Structural materials research is a field of growing relevance in the nuclear sector, especially for the

different innovative reactor systems being developed within the Generation IV International Forum

(GIF), for critical and subcritical transmutation systems, and of interest to the Global Nuclear Energy

Partnership (GNEP). Under the auspices of the NEA Nuclear Science Committee (NSC) the Workshop on

Structural Materials for Innovative Nuclear Systems (SMINS) was organised in collaboration with the

Forschungszentrum Karlsruhe in Germany. The objectives of the workshop were to exchange information

on structural materials research issues and to discuss ongoing programmes, both experimental and in

the field of advanced modelling. These proceedings include the papers and the poster session materials

presented at the workshop, representing the international state of the art in this domain.
