The divertor plate represents a critical component in the design of a tokamak fusion reactor. Within the frame of the International Tokamak Experimental Reactor (ITER), many proposals are underway. The thermal behaviour following a complete Loss of Coolant Accident (LOCA) of a pre-designed divertor plate is analysed in this paper. The aim is to carry out a parametric study on the most critical parameter, i.e. the plasma shutdown time. Several load hypotheses are studied in order to contribute to a better understanding of the design requirements for the components. According to these results, significant material damage is expected to occur if plasma burning is not stopped efficiently within a few seconds of the LOCA detection.
