Abstract
Accelerator mass spectrometry (AMS) and the full
combustion method (FCM) followed by liquid scintillation
counting were applied to quantitatively determine the
tritium retention in the tungsten-coated carbon fibre
composites (CFC), in comparison to uncoated CFC tiles
from the JET divertor. The tiles were adjacent and
exposed to plasma operations between 2007 and 2009. The
tritium depth profiles are showing that the tritium
retention on the W-coated tile was reduced by a factor of
13.5 in comparison to the uncoated tile whereas the bulk
tritium concentration is approximately the same for both
tiles.
