Abstract :
Operation of JET with a C/Be first wall has generated significant amounts of dust and deposit through plasma erosion processes and Be evaporation. The introduction of tritium in the Deuterium-Tritium Experiment (DTE1) under the Mk IIa divertor configuration has further resulted in deposits of tritiated flakes with specific activities in excess of 1 TBq/gram. The retention of large quantities of tritium in tokamaks is not only a problem for inventory control, but is also a major radiological protection issue
