Abstract :
Thermal-structure calculation are performed and the results are used to predict the lifetime of a possible ITER EPP blanket. The calculations, performed with the aid of a finite element analysis code, use the first wall configuration and coolant flow parameters of the helium cooled martensitic steel, European blanket design proposed for DEMO, but assume loading conditions anticipated in the ITER EPP. The calculations and analysis of the results suggest that the zero-fatigue lifetime (creep damage only) for low coolant temperature (315.5 C) is 6.2 years, and for high coolant temperature (375.0 C) is 3.08 years
