Keywords : Heat loads * ITER * monoblock * shaping

Surface heat loads on several ITER monoblock design options are derived from physics-based modelling. Power flow into gaps, cassette body tilting, and monoblock shaping lead to important peak temperatures that can exceed the tunsgten recrystallization temperature during inter-ELM detached regime, and slow transient reattachment. Furthermore, the margin against global surface melting due to mitigated ELMs is lost.
