The Impact of Materials Composition and Irradiation Modelling on the Activation of ITER in Vessel Components
This paper presents the results of sensitivity studies aiming to assess the impact of AISI 316 ITER structural materials compositon on the activation characteristics of the in-vessel components. The influence of the protective layer material, namely beryllium, carbon fibre composite, and tungsten, is also anlaysed and discussed. The ANITA-2 and the FISPACT-3 activation codes are used, with updated cross sections and decay data libraries based on EAF-3 evaluation files. The 1D-Sn XSDRNPM-S transport code, using the 171 group VITAMIN-C library based on EFF-2 data, is used to produce the flux-weighted spectrum needed for the activation calculations. The outline design of ITER defined in the Fourth Meeting of the Technology Advisory Committee is considered for the assessment.
