JET contribution to ITER fuel cycle issues

The Joint European Torus (JET) fusion machine is the only device capable of operation with tritium and Be, which makes it best suited to study ITER relevant issues. A large variety of activities are performed within the JET fusion technology task force. In this paper, some topics, such as erosion/deposition and material transport, flakes characterization and detritiation techniques, are highlighted. Recent results obtained using a pumping cryopanel and on plasma facing component (PFC) characterization, are given. Finally, issues that will be addressed in the forthcoming JET work-programme are presented, such as a beryllium main wall for JET and in situ laser detritiation.
