The effect of UV light irradiation on the removal of tritium from the codeposited carbon–tritium layer in fusion reactors

A series of experiments have been performed at the Karlsruhe Tritium Laboratory to examine the effects of UV light on tritium removal from the codeposited layers on carbon fiber composite tiles removed from the JET fusion device. Codeposited layers were exposed to UV light from a mercury lamp (254 nm) for various temperatures using air and argon atmospheres. Samples were also heated externally with no UV light to compare tritium release with and without UV exposure
