-shaped elements line the bottom of the vacuum…
