Effect of disruptions on fuel release from JET walls

Funded under: FP7-EURATOM

Abstract

The amount and temporal behaviour of the fuel release from the JET walls has been analysed for normal and disruptive shots during the JET SRP divertor campaign (2002-2004 with about 8000 plasma shots). The averaged fuel release in the first 700 s after the shots for nondisruptive shots is 1.8 × 10{22} atoms compared with an averaged value of 3.7 × 10{22} for the disruptive shots. A clear and approximately linear increase of the released particles with the plasma stored energy at the time of disruption is found. Nondisruptive and disruptive shots can be clearly separated from the temporal evolution of the fuel release showing a slow particle release after nondisruptive and an instantaneous release after disruptive shots indicating thermally induced particle desorption after disruptions.
