Abstract

ITER will be the most important machine equipped with actively cooled Plasma Facing Components (PFCs). In case of abnormal events during a discharge, the PFC will be submitted to localized transient phenomena (high power densities, run away electrons, etc.), leading, in the worst case, to the degradation of the PFC wall and possibly to a water leak. In any case, a leak will have important consequences for the PFCs and equipments located in the vacuum vessels or connected to the ports such as seals, pumping systems or diagnostics. A great experience of these events has been gained at Tore Supra since more than 10 years and it will be useful for the next step machines
This paper presents the description of the procedures applied to put the system in safety depending on the gravity of the leak. It also presents the methods used at Tore Supra to drain off the primary loop circuits and to determine the leaky PFC.
