Abstract: The issue concerning the structural integrity of materials is still playing a dominant role due to the degra-dation mechanisms, such as hardening, phase instability and embrittlement, which must be understood in order to estimate the component lifetime. In this paper we present some interesting results on few struc-tural materials pre-selected for Generation IV reactor concepts. The study is based on the application of non-destructive spectroscopic techniques, in particular positron annihilation spectroscopy combined with transmission electron microscopy to investigate advanced steels, as P91, T91 and. Analysis of experimen-tal results confirmed that P91 has indicated lower radiation stability than T91 and EUROFER 97 respectively.
