摘要：

Deuterium recycling during and after ohmic limiter discharges in the Be-phase of JET are compared with that during the C-phase. For the Be-phase, effective transport parameters for diffusion and recombination of deuterium at surfaces of in-vessel components of JET are derived using plasma discharge data only. This and the analysis of the outgassing behaviour after the discharge suggest that deuterium release is controlled by recombination with D/k (D is the diffusion, k the recombination coefficient) of about 10(21)-10(22) m-2, larger than expected from laboratory measurements.
