Abstract

The tritium balance based on pressure measurements has been performed on a shot by shot analysis during the plasma operations of the DTE1 campaign carried out at JET in 1997. This gives a complementary analysis to the integrated tritium inventory already reported for a full day of experiments. The particle balance shows that the T flux retention was of the order of about 1.26 10E21 T s {-1} during the plasma operations (approximately 65% of the injected flux). The outgasing between the pulses reduces this T inventory to about 30% of the injection. This detailed gas balance shows also that the retention of hydrogen species depends on the plasma isotopic ratio. However, during the D clean up pulses, the amount of T removed by isotopic exchange is shown to be limited to about 2 10E 23 particles. Finally, the total particle balance (D+T) is shown to be independent the plasma isotopic ratio.
