It is expected that the neutron wall loading in DEMO is larger than that in ITER, over 0.78 MW/m $^{2}$ . It is concerned that the decay heat due to the large neutron wall loading will lead to excessive temperature rising in blanket. In present study, the thermal response characteristics of blanket caused by the decay heat under LOCA were evaluated. In addition we considered how to effectively mitigate the excessive temperature rising based on the evaluation results.
