Finite element analysis has been used to optimise the geometry of the NET/ITER first wall for thermal loads and to compare the performances of cooling schemes with conductive and radiative tiles. The structural integrity and lifetime prediction for this component have been assessed by the elastic routes of the ASME and RCC-MR design codes; the lifetimes obtained vary from 2x1.0 E5 to E6 cycles according to the type of model used. To provide verification of these theoretical predictions, a testing programme at the thermal testing facility of the JRC Ispra has been initiated and the initial results from the testing of a first wall mock-up are presented.
